Dell Poweredge 2600 drive/RAID questions

By osama_ssuetians ·
Hi,

We have a Dell poweredge server 2600. It consists of 5 HDD SCSI all of them belong to Brand MAXTOR and are of 40 GB capacity

Now One of the HDD went bad we replace the hard disk with a 70 GB SCSI HDD

But still it is showing array Failed, now my question is that do we have to rebuild the array or it will be automatically created

NOTE: SERVER IS DELL POWEREDGE 2600

WE ARE USING RAID LEVEL 0 AND RAID LEVEL 5

Please help

You'll have to rebuild the array. You'll also only get 40 GB of the 70GB drive. It may also give errors because it doesn't match the other drives in the array. It's usually best to replace like with like.

If this drive was part of the RAID ARRAY it needs to be the same size as the other drive that it's mated to.

You'll also depending on the controller need to rebuild that part of the ARRAY. Even if the RAID Controller supports the Auto Rebuild Function you'll still need to launch this to rebuild the ARRAY.

If it's the Boot Drive you need to reestablish the RAID Environment to get the RAID to function properly.

Hi,

The PowerEdge 2600 does support auto rebuild functionality when a failed drive is replaced. However if drives with different capacities from different manufacturers are mixed in a RAID environment then the rebuild may not happen.

I would suggest checking to see if the drive is supported on the 2600 (Maxtor, Seagate, Fujitsu, etc should all work fine). I would also suggest updating the firmware on the remaining Maxtor drives as there may be an issue with SCSI timeout errors that caused your disk to fall off its array. If you want to find out if there are any potential problems with any of your disks you should check the hardware/controller logs. Specifically look for predictive failure errors or sense key errors. If there are no errors in the hardware logs and no media errors in the PERC BIOS then firmware is the most likely culprit for any failed HDDs.

You can find firmware/driver updates for the 2600 with Win2K3 here: http://support.dell.com/support/downloads/devices.aspx?c=us&l=en&s=gen&SystemID=PWE_FOS_XEO_2600&os=WNET&osl=EN
or for Win2K here: http://support.dell.com/support/downloads/devices.aspx?c=us&l=en&s=gen&SystemID=PWE_FOS_XEO_2600&os=WNT5&osl=EN

As mentioned in a previous post you will only be able to use 40GB of the new HDD. It is possible to utilise more of this space if the HDD is in the RAID 5 array, but it will end up causing more problems than it solves.

If you have Open Manager Sever Administrator or Array manager installed you can also use them to manually start the rebuild. Alternatively you can start the rebuild in the PERC BIOS.

Please note: If the failed HDD was in the RAID 0 the data is lost and a rebuild is not possible.
