Update pathsFollowing are the supported update paths to S-Series platform software version 8.1.

If you choose to update your S-Series platform software version, you cannot later downgrade it to an earlier software version. For example, you cannot perform a software downgrade from V8.1 to V7.3.

Platform requirements for S-Series software version 8.1

Hardware• An S-Series HP Gen8 or G7 server or an S1500 server• Hitachi Virtual Storage Platform (VSP) G200/G400/G600 disk storage arrays,

Hitachi Unified Storage (HUS) arrays or Adaptable Modular Storage (AMS) arrays • Appropriate Ethernet or Fibre Channel switches

Software

For maximum performance the S-Series V8.1 software supports a maximum block size of 512 KB for all backup applications. HDS recommends that you set the block size to 256 KB.

NetBackup

If you are using the NetBackup application, you should set the SIZE_DATA_BUFFERS value to 262144 or lower or the backups will not work.

Refer to NetBackup documentation for details on how to configure SIZE_DATA_BUFFERS.

NetWorker

DeltaStor is optimized for at least 256-KB size blocks/tape records. HDS recommends setting the tape drives to use a 256-KB block size. Otherwise, NetWorker uses a block size based on the device type used; for example, LTO-2 is set by EMC to 64 KB, assuming that the operating system is configured for variable block size mode. Refer to the EMC NetWorker documentation for additional information.

Data Protector

If you are using the Data Protector application, the maximum that you can set the block size to is 256 KB.

Updating the S-Series platform with tape image replicationIf you are running tape image replication on your S-Series platform, it is important to place the source and the target libraries into an offline state before continuing with the software update procedure. This ensures that the source and the target systems are not running incompatible versions of the S-Series platform software while the source and the target systems are being software updated.

Tape image replication supports bidirectional replication between the following software versions:

NOTE: Data will not be replicated while the replication source and the target libraries are offline. Any data backed up to the S-Series source platform during this window will be replicated when the source and the target libraries are brought back online. Therefore, you should keep the update window as short as possible.

The HDS-recommended best practice for tape image replication upgrades is to update your target system first followed by the source system.

Performing a software update on the target system1. Make sure that all backups and restores are complete.2. Place the replication target libraries into an offline state. See “Placing a replication

target into an offline state” on page 8.3. Perform the software update. See “Updating the S-Series platform with tape image

replication” and perform a software update depending on your current S-Series software version.

4. Place the replication target into an online state. See “Placing an existing offline replication target into an online state” on page 9.

Updating the OST plug-ins to V8.1You should get the latest version of the OST Plug-ins for your media servers to be compatible with the latest S-Series software version (System > Status > OST: OST Plug-in Downloads). In fact, if you are using the OST A.I.R or Optimized Duplication features, you must update the source and destination S-Series systems on the same day so that you do not end up with a mixed software environment that will not work.

Updating OST A.I.R. replication

If you are running OST A.I.R. replication, HDS recommends that you offline all A.I.R. Disk Volume Pairs from their source prior to the software update.1. Bring the Disk Volume Pairs online after the software update.
