ESX on EVA - Console LUN ID?

[mlwalker]

I have ESX 2.5.3 in production on an EVA 4000. Whenever I go to Storage Management I always get a pop-up about the partition table & "geometry info is invalid". After clicking OK to rescan the SAN, everything is fine. I have been told this is due to a management LUN on the SAN (Console LUN ID = 0 ?).

Is there some way to mask this management LUN or change it to a higher number to prevent this pop-up all the time? I have attached a screenshot of the pop-up & CommandView EVA settings. We only have one shelf and it is partitioned as a single 655GB vdisk\LUN - we might be getting another shelf, but I'm not worried about hitting the default maximum LUN count for awhile.

thanks,
mike

The SACD (Storage Array Controller Device, in EVA's terminology) is needed for in-band management and SCSI-3 style LUN detection. It cannot be disabled or moved to another LUN *address*.

You can change, what is shown as the so-called "Console LUN ID" in CV-EVA, but:

- it does *not* change the LUN *address*
-- (the last zero in "vmhba1:0:0")

- VMware ESX server does not use this *ID* anyway


I currently have ESX V2.5.3 patch3 running on an EVA4000 and I do not get that message, by the way. What value did you choose as "Host OS Type"?


Some other notes:

- the minimum required XCS revision is V5.031, but you EVA is at V5.020

- there should be a minimum of 5 raw GigaBytes free in a disk group, your array is *way* below this level
