6.2 HP IBRIX 9300/9320 Storage Administrator Guide (AW549-96049, December 2012)

The new owner of the segment must be able to see the same storage as the original owner. The
Change Segment Owner dialog box lists the servers that can see the segment you selected. Select
one of these servers to be the new owner.
The Summary dialog box shows the segment migration you specified. Click Back to make any
changes, or click Finish to complete the operation.
To migrate ownership of segments from the CLI, use the following commands.
Migrate ownership of specific segments:
ibrix_fs -m -f FSNAME -s LVLIST -h HOSTNAME [-M] [-F] [-N]
To force the migration, include -M. To skip the source host update during the migration, include
-F. To skip server health checks, include -N.
The following command migrates ownership of segments ilv2 and ilv3 in file system ifs1 to
server2:
ibrix_fs -m -f ifs1 -s ilv2,ilv3 -h server2
Migrate ownership of all segments owned by specific servers:
ibrix_fs -m -f FSNAME -H HOSTNAME1,HOSTNAME2 [-M] [-F] [-N]
For example, to migrate ownership of all segments in file system ifs1 from server1 to server2:
ibrix_fs -m -f ifs1 -H server1,server2
Evacuating segments and removing storage from the cluster
Before removing storage used for an IBRIX software file system, you will need to evacuate the
segments (or logical volumes) storing file system data. This procedure moves the data to other
segments in the file system and is transparent to users or applications accessing the file system.
When evacuating a segment, you should be aware of the following restrictions:
• While the evacuation task is running, the system prevents other tasks from running on the file
system. Similarly, if another task is running on the file system, the evacuation task cannot be
scheduled until the first task is complete.
• The file system must be quiescent (no active I/O while a segment is being evacuated). Running
this utility while the file system is active may result in data inconsistency or loss.
To evacuate a segment, complete the following steps:
