Hi there, I was hoping to provide a couple of (very old) tape drives to my Xen VM clients, by making the drives visible as iSCSI targets.
Unfortunately: bash-3.2# iscsitadm create target --type raw --backing-store /dev/rmt/0 rmt0 iscsitadm: Error Backing store is not valid raw device bash-3.2# mt -f /dev/rmt/0 status Exabyte EXB-8500 8mm Helical Scan tape drive: sense key(0x5)= Illegal Request residual= 0 retries= 0 file no= 0 block no= 0 bash-3.2# uname -a SunOS ultra10b 5.11 snv_79a sun4u sparc SUNW,Ultra-5_10 bash-3.2# Sending a 'rewind' clears that Illegal Request status [again], btw: bash-3.2# mt -f /dev/rmt/0 rewind bash-3.2# mt -f /dev/rmt/0 status Exabyte EXB-8500 8mm Helical Scan tape drive: sense key(0x0)= No Additional Sense residual= 0 retries= 0 file no= 0 block no= 0 bash-3.2# iscsitadm create target --type raw --size 2G --backing-store /dev/rmt/0 rmt0 gives just the same error, so the problem isn't just from guessing the tape "size". Xen's running on Ubuntu 7.10 (patched with the latest open-iscsi, to fix Ubuntu's iscsi login kernel panic..) and linux can fdisk, etc., iscsi disk targets from the Solaris box; so iscsi's happy both ends. The tape drives work fine locally (tar cvf, tvf, etc.) from Solaris. I'm guessing the "change the daemon" comment in this next post still applies; anyone confirm, please ? http://osdir.com/ml/os.solaris.opensolaris.storage.general/2006-12/msg00056.html Finally, if I can't make targets of the tapedrives using Solaris, any other OS pointers / great ideas, to present tapedrives under Xen ? I think IET on Linux allowed this, but I'd have to go back a couple OS revs to get it to compile, so I'm not hugely keen...
