Ok, from the top. We are running a new Dell PowerEdge 2950 server with Windows 2003 SP2. We have installed an LSI Ultra320 SCSI PCI-e card, connected to a Quantum Superloader 3 autoloader with a Certance LTO2 tape drive inside. We are running Backup Exec 12.0 SP3. We ran the Superloader on the previous backup server without any issues, running Backup Exec 10d on W2K3.
The backup jobs seem to run fine until the verify stage where they fail. The resulting error, E00084C8, points towards one of the servers' files exceeding the available Paged Pool Memory size. The link (pointing to MS article KB304101) recommends creating/editing the PoolUsageMaximum registry key and setting it to 60 (%), reducing the figure if the problem persists. I have worked down to 40 and the problem still occurs, although not on the original backup job that failed with this error. So it's like it's helping, but not solving the problem. How low can I go??
Simultaneous to the backup verification failing, we are getting errors in the system log, event id 11, source: Lsi_scsi, that say the driver detected a controller error on \Device\RaidPort1. This worries me because the autoloader manual says the autoloader is not recommended for use with a RAID controller. However we have been running the superloader on an LSI Ultra320 PCI card (not PCI-e) in the old server for years without issue. We would have transferred the old card to the new server but the Dell only has PCI-e slots.
Further, the backups are successful and the verify progresses to a certain point before failing. I can also successfully restore data from tape. Last night's backup was 100% successful because I turned off data verification. So I can't see how it can be hardware related.
