Reattaching Plexes
When a disk has been repaired or replaced and is again ready for use, the
plexes must be put back online (plex state set to ACTIVE). To set the
plexes to ACTIVE, use one of the following procedures depending on the
state of the volume.
• If the volume is currently ENABLED, use the following command to
reattach the plex:
# vxplex att volume plex ...
For example, for a plex named vol01-02 on a volume named vol01,
use the following command:
# vxplex att vol01 vol01-02
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
