Appendix A - Known Limitations in
Dell PROPack
These are the known limitations in Dell PROPack:
1
How does Dell PROPack handle failure in SCOM/SCE/SCVMM
infrastructure?
The SCE/SCOM-SCVMM infrastructure has multiple software services
(for example, management station, SQL server, and so on) leading to a
complex distributed setup. The exact communication between these
services and the associated failure is handled by the infrastructure itself
and is an internal design care of SCOM/SCE-SCVMM infrastructure.
There are no specific interfaces that SCOM/SCE exposes for the
management pack to make use of. Hence the Dell PROPack design is
independent of these considerations.
2 What happens when multiple alerts are generated for a sensor of the same
severity type?
Dell OpenManage Server Administrator logs events to the Windows
System Event log. Dell PROPack subscribes, as its data source, to the
Windows System Event Log. These events can be Informational,
Warning or Critical in severity type.
Each state transition (except for informational) generates a corresponding
PRO Tip in SCVMM and an alert log in SCOM/SCE.
Assume a Dell PowerEdge system’s temperature sensor probes crosses
warning threshold reading and hence PROPack mechanisms generate the
corresponding PRO Tip for Temperature Warning alert. If another sensor
of the same host crosses warning threshold reading, you cannot see another
PRO Tip for the Temperature Warning alert. Since the PROPack is
primarily concerned with the management of virtualization workloads on
hosts that generated the alerts, there can be only one outstanding
PRO Tip, regardless of the outstanding number of severity events for a
given sensor type on a given host.
