Pavilion ML150 G2 RAID Issue with beep sound all the time

[luis inzunza]

Hi,
I have this server and it's making a beep all the time, it doesn't stop until I shut down the computer and when I turn it on I get this message
"Following Arrays have missing or rebuilding or failed member and are degraded.
Array#0-RAID5"

I check the system log and I found this error:
Source: aac
Event ID:9
The device,\Device\SCSI\aac1 did not respond within the timeout period.

I'm not very familiar with RAID configurations and I don't know how to fix it. Is it just I need to change the drive and that will be all?
Any help?? I will really appreciated.

I was able to resolve my server problem by replacing a bad HD in the raid. They were hot swap drives, which means you can replace it without turning the server off, and it will start to rebiuld on its own. I found the bad drive by going into the raid configuration tool to see which drive was bad. Hope that helps.

Thanks Lisa,
the configuration tool is the one you access before log on to windows with Ctrl + key ??

where did you buy your HD??
Thanks in advance!!
