1-8 )

1-1 Functions of Tiered Storage Manager

Tiered Storage Manager is designed to relocate (migrate) data from one volume on a storage subsystem to another volume. You can migrate data simply by specifying the relocation destination. (Tiered Storage Manager does not migrate data to a tape device.) See migrate using Tiered Storage Manager.

1-1 )

1-5 )

1-7 )

Figure 1-1 for an illustration of the scope of data you can

Using Tiered Storage Manager offers the following advantages:

• You can migrate data without interrupting the current application.

• You can migrate data without being aware of the storage configuration.

• You can migrate multiple volumes at once.

• You can reduce the preparation time for a migration.

• You can use multiple storage subsystems as though they were a single storage subsystem and centrally

manage different types of storage environments, since Tiered Storage Manager uses the StorageWorks XP12000/10000.

• You can migrate data in line with the concept of Data Lifecycle Management (DLCM) so that data used

frequently is stored in high-performance storage and data used less frequently is stored in lowperformance storage. See

Figure 1-2 for an illustration of migrating data according to DLCM.

Using Tiered Storage Manager 11

Figure 1-1 Scope of Data Eligible for Migration

Figure 1-2 Data Migration according to Life Cycle Management

1-1-1 Migrating Data without Interrupting Your Current Application

When you use Tiered Storage Manager to migrate data, you do not have to be aware of changes to the storage configuration or to the volume containing the data being migrated. You can access the migrated data in the same way as before migration. Even during migration, you do not have to interrupt an application.

1-1-2 Grouping and Migrating Volumes

You can define a group of storage volumes in advance, so that they are migrated at the same time. By giving the group an appropriate name , and by setting an explanation of the group as an attribute, you can easily identify the group of volumes to be migrated.

You can also prevent a group of volumes from migrating accidentally by disabling migration for that group.

1-1-3 Defining Migration Target Volumes

You can define a group of target volumes in advance for a particular purpose, such as access speed, reliability or bit cost. In response to a request from a user, you can also migrate data whose usage value has dropped from a high-performance storage subsystem to a low-performance storage subsystem. You can select the group you need when you are migrating data to suit your specific requirements without having to specify any detailed conditions. Such volume groups can be created, for example, on a storage subsystem, CLPR, or array group basis.

1-1-4 Using the External Storage Connection Function

Using the external storage connection function of StorageWorks XP12000/10000, you connect to various types of storage subsystems using fiber channels, thereby integrating the subsystems into a single virtual storage subsystem. You select volumes within this storage subsystem as the migration source or target. This means you can migrate data without worrying about the different types of storage subsystems.

1-1-5 Using HTSM With Clients

You can use Tiered Storage Manager with two types of clients:

• Web client: This client enables you to operate Tiered Storage Manager on a browser. For details about

the window, click the Help button on the window and refer to the displayed Tiered Storage Manager GUI Help.

• Command Line Interface (CLI) client: This client directly operates the command line, so you can batch

operations such as migration. Refer to the HP StorageWorks XP Tiered Storage Manager CLI Reference Guide for details.

1-2 Deciding When to Migrate Data

Migrating data helps increase the efficiency of an entire storage system. You can decide to migrate data:

• When the importance of data changes

• When storage performance needs to be improved

• When the storage environment changes

Tiered Storage Manager migrates data between storage subsystems.

NOTE: In this manual, the term domain controller refers to the following products

•

StorageWorks XP12000/10000

• StorageWorks XP10000

1-2-1 When the Importance of Data Changes

You can migrate data in line with the concept of Data Lifecycle Management (DLCM), so that data used frequently is stored in high-performance, high-price storage and data used less frequently is stored in lowperformance, low-price storage. You can migrate data between high- and low-performance storage subsystems, depending on how often it is used.

Using Tiered Storage

Manager

Figure 1-3 illustrates migration according to the life cycle of data.

Figure 1-3 Migration Suited to the Life Cycle of Data

1-2-2 When Improving Storage Performance

You can migrate data to improve storage performance if multiple volumes with high-access frequency in the same array group become overloaded, if a storage subsystem reaches a bottleneck, or if data outlives the life of the storage system.

Migration in a domain controller is illustrated by

Figure 1-4 Migration in the Domain Controller

Figure 1-5 and Figure 1-6 illustrate migrating data to redistribute access load and improve storage performance.

Figure 1-4

Figure 1-5 Migrating Data to Redistribute Access Load (before migration)

Using Tiered Storage

Manager

Figure 1-6 Migrating Data to Redistribute Access Load (after migration)

Figure 1-7 illustrates migrating data by rearranging the storage subsystems.

Figure 1-7 Migration by Rearranging Storage Subsystems

After you have installed a higher performance storage subsystem, you can migrate data with a high usage frequency to high-performance storage.

Figure 1-8 illustrates migration from an external storage subsystem to the domain controller.

Figure 1-8 Migration from an External Storage Subsystem to the Domain Controller

1-2-3 When the Storage Environment Changes

When data is to be held for a long period, the storage subsystem may reach the end of its life cycle before the data does.

In this case, you can migrate the data to a different storage subsystem before the first storage subsystem reaches the end of its life cycle.

Figure 1-9 Migration Between Two External Storage Subystems

1-3 How Migration Works

Tiered Storage Manager allows you to migrate data located on a volume within the scope eligible for migration without being aware of the change in LDEV number. After performing a migration, Tiered Storage Manager changes the LDEV number automatically so that you do not have to change the access path to the host, which prevents any interruption of an application service. Tiered Storage Manager migrates data in units of volumes.

