6.1.4 HP IBRIX X9000 Storage Release Notes

◦ Monitoring CIFS services on file serving nodes. This is done with the new
ibrix_cifsmonitor command.
◦ Share-level permissions for users or groups. You can assign share-level permissions on the
GUI or with the ibrix_cifsperms command.
• Data validation enhancements:
New data retention, utilization, and validation reports.◦
◦ New autocommit feature. Files that are not changed during the Autocommit period
automatically become WORM or WORM-retained when the period expires.
◦ Data retention can now be enabled on file systems created before the 6.0 release. After
upgrading the pre-6.0 file system with the upgrade60.sh utility, run the following command
on the file system to enable data retention:
ibrix_reten_adm -u -f FSNAME
See the user guide for information about configuring data retention features.
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
showing 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 have any bad effect on the operation of your
file system nor any applications.
Implementation changes in the 6.1.1 release
• By default, file systems are now created in 64-bit mode. Note the following:
The ibrix_fs –o compat and ibrix_fs –o maxsegs commands are no longer
required or supported.
◦
◦ The same number of segments are now supported in 32-bit mode and 64-bit mode.
◦ If clients need to run 32-bit applications, you can enable 32-bit compatibility mode. This
option is applied to the file system at mount time. You can enable or disable 32-bit
compatibility mode at any time, using the Modify Filesystems Properties dialog box or the
following commands:
Enable 32-bit compatibility mode:
ibrix_fs_tune -c -e -f FSNAME
Disable 32-bit compatibility mode:
