Next, create the file system. You can use the CREAHFS example from SAMPLIB (shown below). The sample file is for HFS, but zFS can also be used.
//CREAHFS EXEC PGM=IEFBR14
//* Allocate a dataset for a USS file system. The space allocated, 250
//* cylinders, corresponds to about 200 MB on a 3390 device.
//HFS DD DSN=SSZ.SRVR6110.HFS,
To mount the file system on /opt/tectia use the MOUNHFS example from SAMPLIB as shown below.
//* REPLY nn,dddd ON THE MACHINE CONSOLE TO ALLOW MOUNT
//MOUNT EXEC PGM=IKJEFT1A,DYNAMNBR=75,TIME=100,REGION=6M
//* Mount the file system on an existing, empty directory
//SYSPRINT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSTERM DD DUMMY
//SYSTSIN DD *
MOUNT FILESYSTEM('SSZ.SRVR6110.HFS') +
Note that mounting the file system causes an operator query that must be responded to. You may want to copy the mount command into the BPXPRMxx member in PARMLIB so that the file system is mounted each time you IPL the system.
