Problem with iSCSI connected tape drive
Posted: Mon Dec 12, 2016 4:53 am
I'm exporting the target (an HP Utrium 460 LTO-2 drive) from Starwind V8 (free).
From my Linux system (Ubuntu 16.04.1 with 4.8.13 kernel), I did:
The rmtioctl message appeared after about 10-15 seconds, and the iSCSI target showed that the session had dropped after about another 15 seconds or so.
When I was returned to the command line prompt some time later, the target showed the session as connected again.
During most/all of this time the forward space file operation was still running.
Any guidance on fixing this will be greatly appreciated.
Thanks, Dave
