Hi,
I need to replace a SAS HDDs on rx 2660. The volume groups of which this HDDs belong is mirrored. So after replacing the HDDs do I need to again remirror the volume groups or only need to sync the LV.
Please send me the steps what I need to do.
Regards
Syed

SolutionA quick look to rx2660 User Service Guide tells me it has an optional hardware RAID controller. So the correct procedure will depend on if you have a hardware RAID installed or not.
With hardware RAID, the default is to automatically rebuild the RAID set as soon as the failed disk is replaced. If this behavior is not desired, it is possible to disable auto-rebuild; however, it seems to me most people don't do that.
If this command lists any devices, your system has a hardware RAID installed:
ioscan -kfnd ciss
The device name would be like /dev/cissN, where N is a number. To verify the state of the RAID controller, you would use a command like "sautil /dev/cissN". See "man sautil" for more information.
If you don't have a hardware RAID controller, your mirroring is implemented with MirrorDisk/UX. The MirrorDisk/UX product only mirrors the data inside mirrored LVs, not the EFI partition structure nor the bootloader.
Here is a HP document about dealing with disk failures, known as "When Good Disks go Bad":
http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c01911837/c01911837.pdf
See the step-by-step procedure starting on page 36, titled "Replacing a Mirrored Boot Disk".
