Recover BSDS from Global VCAT

The BSDS mirrors information that is stored in the Global VCAT. You can use an intact Global VCAT to recover a damaged BSDS data set. Mirroring the Global VCAT lets you restore the BSDS to a state that is more consistent with the information stored in the tape management database.

Follow these steps:

1. Bring down all the CA Vtape subsystems that are part of the CA Vtape complex sharing the BSDS you want to recover.
2. Customize and submit the RECBSDS member from the HLQ.CCUUJCL library. The job follows these steps:
   1. Deletes the old BSDS.
   2. Defines a new BSDS using the Global VCAT as a model.
   3. REPROs the Global VCAT into the new BSDS.
3. Start one CA Vtape subsystem in the CA Vtape complex and execute the console command SVTn D A. This command displays the correct scratch totals and devices.
4. Start the remaining CA Vtape subsystems in the CA Vtape complex.
