Re: Change disk with RAID 1

Make sure you have latest utility and Driver
http://h18023.www1.hp.com/support/files/server/us/download/23074.html

Be aware of problem, previously experienced with G2
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=PSD_EL011003_CW01

If you read carefully it say's ...
Server may become inaccessible ...
So it's possibly however you need to have a good backup and proceed on your own risk

In case failure with disk manager or third party SW to utilize new space, make sure you would be able to restore from backup
You might want to break RAID and do all of that with one and after recover to second.

Use Ghost or other utility

Re: Change disk with RAID 1

The system support has capacity for four ATA hard drives
Primary channel 40+40 (0,1) and second channel 80+80 (0,1)

sorry, kov. I wasn´t here

Today, there are two disk. One is Device 0 in the primary controller and the other is Device 0 in the secondary controller.

In the link you send (pag 30) is represented by 1 and 2.

Re: Change disk with RAID 1

I send attachment please see for clarification

In the PDF they listed by device 0,0,1,1

the way how it configured now, it will work, however it will complicate with: transfers, recovery and performance if you have second set of HDD
