IMPORTANT:
•
Under the LDEV tab, you can also view the associated RAID Group for an LDEV. This data helps
determine if more than one LDEV is contributing to a RAID Group activity.
• If the LDEV is a LUSE Master, the details of individual LDEVs are considered for the busiest com-
ponents and not the sum of all the individual LDEVs.
The LDEV response time components, AVERAGE READ RESPONSE, MAXIMUM READ RESPONSE,
AVERAGE WRITE RESPONSE, and MAXIMUM WRITE RESPONSE, are measured in milliseconds.
Click an LDEV ID or RAID group name to view the performance graphs for all the associated metrics
in a chart window. To know more about charts, see “
Plotting charts ” on page 262.
