Array not being recognized within Windows SBS 2003

This server was originally setup with RAID 1 mirrored drives (OS c drive), and a RAID 5 array with 3 drives (data).

The c: drive mirrored Array A00-00 failed.   Data drive array shows "optimal" and appears fine from the controller management.

I have now installed 2 new drives, created a new RAID 1 Array A00-00 mirroring the 2 drives and installed the Operating System to this new partition. After booting to my newly installed partition and operating system I expected to see my RAID 5 Array and data. But I am not seeing them.

The OS shows the PERC driver is installed (default).  The mirror array is fine.  Just no data array.  I have a PERC Windows RAID driver that may or may not be a solution, but want to be certain it won't adversely affect the data array.

Dell 2800 Poweredge server with PERC RAID controller. Windows server 2003 SBS.

Note: This is not critical.  Data is backed up. This server is old, the software is old. It's being retired and the data is being moved to a new setup. The data on the partitions is backed up with very small exception so worst case, it is not critical. I would like to recover these partitions simply because it would be better to work with last used data than a backup that might miss a few changed documents.

RE: Array not being recognized within Windows SBS 2003

Since this is a PE2800, I am going to assume that you have a Perc 4 RAID controller installed.  Enter the Ctrl -M bios, and "retag" your RAID 5 array, basically recreating it. Do not initialize it, or it will delete your data!   Restart the server, then check for your data array. When you replaced your RAID 1, it may have lost the config for the data array.

Does your RAID 5 still show in the CTRL-M utility? If so, then don't retag. Do you see it in Disk Management?

The RAID 5 Array still shows in the CTRL-M utility and shows "optimal".

It does not show in Disk Management.

RE: Array not being recognized within Windows SBS 2003

Hi Geoff,  If you look to this thread you will see where "theflash1932" recommends against "retag" if I can see the array in the Ctrl-M bios.   Can you help me understand which is correct?

RE: Array not being recognized within Windows SBS 2003

Let me help:

A retag is a recovery option used when multiple drives have lost their configuration.  It is done by configuring RAID, without initializing the array ... this simply tags each drive in the array with its position in the array so the controller can attempt to ready array data from all relevant drives.  It can ONLY be performed on drives showing as Ready, NOT Online (you can't "retag" drives in an array that are all already "tagged"; to tag a tagged drive, you would have to first delete the array = risky).

If the array is already optimal/online, then there is nothing more should be needed outside of the OS.

Open Disk Management, Actions, Rescan Disks.

I'm not saying that deleting the array and recreating it (retag) won't fix the link between the controller and the OS, but it should NOT be the first thing you try.

RE: Array not being recognized within Windows SBS 2003

Thank you theflash,  I hope I didn't offend you by referring to your post with Geoff.  I'm just trying to understand better.    I opened Disk Management, Actions, Rescan Disks.  The result was the same.  Just my "C" drive and the cd-rom.    

I have no way of booting to the ctrl-m utility at the moment.  So I can't verify that the RAID 5 array is still "Optimal" and "Online" or I would also do this.  But it was very clearly when I was recreating the mirrored array.   Tomorrow at around 9am EST I will be able to confirm.  Is there anything I can do from the OS to further troubleshoot?

No offense taken.  What you describe as having happened is not typical.  Having done this many times, as long as the array is online, it should just show up in the OS.

You can do this all from the OS:

OMSA (OpenManage Server Administrator) can be installed in the OS and will give you direct access to the RAID controller and its drives:

http://ftp.dell.com/FOLDER33998M/1/OM-SrvAdmin-Dell-Web-WIN-6.5.0-2247_A01.10.exe

Download and run to extract, then run C:\Openmanage\windows\setup.exe.  Choose Custom and make sure Storage Management is installed.  Add yourservernameoripaddress:1311 to IE's Intranet Zone.  Open OMSA, Storage, PERC, Virtual Disks ... what is the status/state of your RAID 5?

If the RAID 5 is offline, then you will need to fix it, but "how" you fix it depends on what is wrong with it.

Let us know.

The RAID 5 Array is showing and  is "Ready" under channel 1 when viewing under "configuration".     But when under "Check configuration" and the sub menu "logical drives" it shows only the mirrored drives RAID 1

Boot to CTRL-M, choose Configure, View/Add ... does it prompt you to choose between Disk and NVRAM views?  If so, select Disk View and save on exit.  If not, what does it show for the status of ALL the drives?

"RAID 5 Array is showing and  is "Ready" ... under "configuration""

The "array" is showing as Ready or the drives are showing as Ready?
