RAID members need to be included at the same enclosure
which means you need to create array in the same
enclosure. If RAID members are created from two or
more different enclosures, there would be some risks
(for example: if a mini-SAS cable gets problem, more
RAID members will be lost, volume sets belong to this
Array may be failed. Shutdown RAID and JBOD to fix
problem, after that, turn on JBOD and RAID system
again and controller will get array back, but in some
case it may not get the array back)
