6.4 IBM Tivoli Storage Resource Manager top 10 reports
After analyzing typical customer scenarios, we have compiled the following list of “Top 10
reports” which we recommend running regularly for best practices:
򐂰 ESS used and free storage
򐂰 ESS attached hosts report
򐂰 Computer Uptime
򐂰 Growth in storage used and number of files
򐂰 Incremental backup trends
򐂰 Database reports against DBMS size
򐂰 Database Instance storage report
򐂰 Database reports size by instance and by computer
򐂰 Locate the LUN on which a database is allocated
򐂰 Finding important files on your systems
6.4.1 ESS used and free storage
This report shows the free and used storage on an ESS system. To generate this filesystem
logical view report, navigate
IBM Tivoli SRM -> Reporting -> Storage Subsystem ->
Computer Views -> By Filesystem/Logical Volumes
. Select the computers to report on,
and select
Disks from the pull-down Relate Filesystems/Logical Volumes To as in
Figure 6-98.
Note: For demonstration purposes, we have reduced some of the fields in the reports.

Click Generate Report. The report is shown in Figure 6-99. Various columns are displayed:
򐂰 Storage Subsystem
򐂰 Storage Subsystem Type
򐂰 Manufacturer
򐂰 Model
򐂰 Serial Number
򐂰 Computer
򐂰 Filesystem/Logical Volume Path
򐂰 Capacity
򐂰 Free Space
򐂰 Physical Allocation

This report provides quick answers to how much space on the ESS is allocated to each
filesystem.
Select
LUNs this time from the pull-down in Figure 6-98. The report in Figure 6-101 shows
the LUN to host mapping for the ESS, which filesystem is associated with each LUN, and the
free space.

6.4.2 ESS attached hosts report
This report shows which systems are using storage on an ESS. This is useful when ESS
maintenance is applied so that the administrators of affected systems can be informed.
To generate this report, select
IBM Tivoli SRM -> Reporting -> Storage Subsystem ->
Computer Views -> By Computer
tree. We have selected all computers as in Figure 6-102.

Note you can sort the report on a different column heading by clicking on it. The current sort
field is indicated by the small pointer next to the field name. Clicking again in the same
column reverses the sort order.
6.4.3 Computer Uptime reporting
Uptime is an important IT metric in the enterprise. To generate a Computer Uptime report,
select
IBM Tivoli SRM -> Reporting -> Availability -> Computer Uptime -> by Computer.
Select the computers of interest, and a date range (optional), and click Generate Report, as
shown in Figure 6-104.

Figure 6-104 Computer Uptime report selection
For each computer, percent availability, number of reboots, total down time, and average
downtime is given, as in Figure 6-105 shows the selection. The default sort order is by
descending Total Down Time.

You can also display this information graphically, by selecting the pie chart icon at the top of
the report, as shown in Figure 6-106.
