159.0. "backup/verify errors with hsz writeback cache" by NEWVAX::DISNEY (Jim Disney, phone 410-643-5578) Fri Feb 07 1997 12:22

My customer is getting OVMS BACKUP/IMAGE/VERIFY errors when backing up to an 
HSZ40 RAIDset with WRITEBACK_CACHE enabled, but not with NOWRITEBACKUP_CACHE
disabled. The backup data is dormant and about 4GB in size. I would expect a 
cache flush to occur prior to the backup verify pass and can't explain the 
verify errors. I ran diags (FMU and DECevent) and no errors. The HSZ40 (32MB)
is HSOF v3.0 (+ 2 recommended patches), OVMS 6.2-1H3 (+ALPSCSI02_070 patch).

Cache on or off should be completely transparant to backup operations.
If you're 100% sure that the file was closed during backup (and don't use
/ignore=interlock) then i think you should escalate this.

159.2possible hardware or firmware, not vmsNEWVAX::DISNEYJim Disney, phone 410-643-5578Mon Feb 10 1997 12:592
    Upon further investigation, it appears that the problem is hardware or
    firmware related, not vms.
