Problems getting new LUNs under OS control (tru64 4.0g)

[Telia BackOffice]

Hi There

I am trying to migrate from one SAN cabinet (EMC DMX2000) to another SAN cabinet (EMC DMX3). All of this on Tru64 4.0g (1530) using an KGPSA-CA adapter.


This is causing me some problems. First of, the new cabinet was assigned an target of 9 causing a message in /var/adm/messages

Nov 25 09:27:37 mystix vmunix: emx0: emx_assign_fcp_id: nport at DID 0x3d9f00 as
signed tgt id 9 - out of range for CAM

After reading some documentations, I found out that CAM on tru64 4.0g only could address 8 targets, but that I could remap them arbitrarily using emxmgr. So I did (and assigned it to bus 16, target 3).

I then got

thosan@mystix|ttyp2:/usr/users/thosan$ sudo scu show edt

CAM Equipment Device Table (EDT) Information:

Device: SYMMETRIX Bus: 16, Target: 0, Lun: 4, Type: Direct Access
Device: SYMMETRIX Bus: 16, Target: 3, Lun: 0, Type: Array Controller

But this puzzles me. My new cabinet comes up as an taget of type: Array Controller, whereas my old cabinet does not show in the list, but instead I get the 5 luns that I have presnted as type Direct Access. According to the storage guys they have done what they could to present the new and old cabinet in the same way.

Please help. What part of the puzzle is missing here?! Some of you probably can tell me in a second why and how to fix :-)
