You can use the repairsevdiskcopy command
from the command-line interface to repair the metadata on a thin-provisioned volume.
The repairsevdiskcopy command automatically
detects and repairs corrupted metadata. The command holds the volume
offline during the repair, but does not prevent the disk from being
moved between I/O groups.
If a repair operation completes successfully
and the volume was previously offline because of corrupted metadata,
the command brings the volume back online. The only limit on the number
of concurrent repair operations is the number of volume copies in
the configuration.
When you issue the repairsevdiskcopy command, you must specify the name or ID of the volume to be repaired as the last entry on the command line. Once started, a repair operation cannot be paused or canceled; the repair can only be terminated by deleting the copy.
Attention: Use this command
only to repair a thin-provisioned volume that has reported corrupt
metadata.
Issue the following command to repair
the metadata on a thin-provisioned volume:
repairsevdiskcopy vdisk8
After you issue the command, no output is displayed.
Notes:
- Because the volume is offline to the host, any I/O that is submitted
to the volume while it is being repaired fails.
- When the repair operation completes successfully, the corrupted
metadata error is marked as fixed.
- If the repair operation fails, the volume is held offline and
an error is logged.
Checking the progress of the repair of a thin-provisioned volume by using the CLI
Issue the
lsrepairsevdiskcopyprogress command to list the repair progress for thin-provisioned volume copies of the specified volume. If you do not specify a volume, the command lists the repair progress for all thin-provisioned copies in the system.
Note: Only run this command after you run the repairsevdiskcopy command, which you must only run as required by the fix procedures recommended by your support team.
