group further displays all the physical LDEVs and pool LDEV which may and may not be
associated with the selected host group.
•
LDEVs displays all the LDEVs that are associated with the individual host group. PVols are also
displayed under LDEVs node. A label (P-Vol) is added to differentiate PVols from other LDEVs.
Further, the PVols have the following components, SVol, Pools, Pool LDEVs, and Raid Groups.
◦
SVol displays the individual SVols that are associated with the selected PVol.
◦
Pools displays the individual pools associated with the PVol.
◦
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 or FCoE (applicable only for P9000 disk arrays) is displayed beside
the port ID.
