Recover a Local VCAT

The Local VCAT contains data that is loaded from the parmlib or is transient in nature. If a Local VCAT is damaged or lost, create a new one by customizing and executing the DEFVCAT job found in HLQ.CCUUJCL.

After the new Local VCAT has been created and the CA Vtape Subsystem has been started, issue the SVTn SET MAXDRIVES=nn console command to establish a limit on the number of physical tape drives used by the Backstore Engine. If you need to deactivate the High-Speed Open option, issue the SVTn SET HSOPEN=OFF console command.

Updating the parmlib VTSCMDS member with these console commands will ensure that the appropriate limits and features are established and activated whenever CA Vtape is started.

Note: For information concerning the VTSCMDS parmlib member, see the chapter "The Parameter Library (PARMLIB)" in the Configuration Guide.
