6.2.2 HP IBRIX 9000 Storage Release Notes (AW549-96061, January 2013)

Implementation changes in the 6.2.1 release
The following implementation changes occurred with hardware monitoring:
• During an upgrade, user must now run the Firmware Management Tool and perform a set of
manual steps to update the firmware.
• All of the logical (volumes) and physical (controllers, ports, drive enclosures, drives, etc.) objects
that are under the control of a storage controller or pair of storage controllers are grouped together
within a new logical STORAGE_CLUSTER component in the storage health report to describe their
relationship in the storage topology.
• On the IBRIX 9320, Storage platform the HA_STORAGE health monitoring category has been
replaced with the new STORAGE_CLUSTER category for monitoring couplet visible storage. The
HA_STORAGE category is still supported but is being deprecated in the next release.
• A subset of all visible storage clusters can be monitored by specifying a list of storage cluster
UUIDs on the hpspmon command line. Prior to this change all storage clusters would have been
monitored.
File systems are created in 64–mode by default
Prior to IBRIX 6.1, file systems were created by default with 32-bit compatibility mode enabled. Starting
in 6.1 the default behavior has changed and compatibility mode is now disabled. IBRIX creates file
systems in 64-bit mode unless you changed the compatibility mode when creating the file
system. However, if the original file system was created with 32-bit compatibility mode enabled and
you later upgrade to 6.1 or later and then extend the IBRIX file system, new segments will be formatted
into the file system as 64-bit mode segments.
The following output shows the relevant portion of the output from the ibrix_fs -f fsname -i,
indicating how newer segments (37,38,39) appear on a file system originally created with compatibility
mode enabled.
NOTE: The 9th column (“FFREE”) which is your total available inode count per segment for the
original segments 66 Million per segment and that of the newer 64 bit segments of 1 billion per
segment. This segment mix and inode count does not negatively affect the operation of your file system
nor any applications.
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 IBRIX 9000 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 IBRIX 9000
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, IBRIX
9000 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,
