Unable to reload

[windell.alvarez]

Im upgrading an ios and ran into some issue. I don't know what this mean. I tried to search it but cant find the answer.

Can someone enlightened me.

cor01-6506#reload

Reload to the ROM monitor disallowed from a telnet line.

Set the SP configuration register boot bits to be non-zero.

Thanks in advance

Windell,

What is your configuration register set to? There is a setting to prevent the switch from being reloaded via a VTY line.

Mark,

Configuration register is 0x2102

Make sure the SP conf. reg. is the same as the RP conf reg.

From the exec privilege prompt, do a "remote command switch sho bootvar" and make sure it is also set to 0x2102.

Thanks Victor!

It was set to 0x0, but how can i change it?

cor01-6506#remote command switch show bootvar

BOOT variable = bootflash:s72033-jk9sv-mz.122-17d.SXB6.bin,

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x0

[windell.alvarez]

I got it!

both the RP and the SP are now set to 0x2102.

thanks again!

Windell:

Great!

Please rate all posts.

Ok Windell, but how did you got it?

I'm having the same exactly issue than you :(

It's a bit counter-intuitive to fix this.  You have again set the config register on the RP, which will then get propograted to the SP.

Router#reload
Reload to the ROM monitor disallowed from a telnet line.
Set the SP configuration register boot bits to be non-zero.

Router#remote command switch show bootvar

BOOT variable = s72033-adventerprisek9-mz.151-2.SY5.bin,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x0

Router#conf t
Router(config)#config-register 0x2102
Router(config)#exit

Router#remote command switch show bootvar

BOOT variable = s72033-adventerprisek9-mz.151-2.SY5.bin,1;
CONFIG_FILE variable does not exist
BOOTLDR variable does not exist
Configuration register is 0x0 (will be 0x2102 at next reload)

Router#reload

System configuration has been modified. Save? [yes/no]: yes
Building configuration...
[OK]
Proceed with reload? [confirm]

I just upgraded 2 4500 chassis and had the problem on the 2nd one.

Suprisingly, there's only 1 sup and the customer says it hasn't changed for years, and was rebooted since.

Anyways, the solution is to re-apply : config-register 0x2102

and reboot
