No, tape and disk reside on different fabrics. There are 7 tape HBAs, 3 of which go to physical tape, two of those have drives with this problem. Andy Huebner I am not aware of this problem. Are you

We had this problem as well. Our dedicated HBAs would just randomly log out of the Clariion. Presumably when a SAN Discovery "probe" went out. We couldn't get it to log back in without a reboot. A re
We will appreciate if someone can work with IBM support to report this problem. SAN Discovery is a very important TSM function and it is widely used by our customer. Regards, Jo Lay Tivoli Storage Pr

You are aware that under AIX if any WWN in the path of a drive changes, then that constitutes an entirely new device as seen by AIX. If you replaced GBics, it possibly could have caused the tape driv

The drives were verified in AIX after GBic change. Since there was not a port change there was no effect on AIX. The library is aware of all of the drives. I think I mentioned earlier that the AS/400
Andy, Do you have TSM SAN Discovery turned on? If you do, you can perform "q SAN" and look for the drive serial number in the output of "q san". If you have ran cfgmgr after you changed GBIC, TSM SAN

Ok, you might want to resolve the SAN Discovery issue on your machine. This will save you time in the long run. BTW, what is the issue for SAN discovery? Regards, Jo Lay Tivoli Storage Products, IBM

Here are some things to do . . . Check that the tape drive is logged into the switch port, and you see the wwn on the switch port. Check the tape drive that it sees the san - usually a light indicati

Hi, Andy. Going back to simple, in addition to deleting the paths, did you also delete and redefine your drives? I'm just double-checking because I don't see it explicitly mentioned in the thread and
You can issue a show library command from a TSM prompt. For detailed info that is not always represented in TSM. I've used this to see if tapes are stuck in older DLT drives. But it shows WWN and ser
OH, are only 3590's having problems??? We did a switch upgrade and the short story is that the switches we migrated to would not function with 3590's / 3590's would not function with the switch... I

IBM had me delete and recreate the drives in TSM. When we recreated the paths TSM was unable to contact the drive. AIX did not report an error. Since I am down to trying things that won't work I rese

If you use tapeutil to do an inquiry on a tape drive, the serial number should be recognizable in the output. You can compare this with the results from a "lscfg -vl rmt1" or "lsattr -El rmt1". I've
