You use this dialog box to issue the DFSMSdss DEFRAG
command to defragment the volumes that you selected in
the Tivoli® Enterprise
Portal.
To learn about the standard capabilities
of a dialog box, see Standard tabs in the dialog boxes of the Storage Toolkit. The
topic includes a link to the Reference
guides for commands that are used in the Storage Toolkit.
The dialog box provides the following options:
- Exclude Datasets qualified by: You can add a qualifier
to exclude data sets. Enter a fully-qualified name or pattern that
identifies the data sets to exclude.
- Fragmentation Index: Specify an integer n. When
fragmentation drops below the value of n, the defragmentation
operation ends. The DFSMSdss facility places a decimal point before
the value that you specify for n, as in these examples:
- If you specify 1, the value becomes .1.
- If you specify 999, the value becomes .999.
- If you specify 001, the value becomes .001.
- Fast Replication: Use the drop-down menu to set your preference
for use of the DFSMSdss fast replication feature. If the Fast
Replication option is blank (the default), fast replication is
not enabled.
- Run as DFSMSdss Administrator: Select this
option to cause the command to run with Administrator authorization
in DFSMSdss. The user ID that you are using
must be authorized as a storage administrator in DFSMSdss.
- Dynamic Allocation: Select this option to cause the command
to use dynamic allocation for the affected data sets.
- Peer-To-Peer Remote Copy for FlashCopy®: Select
this option to specify that a Peer-to-Peer Remote Copy (PPRC) primary
volume is allowed to become a FlashCopy target volume. This
option is ignored when FlashCopy is not used for
defragmentation. RACF authorization might be required for this option.
- Consolidate: Select this option to enable the command to
consolidate multiple extent data sets when possible.
- Write Check: Select this option to enable verification
for the data moved by defragmentation. Verification increases the
time required for the defragmentation operation.
