Introduction

StorNext is data management software that enables customers to complete projects faster and confidently store more data at a lower cost. Used in the world's most demanding environments, StorNext is the standard for high performance shared workflow operations and multitier archives. StorNext consists of two components: StorNext File System (SNFS), a high performance data sharing software, and StorNext Storage Manager (SNSM), the intelligent, policy-based data mover.

About StorNext File System

Quantum StorNext User’s Guide 1

StorNext File System streamlines processes and facilitates faster job completion by enabling multiple business applications to work from a single, consolidated data set. Using SNFS, applications running on different operating systems (Windows, Linux, Solaris, HP-UX, AIX, and Mac OS X) can simultaneously access and modify files on a common, high-speed SAN storage pool.

This centralized storage solution eliminates slow LAN-based file transfers between workstations and dramatically reduces delays caused by single-server failures. In high availability (HA) configurations, a redundant server is available to access files and pick up processing requirements of a failed system, and carry on processing.

Chapter 1: Introduction

About StorNext Storage Manager

About Distributed LAN Clients

StorNext Storage Manager enhances the StorNext solution by

reducing the cost of long term data retention, without sacrificing accessibility. SNSM sits on top of SNFS and utilizes intelligent data movers to transparently locate data on multiple tiers of storage. This enables customers to store more files at a lower cost, without having to reconfigure applications to retrieve data from disparate locations. Instead, applications continue to access files normally and SNSM automatically handles data access – regardless of where the file resides. As data movement occurs, SNSM also performs a variety of data protection services to guarantee that data is safeguarded both on site and off site.

StorNext supports SAN client, a distributed LAN client does not connect directly to StorNext via fibre channel or iSCSI, but rather across a LAN through a gateway system called a server is itself a directly connected StorNext client, but it processes requests from distributed LAN clients in addition to running applications.

Any number of distributed LAN clients can connect to multiple distributed LAN servers. StorNext File System supports Distributed LAN client environments in excess of 1000 clients.

distributed LAN clients

distributed LAN server

. Unlike a traditional StorNext

. The distributed LAN

Besides the obvious cost-savings benefit of using distributed LAN clients, there will be performance improvements as well.

Distributed LAN clients must be licensed in the same way as StorNext SAN clients. When you request your permanent StorNext license, you will need to specify the number of distributed LAN clients you plan to use. Naturally, you can always purchase additional distributed LAN client licenses as your needs expand. For more information about StorNext licensing, see

StorNext provides distributed LAN client information via the status monitors on the StorNext home page. More detailed information is available through the Clients Report and the Distributed LAN Client Performance Report. For more information about StorNext reports, see

StorNext Reports on page 205.

Before you can fully use distributed LAN clients, you must first configure a distributed LAN server and distributed LAN clients as described in the

The Configuration Wizard

StorNext includes a Configuration Wizard that guides you through the process of setting up your StorNext system. The wizard includes tasks you would typically perform when you are first configuring your system.

The Configuration Wizard appears automatically when you launch StorNext for the first time. As you complete tasks, click Next to proceed to the next configuration task, or click Back to return to the previous task. Some tasks allow you to skip the task for configuration at a later time. These tasks have a Next/Skip button instead of a Next button.

You can display the Configuration Wizard at any time by selecting Configuration Wizard from the StorNext Configuration menu. If you have completed all of the tasks, each task will be marked as Complete. If you have not completed all tasks, the ones you finished will be marked Complete and the wizard will be ready for you to begin the next uncompleted task.

You can perform any of the Configuration Wizard’s tasks separately rather than through the wizard. Each of these tasks is selectable from the StorNext Configuration menu.

Following are the setup and configuration tasks the Configuration Wizard allows you to complete:

• Step 1: Welcome: View disks and libraries currently available for StorNext usage

• Step 2: Licenses: Enter StorNext License Information

Quantum StorNext User’s Guide 17

Chapter 3: The Configuration Wizard Step 1: Welcome

Chapter 3: The Configuration Wizard

Step 2: Licenses

Use the Enter License wizard to enter license strings for the StorNext products you have purchased. You must have a license to configure or use StorNext products or features.

