Cant create additional raid

6 x 300GB (largest available U320 SCSI HDD Capacity) = 1800 GB

2 drives indicates they are RAID 1, which are mirrored. 2 x 36GB = 36GB. This is an industry standard config. If you make any changes you will lose the array making it RAID 0 (no RAID - no longer hot swap), and or the complete loss of OS / data.

Instead make another logical drive for data storage. You need three or four drives to set up as RAID 5, again an industry standard config.

Make sure to back up in all instances. GL

Raid level 5 gives you some redundancy in your raid however it only allows you to lose one hard drive, two hdd lost would not permit to recover from. the parity bit can rebuild one hard drive but not two, sorry your raid might be lost

dear mjabim,

it is possible...

actually raid has formed with hdd lun noand id nos ,

your old raid may formed with 1,2,3 id's

if you are adding these three disks

it will display as a physical dries in your raid bios and also it will not be covered under your old raid

you create one more raid array on your with those new disks

when you are these things , you have to do very carefully ...

for additional info please reply with raid card model for getting info about raid bios

Hi

You would need 4 Hard disk drives in total. you would need to create 2 RAID 0 (striping) and then Mirror them (RAID 1). to elaborate, HDD A&B will be at RAID 0 as well as HDD C&D. after, you would have to Mirror your two RAID 0. (raid 0+1 is also known as raid 5)

Hope this helps.

there must be some key on the startup to enter into the raid menu. And in that raid menu you can create raid .

When your system boots up you should see an option to access your raid controller if not or if your system doesn't see the controller at all you will have to download the utility software from IBM, but you need to be careful any change you make in the configuration of the disks will delete all data on your drives. This is non-recoverable loss. The utility has help and is fairly easy to understand.

You can retrive the data but it will not be stable.You should buy 10k drive

Do a ghost on the first hard drive install ghost on new hard drive and replace, I can provide more details on procedure just ask
