Determining service levels
You can determine the service level of the zFS physical file system
by examining the messages that occur on the operator's console when
zFS initializes.

Version 02.02.00 Service Level 0000000 - HZFS420.

Address space asid x44
Alternatively, you can issue the MODIFY ZFS,QUERY,LEVEL operator
command and look for the following message:
IOEZ00639I zFS kernel: z/OS zFS
Version 02.02.00 Service Level 0000000 - HZFS420.
Created on Fri Mar 20 09:26:25 EDT 2015.
sysplex(filesys,rwshare) interface(4)
In a z/OS® V1R13 or later shared file system environment, the sysplex level is (filesys,norwshare) or (filesys,rwshare), depending on the sysplex_filesys_sharemode. The interface is (4).
In addition, you can determine the service level of the zfsadm command
by issuing the -level option of the zfsadm command.
For example:
IOEZ00020I zfsadm: z/OS zFS
Version 02.02.00 Service Level 0000000 - HZFS420.
