Removing (unconfigured) disks from RAID-5 array?

Hi All,

apparently two 8GB disk that I left unconfigured are not only in the System ASP (as by design), but also part of the (RAID-5) parity protection of 4x 17GB disks.
Why this happened I don't know, let's just call it inexperience :)

I wanted to move the 8GB disks to a User ASP and mirror them, but the system won't let me. I don't really need the 8GB disks, but I think it's better to keep the RAID array 'clean' by using similar sized disks. Maybe this move also changes the RAID-5's status from 'unprotected' to 'protected' ('Display Disk Configuration Status' screen shows ASP 1 as 'unprotected', while all four disks show 'RAID-5/Active'??).


Documentation seems to say that I have to stop parity protection to move the disks to another ASP, but in my world, 'stopping/destroying a RAID array' means 'loosing all data that's on that array'.

My question is: is it possible in i5/OS V5R4 to stop parity protection, move the 8GB disks to another ASP, and enable parity protection on the disks in ASP 1 again, without having to reinstall the LIC/OS again?

Thanks for any info,

Rene,
Holland.
