Message OP0121
Mount of logical volume xxxxxx failed because physical
volume yyyyyy is inaccessible. (rc=rrrr) (VTS z)
Probable Cause
To satisfy a logical volume mount request, the logical
volume must be recalled from a physical volume. The
mount of the physical volume failed because it is not
accessible by the robotics of the library. The two most
likely reasons for the volume to be inaccessible are that
the volume is loaded in a drive that has failed or is in a
gripper that has failed.
Note: The reason code is not useful to the operator;
however, the service representative can use the reason
code to help determine the cause of the failure.
Record the reason code, rrrr. See the “Problem
Determination Using Search Database for Volumes” on
page 456 and follow the instructions in the “Specific
Inaccessible Volume” scenario using the physical volume
volser for your search.
Message OP0122
Mount of logical volume xxxxxx located on physical
volume yyyyyy failed. (rc=rrrr) (VTS z)
Probable Cause
To satisfy a logical volume mount request, the logical
volume must be recalled from a physical volume. The
mount of the physical volume could not be completed,
and the VTS could not determine the exact reason for the
failure. If there is a dual copy of the logical volume, the
VTS will automatically attempt to recall the volume from
the secondary physical volume.
Note: The reason code is not useful to the operator;
however, the service representative can use the reason
code to help determine the cause of the failure.
1. Record the reason code, rrrr.
2. Notify your system administrator.
3. For dual Library Manager systems containing a VTS,
this intervention may be the result of a Library
Manager switchover. When a Library Manager
switchover occurs, queued or in-progress logical
mounts are not completed. This results in the VTS
asking the Library Manager to post this intervention.
If this is the case, clear the intervention and re-drive
the mount from the host.
