Problem with L1000 11i talking to ADIC Scalar i500

[Dave Johnson_1]

I have a rp4440 running 11i that is able to talk to the i500 no problem. I also have an L1000 that was upgraded to 11i using the DVD that came with the rp4440 that cannot talk to any of the drives in the i500.
I using the i500 web interface to load a tape in each of the 3 LTO-3 drives. I can then use tar on the rp4440 to write data to each of the drives. When I try to do any function on these tapes with tar from the L1000, after some timeout period I get a message
"# tar cvf /dev/rmt/8m
tar: cannot open /dev/rmt/8m"
The rp4440 is using a A6795A 2GB FC card and the L1000 is using a A5158A 1GB FC card. The rp is connected to a new 4GB Brocade SAN switch. The L is connected to an old Brocade 2800 1GB switch. Both switches are connected together. The LTO-3 array is directly connected to the 4GB swith. There are also LTO-1 drives on the 2800 switch. The rp is able to do backups to the LTO-1 drives on the 2800 so the switches are talking properly.
Both servers have "FibrChanl-00 B.11.11.12 PCI/HSC FibreChannel;Supptd HW=A6684A,A6685A,A5158A,A6795A" installed.
Both servers are also connected on other identical FC cards to an XP disk array, and that works normally so I assume the FC drives are OK.
I have tried to deleted all files in /dev/rmt, ran ioscan -fC tape, then insf -eC tape. The results were the same, no joy on the L to the tape drives.
Any suggestions would be appreciated.

Bounce this back to the head of the list.

Can you post the output of ioscan ?
Specicially the h/w path tree at/down the FC HBA connected ( fibre ports which are supposed to be zoned to see the i500 ) on L1000 ?

Well, this information good to know. However important ioscan information about FC HBA h/w paths 0/7/0/0.1 & 0/7/0/0.2 and down is needed.

Can you also post output of
# fcmsutil
# fcmsutil devstat all

I guess zoing is properly done?

[Dave Johnson_1]

I ran the command on both servers and get the same response "Error: FCP driver not loaded."

Just pushing this back to the top of the list.

I have tested using a 2GB FC card in this server to talk to the
LTO-3 tape drive. That worked with out any software changes. In
the event I still need to have this server talk to the tape
array, I will perminatly install a 2GB card.
Thank you for your help.
