Failure of vxsnap make for Space-Optimized Instant
Snapshots
If a vxsnapmake 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 vxsnapmake 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.
