[cisco-voip] RAID1 disk mirroring

[Ryan Ratliff]

Not supported by HP or Cisco as cips stated.

That said:
1. The server definitely won't boot and I wouldn't expect either disk to be usable if you put them into the wrong slots.
2. Depending on the raid controller settings on the second server and the hardware between both servers it could do anything from boot normally to corrupt both disks.

I'd highly encourage you to test both scenarios with data on the hard disks you don't mind losing.

For Cisco MCS server this procedure is officially not supported…
 
1.       The system will boot from the primary disk
2.       In the new server the system will boot but you might have issues with (raid) drivers in the os

Our normal disk swap procedure is
1. power off the server
2. pull disk 1 out
3. if upgrade fails, power off the server again, pull out disk 0, and put disk 1 back to the original tray, power on the server and then put disk 0 back to tray0

Curious to know
1. what is going to happen if I pull out both disks and swap the disks, disk1 goes to the slot0, disk0 goes to slot1
1. what is going to happen if I pull out both disks and insert them to another server

Thanks in advance.
