This chapter describes the outlines, features, operating environment, user management function,

and operation screens for ETERNUS DX Disk storage system Web GUI (hereinafter referred to

as "GUI").

GUI is installed in controllers of the ETERNUS DX Disk storage systems, and used for perform-

ing settings and maintenance via web browser.

1.1 Outline

Use GUI to set the operating environment and check status for the ETERNUS DX Disk storage

system.

GUI can be operated from a web browser by connecting the PC via a LAN connection.

Refer to "Chapter 2 Startup and Shutdown" (page 25)

ETERNUS Web GUI User’s Guide

for details of GUI start up.

Chapter 1 Outline

1.2 Features

The features for GUI are as follows:

● Initial settings by the wizard

● Status Display

● Checking the extent of a failure

● Easy operation

The wizard provides instructions for the basic settings that are required to run the ETERNUS DX Disk storage system.

This function displays the device installation image.

If a drive failure occurs, host port, LUN group, volume, RAID group, and installation location can be referenced to determine the extent of the failure.

If a hardware failure is detected, the system administrator can receive a mail containing detected failure information.

ETERNUS Web GUI User’s Guide

Chapter 1 Outline

1.3 Operating Environment

The following PC environment is required to use GUI.

Confirmed operating environment Ver sion

Web browser Microsoft® Internet Explorer 7.0, 8.0

Mozilla Firefox™ 3.6.X

Image resolution

• 1024 x 768 or more

• 24-bit color or more is recommended

• Note the following:

- Set "Do not use proxy server" as the proxy setting

- Set page acquisition to not use the cache

When using Internet Explorer 7.0, select [Every time you start Internet Explorer].

- Enable the Java Script setting

- When Auto Reading of pages is available, enable the setting

• Furthermore, when using ETERNUSmgr with Microsoft® Internet

Explorer 7.0, note the following:

- Enable [Automatic prompting for file downloads] and [Allow websites

to open windows without address or status bars] under the Internet Options Security tab.

- Disable the [Show friendly HTTP error messages] under the Internet

Options Advanced tab.

• Furthermore, when using ETERNUSmgr with Microsoft® Internet

Explorer 8.0, note the following:

- Enable [Automatic prompting for file downloads] and [Allow websites

to open windows without address or status bars] under the Internet Options Security tab.

- Disable the SmartScreen Filter in the [Tools] menu, or disable the

SmartScreen Filter by clicking the [Safety] button, or delete the default gateway settings of the PC.

• If the PC and the ETERNUS DX Disk storage system belong to a

different network and the transfer rate setting for each network does not match, the retransmission of packets occur more frequently and the operation screen for Web GUI may take more time to display. By setting the same transfer rate for each network, the retransmission of packets can be reduced. Note the following points when setting the transfer rate:

- Set the same transfer rate for each network

- When the transfer rate for the ETERNUS DX Disk storage system is

not "Auto-negotiation", the same transfer rate must also be set for the network switches

1.4 User Management

Appropriate user management is important to ensure that security is maintained within the sys-

tem.

The user management function applies roles with multiple policies when user accounts are cre-

ated to specify the functions that are allowed for each user. For normal operation of the ETER-

NUS DX Disk storage system, apply the "Admin" default role for the system administrator and

apply the "Maintainer" default role for the maintenance engineer.

Operation mistakes and maintenance worker hours can be reduced and device security can be

improved by placing the authorized functions of system administrators in units of usage and by

only giving the minimum necessary policies to system administrators.

Refer to "Appendix A User Roles and Policies" (page 592) for details about user roles and policies.

5.2.1 Create Volume

This function creates new volumes in the existing RAID group or Thin Provisioning Pool (TPP). Standard volumes, Thin Provisioning Volumes (TPV), Snap Data Volumes (SDV), and Snap Data Pool Volumes (SDPV) can be created. Volumes are formatted automatically when they are created. Standard, TPV, and SDV can be accessed from the host when host affinity is set after volume creation. Note that SDPVs can be used after volume formatting.

• If a Thin Provisioning license is not registered, TPV cannot be created.

• If an Advanced Copy license is not registered, SDV and SDPV cannot

be created.

• When encryption mode is disabled, volumes encrypted by CM cannot

be created.

• The following shows the maximum number of volumes that can be

created for each model.

- ETERNUS DX80 S2: 2048

- ETERNUS DX90 S2: 4096

- ETERNUS DX410 S2/DX440 S2: 16384

• The following shows the maximum capacity of TPV that can be created

for each model.

- ETERNUS DX80 S2/DX90 S2: 128TB

- ETERNUS DX410 S2: 384TB

- ETERNUS DX440 S2: 768TB

• The following shows the conditions for creating SDPVs.

- The volume capacity must be 2TB or less

- The volume capacity must be a multiple of SDPE capacity (1GB/

2GB/4GB).

• When creating an SDV, the capacity setting is not required. 24 (MB) +

0.1% of the copy source volume capacity is automatically secured in the ETERNUS DX Disk storage system. "24MB" is the smallest volume capacity. 0.1% of the copy source volume is the capacity that is used for the controlling information area in the SDV. When using SnapOPC or SnapOPC+, make sure to create an SDV and SDPVs. An SDPV is a volume that configures an SDP. The SDP allocates free space when SDV capacity is insufficient.

• The maximum number of volumes that can be created is reduced in the

following conditions:

- When TPVs exist in the ETERNUS DX Disk storage system

- When concatenated volumes exist in the ETERNUS DX Disk storage

This function formats the selected volume. The data stored in the volume will be deleted by formatting.

