Enabling Last Crash Screen
To troubleshoot the cause of managed system crash, you can capture the system crash image using iDRAC7.
To enable the last crash screen:
1. From the
Dell Systems Management Tools and Documentation DVD, install Server Administrator on the managed
system.
For more information, see the Dell OpenManage Server Administrator Installation Guide at dell.com/support/
manuals.
2. In the Windows startup and recovery window, make sure that the automatic reboot option is not selected.
For more information, see Windows documentation.
3. Use Server Administrator to enable the Auto Recovery timer, set the Auto Recovery action to Reset, Power Off, or
Power Cycle
, and set the timer in seconds (a value between 60 - 480).
For more information, see the Dell OpenManage Server Administrator Installation Guide at dell.com/support/
manuals.
4. Enable the Auto Shutdown and Recovery (ASR) option using one of the following:
– Server Administrator — See
Dell OpenManage Server Administrator User’s Guide at dell.com/support/
manuals.
– Local RACADM — Use the command:
racadm config -g cfgRacTuning -o cfgRacTuneAsrEnable 1
5. Enable Automated System Recovery Agent. To do this, go to Overview → iDRAC Settings → Network → Services,
select Enabled and click Apply.
Enabling or Disabling OS to iDRAC Pass-through
In servers that have Network Daughter Card (NDC) or embedded LAN On Motherboard (LOM) devices, you can enable
the OS to iDRAC Pass-through feature that provides a high-speed bi-directional in-band communication between
iDRAC7 and the host operating system through a shared LOM (rack or tower servers) or a dedicated NIC (rack, tower, or
blade servers). This feature is available for iDRAC7 Enterprise license.
When enabled through dedicated NIC, you can launch the browser in the host operating system and then access the
iDRAC Web interface. The dedicated NIC for the blade servers is through the Chassis Management Controller.
Switching between dedicated NIC or shared LOM does not require a reboot or reset of the host operating system or
iDRAC.
You can enable this channel using:
• iDRAC Web interface
• RACADM or WS-MAN (post operating system environment)
• iDRAC Settings utility (pre-operating system environment)
If the network configuration is changed through iDRAC Web interface, you must wait for at least 10 seconds before
enabling OS to iDRAC Pass-through.
If you are using the XML configuration file through RACADM or WS-MAN and if the network settings are changed in this
file, then you must wait for 15 seconds to either enable OS to iDRAC Pass-through feature or set the OS Host IP address.
Before enabling OS to iDRAC Pass-through, make sure that:
• Host operating system and iDRAC7 are in the same subnet.
• Host operating system IP address is configured.
