FC attached tape drive not writing

Hi,

We recently added four LTO-5 tape drives. We zone them and they show up when I run "storage show tape". However, when we run a backup job via NetBackup, it is not writing anything. I ran backup status and I don't see anything. I know that NDMP is working because if in NetBackup I point the job to the other filer's tape drives, it runs.

I see these error messages:

scsi.cmd.pastTimeToLive

Tape device HQ2-blahblah: request failed after try #1: cdb 0x0a

tape.device.cmdAbort

Tape device HQ2-blahblah: command aborted by host, ha_status 0x4

Anyone knows what I am missing?

options tape.reservations persistent

NetBackup does not support anything else
