Host Groups navigation path
The Host Groups category comprises of ports and LDEVs configured to communicate with the individual
host groups. Each individual host group has two main component types, Ports 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 and the LDEVs associated with each port.
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 indi-
vidual LDEV.
• LDEVs displays all the LDEVs that are associated with the individual host group.
The average I/Os for each LDEV belonging to the host group is displayed beside the individual
LDEV.
In both 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 > LDEVs (component
type) > Individual LDEVs.
Host Groups > Individual host groups > LDEVs (component type) > Individual LDEVs.
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 also
displayed beside the port ID.
