Failed to configure bootvar system for sup-1: imghdr library error in Nexus 7k

[avinash2092]

Hi All,

I am getting below error message when i am trying to configure the boot variable in nexus 7k.

N7k(config)# boot system bootflash:/n7000-s1-kickstart.5.2.9.bin sup-1
Failed to configure bootvar system for sup-1: imghdr library error (0x4045001C)

Need your help on how to resolve this as we have to upgrade the device .

Current version : 5.0.2a

Is it the same if you don't specify the Sup-1 as in Nexus the sup2 will auto upgrade anyway ?active will copy to standby

can you post the current show boot

another option is try issu upgrade

Hi Mark,

I have even tried to set the bootvar without sup-1 but still i am getting the same error.

N7k(config)# boot system bootflash:/n7000-s1-dk9.5.2.9.bin
Failed to configure bootvar system for sup-1: imghdr library error (0x4045001C)
Failed to configure bootvar system for sup-2: imghdr library error (0x4045001C)

We have only single supervisor.

Please find the show boot . Boot variables are showing not set. I have tried for other system and kickstart images. for everything its showing the same error. Am not sure , what would happen if it gets reloaded. 

N7k(config)# sh boot
Current Boot Variables:

sup-1
kickstart variable not set
system variable not set
sup-2
kickstart variable not set
system variable not set
No module boot variable set

Boot Variables on next reload:

sup-1
kickstart variable not set
system variable not set
sup-2
kickstart variable not set
system variable not set
No module boot variable set

Also confirm if using install command would help to complete the upgrade.

Hi

have you uploaded the images to the flash yet can you you post the dir bootflash: output ?

If you use the install its an inline upgrade ISSU , you should not have to reboot the Nexus its cleaner but first you need to have the files in dir as below

Then when there confirmed in flash you set the boot statements and the bootvar will show like this

7kdist-1# show boot
Current Boot Variables:

sup-1
kickstart variable = bootflash:/n7000-s1-kickstart-npe.6.2.12.bin
system variable = bootflash:/n7000-s1-dk9-npe.6.2.12.bin
sup-2
kickstart variable = bootflash:/n7000-s1-kickstart-npe.6.2.12.bin
system variable = bootflash:/n7000-s1-dk9-npe.6.2.12.bin
No module boot variable set

Boot Variables on next reload:

sup-1
kickstart variable = bootflash:/n7000-s1-kickstart-npe.6.2.12.bin
system variable = bootflash:/n7000-s1-dk9-npe.6.2.12.bin
sup-2
kickstart variable = bootflash:/n7000-s1-kickstart-npe.6.2.12.bin
system variable = bootflash:/n7000-s1-dk9-npe.6.2.12.bin

Ok have you tried to use the issu method instead does it return the same results ?

Run in this order with your images

show install all impact kickstart n7000-s1-kickstart.6.0.1.bin system n7000-s1-dk9.6.0.1.bin

install all kickstart n7000-s1-kickstart.6.0.1.bin system n7000-s1-dk9.6.0.1.bin

Hi Mark,

We will try to do that in next maintenance window.

We did a upgrade yesterday in another N7k from 5.1.3 to 6.2.12 and faced some issue.

Whether upgrading directly is recommended also could someone share the prerequisites for the upgrade.

The issue we faced was , the modules got upgraded to 6.2.12 but the physical interfaces were not available for all the modules.

Module and supervisor status was fine.

When we consoled into the switch , we were able to see that the interface configurations were missing.

When we try to configure the interfaces we were getting error messages as below:

N7k# sh run int eth1/1

                         ^
Invalid range at '^' marker.

N7k(config)# int ethernet 1/29

Error: Invalid range: Ethernet1/29.

Kindly suggest why this happened. If we have to enable some features.

Regards,

Avinash
