EMS Hardware Monitors (HP-UX Only)
With Event Monitoring Service (EMS) you can be alerted to problems as they
occur, allowing you to respond quickly to correct a problem before it impacts
the operation of the array. All operational aspects of the array are monitored.
EMS gives you the flexibility to deliver event notification using a variety of
methods.
EMS is enabled automatically during installation of the CommandView SDM
software, ensuring immediate detection and reporting of array events.
The EMS monitor used for the HP StorageWorks Virtual Array products is the
Remote Monitor. Information on this EMS monitor can be found at the Systems,
Hardware, Diagnostics, and Monitoring section of HP’s Online Documentation
Web site:

Here you can find the Remote Monitor data sheet and a description of the
events generated by the array.
Note On HP-UX systems, SAM may incorrectly identify the VA7110 as
a VA7405.

level, which indicates the impact the event may have on the operation of the
array. The following severity levels are used for all events:
■
Critical - An event that causes host system downtime, or other loss of
service. Host system operation will be affected if the disk system continues
to be used without correction of the problem. Immediate action is required.
■
Serious - An event that may cause, host system downtime, or other loss of
service if left uncorrected. Host system and hardware operation may be
adversely affected. The problem needs repair as soon as possible.
■
Major Warning - An event that could escalate to a serious condition if not
corrected. Host system operation should not be affected and normal use of
the disk system can continue. Repair is needed but at a convenient time.
■
Minor Warning - An event that will not likely escalate to a severe condition
if left uncorrected. Host system operation will not be interrupted and normal
