6.2.3 HP StoreAll Storage Release Notes (update)

Software snapshots
Upgrading pre-6.0 file systems for snapshots
To accommodate software snapshots, the inode format was changed in the 6.0 release. Consequently,
files used for snapshots must either be created on StoreAll OS software 6.0 or later, or the pre-6.0 file
system containing the files must be upgraded for snapshots. To upgrade a file system, use the
upgrade60 utility. For more information about the utility, see “upgrade60” in the HP StoreAll Storage
CLI Reference Guide.
IMPORTANT: This tool requires exclusive access to the file system and implies down time, as the file
system must be unmounted before the upgrade.
Restrictions for rename options
For file systems that were created in a release earlier than 6.0 but have not been upgraded, StoreAll
OS software can preserve all name space data in snapshots but cannot preserve file data for objects
(files). To help prevent “hybrid snap trees,” in which a snap tree contains objects with the old format,
restrictions have been implemented on rename operations. The following restrictions apply to hybrid
file systems:
• Only directories created in version 6.0 or later can become snap tree roots.
• If the old directory is not in a snap tree and the new directory is in a snap tree, rename is allowed
only if the object being renamed is snapable (that is, it has the new inode format).
The following restrictions apply to both hybrid file systems and pure 6.x file systems:
• A snap tree root cannot be renamed. Also, the path to a snap tree root cannot be changed.
• Rename is allowed when neither the old directory or the new directory are in snap trees.
• Rename is allowed when the old directory and the new directory are in the same snap tree.
Rename is not allowed when the directories are in different snap trees.
These restrictions are intended to prevent hybrid snap trees containing files with the old format. However,
hybrid snap trees can still occur when a directory having the new format is populated, using rename,
with old format objects and that directory is then made into a snap tree root or is renamed into a snap
tree. The StoreAll OS software does not prevent this situation because it could take a prohibitively
long amount of time to perform a complete scan for old objects in the sub tree being moved if the new
sub tree was sufficiently large.
Fixes
Fixes in the 6.2.3 release
• The firmware bundle includes new firmware version 1.40 for the X9720 storage controllers
(ExDS9100cc). Version 1.40 contains critical fixes and is a mandatory upgrade. After updating
the storage controllers to version 1.40, it may take 10-12 minutes for the storage controllers to
complete a reset and restart with the new firmware. During this time, issuing the command
hpsp_fmt --flashrec for the storage_ctlr component might report missing devices. Users
should wait until both controllers restart (with the new firmware) before performing any other
operations on these controllers.
