FC Luns w/DLT8000's not seen by IOSCAN
L700, 2xDLT8000's On LUNs 2 and 3.
Adic Scalar 100, 2xDLT8000's on LUNs 13 and 14 (plus the robot that cant be seen on LUN 12)
I have installed numerous patch sets for the 5158 tachyon and any other patch sets on all of these posts for LUNS or FC adapters. Wondering if i am missing something? Any help would be appreciated...

Re: FC Luns w/DLT8000's not seen by IOSCAN
renumber LUNs to be less than 8 (LUN0-LUN7). Libraries are usually shown as direct attached devices (using peripheral addressing mode - hwpath.sw#.pt#.255.alpa-hi.alpa-low.lun#) and can hold only 8 LUNs (3 bits representation)
I believe it will help

hwpath.sw#.port#.bridge-alpa.SCSI-bus#.SCSI-Id.Lun#
As we see lun, again, utilizes 3 bits only and can be 0..7
Move this lib to another SCSI channel, set it up not to work in lun mode (use scsi ids).

For perfomance reason maybe it's better, if you have one more free SCSI port on the bridge, to connect libraries to different ports? Think about it. 4 DLT8000 drives on the scsi bus is too many.... but 2 are ok.
