Failure of firmware update on 11

generation of

servers

Firmware updates applied on 11

generation of PowerEdge servers may fail due to incompatible versions of iDRAC and LC with the

following error: WSMan command failed to execute on server with iDRAC IP <IP address>.

As a workaround, upgrade the iDRAC and LC to the latest versions, and then apply the firmware updates. The table lists out the latest

versions of LC and iDRAC.

Changing of polling and notification bell color after

updating the frequency

If a managed server is not discovered in OMIMSSC, and you change the frequency of polling and notification option, the bell color changes

to yellow after sometime, even if there are no changes in the catalog.

As a workaround, discover managed servers and then change the frequency of polling and notification option.
