adding EMC-CX600 LUN: format gives "drive type unknown"

Hi,

we have a E15K domain running Solaris-8, and connected to a SAN via
QLogic-2300 Host Bus Adapters.

A bunch of EMC-Symmetrix disks are already made available to the server
and being used for filesystems through VxVM.

Now we need to add an extra LUN coming from an EMC-Clariion CX600 array.
The new LUN is discovered with SCSI-probing, but showing up in "format"
as a "drive type unknown" ...

When I try to let "format" "auto-configure" the disk type (option
"type", then select "0. Auto-Configure") I get the message

Auto configure failed

Within "format", the "inquiry" option yields

Vendor: DGC
Product: CX700
Revision: HP03

In VxVM, I have added the JBOD id with

vxddladm addjbod vid=DGC pagecode=0x83 offset=8 length=16

The people here told me that in previous attempts to make new
Clariion-LUNs correctly identified by Solaris on a machine that has
already Symmetrix-LUNs, was only after a reboot ... Which is surely not
the procedure I want to adopt (production servers, hey)

Any suggestions what can be done about it ?

TIA

Rob
