vxassist Error Messages

An error message from the vxassist command indicates that the requested operation

cannot be performed. Follow the recommended course of action given below.

vxvm:vxassist: ERROR: Insufficient number of active snapshot mirrors

in snapshot_volume.

◆ Description: An attempt to snap back a speciﬁed number of snapshot mirrors to their

original volume failed.

◆ Action: Specify a number of snapshot mirrors less than or equal to the number in the

snapshot volume.

vxvm:vxassist: ERROR: Volume record id rid is not found in the

configuration.

◆ Description: An error was detected while reattaching a snapshot volume using

snapback. This happens if a volume’s record identiﬁer (rid) changes as a result of a

disk group split that moved the original volume to a new disk group. The snapshot

volume is unable to recognize the original volume because its record identiﬁer has

changed.

◆ Action: Use the following command to perform the snapback:

# vxplex [-g diskgroup] -f snapback volume plex

Snapshot volume created with these plexes will have a dco volume with

no associated dco plex.

◆ Description: An error was detected while adding a DCO object and DCO volume to a

mirrored volume. There is at least one snapshot plex already created on the volume.

Because this snapshot plex was created when no DCO was associated with the

Associated Snapshots” in the chapter “Administering Volumes” of the VERITAS
