Oh, and forgot to mention, change your mount statement
MOUNT FILESYSTEM('USER.TOOLS')
TYPE(ZFS)
MODE(read) UNMOUNT
MOUNTPOINT('/shared/tools')

Subject: RE: Sysplex File System Sharing with Mountpoints Containing Symlinks
Is filesystem USER.TOOLS part of the z/OS maintained filesystem? Sounds like
in BPXPRMxx you have VERSION set to Z1D on one system, and Z21 on another. If
this filesystem is NOT part of z/OS maintained filesystems, then you can
1) Create a new directory entry in your SYSPLEX ROOT filesystem called
something like /shared/tools
2) In your versioned filesystems, remve the directory /usr/local, and replace
it with a symbolic link like ln -s /shared/tools /usr/local
Then both systems will resolve the directory to the same location. With
shared file systems in z/OS unix, a physical filesystem can only be mounted
once, period.

Subject: Sysplex File System Sharing with Mountpoints Containing Symlinks
I'm testing the sharing of a zFS file system between sysplex'd z/OS 2.1 and
z/OS 1.13 systems. The file system is to be mounted at a mountpoint that
contains a symlink containing $VERSION in its definition. That is, the
mountpoint is '/usr/local' but '/usr' is a symlink defined as '$VERSION/usr'.
On the z/OS 2.1 system, this mountpoint resolves to '/Z21/usr/local'. On the
z/OS 1.13 system, it resolves to '/Z1D/usr/local'.
When the z/OS 2.1 system is IPL'd first, the file system successfully mounts at
'/Z21/usr/local'. When the z/OS
1.13 system is IPL'd second, the mount is refused with message:
BPXF237I FILE SYSTEM USER.TOOLS WAS ALREADY MOUNTED ON PATHNAME /Z21/usr/local.
How does one make the USERS.TOOLS file system available to the z/OS 1.13 at
/usr/local (which resolves to /Z1D/usr/local)?
Configuration:
BPXPRMxx - SYSPLEX(YES)
IOEPRMxx - sysplex=filesys and sysplex_filesys_sharemode=NORWSHARE
Mount command:
MOUNT FILESYSTEM('USER.TOOLS')
TYPE(ZFS)
MODE(read) UNMOUNT
MOUNTPOINT('/usr/local')
