SAN Disk w/o Cluster

Scenario:

I've got 2 M5000's connected to a 9985 SAN storage array. I have configured the SAN disks with stmsboot, format and newfs. I can access the same SAN space from both systems. I have created files from both systems on the SAN space.

Question:

Why can't I see the file created with "SystemA" from "SystemB"?

SystemA:
Code:
root@SystemA# df -h
Filesystem             size   used  avail capacity  Mounted on
...
/dev/dsk/c6t60060E80144380000001438000000342d0s3

Any help is greatly appreciated!

SYSTEMD-VOLATILE-ROOT.SERVICE(8)			   systemd-volatile-root.service			  SYSTEMD-VOLATILE-ROOT.SERVICE(8)

NAME
systemd-volatile-root.service, systemd-volatile-root - Make the root file system volatile SYNOPSIS
systemd-volatile-root.service /lib/systemd/systemd-volatile-root DESCRIPTION
systemd-volatile-root.service is a service that replaces the root directory with a volatile memory file system ("tmpfs"), mounting the original (non-volatile) /usr inside it read-only. This way, vendor data from /usr is available as usual, but all configuration data in /etc, all state data in /var and all other resources stored directly under the root directory are reset on boot and lost at shutdown, enabling fully stateless systems. This service is only enabled if full volatile mode is selected, for example by specifying "systemd.volatile=yes" on the kernel command line. This service runs only in the initial RAM disk ("initrd"), before the system transitions to the host's root directory. Note that this service is not used if "systemd.volatile=state" is used, as in that mode the root directory is non-volatile. SEE ALSO