You can migrate data between any storage subsystems as long as they are within the migration scope.

Migration consists of five processing steps:

1. After you create a migration task, you reserve a migration target volume. The reserved volume is not

accessible from a host.

2. When the execution of a migration task starts, Tiered Storage Manager copies data from the migration

source volume to the migration target volume

3. Tiered Storage Manager switches the LDEV number of the migration source volume with the LDEV

number of the migration target volume. A volume reservation is performed for an LDEV number. Thus, the volume reservation moves from the migration source volume to the migration target volume just as the LDEV numbers are switched

4. The volume reservation is removed. A volume reservation is also removed when a migration task is

canceled, or a migration task fails to execute. If removal of the volume reservation fails, refresh the storage domain to remove it.

5. Tiered Storage Manager erases the data from the migration source volume when you select that option.

Figure 1-10 shows the relationship between volumes and LDEV numbers in volume reservation, LDEV number switching, and data erasure

Figure 1-10 Relationship between Volumes and LDEV Numbers

1-4 Methods of Migration

This section describes three methods of migration:

• Migration within a domain control storage subsystem.

• Migration between a domain control storage subsystem and an external storage subsystem.

• Migration between two external storage subsystems.

1-4-1 Migration within a Domain Control Storage Subsystem

You can migrate data within a control storage subsystem to distribute access load, as shown in Figure 1-11 below.

Figure 1-11 Migration within a Domain Control Storage Subsystem

1-4-2 Migration Between Domain Control Storage and External Storage Subsystems

You can migrate data from a domain control storage subsystem to an external storage subsystem, or from an external storage subsystem to a domain control storage subsystem. You do this when a high-performance storage subsystem has been added. Figure 1-12 illustrates this method of migration.

Figure 1-12 Migration Between Domain Control Storage Subsystem and External Storage Subsystem

1-4-3 Migration Between Two External Storage Subsystems

You can migrate data between two external storage subsystems connected to separate domain control storage subsystems. You do this when an external storage subsystem is full. migration.

Figure 1-13 illustrates this method of

Figure 1-13 Migration Between Two External Storage Subsystems

1-5 Required Components of Migration

The following four components are required for migration in Tiered Storage Manager. Table 1-1 describes these components and their related operations and refers you to chapters or sections in this manual where you can find more detailed information.

Table 1-1 Required Migration Components

Required Component Operation Chapter or Section

Storage domain

Refers to either a domain control storage subsystem, or a domain control storage subsystem connected to an external storage subsystem. You can create only one storage domain for each domain control storage subsystem. You can migrate data only between volumes in the same storage domain.

Storage tier

1-6-3 Using Tiered Storage Manager with PSAs

Logical Partition (LPAR) is the generic name for the Cache Logical Partition (CLPR) and Storage Logical Partition (SLPR) functions.

Tiered Storage Manager uses an SLPR administrator in addition to the administrator for the entire storage subsystem. The SLPR administrator is called the Partition Storage Administrator (PSA).

In some cases, when a Device Manager user registered in Storage Navigator as a partition storage administrator (PSA) adds a domain controller to Device Manager, the domain controller added to Device Manager is called a domain controller for which the PSA is managing SLPR operations.

A domain controller for which the PSA is managing SLPR operations cannot be used as a storage domain for Tiered Storage Manager.

Guest

Do not change a domain controller that Storage Administrator has registered in Tiered Storage Manager to a domain controller for which the PSA is managing SLPR operations on Device Manager. In addition, in the storage subsystem that performs LPAR operations, a candidate for the migration target volume is selected from within the LPAR to which the migration source volume belongs. In a domain controller managed by the Storage Administrator, a migration can be performed for volumes that have overlapping LPARs.

For details on the CLPR and SLPR, see the manual HP StorageWorks Command View XP Advanced Edition Device Manager Web Client User's Guide or the Virtual Partition Manager User's Guide.

1-7 Performing a Refresh

When you change storage configurations or finish performing a migration, you must update —meaning refresh — information to reflect the latest status. You can view the latest refresh date and time in the List Objects – Storage Domain Name subwindow of the Web client. You cannot perform most Tiered Storage Manager operations during a refresh. This section describes the refresh operation, including:

• How Refresh Works

• When to Perform a Refresh

• Refresh Types and Scopes

• Refresh Status Information

• Using Refresh to Detect Inconsistencies

1-7-1 How Refresh Works

Performing a refresh takes time because it updates repositories and cache information.

The repositories are databases that manage setup information for Tiered Storage Manager, Device Manager, and Command View XP AE Suite Common Component. The repositories are managed by Command View XP AE Suite Common Component.

The repository types are:

• Repository for Tiered Storage Manager: Manages information defined for migration and the status of the

Tiered Storage Manager server.

• Repository for Device Manager: Manages system and hardware information about storage subsystems

managed by Device Manager.

• Repository for Command View XP AE Suite Common Component: Common to all Command View XP AE

Suite software. It manages data displayed in display areas common to Web client series products. If a Web client or CLI client gives an instruction to perform a refresh, this repository does not change.

The cache is information that is imported from the Device Manager repositories to a database (repository) for Tiered Storage Manager.

1-7-2 When to Perform a Refresh

You must perform a refresh:

• After changing logical device or hardware configurations (see section

• After registering or performing a migration task (see section

NOTE: Tiered Stored Manager automatically performs a refresh when you add or delete a storage domain.

