I'm wondering if this is indicative of a hardware problem, or whether it is a software one. The drive is already an FRU but it was working correctly up until the time we upgraded to 4.7 from 4.5. The drive is a sa0: Removable Sequential Access SCSI-3 device attached to a sym0: <875> port 0xc400-0xc4ff mem 0xda022000-0xda022fff,0xda021000-0xda0210ff irq 11 at device 17.0 on pci0 sym0: Tekram NVRAM, ID 7, Fast-20, SE, parity checking The backup script is nothing more than a tar command with -f /dev/nsa0. - Julian -- Julian C.
