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. Start of change

Alternatively, you can issue the MODIFY ZFS,QUERY,LEVEL operator command and look for the following message: Start of change
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) 
End of change

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: Start of change
IOEZ00020I zfsadm: z/OS    zFS                   
Version 02.02.00 Service Level 0000000 - HZFS420.
