As the needs of your complex change and as new hardware becomes available, you might need to change the storage classes.

Perform the following steps to modify a storage class.

1. Display the Storage Class Application Selection panel (select option 5 from the ISMF Primary Option Menu for storage administrators).

2. Supply values on the Storage Class Application Selection panel:

   CDS Name

   Is the name of the SCDS that contains the storage class you want to change.

   Storage Class Name

   Is the name of the storage class.

   Option

   Select option 4, Alter. This displays the Storage Class Alter panel. This panel contains the same attributes as the Storage Class Define panel. The fields are primed with the information that you entered when you defined the storage class.

   _______________________________________________________________
