HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

Viewing Matrix state
The exdsmgr show matrix command shows the state of the Matrix.
The exdsmgr show matrix all command shows cluster state information that could help debug
a system. For example, the all option shows export path errors that would not have generated
an automatic alert otherwise, and would not have been visible with the show matrix command
alone.
