I got an email from Mike asking about his Compaq DL380 server, the disk has failed, they called an engineer out and he’s swapped it.  How does he know if the drive has rebuilt? I’ve included my response below:

Hi Mike,

Not a problem, your engineer should have checked it rebuilt before he left, but typically the drive should automatically rebuild in about half an hour or so, it depends on the size, file structure and how busy the server is. (There is also a setting on the controller to set this), the same principles apply to HP servers, though the agents are renamed and updated.

There are a few ways to tell if your drive is rebuilding:

• Event viewer on Windows – it will show drive failure, drive removed, drive inserted and drive rebuilding, once it’s rebuilt there will be an entry saying the drive status is now rebuilt.
• Compaq Array Utility – this is part of SmartStart drivers/applications, run this tool and it will show you a diagram of your drive status
• Compaq Web Agent – if you’ve installed the Compaq web agent, on the server, you run http://insertyourservername:2301, then log in, it will show you if the drive has rebuilt, by basically showing you the array controller status on the web page.

Basically using the compaq tools, everything should be green and there should be no errors on screen, you could also check the compaq integrated management log, though if memory servers, it doesn’t state drive rebuild, just failure.

Physically look at the front of the servers on the drive. If the drive is rebuilding, the drive should be flashing to illustrate it’s rebuilding the array or disk.

Hope that helps.

Regards

Martin
