Recovering iDRAC
iDRAC supports two operating system images to make sure a bootable iDRAC. In the event of an unforeseen catastrophic error and
you lose both boot paths:
•
iDRAC bootloader detects that there is no bootable image.
•
System Health and Identify LED is flashed at ~1/2 second rate. (LED is located on the back of a rack and tower servers and on
the front of a blade server.)
•
Bootloader is now polling the SD card slot.
•
Format an SD card with FAT using a Windows operating system, or EXT3 using a Linux operating system.
•
Copy
firmimg.d7
to the SD card.
•
Insert the SD card into the server.
•
Bootloader detects the SD card, turns the flashing LED to solid amber, reads the firmimg.d7, reprograms iDRAC, and then
reboots iDRAC.
Using TFTP server
You can use Trivial File Transfer Protocol (TFTP) server to upgrade or downgrade iDRAC firmware or install certificates. It is used in
SM-CLP and RACADM command-line interfaces to transfer files to and from iDRAC. The TFTP server must be accessible using an
iDRAC IP address or DNS name.
NOTE: If you use iDRAC web interface to transfer certificates and update firmware, TFTP server is not required.
You can use the
netstat -a
command on Windows or Linux operating systems to see if a TFTP server is running. The default
port for TFTP is 69. If TFTP server is not running, do one of the following:
•
Find another computer on the network running a TFTP service.
•
Install a TFTP server on the operating system.
Backing up server profile
You can back up the system configuration, including the installed firmware images on various components such as BIOS, RAID, NIC,
iDRAC, Lifecycle Controller, and Network Daughter Cards (NDCs) and the configuration settings of those components. The backup
operation also includes the hard disk configuration data, motherboard, and replaced parts. The backup creates a single file that you
can save to a vFlash SD card or network share (CIFS or NFS).
You can also enable and schedule periodic backups of the firmware and server configuration based on a certain day, week, or
month.
Backup feature is licensed and is available with the iDRAC Enterprise license.
NOTE: In 13th generation servers, this feature is automatically enabled.
Before performing a backup operation, make sure that:
•
Collect System Inventory On Reboot (CSIOR) option is enabled. If you initiate a back operation while CSIOR is disabled, the
following message is displayed:
System Inventory with iDRAC may be stale,start CSIOR for updated inventory
