A real stumper. This is an ongoing problem. ADIC i2000, Netapp Ontap 7.2.3, TSM 5.4.1
I've isolated this so I know it'd not a TSM problem, but perhaps I can find some insight here. Describing it is a bit complex, but here goes. The drives are shared with 2 AIX hosts and 1 Netapp. (I've isolated the netapp, so I know it's not a tape reservation issue either) We have 16 LTO3 drives in an i2000 library. Every 4 drives are on an individual I/O board in the i2000, so as far as zoning goes, the i2000 is presenting 4 WWNs The Netapp has 2x dual port cards. 4 ports in total, 5a, 5b, 6a, 6b We have it zoned: 5A - i2000 card1 (4 drives) 5B - i2000 card2 (4 drives) 6A - i2000 card3 (4 drives) 6B - i2000 card4 (4 drives) On the netapp, I can see all the drives, and read all the serial numbers from the drives. Here is the problem. When I try to define a path to the drives only 8 drives are able to be defined. The rest fail with a ANR1737E. The 8 drives are all the drives on only 2 of the cards. Here is the rub, On the ADIC, I can reboot the 2 cards that didn't work, then the define paths will work. I can also "fcadmin reset_adapter" the interface on the netapp side to get the paths to work. But if I do that, the other 2 cards that originally worked, stop working! The pattern I've found is either 5A or 6B will work, but not both. 6A or 5B will work, but not both. When I've tried to isolate it, I've performed dumps from the netapp to physically mounted tapes, and it still behaves this way. For drives that aren't on a "freshly reset" card, I get an "illegal device" error. But I simply reset the interface, then the dump works fine. One more strange thing. I can start a dump to 5A, reset 6B and then start a job on 6B and both will run concurrently. But when the job finishes on 5A, I won't be able to start another. I have cases open with Quantum and Netapp, but they are stumped. ________________________________________________ Shawn Drew Data Protection Engineer Core IT Production BNP Paribas RCC, Inc.
