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 [-g diskgroup] att volume plex ...

  For example, for a plex named vol01-02 on a volume named vol01 in the disk group, mydg, use the following command:

  # vxplex -g mydg 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 [-g diskgroup] on plex

  For example, to re-enable a plex named vol01-02 in the disk group, mydg, enter:

  # vxmend -g mydg 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, set one of the plexes to CLEAN using the following command:

  # vxmend [-g diskgroup] fix clean plex

  Start the volume using the following command:

  # vxvol [-g diskgroup] start volume
