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!

mkqdisk(8)						      Quorum Disk Management							mkqdisk(8)

NAME
mkqdisk - Cluster Quorum Disk Utility WARNING
Use of this command can cause the cluster to malfunction. SYNOPSIS
mkqdisk [-?|-h] | [-L] | [-f label] [-c device -l label] [-d [-d ...]] DESCRIPTION
The mkqdisk command is used to create a new quorum disk or display existing quorum disks accessible from a given cluster node. OPTIONS
-c device -l label Initialize a new cluster quorum disk. This will destroy all data on the given device. If a cluster is currently using that device as a quorum disk, the entire cluster will malfunction. Do not run this on an active cluster when qdiskd is running. Only one device on the SAN should ever have the given label; using multiple different devices is currently not supported (it is expected a RAID array is used for quorum disk redundancy). The label can be any textual string up to 127 characters - and is therefore enough space to hold a UUID created with uuidgen(1). -f label Find the cluster quorum disk with the given label and display information about it. -L Display information on all accessible cluster quorum disks. -d Increase debugging level. Specify multiple times for more information. Currently, specifying more than twice has no effect. SEE ALSO
