SO i have to replace the DIsk at slot E0 .. which is in RAID5 with other 4 disks ..
Can anyone give me the steps on how to replace the disk & rebuild the RAID5 ..
Can this be done through the "hparray" utility .. i searched its man pages .. & tried to start "ARMServer" deamon .. but its not starting..
Thanks in advance ..
Points assured ..

Re: Replacing disk in a C2300 Disk Array
There are totaly four LUNS configured ..
LUN0(16.8gb)-(Raid5) 5 x 4.2 GB Disks
LUN1(12.6gb)-(Raid5) 4 x 4.2 GB Disks
LUN2(16.8gb)-(Raid5) 5 x 4.2 GB Disks
LUN3(16.8gb)-(Raid5) 5 x 4.2 GB Disks
Total 19 disks in the whole array.
Now this LUN2.. shown below indicates a "?" for the 5th Disk.. which needs to be replaced..
2 A/A * R/- Off RAID-5 C2300WDR5 16.8gb 512
A0 /A0 IBM DCHS04F CLAR04 4.2gb
B0 /B0 IBM DCHS04F CLAR04 4.2gb
C0 /C0 IBM DCHS04F CLAR04 4.2gb
D0 /D0 IBM DCHS04F CLAR04 4.2gb
E0 /? IBM DCHS04F CLAR04 4.2gb
I searched in HP site .. but dont find any details of this OLD Array...

Re: Replacing disk in a C2300 Disk Array
I can't read it.
Normally you should only swap the disk - that's it.
For more info search the forum for "nike disk array".
Hope this helps!

Torsten.

Re: Replacing disk in a C2300 Disk Array
The column header Fru/BS means Disk FRU/FRU-bind-slot.
If you replace the disk, the rebuild will start automatically.
Hope this helps!

Torsten.

Re: Replacing disk in a C2300 Disk Array
This disk is a 4.2 GB SE-SCSI .. which means not hotswappable .. so i have to poweroff before replacing it ?
SO to replace the drive .. i need to ..
1) shutdown the server ..
2) poweroff the Array
3) Then replace the DIsk.
4) Poweron the Array.. ( It should automaticaly start rebuilding the Raid5 Lun ..)
5) poweron the server ..
Does this step look Good ?

Re: Replacing disk in a C2300 Disk Array
You mean to say .. we can "Hot Swap" the disk while the Array & Server are UP & running ...
Iam little confused .. because when i searched the disk model - DCHS04F ..in sites .. it shows as a Single ended 50 pin Drive .. which i think is not hot swappable ..
