If you are performing a JFS2 snapshot based operation, it is possible that the snapshot was not large enough to contain all the changes made to the filesystem after the snapshot was created. This could cause the snapshot to become invalid thereby preventing TSM client from reading the snapshot.
The requested operation does not run.
Examine the client error log for additional messages related to this error. Try the operation again. If the problem persists, contact IBM® technical support for further assistance.
If you are performing a JFS2 snapshot based operation, please use the default snapshotcachesize of 100% and ensure that the volume group has sufficient disk space to allocate snapshots at least as large as the file system and retry the operation.
