    RAID1 Help

    Bummer - I just posted a similar thing but I don't have a failed drive. You can probably do this through the megacli also BUT I'm unfamiliar with megacli to do what WE want to do. The problem looks like it's not the exact same drive type and it sees a slight difference in drive geometry. I would gather if you buy the EXACT same drive what you want to do would work BUT if you don't...you need to do the setup wizard (which I can't do because the server is 4 hours away at the moment) OR figure out the megacli method to shove that drive in regardless of the drive geometry - it is a larger disk by a hair so it would work.
  2. LSI's no help and niether is IBM on this matter. I have a 4 drive RAID5 that consists of 4 - 250 gig hard drives (750 gb total size). What I'd like to do is "upgrade" the configuration to 4 - 500 gig hard drives. Unfortunately I can't find anything online about this. I know what I want to do and I know it CAN be done because I've done this on other systems like a Dell SAN. What I'd like to do is: RAID5: Disk0 - 250 -- Disk1 - 250 -- Disk2 - 250 -- Disk3 - 250 -- Step 1: * Replace 1 physical disk > Rebuild Array on the added disk (yes, I know it will ONLY rebuild on the 250 and that's OK) RAID5: Disk0 - 250 -- Disk1 - 250 -- Disk2 - 250 -- Disk3 - 500 -- > Rebuild > wait till done Step 2: * Replace 1 more physical disk > Rebuild Array on the added disk RAID5: Disk0 - 250 -- Disk1 - 250 -- Disk2 - 500 -- Disk3 - 500 -- > Rebuild > wait till done Step 3: * Replace 1 more physical disk > Rebuild Array on the added disk RAID5: Disk0 - 250 -- Disk1 - 500 -- Disk2 - 500 -- Disk3 - 500 -- > Rebuild > wait till done Step 4: * Replace 1 more physical disk > Rebuild Array on the added disk RAID5: Disk0 - 500 -- Disk1 - 500 -- Disk2 - 500 -- Disk3 - 500 -- > Rebuild > wait till done DONE! Then I should be able to go into the disk manager of the OS and "expand" the volume! I should have 1.5 TB with the upgrade. The "problem" is - if I take out a disk, slap a 500 gb one in the megaraid gui doesn't have any option OTHER than making it a system "hot spare". IBM obviously struggles with the gui or maybe LSI isn't making the options available. Anyway - anyone have any insight on megacli options for me to accomplish the task? Yes - I do have a FULL BACKUP of the volume just in case ;-) Thanks! Edit: Found another good explanation of what I want to do here: https://www.redhat.com/archives/rhelv6-list/2013-September/msg00011.html Unfortunately, nobody seems to post anything online in a clear way that works! :-(