You cannot perform a refresh:

• If a storage domain is managed with PSA permissions (an error message displays).

• During another operation, including another refresh (an error message displays).

NOTE: It takes some time to refresh the Tiered Storage Manager storage domain because the refresh

operation updates the database (repositories).

1-7-2-2 ).

1-7-2-1 After Changing Logical Device or Hardware Configurations

1-7-2-1 ).

If you do not perform a refresh after changing configurations, data will be migrated to the wrong location.

Example:

a. LDEV 2:01 is externally connected to StorageWorks XP1024.

b. A refresh is performed by using Tiered Storage Manager.

c. The external connection target of 2:01 is changed to StorageWorks XP512 by using Remote Web

Console.

d. 2:01 is migrated by using Tiered Storage Manager.

In the Web client display, 2:01 still matches StorageWorks XP1024. The migration target of 2:01 still appears to be StorageWorks XP1024. However, migration to StorageWorks XP512 has actually been performed.

1-7-2-2 After Registering or Performing a Migration Task

If you do not perform a refresh after registering or performing a migration task, an error might occur in the subsystem.

NOTE: After you perform a refresh, the latest refresh data and time display in the List Objects – Storage

Domain Name subwindow. The information in the navigation frame is also updated.

1-7-3 Refresh Types and Scopes

There are four refresh operation types:

• Refresh to synchronize information in the storage subsystems with the repository for Device Manager

• Refresh to synchronize the repository for Device Manager with the repository for Tiered Storage Manager

• Refresh to synchronize the repository for Tiered Storage Manager with the HiCommand common

repository

• Refresh to synchronize the HiCommand common repository with the browser

Performing a refresh to synchronize information in the storage subsystems with the repository for Device Manager

This refresh synchronizes information in the storage subsystems with the storage subsystem configurations held by Device Manager.

If an attempt is made to refresh Tiered Storage Manager when an inconsistency exists between the information in the storage subsystems, the storage configuration information held by Device Manager, and the storage configuration information held by Tiered Storage Manager, a message asking whether you want to refresh Device Manager is displayed. Click the OK button if you want to refresh Tiered Storage Manager and Device Manager.

The refresh scope of Device Manager is the domain controllers that contain the storage domain that is the refresh target of Tiered Storage Manager.

For details on performing a refresh to synchronize information in the storage systems with the repository

for Device Manager, see 1.6.4 Refreshing Device Manager Repositories.

Performing a refresh to synchronize the repository for Device Manager with the repository for Tiered Storage Manager

This refresh synchronizes the storage subsystem configurations held by Device Manager with the storage subsystem configurations held by Tiered Storage Manager.

This refresh is executed when a storage subsystem configuration (such as an LDEV configuration) is changed in Device Manager or Remote Web Console. The refresh scope is the migration target storage domain.

The refresh is the Refresh displayed in the method frame (Web client) or a refresh executed by the

Refresh command (CLI client).

Performing a refresh to synchronize the repository for Tiered Storage Manager with the Command View XP AE Suite Common Component repository

This refresh synchronizes the storage domain and storage tier objects held by Tiered Storage Manager with the Tiered Storage Manager objects (for tree display) held in the Command View XP AE Suite Common Component repository.

A refresh is automatically executed when the Tiered Storage Manager server starts. When the Tiered Storage Manager server is abnormally terminated during update processing of the repository for Command View XP AE Suite Common Component, all storage domains in Tiered Storage Manager are

refreshed.

Performing a refresh to synchronize the HiCommand common repository and the browser

This refresh synchronizes the Tiered Storage Manager objects (for tree display) held in the Command View XP AE Suite Common Component repository with the tree displayed by the browser.

Execute this refresh by choosing Refresh in the menu bar frame. The refresh scope is the added storage domain.

1-7-4 Refresh Status Information

When you have created or deleted a storage domain, Tiered Storage Manager automatically refreshes information. At this time, there are four possible refresh statuses:

• Status in which a refresh has not been performed: Indicates the status immediately after creating a

storage domain (before performing a refresh). After creating a storage domain, Tiered Storage Manager automatically performs a refresh. If the automatic refresh fails, perform another refresh.

• Normal status (refresh-successful status): Indicates that the refresh was successful and that the

repository and cache are normal.

• Refresh in progress status: Indicates that a refresh is being performed.

• Cache abnormal status (refresh-failed status): Indicates that the refresh failed due to an error and that the

status of the repository or cache is abnormal.

1-7-5 Using Refresh to Detect Inconsistencies

If an error occurs in the network or storage device when a migration task is created, performed, or cancelled, the following three types of information may become inconsistent:

• Information within the storage subsystems

• The repository for Device Manager

• The repository for Tiered Storage Manager

You can detect these inconsistencies, by refreshing the information after migration finishes (the status of the migration task is Success, Failure, or Cancel.). If you try to refresh Tiered Storage Manager while the repository is inconsistent, a message asking whether you want to refresh Device Manager is displayed. Click OK if you want to refresh Tiered Storage Manager and Device Manager.

The refresh scope on Device Manager is the domain controllers that make up the storage domain that is the refresh target on Tiered Storage Manager.

1-8 Volumes Used for Migration

Migration source and target volumes must satisfy the following conditions in a migration using Tiered Storage Manager:

• The emulation types of the migration source volumes and migration target volumes match.

