HP XP Performance Advisor Software - Manual (Page 257)

◦ Pool LDEVs displays the individual LDEVs associated with the Pool.
◦ Raid Groups displays the individual Raid Group associated with the Pool LDEVs.
NOTE: The components SVol, Pools, Pool LDEVs, and Raid Groups are displayed only for PVols.
These components will not be seen if the LDEV is not a PVol.
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.
Following are the component selection path:
•
Host Groups > Individual host groups > Ports (component type) > Individual Ports.
•
Host Groups > Individual host groups > RG(s) (component type) > Individual RAID groups. At
the individual RAID group level, you can view the average utilization of the RAID group by
the associated LDEVs. The utilization shown is not specific to the host group to which the RAID
group belongs. Each RAID group further displays the following:
◦ Individual RAID group > Physical LDEVs (component type) > Individual physical LDEVs.
◦ Individual RAID group > Pool LDEVs (component type) > Individual pool LDEVs.
•
Host Groups > Individual host groups > LDEVs (component type) > Individual LDEVs. At the
individual LDEV level, you can view the corresponding average I/O per second data.
NOTE: The ports and LDEVs can be associated with multiple hosts in a host group.
The port type, such as Fibre, Ficon, Escon, or FCoE (applicable only for P9000 disk arrays) is
displayed beside the port ID.
In the above image, under Host Groups for the XP disk array 10090:
•
Host Groups is the main category. The number (79) indicates the number of host groups
available in that category.
•
SVOL is one of the individual host groups. The number 2413 indicates the aggregate of the
average I/Os from each LDEV belonging to Host Group
