1/1ADM/10 for the PMC storage controller might cause the RAID level to increase depending
on the number of the added drives.
•
To migrate RAID 1 to RAID 5, you cannot add drives directly to RAID 1. First migrate RAID 1 to
RAID 0, add drives, and then migrate RAID 0 to RAID 5.
Examples
# Migrate RAID 0 to RAID 5.
[root@localhost ~]# arcconf modify 1 from 0 to 305190 5 0 0 0 1 0 6 0 7
