Combine 2 logical raid 0 drives to 1 logical raid 1 drive
You can add a disk to an existing array.
In this case, you probably want to delete whatever is on Array C. Add that drive to Array A.
If you do so, the fault-tolerance level of logicaldrive 1 should become RAID 1.
The GUI utility will be easiest for you... but the CLI process will be something like:
controller slot=0 array C delete forced
The add command adds a physical drive or spare to the specified array or logical drive. Adding physical drives is the same as expanding an array.
controller slot=0 array A add drives=1I:1:1
modify [raid=0|1|1adm|1+0|1+0adm|5|50|6|60|?] [stripsize=8|16|32|64|128|256|512|1024|default|?] Migrates the specified logical drive to the desired raid level and/or strip size. The implied units of stripsize are KB. The target can be any valid logical drive.
controller slot=0 logicaldrive 1 modify raid=1 stripsize=default
