Polling of Discovered Dell Devices

In Network Manager, polling of the discovered Dell devices is a mechanism to monitor their global health status, using

specific polling policies and polling definitions.

The health status of the polled device is displayed in the Network View and Hop View in the following format:

• Critical — Event that indicates loss of data or function such as a hardware failure.

• Normal — Event with successful operation of a component such as a power supply turning on.

• Warning — Event that may indicate a possible future problem such as crossing a warning threshold.

NOTE: The Store Poll Data option is not available.

If the health of a device turns from one status to the other, the latest status overwrites the previous status of the device.

For polling DCLM, make sure that the Dell OOB servers are discovered on the systems and the DCLM parameters are

configured. Based on the number of available licenses, the possible status of DCLM is:

• DCLM critical — License is not available.

• DCLM warning — License has reached the limit, but system is running with a grace license.

• DCLM normal — License is available.

On Dell PowerEdge 9th to 12th generation servers, the polling is done through the in-band process, but on Dell

PowerEdge 12th generation servers, the polling is done through the in-band and out-of-band (OOB) mechanisms. You

can enable or disable only the in-band polling on Dell PowerEdge 9th to 12th generation servers, or the OOB polling on

Dell PowerEdge 12th generation servers, or both.

For polling Dell servers running ESXi, if the server is not reachable or WS-MAN communication fails, then a minor alert

is generated. This alert is cleared by the next polling alert if the device is reachable and the WS-MAN communication is

established.

For polling Dell EqualLogic storage arrays, if the EqualLogic device is not reachable or SNMP communication fails

during the polling, then a minor alert is generated. This alert is cleared by the next polling alert if the device is reachable

and SNMP communication is established.

For polling Dell PowerVault MD Storage Arrays, if the MD Array device is not reachable during the polling, a minor alert

is generated. This alert is cleared by the next polling alert if the device is reachable.

CMC and OOB Devices

To begin polling of Dell devices, configure the polling policies and definitions for each device. Following are the list of

policies:

• DellServerPoll — This poll policy is used for polling Dell monolithic servers, modular servers and servers

running Windows and Linux and contains the following poll definitions:

– DellServerCriticalDef — Used for polling Dell servers for critical conditions.

– DellServerWarningDef — Used for polling Dell servers for warning conditions.
