HP rp5450 (L2000)
running HP-UX 11.11B
Using DLT 7000 and DLT 4000 tape drives for nightly full backups
Backup jobs created by SAM
DLT 7000 cron entry is as follows:
00 2 * * 1-6 /usr/sam/lbin/br_backup DLT FULL Y /dev/rmt/0m /var/sam/graphLCAa17036 root Y 1 N > /var/sam/SAM_br_msgs 2>&1 #sambackup
On the DLT 7000 have been getting failures for the past month or so, most of which are "write error on a record in the index".
Have tried swapping tape drive positions in the enclosure (SCSI bus) with no luck.
Have tried different tape manufacturers & new/old tapes with no luck.
Have tried multiple DLT 7000 drives with no luck.
Backup jobs using to DLT 4000 are working successfully for same dataset.
Any ideas as to what is causing this failure & how to resolve?
Thanks
