Disabling the Automatic Mounting of Volumes
When the EMS Extractor process is stopped, volumes will stop being mounted
automatically. The mount requests will stay pending until a manual load or until the
restarting of the EMS Extractor BBEXT.
If the EMS Extractor is not registered in the Kernel subsystem, simply stop the
process:
TACL> STOP $BBEXT
If the EMS Extractor is registered in the Kernel subsystem, stop it through SCF. If
#BBOXEXT was the registered name:
TACL> SCF ABORT PROCESS $ZZKRN.#BBOXEXT
Enabling the Volume Automatic Mount
When the EMS Extractor is restarted it will process pending mount request before
listening for new ones.
If the EMS Extractor is not registered in the Kernel subsystem, use the provided
sample OBEY file to start it:
TACL> OBEY OEXT
