shows an overview of caching activity at the subsystem level
This report gives you a general idea of how your cache subsystems are performing, and provides information about where to look for specific performance problems. It consists of a summary line of information for each cache subsystem and for the most active devices (activity by total I/O rate and by DASD I/O rate).
shows detail information about every cache subsystem and an overview of activity on each subsystem’s attached DASD devices
For each subsystem, the report contains one page of detailed subsystem information, plus one or more pages of device information consisting of a summary line of information for each device. Additionally, if applicable, there is detail information about RAID rank activity in the subsystem.
contains detailed information about every cache subsystem and every logical DASD device attached to a subsystem
For each cache subsystem, this report has one page of detailed subsystem information, and one or more pages of detailed device information, one device per page. The fields in this report are similar to those in the Cache Subsystem Activity report, except that this report shows the data for one particular device rather than for a subsystem.
Important
This report can be quite voluminous, so BMC Software suggests that you request it only for specific devices or ranges, or when troubleshooting cache subsystem problems.
Ordering and filtering: The reports in this table can be ordered and filtered in different ways, so your report might not look exactly like the sample reports shown on the next few pages.
