• CU group. For mainframe system volumes, the arrays support a maximum of 65,280 LDEVs, and
each CU controls up to 256 LDEVs. The CUs are controlled as a group of 64. This group is called
a CU group. Up to 16,384 LDEVs belong to each CU group. CU groups are numbered from
0 to 3. Table 3 lists the CU groups, terms displayed for the CU groups on the XP Remote Web
Console main pane, and the CU numbers and LDEV numbers for each CU group.
NOTE:
For open system volumes, the arrays support a maximum of only 16,384 LDEVs. This means that CU
group 0 is the only available CU group for open system volumes.