• Formatting newly created volumes is not required since these volumes

are formatted automatically.

• There is a limit to the capacity of volumes that can be formatted

concurrently. If formatting fails, wait until the current format process is complete, and then format the volumes that failed to be formatted.

• When formatting a TPV, the physical allocating area that is used by the

target TPV is released.

• This function cannot be used under the following conditions:

- When a RAID group diagnosis is being performed in the ETERNUS

DX Disk storage system

- When a disk diagnosis is being performed in the ETERNUS DX Disk

storage system

- When pinned data exists in the ETERNUS DX Disk storage system

• The following volumes cannot be formatted:

- Volumes for which "Status" is "Broken", "Data Lost", "Not

Supported", or "Not Ready"

- Volumes undergoing RAID migration

- A copy source volume or a copy destination volume of an Advanced

Copy (local/remote) that is being performed

- Volumes registered in a RAID group undergoing Logical Device

Expansion (LDE)

The procedure to format a volume is as follows:

1 Select the volume to be formatted (multiple selections can be made) and click

[Format] in [Action].

5.2.7 Start RAID Migration

RAID migration (hereinafter also referred to as migration) moves an existing volume in a RAID group or TPP to a free space in another RAID group or TPP. After migration is complete, the migration source volume is automatically deleted. Migration provides the following features:

• Load balancing of host access.

• Volume capacity expansion is available when migrating volumes (only when the volume type

is "Standard")

• The RAID level of the volume can be changed.

• Because creation and format of new volumes and host interface establishment are

automatically performed, users are allowed to access the data anytime without being affected by the migration.

Migration type

The combinations of volume types (migration source volume → migration destination volume) that can be migrated are as follows:

• Standard → Standard

• Standard → TPV (*1)

• TPV → Standard (*2)

• TPV → TPV

*1: When migration from a "Standard" volume to a "TPV" volume is performed, 100% of the logical

capacity of the Standard volume is allocated as the physical capacity for the TPV. When the TPV capacity is expanded by using the procedure in "5.2.6 Expand Thin Provisioning Volume" (page

84) after migration is complete, the expanded area is physically allocated according to the capacity

that is used by the "Thin Provisioning Pool" function.

*2: When migration from a "TPV" volume to a "Standard" volume is performed, 100% of the logical

capacity of the TPV is allocated as the logical capacity (the allocated physical capacity) of the Standard volume.

Requirements for a migration source volume:

• The "Type" is "Standard" or "TPV"

• The "Status" is "Available"

• A format is not being performed (only when the volume type is "Standard")

• Migration is not being performed (the target volume is not used as a migration source or a

migration destination)

• The migration source volume is not an Advanced Copy (cascade copy) destination

• TPV balancing is not being performed

• LDE is not being performed for the RAID group to which the target volume belongs

• Encryption is not being performed for the target volume

Requirements for a migration destination RAID group:

• The maximum number of volumes are not set in the destination RAID group

Migration creates new volumes. The maximum number of volumes that can be created depends on the ETERNUS DX Disk storage system model.

5.2.16 Modify Cache Parameters

This function changes the cache parameters of each volume. Device performance varies depending on the cache hit ratio. The cache hit ratio can be improved by detecting the sequentiality for a Read/Write request from the host and reading continuous data in advance. The characteristics of Read/Write requests from the host depends on the system. Device performance may improve by specifying a cache parameter that is suitable for the system that is being used.

ETERNUS Web GUI User’s Guide

Chapter 5 Volume Management

Procedure

5.2 Functions in the Action Area for Volume

The following parameters can be specified:

• Prefetch Limit (PL)

Specify the value to calculate the amount of data that is to be read from the disk in advance (amount of data to prefetch from the disk) when the cache detects the sequentiality of data access.

• Force Prefetch (FP)

Specify whether to perform prefetch even if the sequentiality of data access is not detected.

• Multi Writeback Count (MWC)

Specify the number of processes that can be written back at the same time.

The procedure to modify cache parameters is as follows:

• The same cache parameter can be applied for multiple volumes in a

single operation.

• Cache parameters cannot be specified for TPVs.

1 Select which volume to change the cache parameters for (multiple selections

can be made) and click [Modify Cache Parameters] in [Action].

2 Change the cache parameters and click the [Modify] button.

• Prefetch Limit (PL)

Specify the Prefetch Limit of the volume between 0 and 64. If "0" is specified for the "Prefetch Limit (PL)", data prefetch is not performed. When a large "Prefetch Limit" value is specified, the amount of data that is read from a disk for a single read process is increased. As a result, the number of times that data needs to be read (Staging) from the disk is reduced. However, the amount of data that is read from the disk for a single read process increases and requested data may not be read before the next read or write request from the host is issued. In this case, the waiting time for Staging may increase.

• Force Prefetch Mode (FP)

Select whether to enable or disable the Force Prefetch Mode to forcibly read to the cache. This setting is required to improve the sequential read access performance. To enable this mode, select "ON". To disable this mode, select "OFF". When a number of sequential accesses are performed for one volume, the ETERNUS DX Disk storage system may determine that random accesses have occurred. By selecting "ON" for "Force Prefetch Mode", prefetching is forcibly performed in such a case. However, for random read access, unnecessary data is read from the disk and random read access performance may be reduced.

• Multi Writeback Count (MWC)

Specify the Multi Writeback Count. The Multi Writeback Count cannot be specified for volumes that are concatenated by the LUN concatenation function. When specifying a larger "Multi Writeback Count" value, sequential write access performance is improved. Note that this is not effective when a number of random write accesses occur. Depending on the ratio of read access and write access, read access performance may be degraded.
