Console LUN id - EVA
Is it possible to change the console LUN id without any disturbance to the hosts (Windows) already connected?
Regards, Torfi.

Re: Console LUN id - EVA
What "ID" are you talking about? The 128-bit LUN WWN or the "OS Unit ID"? The second one isn't even used by Windows.

Re: Console LUN id - EVA
I am running OpenVMS and the intallation guide states that it is important to have the value set to a number other than zero. I have posted another question on the OpenVMS forum about the necessity of doing this (as I can not really see or understand the need). So if OpenVMS really need this to be set as not zero then I have to change it and I wanted to know if that could have any impact on the Windows machines.
Torfi.

Re: Console LUN id - EVA
There was a short time during initial fibre channel support for OpenVMS (V7.2 + patches, HSG80 ACS V8.4) when it was required to set a 'unit identifier' on the CCL - else, OpenVMS could not configure any disks, but as far as I am aware, this is no longer necessary and, again, as far as I know, OpenVMS does not have any support to receive management events from the EVA (cannot enable direct eventing when a Host had OpenVMS profile) and there is no management agent for CV-EVA/ SSSU evailable either.
The value for this 'unit identifier' is stored in a vendor-specific SCSI page that is only used by AlphaServer boot support in the SRM console, OpenVMS unit assignment and Tru64 Unix can display, but does not require it.
