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.

IOEZ00559I zFS kernel: Initializing z/OS File System
Version 02.01.00 Service Level 0000000 - HZFS410.
Created on Wed Mar 20 16:05:20 EDT 2013. 
Address space asid x45

Alternatively, you can issue the MODIFY ZFS,QUERY,LEVEL operator command and look for the following message:

IOEZ00639I zFS kernel: z/OS File System
Version 02.01.00 Service Level 0000000 - HZFS410.
Created on Wed Mar 20 16:05:20 EDT 2013. 
sysplex(filesys,norwshare) 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 and 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:

zfsadm -level

IOEZ00020I zfsadm: z/OS File System
Version 02.01.00 Service Level 0000000 - HZFS410.
