6.0 HP X9720 Network Storage System Administrator Guide (AW549-96034, December 2011)

1. Identify the segment residing on the physical volume to be removed. Select Storage from the
Navigator on the management console GUI. Note the file system and segment number on the
affected physical volume.
2. Locate other segments on the file system that can accommodate the data being evacuated
from the affected segment. Select the file system on the management console GUI and then
select Segments from the lower Navigator. If segments with adequate space are not available,
add segments to the file system.
3. If quotas are enabled on the file system, disable them:
ibrix_fs -q -D -f FSNAME
4. Evacuate the segment. Select the file system on the management console GUI and then select
Active Tasks > Rebalancer from the lower Navigator. Select New on the Task Summary page.
When the Start Rebalancing dialog box appears, open the Advanced tab. Check Evacuate
source segments and note the cautions that are displayed. In the Source Segments column,
select the segments to evacuate, and in the Destination Segments column, select the segments
to receive the data. (If you do not select destination segments, the data is spread among the
available segments.)
The Task Summary window displays the progress of the rebalance operation and reports any
errors. If you need to stop the operation, click Stop.
5. When the rebalance operation completes, remove the storage from the cluster:
ibrix_fs -B -f FSNAME -n BADSEGNUMLIST
The segment number associated with the storage is not reused.
6. If quotas were disabled on the file system, unmount the file system and then re-enable quotas
using the following command:
ibrix_fs -q -E -f FSNAME
Then remount the file system.
To evacuate a segment using the CLI, use the ibrix_rebalance -e command, as described
in the HP X9000 File Serving Software CLI Reference Guide.
