Optimizing volumes used by the IMS system

The IMS Subsystem section lists all the volumes used by the specified IMS environment. You can use this section to address issues such as data sets other than IMS data sets residing on a volume.

The volumes are displayed in various ISPF default colors, depending on the status of the volume.
Note: Your colors might be different if you have changed your ISPF default colors.
Dark blue
Volume is optimal.
Light blue
The volume contains data other than IMS data.
Pink
Both log and database data reside on the volume.
Red
The volume cannot be backed up by IMS Recovery Expert.