If the license.dat file does not contain permanent licenses, StorNext produces an auto-generated license with an expiration date for all StorNext products and features except Deduplication. In some cases Quantum may provide evaluation licenses for features. Evaluation licenses also have a fixed expiration date.

Beyond the evaluation period, you must have a permanent license to configure or use StorNext features.

Here is a list of StorNext licenses:

• File System: A File System license enables you to create and modify StorNext-supported file systems.

• LAN Client: You must have a Distributed LAN Client license for each LAN client you use with StorNext (in addition to any SAN clients).

Quantum StorNext User’s Guide 19

Chapter 3: The Configuration Wizard Step 2: Licenses

• Storage Manager: A Storage Manager license provides full access to StorNext's Storage Manager features that are not licensed separately.

• Replication: A Replication license is required if you want to use StorNext's Data Replication feature.

• Deduplication: A Deduplication license is required if you want to use StorNext’s Data Deduplication (blockpool) feature.

• Vaulting: A Vaulting license provides the ability to move seldomused media to a manual archive vault, freeing room for media in the managed archives.

• Storage Disk: You must have a Storage Disk license to be able to configure and use StorNext storage disks.

• Checksum: A Checksum license enables you to verify data integrity by ensuring that the checksum created when data was stored matches the checksum upon data retrieval.

• Distributed Data Mover (DDM): A license is required for using DDM if you plan to use additional machines besides the primary server to distribute data streams.

• Failover (HA): A Failover (High Availability) license is required if you plan to use StorNext's HA failover features.

• Maintenance: A Maintenance license verifies that your site has purchased StorNext upgrade licenses, and is required for StorNext upgrades. It is also used at run time to verify the revision number in the software matches what was purchased.

To obtain permanent product/feature licenses, you must contact the Quantum Technical Assistance Center at

licenses@Quantum.com and

give them the following information:

• The serial number from your product CD or box.

• A list of the products/features you wish to license

• The number of StorNext SAN clients and distributed LAN clients you want to support, as well as capacity.

• The StorNext server identification number. You can find this number on the Configuration Wizard’s Configuration > Licenses screen.

After the Quantum Technical Assistance Center receives the above information, a representative will send you license strings for the products/features you specified. Enter these license strings on the

License Expiration and Limits

Each StorNext feature license has a license expiration date (shown in the Expires column) and a limit shown in the Limit column.

Following is an explanation of the limit for each feature as it pertains to licensing:

• File System: The number displayed is the maximum number of SAN clients allowed

• LAN Clients: The number displayed is the maximum number of LAN clients allowed

• Storage Manager: The number displayed is the licensed capacity for files being managed by the SNSM software.

The current used capacity for the Storage Manager feature is determined as follows: It is the sum of all managed files that have been copied to Storage Manager media. This includes tape media and also storage disk. (The capacity calculation does not include files on tape media that have been moved to a vault archive.)

Note the following about the used space that is tracked:

• The used space includes the sizes of all files stored to the media. This includes multiple copies of files, if present, as well as old versions available for recovery.

• The used space includes the size of the header information written to the media with the file. This header contains

24 Quantum StorNext User’s Guide

Chapter 3: The Configuration Wizard

Step 2: Licenses

information used to verify file information at retrieve time, etcetera.

• If compression is enabled, the used space is determined by the native size of the files and not the compressed size.

• For tape media, the used space includes “dead space” for files that have been removed or modified, and for which fsclean has been run to clean up knowledge of the file in the Storage Manager database.

Note: The capacity for storage disks does not include “dead

space” but does include

all

data on the file system where the storage disk has been configured, not just files copied to the file system by the Storage Manager. To maximize the licensed Storage Manager capacity, the storage disk file systems should be restricted to Storage Manager data only. If your storage disk contains ‘user’ data you should consider moving that data to an alternate location prior to performing a StorNext upgrade.

If you are unsure about the location of the Storage Manager data on a file system run the command fsdiskcfg with no arguments. This command produces a report on the configured storage disks and the location of the managed data on each file system. The ‘Path’ column in the command output indicates the directory containing the managed data.

