Cisco 4500x SUP Recovery Issues

[Troy C.]

Good Day

First off YES I know this stuff is old, I just manage and have no budget :0) With that said, I currently have multiple SUP cards on 3 different chasis's (SUP 6L+E, 7L+E) all having the same issues. They are up with no redundancy and I do have SUP 8's out there are not redundant so any help with this would be greatly appreciate for future failures.

When looking at the bootflash of each failed SUP, they've lost their IOS image completely. So, I've attempted many times to use the CF Card/Slot0: and TFTP to do a full recovery. It will begin the process of loading the SUP but then says there is no image in bootflash, (obviously or I'd load it).

I've read many forums etc. and have had no issues with TFTP communications etc. only that it doesn't do what it says it did for others. It currently does not go into a boot loop on its own, but if I load from TFTP or CF card it will loop 4-5 times then get stuck in rommon.I've disabled Autoboot a few times but it still goes to rommon looking for the file bootflash, I tried using the set command and playing with the config-register, the only options are 0x2100, 0x2101 and 0x2102 with the same result. I might also add, it completes is POST successfully every time.

When I unset boot and begin the recovery process and and tells me that the following is missing:

BOOT=bootflash:cat4500e-entservicesk9-mz.152-2.E8.bin,1;

No matter what the confreg says, or different outputs from my various attempts, it reverts to 0x2102 displays that the image is missing from bootflash.

config-register = 0x2102
Autobooting using BOOT variable specified file.....

Current BOOT file is --- bootflash:cat4500e-entservicesk9-mz.152-2.E8.bin
boot: can not load "bootflash:cat4500e-entservicesk9-mz.152-2.E8.bin"

I know.... and that's the issue, I just need to get it to load from TFTP to get it online and then copy the new image over to bootflash:. Not being able to edit the bootvar etc. without IOS is extremely annoying.

Has anyone else had this issue? Any advice would be great.

Thanks.

What chassis this SUP card installing and testing ?

Can you post complete boot logs which is failing.

Note : as you mentioned you went many documents i do not want to recommend at this stage what document refer (i would like to see complete boot logs and errors you getting from the time of switch on to booting with image)

[Troy C.]

Chassis Type : WS-4507 R+E

Sup 6L-E 10GE (X2), 1000BaseX (SFP) WSX-X45-SU6L-E

As mentioned I've tried several options like confreg 0,1,2 etc but the output is the same so I'll post a couple.

I can go back tomorrow, we just had a power outage so this was in my TeraTerm from before.

There's not a lot of helpful info in there. It was getting stuck using TFTP at diagsk5 version 5.0.2.3 a few times as well.

Yeah, nah.  It is not 0x2101 but still at 0x2101.

Nope.  This one still says 0x2102.

[Troy C.]

Hi Leo and thanks for the reply.

I've done that many times. It begins to load, refers to bootflash: where there is no IOS and reloads. It also says boot and bootldr can only be changed in IOS. I'm not sure why but it always comes back to the same thing, the original 0x2102 and looks for the file in bootflash. 

Here is the output from it, it just repeats the process until I Control C:

This is the wrong syntax.  The "BOOT" keyword is very case sensitive.

How is the config-registry changed?  The command, in ROMMON, is different.  It should be "confreg 0x02101".

As you can see bolded below, it will not take capital letters, only small.
