31Recovery from failure of instant snapshot operations
Failure of vxsnap make for break-off instant snapshots
Failure of vxsnap make for break-off instant
snapshots
If a vxsnap make operation fails during the creation of a third-mirror break-off
instant snapshot, the snapshot volume may go into the INSTSNAPTMP state.
VxVM can usually recover the snapshot volume without intervention. However,
in certain situations, this recovery may not succeed. If this happens, use the
following command to delete the snapshot volume:
# vxedit [-g diskgroup ] rm snapshot_volume
Alternatively, the snapshot volume is removed automatically when the system
is next restarted.
Failure of vxsnap make for space-optimized instant
snapshots
If a vxsnap make operation fails during the creation of a space-optimized instant
snapshot, the snapshot volume may go into the INSTSNAPTMP state. VxVM can
usually recover the snapshot volume without intervention. However, in certain
situations, this recovery may not succeed. If this happens, use the following
command to delete the snapshot volume:
# vxedit [-g diskgroup ] rm snapshot_volume
Alternatively, the snapshot volume is removed automatically when the system
is next restarted.
If the vxsnap make operation was being performed on a prepared cache object by
specifying the cache attribute, the cache object remains intact after deleting
the snapshot. If the cachesize attribute was used to specify a new cache object,
the cache object does not exist after deleting the snapshot.
Failure of vxsnap restore
If a vxsnap restore operation fails, the volume being restored may go into the
DISABLED state. Use the following command to start the volume:
# vxvol [-g diskgroup ] start volume
