I have a HP MSA 2012i Storage device, and (3) ESX servers.
I had a pre-existing volume on the HP MSA that is seen by all three servers without issues.
VMDKS are running on this just fine.
I created a new volume and rescan the VHBAs and tried to "add new disk" under storage like normal, but nothing populates.
I know the esx servers can see the MSA, as it saw and created the first volume without issue.
Also CHAP is not enabled. and on the new volume, all esx host have permissions to this.
I looked in the /var/logs/ and found the following,
Need help getting this new volume connected to the esx servers.
