CMMVC9290E The mkarray command failed because -level raid5 and raid6 are not supported by this IO group.

Explanation

This error occurs because the hardware for the I/O group does not support the specified RAID level.

On FlashSystem 9100, FlashSystem 9200, and Storwize® V7000 2076-724, the mkarray command can create only RAID 10 arrays. Use the mkdistributedarray command to create RAID 5 or RAID 6 arrays.
