Storage only visible to one host

[gheywood]

Hello,

I have a cluster of five hosts connected to an Equallogic SAN. I added a new volume, added the iSCSI initiator ID’s in the access tab, did a rescan on a host, and created my volume. So far so good. I then did a rescan on the other four hosts assuming that they would connect. They haven’t.

There are two times I have seen this before. One is when the access is not set correctly (I have double-checked this), and secondly, when the checkbox to enable multi-host access is not checked (it is). Also I know the latter generates a warning on the SAN and I am pretty sure the former does too. I haven’t see any warnings. So I am assuming that it isn’t either of these.

The next thing I did was put a host in maintenance mode and reboot it, then do a rescan when it came back up. Unfortunately that hasn’t helped either.

Has anyone seen this before? It looks like the hosts are not event attempting to connect to the volume..

Please post screenshots with storage devices on hosts.

Now resolved. Vmware called (very quickly actually).

There were SQL errors in the /var/log/vmkiscsid.log file which indicate a corrupt database.

The solution was to put the host in maintenance mode, delete /etc/vmware/vmkiscsid/vmkiscsid.db-journal, and reboot. That fixed it.

A bit strange that it added to the first volume OK and corrupted the all the other hosts, but the problem is resolved with (thanks to DRS!) no user impact.
