Stopping a migration task
To stop a migration task, use the following command:
ibrix_migrator -k -t TASKID [-F]
Changing the tiering configuration with the CLI
The following restrictions apply when changing the configuration:
• You cannot modify the tiering configuration for a filesystem while an active migration task is
running.
• You cannot move segments between tiers, assign them to new tiers, or unassign them from
tiers while an active migration task is running or while any rules exist that apply to the segments.
Moving a segment to another tier
Use the following command to assign a segment to another tier:
ibrix_tier -a -f FSNAME -t TIERNAME -S SEGLIST
Removing a segment from a tier
The following command removes segments from a tier. If you do not specify a segment list, all
segments in the file system are unassigned.
ibrix_tier -u -f FSNAME [-S SEGLIST]
The following example removes segments 3 and 4 from their current tier assignment:
[root@ibrix01a ~]# ibrix_tier -u -f ifs1 -S 3,4
Deleting a tier
Before deleting a tier, take these steps:
• Delete all policy rules defined for the tier.
• Allow any active tiering jobs to complete.
To unassign all segments and delete the tier, use the following command:
ibrix_tier -d -f FSNAME -t TIERNAME
