Failed physical drive alert - how can I fix it?

Josepbcn — Sun, 12 Jun 2011 15:55:54 GMT

The Array Configuration Utility says that I have a failed physical drive on Bay 3, but Bay 3 is empty. I do not know how to reconfigure or fix this.

More info:
I am using a Raid 5 configuration, with 3 physical drives.

This is what ACU says under "Physical Drives":
0 MB SAS Drive at Port 1I : Box 1 : Bay 3
146 GB 2-Port SAS Drive at Port 1I : Box 1 : Bay 1
146 GB 1-Port SAS Drive at Port 1I : Box 1 : Bay 2

And under "Spare Drives":
146 GB 2-Port SAS Drive at Port 1I : Box 1 : Bay 4 (Active Spare)

Since Bay 3 is empty, I guess I should configure the Array to take that into consideration.
But I am not sure how to proceed. I read all the manuals and still don't know.
Can you help?

thanks

I should have mentioned before: I am on Windows Server 2003.

I guess 'ioscan' would be for a Unix box.
What would be the equivalent in Windows?

have you configured with 3 drives previously and then remove one and then added as a spare. raid 5 can not be configured on 2 drives. there must be present atleast three.

run hardware detection wizard in windows server 2003.

I have two drives, on Bay 1 and Bay 2.

Then I have another drive on Bay 4 (that appears as "Active Spare"). I am not sure what it means.

Initially, Bay 3 had a drive, but it is empty now, because the bay seems to be failing, and our support guys told me to stop using it.

Is it possible to use Bay 4, with its "active spare" drive, as part of the Raid 5 configuration?

dear

raid 5 work in by putting all disks together other wise your raid will be break without three drives. put all drives together to avoid any mishap.

thanks for your help and patience.

I am trying to put them together as a Raid 5, but I don't know how to do it. I have 3 physical drives, so I understand I have enough drive, but I do not know how to continue.

What would be the procedure in Win Server 2003?

dear,

put them in sequence. first on first bay,second on 2nd place and adjust your 4th bay drive on third location. if data is not critical you can make new raid 5 again.

Ok, so if I swap the drive currently on Bay 4 and put it back on Bay 3, it should work correctly.

Is there any way to use the drive on Bay 4 as part of the Raid and leave Bay 3 empty?
The reason I'm asking is because Bay 3 seems to be broken (it has damaged 2 drives already), and wanted to avoid using it.

first if the product is under warranty then first try to replace the part. second use bays from 4 to 6 if warranty is not covered.
