Dashboard busiest LDEVs information
You can view the maximum and least X busiest LDEVs associated with the selected Frontend, Cache,
or Backend resource in the LDEV Information section. The maximum and least busiest LDEVs are
decided based on the average read-write response time of LDEVs associated with a port or RAID
group. The number X is configurable, which you can specify on the Threshold Settings screen. In
addition, you can also configure sorting of LDEV records in ascending or descending order. For more
information, see “Specifying LDEV settings” on page 103.
IMPORTANT:
You cannot view the maximum and least X busiest LDEVs for multiple Frontend or Backend resources,
or a combination of resources in these categories.