• Replication: Unlimited

• Deduplication: The number displayed is the size of the blockpool. The capacity is tracked to the nearest terabyte.

• Vaulting: Unlimited

• Storage Disk: Unlimited

• Checksum: Unlimited

• Distributed Data Mover (DDM): The number displayed is the maximum number of clients that can be used to run mover processes.

• Failover (HA): Unlimited

Quantum StorNext User’s Guide 25

Chapter 3: The Configuration Wizard Step 2: Licenses

• Maintenance: The number displayed is the release number for the StorNext software.

Determining License Capacity

The numbers displayed on the StorNext License screen represent

licensed capacity

actual capacity for the File System, LAN Clients, Deduplication, Replication, Failover and Maintenance licenses by running the following command from the command line:

# snlicense <license type>

When running this command, do not use capital letters or include the angled brackets around the license type.

To obtain capacities for the Storage Manager, Vaulting, Storage Disk, Checksum, DDM and Maintenance features, run the following command from the command line:

# sntsm -l <feature name>

Note that character after the dash in the preceding command is the letter L, not the numeral 1. As before, when running this command do not use capital letters or include the angled brackets around the feature name.

, not necessarily

actual capacity

. You can determine the

For more information, see the man pages for both of these commands.

Updating Licenses You will need to update a license if the license expires or if your

configuration changes (for example, if you add additional clients or increase capacity.)

To update a license, select the desired product/feature and then click Enter/Update. When the Configuration > Licenses > Enter/Update screen appears, copy the license string you received from Quantum into the [License/Feature Name] License field, and then click Apply.

Licensing and Upgrades The new licensing implementation affects StorNext upgrades, both for

release 4.0 and future releases. Be aware of the following upgraderelated implications and plan accordingly:

26 Quantum StorNext User’s Guide

Chapter 3: The Configuration Wizard

Step 2: Licenses

• A non-expired Maintenance license is required to perform a StorNext upgrade. This means you must contact Quantum Technical Support for a Maintenance license before you can upgrade to StorNext 4.0.

• The Maintenance license provided by Quantum Technical Support must be put into place prior to the upgrade, or you will not be allowed to proceed with the upgrade. This step is done by manually editing the license.dat file because the StorNext GUI has not been installed and therefore you cannot enter licenses through the GUI. This applies to upgrades to StorNext 4.0 and also to future upgrades.

• For future upgrades, for any StorNext feature or component currently in use, you must have a license in place prior to the upgrade. Otherwise, you will not be allowed to proceed with the upgrade.

• For future upgrades, after an upgrade you will still be allowed to run StorNext if the Maintenance license expires. However, no future upgrades will be allowed.

• The Maintenance license must remain in place even after expiration to allow the StorNext software to run, because it indicates which version of the software was purchased.

• If you are ready to upgrade and then notice that the Storage Manager capacity has been exceeded, you can follow the procedure below to free up capacity to bring it under the licensed value. These steps will clean up “dead space” on tape media, and do not apply to storage disks.

1 Run the fsmedcopy command with no arguments. Running

command generates a report of media and wasted space. The report looks similar to this:

% fsmedcopy

---------------------------------------------------- Media Fragmentation Report Thu Feb 4

15:18:14 2010

Media ID Fill Level Wasted Space

---------------------------------------------------- 000099 10.00 0.00 000098 30.00 5.00 000096 70.99 44.98 000099 0.12 99.65

Quantum StorNext User’s Guide 27

Chapter 3: The Configuration Wizard Step 3: Name Servers

The “Fill Level” column shows how full the media is. The “Wasted Space” column indicates how much of the used space is wasted, NOT the percentage of the entire tape.

Media with high percentages for both values (such as media 000096 in the example) are good candidates for eliminating dead space.

2 For each media you identify as having significant dead space,

run this command:

% fsmedcopy -r <mediaid>

Note: On a large system, the fsmedcopy report can take a

long time to complete. If your site is dynamic (that is, it has a lot of file removes and updates,) you can skip step 1 and just pick media you know are full, and then run the command fsmedcopy -r against those media.

