Hi

Perhaps I misunderstood you, but the Qlogic adapters are oem:ed by IBM, so
if you buy a IBM FC adapter, this is normally a Qlogic adapter.

And the FC attached 3584 uses SCSI address translation against WWN. We've
got this running today on AIX, and if you do a lsdev -C|grep rmt, you will
get the scsi addresses for each drive. Same with the library(/dev/smcX).
This should mean that the Qlogic adapter can handle SCSI >> WWN
translation.

Best Regards

Hi all!
I believe I heard about an issue with Qlogic adapters and SCSI address
assignments. For Qlogic adapters you cannot define fixed SCSI address
assignment (fixed relation between SCSI LUN's and FC World Wide Name). So
if
another FC device is added to the host, your SCSI assignments are messed
up.