• The sizes of the migration source and migration target volumes match.

The emulation types of the migration source volumes and the migration target volumes are not OPEN-V, but the volumes are both CVS or both normal.

You can check the emulation type and size of a volume in the Volume Detailed Information – Device Number popup window. For details on this window, see the GUI Help.

• Volumes that cannot be migrated

For volumes that cannot be migrated, you can check the status from the Volume Detailed Information Device Number pop-up window - Can Migrate or Volume Status.

Can Migrate

When Yes is specified for Can Migrate, you can perform migration using the volume as a source volume.

When No is specified, you cannot perform migration using the volume as a source volume. An error occurs when you click the Migration button.

Volume Status

When Unused is specified for Volume Status, it is available as a source target.

When Used is specified, the volume will not be displayed as a candidate for the migration target volume.

When No is specified for Can Migrate, or Used is specified for Volume Status, the reasons are displayed in Reasons that a volume cannot become source/target volume in the Volume Detailed Information - Device

Number pop-up window. For details on the character strings to be displayed and their descriptions, see Table

1.5 Character Strings Representing Reasons a Volume Cannot Be a Migration Source or Target, and a

Description of those Character Strings.

• Volumes that cannot be checked for migration suitability

The following volumes cannot be checked for suitability by using Can Migrate or Volume Status. An error occurs when executing a migration task with these volumes selected as a source volume. Also, an error occurs when creating a migration task that has these volumes selected as migration target volumes.

• A volume that makes up a Cross-system Copy pair

• A volume that is the target of XRC (Extended Remote Copy, which is the IBM remote copy function)

• A volume that is the target of Concurrent copy

• A volume that cannot be accessed because it has a blocked status or is being formatted

An error occurs when executing a migration task using the following volumes together:

• For a migration source volume: volume made up of a TrueCopy pair

• For a migration target volume: externally connected volumes

• Information displayed as reasons that a volume cannot be a migration source or target

When migration suitability checks can be performed from Tiered Storage Manager, if volumes are determined to be unsuitable as a migration source or target, the reasons are displayed in Reasons that a volume cannot become source/target volume in the Volume Detailed Information - Device Number pop-up window.

The following table shows the character strings representing the reasons that a volume cannot be a migration source or target.

Volumes that can be checked by Tiered Storage Manager, and for which a migration task or data deletion task is being executed, are not displayed in Reasons that a volume cannot become source/target volume. Such volumes cannot be used as either migration source volumes or migration target volumes.

When the migration source volume is a LUSE, you can specify only those volumes that are not applicable to Table 1-4 Character Strings Representing Reasons a Volume Cannot Be a Migration Source or Target. In addition, the volume must satisfy the following conditions:

• All migration target volumes are made up of either internal or external volumes.

• If they are external volumes, the external volume attributes (emulation type, IO suppression mode, cache

mode, and CLPR) are identical.

Although they are not required, it is recommended that the following conditions be satisfied. If they are not satisfied, errors might occur during operation after migration is performed.

• All migration target volumes have the same RAID level.

• All migration target volumes have the same drive type, either SATA or non-SATA.

• For external volumes, all volumes are in the same chassis.

When the migration source volume LUSE is migrated, each LDEV in the migration target volume will make up a LUSE and be replaced with the migration source. Figure 1-14 shows migration of a LUSE configuration.

2-1 Preparing for GUI Operations

Before starting Tiered Storage Manager operation, you must check the following:

Storage Subsystem

All the storage subsystems being managed by Tiered Storage Manager must be connected by a LAN, and must be accessible from the Tiered Storage Manager's management server and management clients.

A storage subsystem being used as a domain controller must be connected to the external subsystem, and a logical device within that external subsystem must be mapped to the domain controller.

The term “domain controller” in this user’s guide refers to the StorageWorks XP12000 and the StorageWorks XP10000.

Device Manager server

The Device Manager server must be installed and set up in advance so that it is fully ready for use. For more information, refer to the HP StorageWorks Command View XP Advanced Edition Device Manager Server Installation and Configuration Guide.

Tiered Storage Manager server

The Tiered Storage Manager server must be installed and set up in advance so that it is fully ready for use. For more information, refer to the HP StorageWorks XP Tiered Storage Manager Server Installation and Configuration Guide.

Browser

Check the name and version of the browser you are using:

• If your OS is Solaris

• If your OS is Windows

Internet Explorer with Windows

If you are using Internet Explorer with Windows up window not opening. In such cases, do the following for the connection-target server:

1. From the Internet Explorer Tools menu, select Pop-up Blocker, and then Pop-up Blocker Settings.

2. Type the address (URL) of the connection-target server in the Address of Web site to allow box, and then

click Add.

If the registration processing ends successfully, the server will be added and displayed in the Allowed sites box.

Internet Explorer and Displayed Fonts

If you specify a font size in Internet Explorer to one other than medium, it might display differently during processing from what you have specified. When display processing finishes, the fonts will display in the size you specified. This does not affect operations.

Language Used for the Tiered Storage Manager GUI

The language you use for the Tiered Storage Manager GUI depends on the language setting for the browser you are using. The date format also depends on the language setting for your browser.

The time is always displayed in 24-hour format, regardless of the browser's language setting.

Getting Started with the GUI 28

However, the language being used by the OS and browser determines the language used for the Browse button, which is displayed in the Tiered Storage Manager version information dialog box, as well as the language used for the license file selection dialog box, which you open by clicking the Browse button.

