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 ashed 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 rmimg.d7 to the SD card.

• Insert the SD card into the server.

• Bootloader detects the SD card, turns the ashing LED to solid amber, reads the rmimg.d7, reprograms iDRAC, and then

reboots iDRAC.

Using TFTP server

You can use Trivial File Transfer Protocol (TFTP) server to upgrade or downgrade iDRAC rmware or install certicates. It is used in

SM-CLP and RACADM command-line interfaces to transfer les 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 certicates and update rmware, 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 prole

You can back up the system conguration, including the installed rmware images on various components such as BIOS, RAID, NIC,

iDRAC, Lifecycle Controller, and Network Daughter Cards (NDCs) and the conguration settings of those components. The backup

operation also includes the hard disk conguration data, motherboard, and replaced parts. The backup creates a single le 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 rmware and server conguration 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

• To perform backup on a vFlash SD card:
