SMB_NO_ZFS_SYSPLEX

Description:

Determines if the DFS/SMB File Server is running in a sysplex and if so, determines if any member of the sysplex is running zFS sysplex aware.

Reason for check:

In a sysplex environment, exportation of a zFS file system and subsequent sharing by the DFS/SMB server can only take place on the system that owns the file system and is not running zFS sysplex aware. Beginning with z/OS® V1R11, the SMB server cannot export zFS read/write file systems when zFS is running sysplex-aware on either:

The same system where the SMB server is running
The system that owns the zFS file system

If you want to export zFS file systems using the SMB server, you must configure zFS as non-sysplex aware (by specifying sysplex=off in the zFS IOEFSPRM configuration file).

z/OS releases the check applies to:

z/OS V1R11 and later.

User override of IBM® values:

The following shows the default keywords for the check, which you can override on either a POLICY statement in the HZSPRMxx parmlib member or on a MODIFY command. This statement may be copied and modified to override the check defaults:
