How to replace failed drive in RAID 1(1+0) array in HP DL380 G4

Hello experts,

 

I've a HP DL380 G4 which has 4 disks(2x18.2G and 2x72.8G),the OS is Ubuntu 8.04.3 with OpenVZ(has 10 VM running)

Following are disks info when I do

 

#cat /proc/driver/cciss/cciss0

 

cciss0: HP Smart Array 6i Controller Board ID: 0x40910e11 Firmware Version: 2.58 IRQ: 51 Logical drives: 2 Max sectors: 2048 Current Q depth: 0 Current # commands on controller: 0 Max Q depth since init: 20 Max # commands on controller since init: 53 Max SG entries since init: 31 Sequential access devices: 0

 

cciss/c0d0: 18.20GB RAID 1(1+0)

cciss/c0d1: 72.83GB RAID 1(1+0)

 

 

From the front panel light status, one of 18.2G(15k) disk has failed(which is located at slot 0).

Now I've a replacement disk,which is 72.8G(10k).

My question is :can I just simply remove the broken one(18.2G) from slot 0 and insert this new 72.8G disk? The system will rebuild RAID system?

 

Many thanks!

To persons who have interest for this topic,

 

what I did yesterday is,

 

pull the failed drive(18.2,15K) and pop in a new one(72.8G 10K) without reboot.

 

Followings are output when do command :

 

#hpacuali ctrl all show config

 

Smart Array 6i in Slot 0 (Embedded)

array A (Parallel SCSI, Unused Space: 0 MB)


logicaldrive 1 (17.0 GB, RAID 1, OK)

physicaldrive 2:0 (port 2:id 0 , Parallel SCSI, 72.8 GB, OK)
physicaldrive 2:1 (port 2:id 1 , Parallel SCSI, 18.2 GB, OK)

array B (Parallel SCSI, Unused Space: 0 MB)


logicaldrive 2 (67.8 GB, RAID 1, OK)

physicaldrive 1:2 (port 1:id 2 , Parallel SCSI, 72.8 GB, OK)
physicaldrive 1:3 (port 1:id 3 , Parallel SCSI, 72.8 GB, OK)

 

We lose some disk space and disk speed(which can be ignored),I think.
