Creating and Administering Plexes
Moving Plexes
Chapter 6 221
As when returning an OFFLINE plex to ACTIVE, this command
starts to recover the contents of the plex and, after the revive is
complete, sets the plex utility state to ACTIVE.
• If the volume is not in use (not ENABLED), use the following
command to re-enable the plex for use:
# vxmend on plex
For example, to re-enable a plex named vol01-02, enter:
# vxmend on vol01-02
In this case, the state of vol01-02 is set to STALE. When the volume
is next started, the data on the plex is revived from another plex, and
incorporated into the volume with its state set to ACTIVE.
If the vxinfo command shows that the volume is unstartable (see
“Listing Unstartable Volumes” in the section “Recovery from
Hardware Failure” in the VERITAS Volume Manager
Troubleshooting Guide), set one of the plexes to CLEAN using the
following command:
# vxmend fix clean plex
Start the volume using the following command:
# vxvol start volume
Moving Plexes
Moving a plex copies the data content from the original plex onto a new
plex. To move a plex, use the following command:
# vxplex mv original_plex new_plex
For a move task to be successful, the following criteria must be met:
• The old plex must be an active part of an active (ENABLED) volume.
• The new plex must be at least the same size or larger than the old
plex.
• The new plex must not be associated with another volume.
The size of the plex has several implications:
