Всем спасибо!!!
P.S.

Note:

1. Systems with IOAs released before V5R2 of OS/400®, the minimum number of disk units in a parity set is 4. The maximum number of disk units in a parity set is 10.
2. Systems with IOAs released after V5R2 can have a minimum number of 3 disk units in a parity set. The maximum number of disk units in a parity set is 18.

This table shows how many disk units store parity data within a RAID 5 parity set that is connected to a SCSI IOA.

4-7 4
8-15 8
16-18 16

All of the disk units in a parity set with a SAS connection contain parity data.
