You can use the repairsevdiskcopy command
from the command-line interface to repair the metadata on a space-efficient
virtual disk (VDisk).
The repairsevdiskcopy command
automatically detects and repairs corrupted metadata. The command
holds the VDisk 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 virtual disk copies in the configuration.
When you
issue the repairsevdiskcopy command, you
must specify the name or ID of the VDisk to be repaired as the last
entry on the command line. Once started, a repair operation cannot
be paused or cancelled; the repair can only be terminated by deleting
the copy.
Attention: Use this command only to repair
a space-efficient
VDisk that
has reported corrupt metadata.
Issue the following command
to repair the metadata on a
space-efficient
VDisk:
svctask 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 space-efficient
VDisk using
the CLI
Issue the
lsrepairsevdiskcopyprogress command
to list the repair progress for
space-efficient
VDisk copies
of the specified VDisk. If you do not specify a VDisk, the command
lists the repair progress for all space-efficient copies in the cluster.
Note: Only
run this command after you run the svctask repairsevdiskcopy command,
which you must only run as required by the Directed Maintenance Procedures
or by IBM® support.
