6509 Supervisor 32 redundancy issue

Anthony Walters
Level 1
Level 1

Hello,

i have 2 sup32's that i just upgraded the IOS on. they were both stable, 1 being active and the other being hot. I then write erase(d) the ios on the sup1 and rebooted. now the sup1 is up but sup2 is in an unknown state. i consoled into the sup2 (unknown) and it is in rommon mode. i am familiar with rommon and uploading IOS. My question is, can i load the IOS from the active supervisor module? I believe the boot variable is incorrect.

Any help is appreciated.

Regards!

No.

I believe the boot variable is incorrect.

Then console into the sup 2 and type "boot :IOS.bin".

Hello Anthony,

You cannot access redundant switch file systems while in ROMMON but you can boot it first (using "boot " command, such as "boot bootdisk:image.bin") and then copy correct image while in IOS. E.g. to copy from active to standby route processor flash the command is :

  copy bootflash: slavebootflash:

To see the list of available file systems you can use command "show file systems".

Kind Regards,
Ivan

This worked.

Thank you!

Another question,

Why is my standby sup32 having issues. It is going to rommon. I console into the rommon and tell it to boot from disk0 and it comes up ok.

I believe I am missing the boot statement in the config? Here is an output of my chassis

Hi Anthony,

Possible config-register is incorrect on switch or route processors. Or boot string is incorrect.

Please check for that by booting the supervisor and executing the following commands:

  remote command standby-sp show boot

  remote command standby-rp show boot

I suppose you are running SSO redundancy, otherwise this commands may not work.

If you see config-register different from 0x2102, execute the following commands to change it:

conf t

   conf-reg 0x2102

   end

wr

After that you should see correct values:

  remote command standby-sp show boot

  remote command standby-rp show boot

Also check if the boot string image exists on the standby sup in the same location as on active.

Kind Regards,
Ivan

Router#remote command standby-sp show boot

Standby not ready yet. Try later.

Router#remote command standby-rp show

Router#remote command standby-rp show

Standby not ready yet. Try later.

Hi Anthony,

"Standby not ready yet"  means that standby is either not booted (e.g. in ROMMON) or in not synronized with active yet. Did you confirm the standby is up and running? You can do it by checking module status in "show module" or redundancy status in "show redundancy".

Ivan

Done. Thank you.

Booted the rommon

Went back to active sup, formatted hot flash, recopied ios, verified ios, then set boot:

BOOT variable = sup-bootdisk:s3223-advipservicesk9_wan-mz.122-33.SXI5.bin,1;

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x2102

Standby is up

Standby has 524288K/65536K bytes of memory.

Standby BOOT variable = sup-bootdisk:s3223-advipservicesk9_wan-mz.122-33.SXI5.bin,1;

Standby CONFIG_FILE variable does not exist

Standby BOOTLDR variable =

Standby Configuration register is 0x2102

Hi Anthony,

This settings look good. Did you check if the standby auto-boots after reload now? You can verify it by manually reloading standby with "hw-mod slot reset".

Ivan

Hi Guys,

I have upgraded to IOS version s3223-adventerprisek9_wan-mz.122-33.SXJ4.bin and since I upgraded the SSO is not working.

The redundand Sup loads the IOS and when it tries complete the process it reboots the whole time. This is happening on 4 out of 60 switches I upgraded. All is using sup32 and same IOS version.

I have lookup up on this and didn't find anything rock solid for this.

Can you guys help please?

Regards,

Clifton.
