Remote iDRAC hard reset

iDRAC may become unresponsive due to various reasons. iSM can fully reset an unresponsive iDRAC8 or iDRAC9 controller by temporarily

removing power to the iDRAC controller without aecting operating system production. To reset iDRAC, use the following Windows

PowerShell or Linux shell command:

./Invoke-iDRACHardReset

NOTE: This feature only works with iDRAC8 on the 13

generation PowerEdge servers or later and if logged into the operating

system as an administrator.

iDRAC access via Host OS

Using Dell’s PowerEdge Servers, you can manage the hardware or the rmware of a device through iDRAC by conguring an iDRAC

dedicated network. Through the dedicated network port, you can access the iDRAC interfaces such as GUI, WSMAN, RACADM, and

Redsh client.

The prerequisite to manage the hardware or the rmware 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 rmware even if the

iDRAC is not connected to the servers.

You can select any of the following sub features to enable the iDRAC access via Host OS:

• Access via GUI, WS-man, Redsh, Remote Racadm

• In-band SNMP Traps

• Access via SNMP Get

If you select iDRAC access via Host OS, all the sub features are selected by default. If you want to select any one of the individual sub

feature, you can select a particular feature and enable it.

For more information, see iDRAC Access via Host OS whitepaper.

Accessing iDRAC Via GUI, WS-man, Redsh, Remote

RACADM

Access via GUI, WS-man, Redsh, Remote Racadm feature enables a Host OS administrator to access iDRAC interfaces remotely via the

Host OS. Type the URL https:// <Host OS IP Address>: <ListenPortNumber> in the browser of the remote management

station to access the iDRAC GUI.

NOTE

: The ListenPortNumber is the port number congured while enabling the iDRACAccessviaHostOS feature in iSM.

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.

Starting from 14

generation of servers, all events that have the SNMP Trap option as the target (in the Alerts page or in the equivalent

RACADM or WSMAN interfaces) can be received as SNMP trap through the OS using the iDRAC Service Module. For iDRAC rmware

3.0.0 or later, this feature does not require iSM LCL replication feature to be enabled. Only the events logged in the LC log after the iDRAC

Service Module was installed are sent as SNMP traps.
