HP Surestore Disk Array 12h - And FC60 Manual page 120

Restriction
The maximum number of clients (Enterprise
Management Window and Array Management
Window open) that can monitor a Direct
managed Storage Array concurrently is eight.
This number assumes that each client is
actively managing the Storage Array and opens
the maximum number of three concurrent
connections to each controller.
You cannot use a system for both cluster and
non-cluster storage.
It is not recommended to use 2100/2100A
QLogic HBA with the SHV2200. Unpredictable
results can occur under certain stress
conditions.

Workaround
None.
This monitoring limit does not apply to clients
managing Storage Arrays through the Host-
Agent software.
The NVSRAM settings must be modified to
support cluster operation. Once the settings
are modified, the array can only be used in a
cluster environment.
Use only model 2200 QLogic HBA in the
Windows environment.
