SAN Storage: CLARiiON LUN0 devices

This week I’ve had a problem with CLARiiON SAN Storage that needed to be investigated.

Here is my findings:

Problem: When provisionning a Host LUN0 CLARiiON disk on a server, sometimes it is not taken into account by MPxIO. Resulting in no multipathing available. (Although, single devices are available & working…)

Reason: Once MPxIO has seen some LUNZ (Gatekeeper) devices on a server, it consider every LUN0 devices as such, and don’t take them. As LUNZ are provisionned with Host Lun 0, when a real LUN0 disk is provisionned, problems comes.

Read the article to see the solution 🙂

Veritas vs Disksuite, Who will win ?

For being sometimes called at night for work, I know this could be of two case: A little problem that could be solved on the phone, or a big mess that needs to be cleaned all the night long.

This one was a big mess.

A big solaris machine who was hosting a buch of zones had lost the disk of one of them.. causing the zone to be down. Veritas showed the disk properly online with two enabled configuration zones

On that disk. Until this, everything fine.