An error message might contain text that remains unchanged after being received from the Device Manager server. The language type for these parts of a message is determined according to the location of the machine where the Device Manager server is running. We recommend that you match the language type for a Web client to the location on the server side.

2-2 Guidelines for Using Tiered Storage Manager GUI

To make sure that the Tiered Storage Manager GUI works correctly, you should avoid doing the following:

• Do not click the Next or Back buttons of the browser.

• Do not select an item in the menu opened by a right-click in a window.

• Do not use a shortcut key, such as Back Space or Tab.

• Do not select a menu-bar item in the browser window.

Note, however, that even if you inadvertently perform such an operation, the database (repository) that is used internally by Tiered Storage Manager will not be corrupted. If you inadvertently perform one of the above operations, do the following:

• If your browser is Internet Explorer, click Refresh on the View menu in the browser window. This re-

displays the window that was displayed immediately after login.

• If your browser is Netscape Navigator

window. This re-displays the window that was displayed immediately after login.

3 Creating a Storage Domain

This chapter describes how to create a storage domain.

• About Storage Domains (section

• Storage Domains and Migration Groups (section 3-2 )

• Creating a Storage Domain (section

For information on displaying a list of storage domains, changing attribute information and deleting storage domains, see

8 .

3-1 About Storage Domains

A storage domainis a grouping of one or more of the following subsystems:

• StorageWorks XP12000

• StorageWorks XP10000

• Storage subsystem externally connected to StorageWorks XP12000

• Storage subsystem externally connected to StorageWorks XP10000

Tiered Storage Manager operates and manages each storage domain, so migration is performed between volumes in the same storage domain.

Only one storage domain can be created for each domain controller. In other words, a single domain controller is used in one Tiered Storage Manager server.

You can use multiple domain controller on a single Tiered Storage Manager server. Each storage domain name must therefore be unique within its Tiered Storage Manager server.

You cannot delete or change the attribute information of a storage domain while the status of a migration task is Active or Standby.

If you create or delete a storage domain, Tiered Storage Manager automatically refreshes information. For information on the Refresh operation, see

3-1 )

3-3 )

1-7 Performing a Refresh.

A Partition Storage Administrator (PSA) cannot create a storage domain for a domain controller that manages Storage Logical Partition (SLPR) operations.

Only the System Administrator and Storage Administrator can create, change, or delete a storage domain. The System Administrator, Storage Administrator, and Guests who have access privileges can reference storage domains.

You can create a storage domain by specifying the following attributes:

• Storage domain name.

• Description.

• Model and serial number of the domain controller , or domain controller name.

When you create a new storage domain, information is refreshed.

3-2 Storage Domains and Migration Groups

A migration group is a group of volumes that are collectively migrated in one operation. This means that volumes in a migration group have the same characteristics (volumes which store databases for a certain business system, etc. ).To create a migration group, use search conditions to search the volumes in a storage domain or in a storage tier, and then select and register the desired volumes from those found.

Multiple migration groups can be created in a storage domain. An unlimited number of storage domains can be created in a migration group.

Permission to perform migration can be set for any migration group. If you want to protect a group of volumes from being accidentally migrated, create a migration group that contains these volumes, and then specify No for Can Migrate.

Note that when a storage domain is deleted, the migration groups within that domain are also deleted. Volumes and migration tasks within the deleted migration group, however, are not deleted.

Creating a Storage Domain 35

3-3 Creating a Storage Domain

You can create a storage domain as a migration range. When creating a storage domain, you must specify a domain controller. When there are no addable domain controllers, an error is displayed.

If an attempt to create a storage domain fails, re-create the storage domain. After a storage domain is created, Tiered Storage Manager automatically starts to perform a refresh. Sometimes the refresh fails, but if this happens, perform the refresh again.

To create a storage domain:

1. In the navigation frame, select the Storage Domains object.

The method frame displays the Create Storage Domain method.

2. Select the Create Storage Domain method in the method frame.

The Create Storage Domain pop-up window displays, as shown in

Figure 3-1.

3. Enter the following information in the Create Storage Domain pop-up window:

Name (required)

Enter a storage domain name of up to 75 bytes of UTF-8 characters.

You can use non-ASCII characters, and the following ASCII characters:

A to Z a to z 0 to 9 - _ . @ and a single-byte space

Do not use spaces for the first or last character of the name.

An error occurs if:

You do not enter a Name.

The character string for Name is too long.

You enter an invalid character for Name.

Domain Controller

Select a domain controller (domain control storage subsystem). Domain controllers (domain control storage subsystems) that perform SLPR operations with PSA permissions are not displayed.

Description

Enter a description of the storage domain you are creating of up to 500 bytes of UTF-8 characters.

If you enter 501 bytes or more in UTF-8 encoding for Description, an error occurs.

4. Click the OK button.

The Create Storage Domain-Processing pop-up window displays (clicking the x (Close) button at the top right corner of the screen does not stop processing). When processing ends, a new storage domain is created and the Create Storage Domain-Result pop-up window displays the execution result.

5. Click the Close button.

Information about the storage domain is refreshed, and the navigation frame refreshes. If a storage domain list was displayed in the information frame, it is updated.

About UTF-8 Characters

The maximum number of characters you can enter in the Name and Description columns is limited to the specified number of permitted bytes in UTF-8 encoding. One ASCII character equals 1 byte in UTF-8. Other characters are from 1 to 3 bytes in UTF-8.

