Controlling CM

"Automatic" and the installed "CM#x CPU#y" in normal status are displayed as options.
Select "Automatic" for normal operations. When "Automatic" is selected, the CM that is
to be assigned is determined by the RAID group number. For the ETERNUS DX80 S2/
DX90 S2 or the ETERNUS DX410 S2, "CM#0 CPU#0" is assigned for the RAID groups
with even numbers. For RAID groups with odd numbers, "CM#1 CPU#0" is assigned.
For the ETERNUS DX440 S2, "CM#0 CPU#0" is assigned for RAID groups if the RAID
group number is dividable by "4" (the number of CM-CPUs). If the remainder is "1",
"CM#1 CPU#1" is assigned. If the remainder is "2", "CM#1 CPU#0" is assigned. If the
remainder is "3", "CM#0 CPU#1" is assigned.
