The Host Groups category comprises of ports, RAID groups, LDEVs, and MP blades configured to

LDEV belonging to a host group is also displayed beside that individual host group.
The MP Blades component type displays the individual MP blades associated with the host group. At
this level, you can view the overall utilization of all the MP blades. Further, the utilization of each MP
blade is displayed at the individual MP blade level.
For description of the Ports, RAID Groups, and LDEVs component types, see 'Host Groups navigation
path – For the XP disk arrays'.
In the above mentioned selections, the LDEVs are displayed in the descending order, where the
maximum utilized LDEV is displayed first followed by the subsequent, and least utilized LDEVs.
