Using zFS in a shared file system environment

zFS supports a shared file system capability in a multisystem sysplex environment. The term shared file system environment refers to a sysplex that has a specification of SYSPLEX(YES) in the BPXPRMxx parmlib member. That is, users in a sysplex can access zFS data that is owned by another system in the sysplex. For full sysplex support, zFS must be running on all systems in the sysplex in a shared file system environment.
