What is the network setup on these servers and the SAN?
One switch, multiple switches? how many connections to each server? etc.
2 switches. I tried reaching out to the guy that set it up 6 years ago, and he said he doesn't even remember how he did it. It was the last time he did a XenServer and PowerVault setup. I can get you the networking info from the XC and from the PV, and maybe we can find info for the switch that way, but I have no documentation for it.
In my defense, I've been lobbying for a replacement for this setup. Hopefully, it's coming due now.
XenServer is very good, but the version you have is old and not maintained. Having it with the PowerVault was never acceptable. That was a bad setup. XenServer is a very good choice. But if you don't have a XenServer team, you'll want something else. Of course, @scale is a good choice, but you already know that
Moving this to a Scale cluster would be a quick fix that would address both the compute and the storage needs and let you move to a far more reliable setup.Is it possible to somehow spin up what we have on a Scale cluster as is?
Not quite, we need a means of grabbing the files off of it. So we either need a utility to do some conversion which I think Scale can help with; or we need to do a P2V process which requires us to get this working (even if just limping) in the mean time.

The iSCSI host ports on the SAN are 192.168.130.101-104. No gateway, no reference to a switch that I can find. I'm hoping a guy that's at lunch has some documentation to help out with that.

I dont think that that is where we are stuck, so that's good info to have but not in our critical path at the moment (I don't think.)

We still need to see the logs
[root@xen2 ~]# tail -n 100 messages tail: cannot open `messages' for reading: No such file or directoryThat's not good. That means that something really went wrong. Probably the disk had filled up.
Is there another way to view log entries?

Not if they are not there. That's not a log viewer, that's the logs itself. Are you use that you used the cd command to get into the right directory before trying to view the logs?

I used no cd command. I just tried "cd /var/logs" and was told there was no directory.

We still need to see the logs
[root@xen2 ~]# tail -n 100 messages tail: cannot open `messages' for reading: No such file or directoryThat's not good. That means that something really went wrong. Probably the disk had filled up.
Is there another way to view log entries?
Not if they are not there. That's not a log viewer, that's the logs itself. Are you use that you used the cd command to get into the right directory before trying to view the logs?
I used no cd command. I just tried "cd /var/logs" and was told there was no directory.
We are definitely seeing a problem here

No idea, but it's not from ML, that's from his cut and paste. Those spaces are all in his original.
