Do you use separate adapters for tape i/o and dsik i/o and tape i/o ?
If so you kan try to set your switch tape poorts in G mode.
This mode wil force your poort to initiate a Fabric mode login of your drives instead of a Loop mode.
Earlier Firmware levels of LTO2 drives still log in as a Loop devices instead of a fabric device...

Hi list,
i have a question about SAN design. We plan to connect a 3584 with lto2 units in a disk-san environment . There are enough ports to connect all units.
But a cutomers describe a problem with tapeunits in one san (disk+tape). When he create new zonings or do changes in the san a "remote state change notification" for all components is send. When a backup is running on TSM the backup failes. The tapedrive becomes this "rscn" and do a "fabric_logoff" "fabric_logon" (not the right description) to update the new san-configuration.
Have anybody seen or listen this problem ? Is that a real problem for mixed san components (disk+tape) for TSM?
I have told ibm support for a answer but there are no recommandations to split a san or create two fabrics one for disk and one for tape devices.
Any idea
kind regards
