We would like to be able to mirror storage across more than two physical DASD units per logical storage unit.
Mirroring currently only supports two DASD units, so it only has protection against a single DASD device failure in the pair. While the probability of the mirrored unit failing is low, the rebuild process puts extreme load on the remaining unit and can take a very long time with large modern drives. Maintenance to IOAs or expansion EMMs can also cause a loss of mirroring across a large number of units at once, increase exposure to a failure.
While RAID-6 supports two-drive redundancy, RAID is not an acceptable solution to our organization as we have had several instances in the past where an IOA, expansion frame, or even a single failed DASD unit has prevented access to the entire array, resulting in a system halt and/or corrupted data..
