Remote iDRAC hard reset
Using iDRAC, you can monitor the supported servers for critical system hardware, firmware, or software issues. Sometimes, iDRAC may
become unresponsive due to various reasons. During such scenarios, you may have to turn off the server by plugging it off from the
socket, after which the iDRAC can be reset.
Using the Remote iDRAC hard reset feature, whenever iDRAC becomes unresponsive, you can perform a remote iDRAC reset operation
without the need to shut down the server. To reset the iDRAC remotely, ensure that you have administrative privileges on the host OS. By
default, the remote iDRAC hard reset feature is enabled.
iDRAC access via Host OS (Experimental Feature)
Using Dell’s PowerEdge Servers, you can manage the hardware or the firmware of a device through iDRAC by configuring an iDRAC
dedicated network. Through the dedicated network port, you can access the iDRAC interfaces such as GUI, WSMAN, RACADM, and
Redfish client.
The prerequisite to manage the hardware or the firmware is to have a dedicated connection between a device and the supported iDRAC
interface. Using the iDRAC access via Host OS feature, you can connect to an iDRAC interface from an OS IP or host irrespective of the
connection between a device and an iDRAC dedicated network. This feature allows you to monitor the hardware or firmware even if the
iDRAC is not connected to the servers.
NOTE: After you configure this feature, append the URL with login.html to access iDRAC from the operating system.
For example, https:// <IP address>:<listen port number>/login.html.
In-band support for iDRAC SNMP alerts
Using iDRAC, an out-of-band server management and monitoring tool, the SNMP traps/alerts can be recorded in the log. However, from
a host OS systems management using in-band agent perspective, the preference is more on the SNMP alert received from the host OS
than the traps received from iDRAC. When an SNMP alert is received from iDRAC, it would be challenging to determine the source of the
alert as it is from an iDRAC IP and not the system IP.
Using iDRAC Service Module 2.4, you can receive SNMP alerts from the host OS which is similar to the alerts that are generated by
iDRAC.
NOTE:
By default this feature is disabled. Though the In-band SNMP alerting mechanism can coexist along with iDRAC
SNMP alerting mechanism, the recorded logs may have redundant SNMP alerts from both the sources. It is
recommended to either use the in-band or out-of-band option, instead of using both.
NOTE: You can use the In-band SNMP feature on 12th generation of Dell’s PowerEdge Servers or later with a minimum
iDRAC firmware version 2.30.30.30.
NOTE: If you choose to enable the In-band SNMP alerts feature during custom installation of iDRAC Service Module, by
default the Lifecycle Log Replication feature is enabled.
