Integrity with A6826A recognize zero length LUN of EVA4000

[tommy_28]

Hi ,

A HP customer is using rx5670 connecting to EVA4000(via A6826A to SAN switch), after we prepare everything follow SPOCK indicated, such as kernel version, HBA firmware, etc. Before present anything to host, the server recognized two 'zero size' LUNs in EFI util.

Do you know what's wrong here?

Thx.

That's normal - it's the management LUN for the controllers.