4 Creating a Storage Tier

This chapter describes creating a storage tier and includes the following sections:

• About Storage Tiers (section

• Storage Tier Operations (section 4-2 )

• Creating a Storage Tier by Selecting the Storage Tiers Object from a Storage Domain (section

• Creating a Storage Tier Based on a Storage Domain Volume Search (section

For information about viewing a list of storage tiers, searching volumes and changing attribute information, see

9 .

4-1 About Storage Tiers

Set filter conditions for target volumes (such as the array group or RAID level) as the definition of certain storage tiers. This allows you to select volumes that match those filter conditions for the migration destination when you perform a migration. For more information on volume filter conditions, see Conditions.

You can create multiple storage tiers within a storage domain. The maximum number of storage tiers you can create within a single storage domain is 100. If you create 101 or more storage tiers, operation of Tiered Storage Manager cannot be guaranteed.

When you create a storage tier, or when you update an existing storage tier, the storage tier is defined with the specified volume filter conditions.

• Define by using conditions that can be used for the definition of storage tiers. This means that LDEV

numbers or volume statuses cannot be used to define storage tiers.

• Define by using and or or for all conditions.

Examples of creating a storage tier are as follows:

Example 1: When creating a storage tier for each storage subsystem

4-1 )

4-3 )

4-4 )

5 . Applying Filter

Select Storage Subsystem from the volume filter conditions. If you select StorageWorks XP12000/XP10000 as a filter condition, StorageWorks XP12000/XP10000 is created as the storage tier.

Example 2: When creating a storage tier for a CLPR

Select CLPR from the volume filter conditions. If you set CLPR1 as filter condition 1 and CLPR0 as filter condition 2, and then search volumes on the combination of conditions 1 and 2 by OR, all volumes in CLPR1 and 2 are displayed. Every volume can be created in a separate storage tier. If you set CLPR1 as a filter condition, a storage tier for CLPR1 is created.

Example 3: When creating a storage tier for an array group

Select Array group from the volume filter conditions. If you set Array group 1-1-1 for filter condition 1, Array group 1-2-1 for filter condition 2 and Array group 1-2-2 for filter condition 3, and then search volumes on the combination of condition 1-3 by OR, all volumes in array group 1-1-1, 1-2-1 and 1-2-2 are displayed. All the volumes can be created as a storage tier. If you set Array group 1-2-2 as a filter condition, a storage tier for Array group 1-2-2 is created.

A storage tier name must be unique within its storage domain. When creating a storage tier that includes a LUSE volume, make sure that the LUSE volume is in no more than one storage tier. If the LUSE volume is in more than one storage tier, see

Volumes from one storage tier can also be included in another storage tier. Even if a volume filtered by volume filter conditions is different, there is no problem.

Figure 4-1 illustrates the relationship between storage tiers and volumes.

Table 12-3.

Creating a Storage Tier 38

Figure 4-1 Storage Tiers and Volumes Relationship

When you delete a storage domain, the storage tiers within the deleted storage domain are also deleted at the same time. Volumes within the storage tiers and migration tasks that are related to the storage tiers are not deleted, however.

When an operational targeted storage tier belongs to a storage domain that is being refreshed, you cannot operate the storage tier. In addition, if the status of a migration task of an operation target storage tier, which is specified as the migration target, is Active or Standby, you cannot delete the storage tier or change its attribute information.

4-2 Storage Tier Operations

Storage tier operations include creating a storage tier, deleting a storage tier, referencing the list of storage tiers, referencing properties of a storage tier, changing attribute information for a storage tier, and searching volumes within a storage tier.

Only the System Administrator and Storage Administrator can create, change attribute information for a storage tier, or delete a storage tier. The System Administrator, Storage Administrator, and Guests who have access privileges can reference storage tiers.

If the storage domain containing the storage tier to be operated is currently refreshing, you cannot operate the storage tier. In addition, you cannot create or delete a storage tier or change attribute information for a storage tier while the status of a migration task is Active or standby.

There are two methods for creating a storage tier:

• Creating a storage tier by defining its name and filter conditions in advance.

4-3 Selecting a Storage Tier Object within a Storage Domain and Creating a Storage Tier.

See

• Searching volumes and then creating a storage tier from the search result

4-4 Creating a Storage Tier from the Search Result for Volumes within a Storage Domain.

See

For each storage tier, you can specify a storage tier name, filter conditions, and description of the storage tier. The storage tier name must be unique within its storage domain. You can change the filter conditions for a storage tier by changing the attribute information.

5 Applying Filter Conditions

Tiered Storage Manager allows you to specify and apply filter conditions to help you identify and classify data you are migrating more easily. You can specify up to 30 volume filter conditions, using various types of attributes of volumes in a storage subsystem as condition elements.

For volume filter conditions, the condition elements that can be used in a Web client are as follows:

• Creating a storage tier in a storage domain.

Specify volume filter conditions when creating a storage tier. These become part of the definition of the storage tier. You can change the definitions later, by changing the filter conditions.

• Selecting a migration target volume from the storage tier.

Specify volume filter conditions during a migration operation. Tiered Storage Manager selects a migration target candidate volume that matches the filter conditions, from the storage tier.

• Viewing a list of volumes in a storage domain or storage tier.

You can view a list of volumes that match the specified filter conditions. You can check volume locations or attributes from the list.

You can use the following condition elements from the Web client:

• Conditions where only one condition element is specified.

