problems trying to do a cold restore

Hi, I am trying to do an ontape -r and am getting this following message on all the tapes I've tried; >>"Physical restore failed - function read archive backup failed code - 1 error 22" I'm running IDS 7.31 -FC5 for Tru64 UNIX 4.0f. Which I think should be able to facilitate the cold restore option.. Is this a definite physical problem on the tape drive or is this an Informix bug.. I'll appreciate any assistance on the matter regards Roger The information in this communication and any attachments are deemed by PPSL to be confidential and may be legally privileged and protected from disclosure.
