Hardware:
PE 1750, Perc 4/Di RAID Motherboard driver, 1 system SCSI drive RAID 0.
Just purchased 2nd identical SCSI drive; with Array Manager is it possible to add 2nd hd and migrate primary single RAID 0 to (2) drive RAID 1 ? Without losing data or having to wipe first drive and re-initialize?
Shut the server down, add the new drive then reboot into the operating system. In array manager, right click on the virtual disk and choose add member. It should present both disks. Select both and select RAID 1. This should create a hardware mirror with the two drives. Below is a link that may help.
Open Manage should work for this and is the newer version of Array manager, however I would use at least version 5.5. Just make sure you perform a custom install of Open Manage and ensure Storage is selected to install. I included a link below to a video walk through for performing a reconfigure in Open Manage by using the storage serices.
I am looking to do the same thing with a CERC 1.5/6h. Will I able able to go from a single RAID0 to a 2 drive RAID1 without wiping the OS on the existing RAID0 drive? Thanks, Diego
Very informative link, thank you. The table is very clear cut if I had a CERC ATA/100 with line two showing clearly RAID0 to RAID1 is possible. However it seems there is an caveat with the CERC 1.5 and it worries me a bit. It seems to say that I can go to RAID1 from a concatenated disk but not from a RAID0. The note at the bottom says:
" You can create a concatenated virtual disk by performing a "Split Mirror" or an "Unmirror" on a RAID 1-concatenated virtual disk. After you have done so, however, the resulting concatenated virtual disks cannot be subjected to any further modification. You cannot reconfigure or add disks to the resulting concatenated virtual disks"
Maybe I am reading too much into this but it seems like I need to start out with a "RAID1 concatenated disk". My disk is just a single drive that used to be part of a RAID1, meaning I consider that I don't have a "RAID1-concatenated drive" but merely a "RAID1" disk.
