Resetting iDRAC
iDRAC sometimes might not response to the requests coming from the OpenManage Integration for VMware vCenter. The only way to recover from this state is to reset iDRAC. An iDRAC reset performs a normal reboot of the iDRAC. This reboot does not reboot the host. After you perform a reset, it takes 1 or 2 minutes for iDRAC to return to a usable state.
While iDRAC is rebooting, you may see:
Some delay or a communication error while the OpenManage Integration for VMware vCenter obtains its health status.
All open sessions with iDRAC close.
DHCP address for iDRAC may change. If iDRAC uses DHCP for its IP address, then there is a chance that the IP address will change. If this happens, rerun the host inventory job to capture the new iDRAC IP in the inventory data
In vSphere Client, under the Inventory heading, select Hosts and Clusters.
From Hosts and Clusters, select the host system in the tree view and select the OpenManage Integration tab.
Under Host Actions, select iDRAC Reset.
On the iDRAC Rest dialog box, select the Continue iDRAC Reset, and click OK.
