We wan't to upgrade a AutoRaid Model 12H with some new Disk's.
At the Moment we have installed 8 times 9,1 GB Disk in our Array.
We wan't to add 4 times 18 GB to the Array.
The Backround to this Upgrade is, that the AutoRaid handles all Data, configured LUN'S (capacity smaler than 50% from the whole Disk Space) in Raid 0/1. Now we had create a new LUN in the Array, the Array did a balance and will now run in RAID 5. (Because we now have a used Disk capacity bigger than 50%).
The Question is now: Will the AutoRaid automaticly switch back to RAID 0/1 after including the new Disk's (We had set the Autoinclude Disk Option to true).
Thank's for your help
Solved! Go to Solution.

Solutionthe Diskarray will bring back the data in Raid 1/0 but only the data which are rewrite or be new written on the disk. The total performance of the diskarray rise because of bigger 1/0 space. The read performance from RAID 5 and RAID 0/1 is the same.
The diskarray has table were the static of data use is stored and the diskarray switch the DATA back from RAID 5 to RAID 1/0 but this take time the diskarray make this process in the background.
