XenServer 6.2 servers down. I have no Xen skill. Most likely networking? Help!

[root@xen2 log]# tail -n 100 xen tail: error reading `xen': Is a directory -
@CitrixNewbJD hardware seems to be fine.

How about this command:
xe pbd-list -

Who is spindleinc\mgould? Is your Xenserver setup with AD integration? it looks like this is the case. Is mgould a disabled account in AD(this seems to be the guy who had your job, maybe). If so, that is a huge issue.
Is there a reason you have 5 ISO libraries? -

Is there a reason you have 5 ISO libraries?mgould is still with us. I don't know if it was set up with AD integration, but I would assume so based on this. It's not a disabled account, but we can't get to AD.
I have no idea why we have 5 ISO libraries.

Oh, you cant authenticate to ad but all your SR need it to attach
That is the problem right there i think. -

That's not good. AD was built on top of a system that was merged with all shared dependencies... so AD needs Xen which needs the PowerVault, which needs Xen which needs AD. So the circular issue potentially? There is no AD to fail over to if anything goes wrong with the Xen cluster has no redundancy. No matter how many copies run on XenServer here, there is only one disk array holding it all.

No, just really REALLY silly.

@momurda from a quick glance those appear to be all CIFS ISO repos that are AD tied, so we should be able to just remove those to fix that, right? I don't see anything else.
-
@CitrixNewbJD
No i dont think so.
You got some work to do though
Probably need to do:
log into the san and change the creds for iscsi, disable ad authentication in xc, and then probably forget/reattach the sr -
I always try to make sure that I have an administrative local user to every system, just in case I cannot get to AD.

That, and never have AD on top of something that depends on it. That's like locking your keys in your car.

Yup. Our SAN is isolated from the rest of the house network physically. All authentication between the SAN and the host should never even touch AD just in case of things like this.
Sometimes playing what-if is a good exercise to keep bad things from happening as far as security, reliability, and recovery.
-
@scottalanmiller
Yes the cifs repos can be forgotten for now. I doubt there is anything important there in the iso repo.
@CitrixNewbJD
Before you do anything else, make sure you have the root pw for your xs servers as disabling AD integration will force you to use them. -
Unless you have a DC that you can get working, ie one not attached to your shared storage. Perhaps you have a physical dc somewhere? Unlikely i know.
-
@CitrixNewbJD This is Frank. I hope Scott and the gang here can help get you back operational quickly. To touch on a topic that was mentioned earlier, VMs from Xen can be imported and converted on the fly. As long as the Scale nodes can browse to the VM files (.vhd) on the storage, the XenServer functional state doesn't matter.
