ASA 5506-X with Firepower Services shows warming There are differences between boot sector and its backup.

Hi,

 

after update the ASA image, I've noticed the following messages/warnings after reboot:

(I use the following ASA image: asa984-15-lfbff-k8.SPA)

Configuring network interfaces... done.

Populating dev cache

dosfsck 2.11, 12 Mar 2005, FAT32, LFN

There are differences between boot sector and its backup.

Differences: (offset:original/backup)

  65:01/00

  Not automatically fixing this.

Starting check/repair pass.

Starting verification pass.

WARNING: Attribute already exists in the dictionary.

 

sh module shows: (see below attached picture)

 

I do not really found a solution to to fix it. Some recommend to do a ROMMON update?

Does anyone has an idea, how to fix the it?

It seems up to now, that the ASA works as before, but especially the boot sector thing makes me 

a little bit nervous.

Many thx in advance

Peter

Re: ASA 5506-X with Firepower Services shows warming There are differences between boot sector and its backup.

The unit is just giving you a warning. nothing else. With 5506-X you can only go upto ASA code asa 992-47-lfbff-k8.SPA with firepower module 6.2.x.

 

you only upgrade the image? show us the output command show run boot and show bootvar

Hi,

 

here it is .....

 

ciscoasa# show run boot
boot system disk0:/asa984-15-lfbff-k8.SPA
boot system disk0:/asa9-10-1-30-lfbff-k8.spa

 

ciscoasa# show bootvar

BOOT variable = disk0:/asa984-15-lfbff-k8.SPA;disk0:/asa9-10-1-30-lfbff-k8.spa
Current BOOT variable = disk0:/asa984-15-lfbff-k8.SPA;disk0:/asa9-10-1-30-lfbff-k8.spa
CONFIG_FILE variable =
Current CONFIG_FILE variable =

Re: ASA 5506-X with Firepower Services shows warming There are differences between boot sector and its backup.

you need some tidy up on this unit.

if you want to keep the image 9.8.x in that case you have to give these command.

!

boot system flash:asa984-15-lfbff-k8.SPA

no boot system flash:asa9-10-1-30-lfbff-k8.spa

 

this above command will fix the issue mean when you box reboot next time it will pick the 9.84 image. instead of 9.10.

 

 

here

BOOT variable = disk0:/asa984-15-lfbff-k8.SPA;disk0:/asa9-10-1-30-lfbff-k8.spa
Current BOOT variable = disk0:/asa984-15-lfbff-k8.SPA;disk0:/asa9-10-1-30-lfbff-k8.spa

 

you let it decide to either pick up 9.84 and 9.10.

 

 

 

i guess because of this you were getting the error.

Re: ASA 5506-X with Firepower Services shows warming There are differences between boot sector and its backup.

Hi,

 

I did:

 

ciscoasa# conf t

ciscoasa(config)# no boot system disk0:/asa984-15-lfbff-k8.SPA

ciscoasa(config)# no boot system disk0:/asa9-10-1-30-lfbff-k8.spa

ciscoasa(config)# boot system flash:/asa984-15-lfbff-k8.SPA

 

I got the following info (never saw this?)

INFO: Converting flash:/asa984-15-lfbff-k8.SPA to disk0:/asa984-15-lfbff-k8.SPA

ciscoasa(config)# .   ?????????

in my config I see again:

boot system disk0:/asa984-15-lfbff-k8.SPA .    (see above)

some warnings ....

Starting udev
Configuring network interfaces... done.

Re: ASA 5506-X with Firepower Services shows warming There are differences between boot sector and its backup.

Hi,

I found this too, but there is only asa992-lfbff-k8.SPA on SW download webpage available. I don't see version 9.9(2.39) oder .46?  Expanded all. You said above a higher version would not work with firepower 6.2 ?

 

Thx

Do you have a TAC support? if so you can do RMA this unit.
