Adding additional Drive to XenServer host, get error
-
This is basically a fresh install. I installed XenServer from DVD to USB Flash Drive. I also have a freshly created Raid 1 volume (which is my intended target) and Dell disk backup drive.

The SR operation cannot be performed because a device underlying the SR is in use by the host.

Nuked host, rebuilt it from scratch and got around the problem. However I'm just interested in figuring out how to do the low level drive management from the CLI. I was able to get through it on my own by the seat of my pants. Just want some clarity. -
RAID is hardware?
-
@scottalanmiller Yes it is my Dell H200
-
Any suggestions as this one has my mind boggled.
-
Are you trying to add a drive to the array, or trying to add a new array to XS?
Within XC and XO you can manage the SR to mount, dismount etc.

You don't want to use that in product (or anywhere, really.) It's hardware RAID, but without battery, cache, or flash. Tons of people refer to it as software, but @manxam has tested it and knows the chipset. But I'd still not use it.
-
@scottalanmiller it's my old server. It works fine, not the greatest lol but works. Battery back up is in place. Cache and flash
you already know the answer.Are there any RAID Cards that are more modern that will fit the old server? Non Dell Perc obviously.
-
Scott I eventually just wiped it and started fresh but I learned a lot. At home I have been spending more time on the CLI with XenServer, no so much @ work as I only have 1 Raid array and normally don 't have to deal with CLI as much.
What I eventually did was nuked the raid, started fresh, changed it to a RAID 0 (for giggles), reinstalled XS. XS is installed to a 64 GB
-
At least it is working now.

Sure, pretty much any should work.
-
This is where I'm a noob at. I obviously trust the OEM/Included RAID card (even though they are rebranded). I don't know a staple RAID card to choose other than that
any suggestions? -

@black3dynamite correct me if I'm wrong, a Perc H700 won't work on a Dell Power Edge T110 i. Considering it is in same generation, I dunno but that would be basically stepping backwards, not forward.
-
I was told a few days ago the Dell R710 that comes with the H700 has craptacular performance issues with SSD. In my production servers I use H730's so I know and stand by them
But for my test server I dunno if it would work

#nooblevelAll older controllers are pretty bad with SSD. SSD requires so much more performance than controllers used to have.

@scottalanmiller You know a good staple controller you could suggest?

To control staple guns? Like a staple gun wielding robot?

Adapted and LSI are best.

@scottalanmiller you almost made me cry lol. I'm sick too
needed something funny to laugh about. -
