AIX

Hello All,

Really hoping someone can help. We have an AIX server connected to a Quantum SDLC sitting in front of an S10K library. The library has 3 logical partitions (two LTO4, one LTO3), so it requires 3 distinct medium changers. The SDLC presents the 3 luns (which are the medium changers) on the same WWN. We are able to see lun 2 (LTO3 partition) on that WWN, but are unable to see luns 0 and 1 (LTO4 partitions).
The SDLC is definitely presenting the luns. However, I'm unable to figure out why I can't see luns 0 and 1 a this point. We've upgraded the ATAPE driver on AIX and rebooted the AIX server to no avail. Anyone have any ideas? Thanks for any input.

How is it attached? FC? SCSI? Via some switch or directly?
Do these devices require some special AIX TL/SP?
If FC connection and switch involved, maybe a zoning problem or would you not see LUN2 either?

There are tons of documentation for this stuff:

They also have a knowledge base - checked them yet?
