Hi

I just had a Raid 1 failure for one of the disks. Is it difficult to change
the disk? What are the steps involved? Or should I get a professional for
this task?

I have the urge to try it out but afraid I might lose all the data.

Many thanks in advance for any advice.

Hello Richard,

Please describe more how your hardware is and is it a software RAID or with
a RAID controller on the server?

Best regards

Hi Meinolf

Its a hardware, dell power edge. I was thinking if I just open the raid
hardware, take out the degraded disk, put in a new one, reboot, all will be
back to normal?

Hello Richard,

Well, we use HP servers also with hardware controller and if one disk is
broken, we just do it the way you describe in the running server, because
they are hot swappable. Pull out the broken one and insert the new, then
replication starts automatically. Because this can slow down the system,
we do steps like this mostly at the end of a day so that users are not involved
so much.

Best regards

Hello Meinolf

I read somewhere that we should not shut down the server and change the disk
while its running. Should we do it this way?

Thanks again
Richard
 
Try booting with a fault tolerant boot floppy (a fancy name for a floppy
boot disk ;-) ). You will need an ARC path in the boot,ini file that
will point to the second hard disk. http://www.nu2.nu/bootdisk/ntboot/
Note that on Windows 2000 the default location for the Windows
installation is the WINNT folder, so the sample boot.ini file on Bart's
site will have to be adjusted accordingly, example:

[boot loader]
timeout=-1
default=multi(0)disk(0)rdisk(0)partition(1)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="First harddisk, first
partition" /fastdetect
multi(0)disk(0)rdisk(1)partition(1)\WINNT="Second harddisk, first
partition" /fastdetect


If you can boot with the floppy you can backup your data then break the
mirror and replace the failed disk.

Hello Richard,

I don't know the way Dell handles this, maybe use Dell support for this.
But do NOT remove the disk, if it is not hot swappable.

Hi Meinolf

I think I will take your advice, get Dell support for this.

Many thanks
Richard
 
Hi John John

Many thanks for your reply but I think your way is too hot for me to handle.
I think I will let Dell support handle it this time.

Regards
Richard

If you feel uncomfortable doing it yourself that is the wisest thing to do.