Manually Editing the license.dat File

If you choose to manually edit the license.dat file instead of using the StorNext GUI, your manual changes will not be reflected in the StorNext GUI until you restart services by running #service cvfs restart from the command line. Alternatively, you can restart services using the StorNext GUI as described in

System Control on page 165.

Step 3: Name Servers

This screen enables you to manage machines acting as File System name servers. These machine names are copied into the StorNext fsnameservers file, which specifies machines serving as File System Name Server coordinator(s). The File System Name Server coordinator is a critical component of the StorNext File System Services (FSS).

A principal function of the coordinator is to manage failover voting in a high-availability configuration. Therefore, it is critical to select highly reliable systems as coordinators. Redundancy is provided by listing multiple machine entries in the fsnameservers file, one entry per line.

28 Quantum StorNext User’s Guide

Figure 8 Name Servers Screen

Chapter 3: The Configuration Wizard

Step 3: Name Servers

The first machine listed is the primary coordinator and any subsequent machines listed serve as backup coordinators. To create redundancy, it is recommended that you list two machines. Typically, the selected systems are also configured for FSM services, but this is not a requirement.

If the fsnameservers file does not exist, then the file system operates as a local file system, requiring both a client and a server. The file system will not communicate with any other StorNext File System product on the network, thus eliminating the sharing of the FSS over the SAN.

1 When the Configuration Wizard is displayed, choose Name Servers

on the left side of the screen. (Alternatively, choose Name Servers from the Configuration menu.) The Configuration > Name Servers screen appears. (If name servers were previously created, a list of those IP addresses appears on the Name Servers screen.)

then click Delete. Finalize the deletion by clicking Apply.

Caution: This delete function does not provide a confirmation

message before completing the deletion, so be absolutely certain you want to delete a name server before clicking

Delete.

Step 4: File Systems

Chapter 3: The Configuration Wizard

Step 5: Storage Destinations

Storage Disk Overview Storage disks are external devices on UNIX-based file systems that can

be used for long term data storage. Storage disks function and operate the same way as physical tape media.

When a storage disk is configured, the StorNext Storage Manager moves data to storage disks for long-term retention in addition to, or instead of tape. This enables users to leverage the specialized third-party functionality of appliances or store small files that might take longer to retrieve from tape. Many users will still use tape for long-term storage and vaulting, but storage disk can be used to create tape-free archives.

Here are a few differences storage disks have over tape media, aside from the obvious cost-saving benefit:

• A storage disk either belongs to no policy class, or belongs to a single policy class

• A storage disk can store file copies only with the same copy ID.

Note: Before you create a storage disk, the disks you plan to use must

reside in an existing, mounted file system.

After you create a storage disk, observe the following usage recommendations:

• If your file system includes storage disks, avoid using that file system for any data other than storage disk stored data.

• Use complete and physically dedicated file systems (snfs, local, NFS, or other,) for storage disk data, not shared file systems or file systems with linked directories.

• If your file system includes storage disks and you accidentally fill it with unrelated user data (i.e., non-storage disk data,) call the Quantum Technical Assistance Center and ask for a procedure to clean up and transcribe data.

The following procedures describe how to view, edit and delete storage disks. The procedure for adding a storage disk is identical to entering one through the StorNext Configuration Wizard as described in

Quantum StorNext User’s Guide 47

Chapter 3: The Configuration Wizard Step 6: Storage Policies

Figure 22 Configuration > Storage Destinations > Replication / Deduplication Screen (Blockpool)

Step 6: Storage Policies

A storage policy defines how files will be managed in a directory and subdirectories.

These are the available storage policy settings:

• Number of copies to create

• Media type to use when storing data

• Amount of time to store data after data is modified

• If disk-to-disk relocation is enabled, the amount of time (in days) before relocating a file

• Amount of time before truncating a file after a file is modified

Storage policies can be related to one or more directories. In this situation, all files in that directory and sub-directories are governed by the storage policy. The connection between a storage policy and a directory is called the relation point.

