[Veritas-bu] Tape drives not seen - fibre channel config

Greetings,

I know this isn't a specific Veritas question but I'm guessing someone may have run into this problem while setting up a new installation.

I'm trying to get a new 6.5.3 installation ready for some testing on a linux RHEL 4.5 server using a qlogic QLE2462 card. The tape libraries are HP/Compac MSL6000 libraries with Ultrium 2 drives and the e1200-160 fibre bridges. For this test I'm using a Brocade 3800 silkworm.

The problem that I have is nothing past the robotic controller gets recognized on one bridge. The robotic is lun 0, and then drives at lun 1 and lun 2.

Is there some lun mapping or instance type issues associated with linux or any of the pieces I'm trying to put into place? The output of /proc/scsi/qla2xxx/0 is below. You can see it sees both targets but luns 0-2 on Id 0 say they are not registered for some reason. Lun 3 is the robotic controller but the fibre bridge actually has the robot as lun 0. I'm not sure why it shows up here as 3.

( 1: 2): Total reqs 2, Pending reqs 0, flags 0x0, Dflags 0x0, 0:0:82 0c

Any ideas why the system isn't seeing the drives on ID 0? The library I'm zoning into for these tests is a production box so I don't have the option of changing ID's on the fibre bridge.

Thanks,

Jeff
