I have an HP MSL 5060 tape library with 2 x LTO-1 tape drives. The
library is connected to a Brocade SAN switch via Fibre-Channel and the
2 LTO-1 drives in the library are SCSI daisy-chained and connected to
the library's NSR1200 FC-to-SCSI router.
On my backup server side (Sun 480R: tried Solaris 8 & Solaris 10 for
this), I have no problem seeing the library's WWN and its first drive
as /dev/rmt/0 with proper WWN-based zoning and HBA driver, etc. but no
matter what I tried, the library's 2nd drive is not visible from the
server. I am thinking of one possibility on the library side.
My existing other backup server (Sun 280R), though, has no problem
seeing both drives in the same library and I initially suspected the OS
side but I have everything installed and configured properly and don't
see anything wrong in both SW and HW sides.
So I know suspect the library side.
Is there some known problem that a host can see the library and its
drives only partially because of some firmware issue on NSR1200 router?
I have the latest firmware on the library and the 2 drives.
I'd greatly appreciate your advice!