48 Quantum StorNext User’s Guide

Chapter 3: The Configuration Wizard

Step 6: Storage Policies

Here are some examples of storage policy usage:

• A directory in which to store backups every night is created. This directory is seldom accessed after the files are copied over. A storage policy could be set up to create two tape copies of the files, store one copy of the files to AIT media after residing on disk for 10 minutes, and then truncate the other set of files immediately after storing the other set to tape in order to free up disk space. This policy can be associated with a directory such as: /sandsm/dsm1/ backup.

• A directory has been created to store all documents that are accessed frequently, and if truncated, need to be retrieved quickly. The in this case could be set up to create a single tape copy, store the files to LTO media 15 minutes after being on disk, and then truncate after 60 days of non-use. This policy can be associated with a directory such as: /sandsm/dsm1/docs.

Chapter 4: File System Tasks Label Disks

Label Disks

Each drive used by StorNext must be labeled. (A new drive must be labeled only one time.) You can label a drive from any StorNext server or client that has a fibre channel (FC) connection to the drive.

There are two types of label:

• EFI labels are required if you plan to create LUNs that are larger than 2TB. (For Solaris, EFI labels are also required for LUNs with a raw capacity greater than 1TB.) EFI labels will not work with the IRIX operating system.

• VTOC labels were used for all operating systems in previous StorNext and Xsan releases, and are still required for the SGI IRIX operating system, Solaris releases prior to Solaris 10 Update 2, and LUNs less than 1TB.

Labeling a Device Follow this procedure to label any new or unused devices, or relabel a

device that has been unlabeled.

Caution: Labeling a disk device may result in a complete loss of data

on that disk device.

1 Choose Label Disks from the Tools > File Systems menu. The To ol s

2 Select the disk devices to which you want to apply labels. (Click All

to select all available disks.) If a disk device already has a label, continuing with this procedure overwrites the existing label.

Caution: Overwriting or renaming a disk device label may result

in a complete loss of data on that disk device.

3 Specify the label type by choosing EFI or VTOC.

4 Enter a label name in the text field to the right of the EFI and VTOC

buttons.

5 Click Label.

6 When the confirmation message appears, verify that the disk you

are labeling is empty, and then click OK to proceed. (Click Cancel to abort without labelling the disk.)

Note: If you later unlabel a device and then decide to make the

unlabeled device usable by the StorNext File System, you must first relabel the device. The relabeling process is identical to labeling initially.

Caution: When you unlabel a device, all data on that device will be

lost. Additionally, the unlabeled device will no longer be used by the file system until it is relabeled.

Check File System

Before you perform either File System Expansion or Migration, you must first perform a check on the file system you plan to use for these features. This operation could take a significant amount of time depending on the size of the file system, so plan accordingly.

Also, this operation could consume a significant amount of space on the local file system. For example, for large file systems you should allow at least 20GB of free space on the local file system for temporary files.

Use the following procedure to perform a file system check.

66 Quantum StorNext User’s Guide

Figure 36 Check File System Screen

Chapter 4: File System Tasks

Check File System

1 Choose Check File System from the Tools > File Systems menu.

The Tools > Check > [file system name] screen appears.

2 At the Temp File Directory field, enter a new directory if the

specified directory does not have enough space to perform the check. (The checking process on large file systems can take hundreds of megabytes or more of local system disk space for working files.)

3 Select the file system you want to check. (Only file systems eligible

for File System Expansion or Migration are shown.)

4 Click Check to begin checking the selected file system. Current

progress and other details about the checking process appear at the bottom of the screen.

Note: If the file system you select is currently started and mounted,

the check will be automatically performed in read-only mode. In read-only mode on a live file system (started and mounted,) you could receive false errors.

is used to steer the allocation of a file’s data onto a set of

means a stripe group has both an affinity and the exclusive

Chapter 4: File System Tasks Affinities

Affinities for stripe groups are defined in the file system configuration file. Although stripe groups can be created by adding one or more Affinity lines to the configuration file’s StripeGroup section, Quantum recommends using the StorNext GUI to add stripe groups. A stripe group may have multiple affinities, and an affinity may be assigned to multiple stripe groups.

