Dell PERC Question (Server Down)
-
@BRRABill said in Dell PERC Question (Server Down):
I did a few Google search. It seems like other places (including Adaptec) also say rebooting a rebuilding array is perfectly safe.
Of course they do, you are reading their marketing.

VMware advocates moving running workloads around, too. But you should fire anyone who did it in production based on that recommendation. I've seen people do that thinking that they would not get caught because "Vmware said it was safe" and brought down a bank because of it (hint: it wasn't safe.)

That means that the PERC has failed. That's a different issue.
Are we back to that?
I mean, it's definitely on the table. Just not sure why all of a sudden you think that's so likely.
Because you said that it was rebuilding. The PERC should remain up and viable even without disks attached to it. You can continue to manage it online through the iDRAC or a VM that isn't using those drives.
You do not manage Dell PERC through iDRAC or a VM.

I've done it many times over the years and never once had a failure. Yes it is a risk, but it is also adding downtime waiting for a rebuild to happen.

Do you mean that the OMSA can't manage the PERC?
-
Does this not work for the iDRAC?

The iDRAC is not OMSA they are different.

OMSA can do things.

Right, using OMSA in the Dom0 should work fine for working with the PERC. Unless I've missed something.

Yes, but my point was you claimed to use iDRAC.
-
I was going to log into the iDRAC and get a screen there to show the difference, but for some reason it is not pulling an address..

You people need to quit making me work!

The OMSA was in reference to managing via the Dom0.

I claimed both, but as two separate means of doing it.

That is what I was saying, that the iDRAC is pretty powerless with storage.
I'll work on getting OMSA on the XS.

No, I missed it. How slow was it?
So is somewhat slow speed OK for booting/updating off USB2?

And after a long drive!
So sorry!

Sure, what difference does the boot speed make realistically?

Did my link about that not work?