• Conditions where multiple condition elements are combined by AND.

• Conditions where multiple condition elements are combined by OR.

5-1-1-1-1Notes on volume filter conditions

The following are notes on volume filter conditions.

Creating a Storage Tier

• When creating a storage tier, you cannot use the LDEV, the volume status, the host, or the volume lock

status as filter conditions.

• If you specify server.checkOutVolumeRange = false in the properties file (server.properties),

single-byte spaces and upper - and lower-case characters are used as volume filter conditions exactly as they are entered. For details about the server.properties file, refer to the HP StorageWorks XP Tiered Storage Manager Server Installation and Configuration Guide.

6 Creating a Migration Group

This chapter describes creating a migration group and includes the following sections:

• About Migration Groups (section

• Creating a Migration Group by Selecting the Object in a Storage Domain (section 6-2 )

• Creating a Migration Group from Storage Domain Volume Searches (section

• Creating a Migration from Storage Tier Volume Searches (section

For information on how to display a list of migration groups, change attribute information, and add volumes, see

10 .

6-1 About Migration Groups

A migration group is a group of migration source volumes that have the same characteristics (such as disk type, RAID level, and array group) and are related to the same job.

A migration group is created by specifying filter conditions, and then registering the volumes that match those conditions. For details on volume filter conditions, see

Volumes from one migration group cannot be included in another migration group. Volumes from a migration group can be included in a storage tier, however.

You can specify whether a migration group is eligible for migration. If you have created a migration group that contains a group of volumes that must not be migrated, you can prevent accidental migration by setting Can Migrate to No.

When you delete a storage domain, the migration groups within the deleted storage domain are also deleted. Volumes and migration tasks within the deleted migration group are not deleted, however.

6-1 )

6-3 )

6-4 )

5 .

Applying Filter Conditions

If a storage domain containing a migration group is currently refreshing data, you cannot operate that migration group. You cannot delete a migration group, add or delete a volume of a migration group, or change attribute information for a migration group while the status of a migration task is Active or Standby.

Only the System Administrator and Storage Administrator can create, change, or delete a migration group, or add or delete a volume. The System Administrator, Storage Administrator, and Guests who have access privileges can reference migration groups.

You can create a migration group within a storage domain. There is no restriction on the number of migration groups you can create within a single storage domain.

For each migration group, you can specify a migration group name, description of the migration group, and a status indicating whether migration is enabled.

There are three methods for creating a migration group:

• Creating an empty migration group without any volumes before adding volumes to it.

You can even create an empty migration group that does not contain any volumes. In this case, you must add volumes after you create the migration group. See Section

• Creating a migration group by searching volumes within a storage domain.

See Section

• Creating a migration group by searching volumes within a storage tier.

7 Performing a Migration

This chapter describes performing a migration, which includes creating a migration task and then executing it.

• About Migration Tasks (section

• Migration Task Operations (section 7-2 )

• Steps for Performing a Migration (section

For more information on searching for a migration task, viewing detailed information about a migration task, and executing or deleting a migration task, see

7-1 About Migration Tasks

A migration task is the migration (movement of data from the migration source volume to the migration target volume) of each volume within a migration group.

A migration task is created by specifying the correspondence between the migration source volumes within the migration group and the migration target volumes that match the volume search result for that storage tier, as well as their options.

There is no restriction to the number of migration tasks you can create within the same storage domain.

When a storage domain that contains the operation-target storage tiers is being refreshed, you cannot operate those storage tiers.

7-1-1 Attributes of Migration Tasks

Migration tasks have the following attributes. You can check the attributes in the detailed information for a migration task.

• Task ID and a description statement about the corresponding migration task.

• A user who registers the migration task, and a user group of the user.

• Status of the migration task.

• Creation time, execution request time, and end time.

• Storage domain, migration group, and migration target storage tier.

• Total capacity of the data to be migrated.

• Progress of migration (including the progress of each volume).

When you create a migration task, it is given a task ID (TK########). The character string ######## consists of the time that the migration task was created and the serial number. The value ######## is obtained by adding the time and serial number, and then converting the result to base 36.

Creating a Migration Group

7-1-2 Status of Migration Tasks

A migration task can be in any of a number of statuses. By specifying the task ID, date, or status, you can find out whether the corresponding migration task has finished (the status of the migration task is Success, Failure, or Cancel) and its current status.

On a Web client, the status of a migration task is displayed only by an icon, or by an icon and the status enclosed in parenthesis. If the status is Failure, it might be displayed by an icon, and Failure.MigrationFailure or Failure.DataErasureFailure. For more information about icon meanings and sub-statuses, see GUI Help.

On a CLI client, you can use the GetTasks command to check the status of a migration task. For more information, refer to the HP StorageWorks XP Tiered Storage Manager CLI Reference Guide.

Table 7-1 lists the migration task status messages displayed by a CLI client and by a Web client icon.

Table 7-1 Migration Task Status Messages

Status Displayed by a CLI client Status Displayed by a Web client

Success Success Failure Failure Failure.MigrationFailure Failure.DataErasureFailure Cancel Cancel

• A migration task whose status is not Standby cannot be performed.

• When the migration task status is either Active or Standby, none of the storage domain, the storage

tier or the migration group can be deleted, nor can the attribute information be changed. Wait until the migration task status changes to Success, Failure, or Cancel, and then retry the operation.

