Identifying configuration problems using Storage Expert
Checking for non-imported disk groups (vxse_dg6)
To check for disk groups that are visible to VxVM but not imported, run rule vxse_dg6.
Importing a disk to a disk group is described in “Importing a disk group” on page 167.
Checking for initialized VM disks that are not in a disk group
(vxse_disk)
To find out whether there are any initialized disks that are not a part of any disk group, run
rule
vxse_disk. This prints out a list of disks, indicating whether they are part of a disk
group or unassociated.
For information on how to add a disk to disk group, see “Adding a disk to a disk group” on
page 164.
Checking volume redundancy (vxse_redundancy)
To check whether a volume is redundant, run rule vxse_redundancy.
This rule displays a list of volumes together with the number of mirrors that are associated
with each volume. If vxse_redundancy shows that a volume does not have an associated
mirror, your data is at risk in the event of a disk failure, and you should rectify the
situation by creating a mirror for the volume.
See “Adding a mirror to a volume” on page 263 for information on adding a mirror to a
volume.
Checking states of plexes and volumes (vxse_volplex)
To check whether your disk groups contain unused objects (such as plexes and volumes),
run rule
vxse_volplex. In particular, this rule notifies you if any of the following
conditions exist:
■ disabled plexes
■ detached plexes
■ stopped volumes
■ disabled volumes
■ disabled logs
■ failed plexes
■ volumes needing recovery
If any of these conditions exist, see the following for information on correcting the
situation:
■ To re-enable a disabled or detached plex, see “Reattaching plexes” on page 223.
■ To re-enable a stopped or disabled volume, see “Starting a volume” on page 263.
