Host Groups navigation path
In HP XP P9000 Performance Advisor v6.0 and earlier versions, if you configure multiple host
groups with the same name, then all ports associated with that host group are listed under the
common host group.
For the XP disk arrays
The Host Groups category comprises of ports, RAID groups, and LDEVs configured to communicate
with the individual host groups. Each individual host group has three main component types, Ports,
RAID Groups, and LDEVs. The aggregate of the average I/Os from each LDEV belonging to a host
group is also displayed beside that individual host group.
• Ports displays the individual ports associated with the host group.
The aggregate of the average I/Os from each LDEV belonging to a host group through the
port is also displayed beside each individual port ID.
Similarly, the average I/Os for each LDEV associated with the port is displayed beside the
individual LDEV.
• RAID Groups displays the individual RAID groups which contains the LDEVs associated with
the host group. At this level, you can view the overall utilization of the RAID group. Each RAID
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 PVol
snapshot pairs.
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.
