Re: Changing raid 0+1 to raid 5
system: proliant ML G5
4 hdd 2 logical disks in 2 raid 0+1 array's
is there any way to change this to 2 raid 5 arrays ?
let me clarify: for Raid 5 implementation you need minimum 3 hard drives.
4 hard drives are configured under 2 seperate logical drives with Raid 1 so migrating any of the raid 1 logical drives to Raid 5 require one more disk. But you can not merge two logical drives into one.
So options that you have.
1. delete one logical drive so that other two disks become available to expand the array or migrate it to Raid 5..however, this option may not be feasible if you have data in logical drive which you want to delete.
2. backup everything. delete the existing raid volume and recreate new raid 5 volume with 4 disks.
3. if your logical drives are configured under the same array, add an additional drive to expand the array then you should be able to migrate both the raid 1 volume to Raid 5.
refer ACU guide to understand array expansion.
http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00729544/c00729544.pdf
had all the 4 drives configured under 1 raid 1+0 volume, this would have been easier to migrate it to Raid 5 without adding any drive or any data Loss.
hope this helps,
thanks,
Aftab

Re: Changing raid 0+1 to raid 5
What it takes:
Depend on what you want to do, and what you have done so far, and what controller you have got.
As Manuel write. The Smart Array controllers used in modt Prolaints. Support RAID level migration. Some require a BBWC installed (E and P models).
How is it currently configured?
Beware vendors use different terms.
On the Smart Array:
Array = a number of disk's, that work together. RAID level is not defined.
Logical drive = Logical drives is createt on the Array, it it define the size of the logical disk and the RAID level.
And on the newer Smart Arrays (FW / ACU)
RAID 1+0 using 2 disk = RAID 1. But still named 1+0.
So do you have 2 Arrays holding 1 logical disk RAID 1 (1+0 / 0+1) each?
or 1 Array using all 4 disks, with 2 logical drives. And are the logical drives 2 disk RAID 1+0 (1 / 0+1) or is it 4 disk RAID 1+0 / 0+1?
If you've got 2 Arrays with 1 Lgical drive each.
You must add 1 disk to each array, and migrate it.
Once you have done so you can extend the logical drives to use all capacity.
If you have got 1 array, with 2 RAID "1" logical drives.
It might be that you may need to add 1 disk only to the array. Then migrate both Logical drives.
If you got 1 Array holding 2 RAID 1+0's.
Then you can do a RAID level migration on both logical drives. And then exten both or 1 of the logicl drives.

Re: Changing raid 0+1 to raid 5
thanks for the great replies.
right now i'm having trouble with the raid utils.. trying to get them up and running.
i guess after that, i'll add 2 drives, and add them to the arrays, migrate both arrays to raid 5 and have the best data-safety (besides raid 6).
right now 2 drives failed in the raid 1+0 array resulting in total data-loss :(
never again please ....
i'll be in touch about the progress
