AIX

There is a shared volume group connected to two AIX systems A and B on a shared storage. The shared volume group was regularly attached to the system A and in case of a system A crash, the system B should take over the shared volume group and resources on it. Resources on the shared storage: filesystems and raw devices for Informix DB spaces, were also created through HACMP.

But after some time HACMP was abandonned. With HACMP shut down, some additional filesystems and raw devices were created on the shared volume group, while it was attached to the system A. One of additionally created filesystems was "/arc" over the logical volume "arclv" on the shared volume group.

The status of the logical volume on the system B is now:

Code:

smit storage
--> System Storage Management (Physical & Logical Storage)
  --> Logical Volume Manager
    --> Logical Volumes
      --> List All Logical Volumes by Volume Group
--------
--------
arclv            ???        144   144   4    closed/syncd  N/A
--------
--------

An attempt was made to change the type of the logical volume from "???" to "jfs2", as it was on the system A. The following result was obtained:

Code:

smit storage  # on system B
--> System Storage Management (Physical & Logical Storage)
  --> Logical Volume Manager
    --> Logical Volumes
      --> Set Characteristic of a Logical Volume
        --> Change a Logical Volume

1800-022 Error exit status (1) returned by
Command_to_Classify; the output is:
"0516-306 getlvodm: Unable to find  arclv in the Device
        Configuration Database.

How to fix the logical volume to be known to system B?

cold sync of the cluster - alternatively you can export and import the VG on node b but you will still have to sync some time as the cluster will error during next startup
