Hello,

Today I noticed that most of my VMs weren't accessible.

Once i checked the system, I noticed my FC channel SAN data domain is inactive.

My attempts to activate my data center storage is failing as well.

I don't see any errors in my engine log under /var/log/ovirt-engine.

Any idea why my storage is not coming up?

Thank you,

Jean
