Detaching Plexes
To temporarily detach one data plex in a mirrored volume, use the
following command:
# vxplex det plex
For example, to temporarily detach a plex named vol01-02 and place it in
maintenance mode, use the following command:
# vxplex det vol01-02
This command temporarily detaches the plex, but maintains the
association between the plex and its volume. However, the plex is not
used for I/O. A plex detached with the preceding command is recovered
at system reboot. The plex state is set to STALE, so that if a vxvol start
command is run on the appropriate volume (for example, on system
reboot), the contents of the plex is recovered and made ACTIVE.
When the plex is ready to return as an active part of its volume, follow
the procedures in the following section, “Reattaching Plexes” on page 220
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