7-2 Migration Task Operations

Migration task operations include creating and executing a migration task (described in this chapter) and deleting a migration task, searching for a migration task, canceling a migration task and referencing detailed information about a migration task (described in

You can create and execute a migration task in two ways:

• Create a migration task and then immediately issue an execution request to Tiered Storage Manager.

• Create a migration task, place it in a Standby status, and then later issue an execution request to Tiered

Storage Manager.

Figure 7-1 illustrates the process of creating and executing a migration task on the Tiered Storage Manager web and CLI clients:

Figure 7-2 illustrates the migration and the flow of operations at a Web client.

Figure 7-2 Migration and Operations at a Web client

7-3 Steps for Performing a Migration

You can perform migration that is either concurrent to migration task registration or subsequent to migration task registration. You can also change the migration target volume before the migration task is registered.

IMPORTANT: After you create a migration task, do not change the configuration of volumes in the storage

subsystem until the migration task finishes. If you do, a migration might fail or have unintended results. For example, if Remote Web Console or Device Manager changes the migration source volumes to LUSEs after a migration task is created, only some of the LDEVs in the LUSE volume are migrated, and then those LDEVs become incomplete LUSE volumes.

To perform a migration:

1. In the Navigation frame, select the Migration Groups object.

The information frame displays the List Objects-Migration Groups subwindow, as shown in below.

window (KATS62010-E or KATS62011- E)

For some volumes in the migration group, a volume that can be selected as the migration target volume does not exist in the target storage tier.

Possible causes are as follows:

• An error might have occurred

in the subsystem and an attempt to acquire the progress status has failed.

• Processing to update the

display has not started because multiple migration tasks are being performed and processing to startup or finish these tasks might be taking a long time.

• If a high load is placed on the

subsystem, migration might not progress or might fail before completion. In particular, if a volume that is being migrated is accessed, progress of the migration task might deteriorate.

Possible causes are as follows:

• There is a problem with a

volume that was selected as a migration target.

• Since Remote Web Console

For a storage tier, Tiered Storage Manager automatically selects volumes when all volumes in the storage tier satisfy all of the following conditions:

• The capacity of the target

volume is equal to the source volume.

• The emulation type of the

target volume is the same as that of the source volume.

• When a migration is

performed between a CVS volume and a normal volume, the emulation type is OPEN-V.

• The array group of the target

volume is different from that of the source volume.

• The CVS attribute (CVS or

Normal) of the target volume is the same as that of the source volume.

• The target volume is an

unused volume (except that Tiered Storage Manager always selects the primary

volume automatically). For all volumes in the migration group, prepare a storage tier that includes volumes satisfying the above conditions.

• See the message log to

check whether an error has

occurred in the subsystem. If

it has, refer to the message

to remove the cause of the

error.

• If there is a task that is

progressing among the

multiple migration tasks,

Tiered Storage Manager is

running properly.

• If migration fails, temporarily

decrease the load on the

subsystem, and then retry

the migration.

Troubleshooting

Remove the cause of the error, and then re-create the migration task. Depending on the timing of the error, some volumes may have been reserved. In this case,

Migration has finished. The LDEVs of the migration source volume and the migration target volume have been switched. Check the status of the source volume whose LDEV has been switched to the LDEV number of the target volume. If data erasure fails, the original data remains in the source volume. (For details, see Figure 12-1 Relationship

between Volumes and LDEV Numbers 1-3 How Migration Works) Therefore, perform the

following action: If the Volume to which the LDEV number of the source volume has been switched is blocked Format the relevant volume by using Remote Web Console. If the Volume to which the LDEV number of the source volume has been switched is not blocked There may be data remaining on the relevant volume. If the remaining data needs to be erased, format the volume or erase the data using the procedures below. In the explanation below logical device number 10:01 has been migrated to 20:01 (the source volume before migration has been switched to 20:01 after migration).

Situation (2)

Situation (1) The migration volume pair was created so that LDEVs other than the representative LDEV that do not meet the conditions of the migration destination storage tier would not be migrated.

The migration volume pair was created so that LDEVs that meet the conditions of the migration destination storage tier would be migrated unnecessarily.

An error occurred during migration. The details of the error are displayed in the Task Detailed Information-Task ID popup window (11-2 Viewing

Both of the following conditions exist:·

• The representative LDEV is

not included in the migration

destination storage tier.

• LDEVs other than the

representative LDEV are

included in the migration

destination storage tier.

Depending on the cause of the error, migration may be treated as a migration failure in Tiered Storage Manager or Device Manager, even though migration has finished in the storage subsystem. Therefore, you need to refresh the relevant storage domain by using Tiered Storage Manager to update the management information of Tiered Storage Manager and Device Manager to the current information. If a volume is left as reserved, it is released during the refresh. After that, view the volume information of migration tasks that have a failure status, and then, from the elements listed below, determine whether the migration task has been executed. In this case, check the following elements for all logical devices (LDEV) in the migration group:

• Array group name

• Subsystem name

If there is a logical device for which migration has not been executed, remove the cause of the error, and then create and execute the migration task again. Review the migration volume pair. If you migrate LDEVs other than the representative LDEV, first respecify the migration destination volume, and then perform migration.

Review the migration volume pair. Create a storage tier that includes the representative LDEV, and the status will change to situation (1). See the recommended action column for situation (1) and take appropriate action.

For details on the Migrate - Step 4 of 4 popup window, see 7-3 Steps for Performing a Migration
