Setting up a hardware raid configuration remotely can be a rather tiresome task if you do not happen to perform such on a daily basis. Using LSI’s web based client via IPMI can be an extremely nerve wrecking pastime, and since we have run into this scenario a couple of times already, we thought it might be useful to post a very quick getting started guide.
Getting into the configuration shell
- Connect to your server’s IPMI and launch the remote console.
- Boot the server and enter the preboot client shell (CLI) when the option is presented on screen.
How to create a virtual drive
In the shell, list all your physical disks this way:
This will list all physical devices on all adapters. There will be a lot of scrollage, so you may need to capture (if pause does not work – which is often the case…) the screen with the inbuilt video capture functionality. You will need the following values:
- adapter ID (usually 0 or 1)
- enclosure ID (often 252, but not always)
- slot ID (per disk, varies)
Next, create a virtual disk with your desired RAID setup, e.g. a simple Raid 1 can be done this way (assuming we have the controller’s ID as 0, enclosure ID 252, and the two disks in question on slots 2 and 3 respectively):
-CfgLdAdd -r1 [252:2,252:3] -a0
You are good to go now – reboot, and your OS should pick up the virtual disk now.
