Try the following procedures in the listed sequence until all systems can access the file system. After each procedure, use the D OMVS,F system command to check the file system status.
Procedure 1: Issue the MODIFY BPXOINIT,FILESYS=RESYNC system command on any system.
Procedure 2: Issue the MODIFY BPXOINIT,FILESYS=FIX system command. Resolve any problems that FIX processing identifies. If FIX processing unmounts the file system, mount the file system again.
Procedure 3: Issue the TSO UNMOUNT command (or equivalent shell /usr/sbin/unmount command) to unmount the file system. If the UNMOUNT fails, even when you specify the FORCE parameter, continue with the next recovery procedure. Otherwise, after the command unmounts the file system, mount the file system again.
Procedure 4: Issue the MODIFY BPXOINIT,FILESYS=UNMOUNT,FILESYSTEM=file system name system command to unmount the file system. Once the unmount completes, mount the file system again.
