I'm running ArcServe 2000AE with service pack 4 on a WinNT 4.0 SP 6a box. Library is a Quantum ATL PowerStor L500. I'm using a GFS rotation scheme. I'm getting a sporadic problem. My daily backups are working fine, but Arcserve can't seem to access my weekly media pool. If I inventory the tapes in that pool they show up from then on as "updating". If I go to inventory again, or format, those tapes don't even show up in the list. I have to restart all the ArcServe services to get visibility of those tapes back. Has anyone seen this type of behavior before?