Allocation Strategy • StorNext has multiple allocation strategies which can be set at the

file system level. These strategies control where a new file’s first blocks will be allocated. Affinities modify this behavior in two ways:

• A file with an affinity will be allocated only on a stripe group with matching affinity.

• A stripe group with an affinity and the exclusive attribute will be used only for allocations by files with matching affinity.

Once a file has been created, StorNext attempts to keep all of its data on the same stripe group. If there is no more space on that stripe group, data may be allocated from another stripe group. If the file has an affinity, only stripe groups with that affinity will be considered; if all stripe groups with that affinity are full, new space may not be allocated for the file, even if other stripe groups are available.

Example Use Cases Affinities can be used to segregate audio and video files onto their own

stripe groups. For example:

• Create one or more stripe groups with an AUDIO affinity and the exclusive attribute.

• Create one or more stripe groups with a VIDEO affinity and the exclusive attribute.

• Create one or more stripe groups with no affinity (for non-audio, non-video files).

• Create a directory for audio using ‘cvmkdir -k AUDIO audio’.

• Create a directory for video using ‘cvmkdir -k VIDEO video’.

Files created within the audio directory will reside only on the AUDIO stripe group. (If this stripe group fills, no more audio files can be created.)

70 Quantum StorNext User’s Guide

Chapter 4: File System Tasks

Affinities

Files created within the video directory will reside only on the VIDEO stripe group. (If this stripe group fills, no more video files can be created.)

To reserve high-speed disk for critical files:

• Create a stripe group with a FAST affinity and the exclusive attribute.

• Label the critical files or directories with the FAST affinity.

The disadvantage here is that the critical files are restricted to only using the fast disk. If the fast disk fills up, the files will not have space allocated on slow disks.

To reserve high-speed disk for critical files, but allow them to grow onto slow disks:

• Create a stripe group with a FAST affinity and the exclusive attribute.

• Create all of the critical files, pre allocating at least one block of space, with the FAST affinity. (Or move them using snfsdefrag, after ensuring they are non-empty.)

• Remove the FAST affinity from the critical files.

Because files will allocate from their existing stripe group, even if they no longer have a matching affinity, the critical files will continue to grow on the FAST stripe group. Once this stripe group is full, they can allocate space from other stripe groups, since they do not have an affinity.

This will not work if critical files may be created later, unless there is a process to move them to the FAST stripe group, or an affinity is set on the critical files by inheritance but removed after their first allocation (to allow them to grow onto non-FAST groups).

Adding a New Affinity Follow this procedure to add affinities:

1 Choose Affinities from the Tools > File Systems menu. The To o l s >

File Systems > Affinities screen appears.

Chapter 4: File System Tasks

Migrate Data

Migrating file system data refers to moving data files from a file system’s source stripe group to all the other stripe groups on the same file system, and then freeing the source stripe group so it can be removed from the file system. You can select the source stripe group only, not the destination stripe group(s). Files will be moved randomly to new stripe groups while respecting their affinity rules (if any). When migrating, make sure the source stripe group is completely empty when the process completes, because source files that are updated while the file system is running may be left behind, requiring a second iteration of the migration.

During file system migration, you indicate a file system from which to move data.

StorNext then moves all data of the same type (either data or metadata,) from the source file system to the specified destination

Quantum StorNext User’s Guide 73

Chapter 4: File System Tasks Migrate Data

stripe group. During movement the file system is left online and read/ write operations occur normally.

The time it takes to complete the migration process depends on the amount of data being moved between source file system and target stripe groups. When moving a data stripe group, the file system continues to run during the move. StorNext does not block any new read/write requests, or block updates to existing files on the source file system. All operations (including metadata operations) are handled normally, but no new writes are allowed to the source stripe group, which will be marked read-only.

Use the following procedure to perform file system migration.

1 Choose Migrate Data from the Tools > File Systems menu. The

Tools > File systems > Migrate screen appears.

2 Select the target file system from which files will be migrated.

3 Select the destination stripe group to which files will be migrated.
