Restoring Mounted User-Defined File Systems (UDFS) with BRMS
Beginning at IBM i 6.1, if a save operation includes objects from a mounted user-defined file system (UDFS), file system information is saved. You can restore a mounted UDFS by specifying the RBDMFS(*UDFS) parameter on the RST command. The RBDMFS parameter rebuilds the mounted file system during the restore operation.
Specifically, there is no indication in the recovery report that there are mounted UDFSs to recover
BRMS automatically specifies RBDMFS(*UDFS) when restoring the IFS via BRMS.
