HP ProLiant Gen8 Health Agents and EL6.x - cpqHoMibHealthStatusArray has changed to the value: x

Question

I've noticed that my HP ProLiant Gen8 servers report the following message via email to root (or the destination configured in /opt/hp/hp-snmp-agents/cma.conf) upon restart.

Trap-ID=11020

cpqHoMibHealthStatusArray has changed to the value :02 03 02 02 02 02 02 03 02 02 02 02 02 01 01 02
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

or sometimes...

Trap-ID=11020

cpqHoMibHealthStatusArray has changed to the value :02 04 02 02 00 00 02 04 02 02 02 02 02 01 01 02
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

This seems to be unique to the EL6.x and Gen8 combination and happens upon initial boot or the restart of the hp-snmp-agents service. Any ideas on what this output means?

Solution

This is documented. Check out the post at HP Blogs called "HP ProLiant Gen8 Agentless Management Overview" -- the relevant portion is copied below. Basically, each array element is the status of a different monitored component.

The definition of “cpqHoMibHealthStatusArray”:

  cpqHoMibHealthStatusArray OBJECT-TYPE
      SYNTAX  OCTET STRING (SIZE (1..256))
      ACCESS  read-only
      STATUS  mandatory
      DESCRIPTION
         "The MIB Health Status Array is an array of status values representing an
            overall status in element 0 follwed by server and storage status values as follows:

           Octet   Element   Field
          ======== ======= =========
             0        0    Aggregated Status of array elements
             1        1    Status of element 1
             2        2    Status of element 2
             .
             .
             .
             n        n    Status of element n


          Status         0 - Not available
                         1 - Other
                         2 - OK
                         3 - Degraded
                         4 - Failed
             .
             .
    Mibs are assigned an array element as follows.  New items are added at the end.
         0 -  System Health Status (overall status as reported by who is reporting (agents or iLO))
         1 -  Total Aggregate (Includes IML Status)

There is more information in the HP SIM MIB Kit documentation.

Yes, this is correct. I saw that post after asking the question. That explains the meaning of the array (but not really how to use it), despite being buried in the comments of the post. I've been receiving the same management alarms on my G7 servers, which do not have the Agent-less management feature.
