@Dashrender said in Dell PERC Question (Server Down):
you rebooted after it started a rebuild? That wasn't wise.
That's what I have seen all the DELL techs do.
I doubled checked tonight and that it definitely the supported way to go.
I've been a Dell tech. They are not trained and are just random people grabbed from third party staffing firms at the last second. Never use "Dell techs do it" as a guide to anything. It's the same as saying "random out of work guy did this".

Sorry, I didn't mean the techs who come out to your location. I mean their US-based phone technical support.
Is that who you mean? Is technical support safe to trust?
-
Also, what is your take? Safe to reboot on a rebuilding array if you have to configure it from the controller config in BIOS?

Probably. But... that was a very reckless decision on their part. So... no.

No, it's reckless and crazy. You don't induce a failure risk during a repair operation.
-
If it is rebuilding, why is configuration needed? Any why is configuration limited to the BIOS?

Because when this happens, the drives totally disappear from the PERC config and the server crashes. You have to go in and clear the foreign config. There is nothing to rebuild.
It's not like a drive has failed, and the LED is orange and you can pull it. Nothing like that.

I mean the PERC configuration utility access during POST but hitting <CTRL>R.

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.

The PERC is up. It's just the drives aren't. Certain drives aren't. The DELL 7.2K SATA drives I have in an array have not dropped off or made a peep once.
The DRAC isn't so great at managing storage or talking to the PERC, or so I have been told. (Those the remote console is worth its weight in gold)
-
Are you booting from SD card? That would solve the issue, right?
-
@scottalanmiller said
Not yet, but soon.
And yes, I know that if I was booting off USB/SD I could have copied the VM to my other storage repository and then redid my array.

Yes, that too. But I also mean that the array could be managed without a reboot.
-
That's anther good reason that we don't normally think of for installing to SD/USB.

@scottalanmiller said
Yes, that too. But I also mean that the array could be managed without a reboot.
You can install OMSA to a VM? I didn't think it would be able to access the hardware.

You install directly to XenServer's Dom0 which has hardware access.

I was going to ask about this in my roadtrip of XS.
So, then how do you access it? From a web browser just like any other OMSA install?
