msa1000 controller config backup?

kelly trosper — Mon, 13 Dec 2004 19:04:43 GMT

Hi, we're carving up ~9TB hangin on an MSA1000 (dual controllers, dual san switches, etc...) I don't think the odds of both controllers is very high, but I'd like to backup the config, just the same.

Can I do that?
What's the recovery proceedure if I lose both controllers?

Thanks.

Sorry... I meant, I don't think the odds of LOSING both controllers is very high...

Since this is a Smart Array type of device, the config should automatically be stored on the drives. that is what makes migration supposed to be possible from the older 4100's and stand alone controllers.

Now, I have never had to recover from a dual controller failure, but the Smart Array technology is supposed to make it simple. Just replace the controller and it should read the config from the drives, like servers read the config fro drives of other servers.

I do not think there is a way to physically backup the configuration. I could be wron though.

Kelly,

If you lost both controllers, your config is still held on your hard drives. If you want the full config documented, it would be best to go into the CLI and run show tech_support
This will output your configuration which you could save as documentation should you need it.

Good Morning Kelly,

Your configuration is stored on the drives.
During controller boot, it will read the your configuration off the drives.

But for added caution you could save your configuration to an .ini file. I'm going to assume you used ACU to configure your MSA. If you go to the cmd prompt locate under "Program files" -> compaq -> cpqacuxe(hpacuxe) -> bin.
Run
cpqacuxe(hpacuxe) -C [Drive:][Path]Filename
If no capture file name is specified, ACU gives the file the default name of ACUCAPT.ini and places it in the ACU working directory. Keep the first two lines, edit out the internal smart array information.

If some accidently deletes your LUN, you can input this file to recreate you LUN.

cpqacuxe(hpacuxe) -I [Drive:][Path]Filename

The braces next the program name mean either or. Different ACU versions.

Recommend reading Chapter four in the ACU user guide.
