Note: This note explains the following statistics to be displayed in tabs of
Performance Management windows.
The statistics of LUs that are displayed in the Port-LUN tab.
The statistics of volumes that are displayed in the LDEV tab.
In the above tabs, performance statistics of unused volumes are displayed as
hyphens (-), if the range of monitored CUs does not match the range of CUs
used in the disk storage system or registered as external volumes. In addition,
depending on your disk subsystem configuration, the list may display
performance statistics for some volumes and not display performance statistics
for other volumes.
To correctly display performance statistics, you must specify CUs to be
monitored as follows:
To display performance statistics of a LUSE volume in the Port-LUN tab, you
must specify all volumes that make up the LUSE volume as the monitoring
targets.
To display performance statistics of parity group to be displayed in the LDEV
tab, you must specify all volumes that belong to the parity group as the
monitoring target.
