Determining file system status

To determine if zFS is currently active, use the following steps:

If the BPXF032D message is outstanding, zFS is not active.
If the operator command D A,ZFS says zFS is not found, zFS is not active.
If the operator command D A,ZFS gives the zFS address space information, zFS is active.

For information about how to identify the file system owner, see Determining the file system owner. To display zFS internal restart information, issue the MODIFY ZFS,QUERY,STATUS operator command.

Beginning in z/OS® V1R11, you can issue D OMVS,P to display the state of the PFS, including the start or exit timestamp. Message BPXO068I returns the PFS in one of the following possible states:

A: Active; the timestamp is the start time of the PFS.
I: Inactive. When the PFS is inactive with no timestamp, the PFS address space has not yet started. When the PFS is inactive with timestamp, the PFS has stop at that time.
S: Stopped; it is waiting for a reply of R to restart or I to terminate the PFS.
U: Unavailable.
