Identifying configuration problems using Storage Expert

Checking the number of configuration copies in a disk group (vxse_dg5)

To find out whether a disk group has only a single VxVM configured disk, run rule vxse_dg5.

See “Creating and administering disk groups” on page 165.

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.

See “Importing a disk group” on page 174.

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.

See “Adding a disk to a disk group” on page 171.

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 271.

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
