SYMPTOMS
After you upgrade Persistent Storage Manager (PSM) from version 2.1 to version 2.2, and while you are running Veritas Volume Manager, you cannot take new PSM snapshots. Additionally, existing snapshots may be inaccessible.



CAUSE
This problem is caused by the way that PSM scans the unique ID name that is returned from the disk:
 * In PSM 2.1, the unique ID name was truncated at 16 characters.
 * In PSM 2.2, the whole 64-character limit is checked.
