SMS Storage Class

CA Vtape requires that a storage class with the following characteristics be defined:

Performance Objectives 
  Direct Millisecond Response . . . :
  Direct Bias . . . . . . . . . . . :
  Sequential Millisecond Response . :
  Sequential Bias . . . . . . . . . :
  Initial Access Response Seconds . :
  Sustained Data Rate (MB/sec)  . . : 0 
Availability. . . . . . . . . . . . : N for NOPREF 
Accessibility . . . . . . . . . . . : N for NOPREF 
  Backup  . . . . . . . . . . . . . :
  Versioning  . . . . . . . . . . . : 
Guaranteed Space . . . . . . . . . .: N for NO 
Guaranteed Synchronous Write . . . .: N for NO 
Multi-Tiered SGs . . . . . . . . . .: 
Parallel Access Volume Capability  .: N for NOPREF 
Cache Set Name . . . . . . . . . . .: 
CF Direct Weight . . . . . . . . . .: 
CF Sequential Weight . . . . . . . .:

The other storage class characteristics can be left at their default value or blank.

Note: To allow CA Vtape to release unused space, the LDSs must not be multistriped. This means that the defined storage class must have a Sustained Data Rate set to zero and Guaranteed Space set to no.
