Dell Server Workstation iDRAC Dead after Firmware Update Solution R720, R320, R730

This is certainly a poor design, as you can read many seasoned admins who have updated their iDRAC only to have it killed.  One possible cause is not by doing all the incremental updates, doing updates from an old iDRAC to one many revisions newer is a sure way to kill things, but even then there is no guarantee based on the amount of failures.

 

List of threads of people's dead iDRAC's:

The first solution is don't mass update, as we've seen entire datacenters or racks full of Dell machines with dead iDRAC due to mass update attempts.  It is likely not practical to do this fix on a wide scale unless you can migrate the applications to another facility or rack as this requires the servers to be pulled off the rack or at least pulled by the rails and to open the case of course.

Try This First (only if you have lights on the iDRAC):

https://www.dell.com/support/kbdoc/en-us/000120131/poweredge-idrac-recovery-procedure-with-firmimg-d7

This solution is for if your iDRAC is totally dead, no flashing lights, dead NIC etc...

You will first need a USB to TTL adapter like this Amazon affil link.

Story of successful recovery.

Another successful recovery: http://blog.ignoranthack.me/?p=86

More discussion of the issue.

You will see Dell themselves advising to replace the motherboard, but in many cases by connecting to the UART below with a USB to TTL cable, you can tell the iDRAC to reflash from the SDCARD image.

 

Based off this example of a Dell R720, we can see the UART pins which are labelled by this github user.

This area is at the back right of the server (if looking from the server from the front) and will require you to remove the riser cage to access this area.

Step 1.) Connect to USB to TTL adapter.

Be sure to use the correct pins below (remember the TX side of the TTL goes to the RX side of the UART and the the RX side of the TTL goes to the TX side of the UART).  If in doubt, use a multimeter to make sure you aren't connecting to the wrong pins/getting voltage where you shouldn't be.

 

 

 

Note About Format of SD Card

I have seen this occur on some servers, I am not sure how it was done like this but the SD Card came formatted as the root drive, without any partition.  It seems that U-Boot recovery DOES NOT like this, or the fact that it is a 16GB Card even though it is from Dell.


UTIL RECOVER:Transport:sd  TargetMMC:EMMC  File:firmimg.d7
UTIL RECOVER:ERROR:Could not locate 'firmimg.d7' in FAT or EXT2 file system.

If you get the errors above and you are sure the file exists, then it is worth doing the following.

1.) Backup all files from the SD Card.

2.) Completely wipe the card.

3.) Format a single partition as 2GB as ext2 (ext2 not ext3 or ext4 or it won't work as the environment does not have the kernel modules to load anything but FAT and EXT2).

 

Step 2.) Recover

Sometimes you may need to go through 2 rounds of bootup procedure by hitting all the annoying keys to get the server booted normally for this to work.

Connect using minicom or screen and run these commands:

screen /dev/ttyUSB0 115200

The connection speed is crucial, otherwise you will see nothing or garbage characters.

If all goes well you should see like below.

Make sure you have the file firmimg.d7 or whatever the name one is from the iDRAC firmware on the SD card that inserts at the front of the server.

util recover -emmc -from sd -f firmimg.d7 -noreset -clear

Some versions will not have this -from_sd option

iDRAC8=> util recover -emmc -from_sd -f firmimg.d6 -noreset -clear
util recover:mcgetopt:ERROR: option "-from_sd" was not found.


Then once the above completes do this:

util reset

 

Short iDRAC DBG interrupt/reboot pins

If you see a shell prompt like below (SH7757), you will need to short the DBG pins in the image from earlier.

Use a paper clip to short the two pins shown above as the interrupt/reboot pins in the diagram above.

After shorting you should see U-Boot again:

Full Recovery Output

Sometimes it does not go well especially if you didn't know your EMMC is bad where it stores the firmware.

Not having the -noreset and -clear seems to have created this situation, with the waitpid but at that point the iDRAC lights and NIC were flashing.  I then hard powered down and had to use the DBG pins to get back into U-Boot.
