6.0 HP StorageWorks X9000 File Serving Software Release Notes (TA768-96042, October 2011)

Block snapshots
The following changes have been made in this release:
• Block snapshots can now be scheduled only through the GUI. The ibrix_at command is no
longer supported.
• The names of the CLI commands have been changed. Be sure to update any scripts using these
commands.
◦ The ibrix_snap command now applies to the software snapshot feature.
◦ The ibrix_vs_snap command is now used for block snapshots. The
ibrix_snap_strategy command has been renamed ibrix_vs_snap_strategy. The
-T option and the linear strategy type are no longer supported.
NTP servers
Previously, NTP servers were configured on each file serving node and synchronized their time
individually with the external time source. In the 6.0 release, the NTP server configuration is stored in
the management console configuration. The active management console node syncs its time with the
external source. The other file serving nodes sync their time with the active management console node.
In the absence of an external time source, the local hardware clock on the active agile management
console node is used as the time source. This configuration method ensures that the time is in sync on
all cluster nodes, even in the absence of an external time source.
Quotas
The ibrix_fs_ops command has been deprecated. You can now use the ibrix_edquota command
to create, view, or delete directory tree quotas.
The ibrix_online_quotacheck command has been replaced by the ibrix_onlinequotacheck
command.
When quota limits are defined, you can now set the grace period for blocks and inodes. Previously,
the grace period was set to seven days. The grace period can be defined on the GUI or with the
ibrix_edquota command.
ibrixinit command
The ibrixinit command is used to install and uninstall X9000 Software on a file serving node. The
-tm, -ts, and -M options are no longer supported for installations of the management console software
and file serving node software. In the 6.0 release, a single ibrixinit command installs both the
agile management console software and the file serving node software. The management console is
active on the first node installed and passive on the remaining nodes.
Also, the -tm and -ts options are no longer used when uninstalling X9000 Software from a file
serving node.
There are no changes to the ibrixinit command when it is used to install or uninstall X9000
Software on a Linux X9000 client.
NOTE: If you need to uninstall only the agile management console packages from a node, retaining
the file serving software packages, use the ibrixinit -tmo option. For example, if the passive
management console is configured incorrectly on a node or has a corrupt fminstance.xml file,
run the following command to uninstall the agile management console RPMs and unregister the passive
agile management console on the node:
ibrix/ibrixinit -tmo -u
