Boot Image Issue after ios upgrade

Hello Damien,

I think that the switch tries to boot on what has been defined in the boot statment(s) => boot system commands..

As the switch does not find the file (defined by the boot statments) it tries to boot on the next found image (here the old => c2960-lanbase-mz.122-35.SE5/ c2960-lanbase-mz.122-35.SE5.bin)..

In fact, in the boot.jpg we need to see the complete boot bath.

If you issue a ‘show running | include boot I suppose you will see

=> boot system c2960-lanbasek9-mz.150-1.SE.bin

If yes you can normalize the boot statments by entering the following commands =>

no boot system c2960-lanbasek9-mz.150-1.SE.bin   

boot system flash:c2960-lanbasek9-mz.150-1.SE.bin

write mem

show boot should then show the complete path. Then reload and check.

============================================================================

Also we can see in the flash that the old IOS is a .tar image (in the form of a directory in the flash => c2960-lanbase-mz.122-35.SE5/c2960-lanbase-mz.122-35.SE5.bin).

It contains the .bin file and other html files...(cd c2960 ..... to see what is inside).

  • The .bin file is the Cisco IOS Software image. If you want to use only the CLI to manage the switch, this is the only file you need to download.
  • The .tar file is an archive file from which both the IOS image and the files are extracted during the upgrade process. It is necessary if you want to manage your switch (or switch Stack –but not applicable in your case) through a web interface (HTML).

FYI, you may certainly know it but the upgrade procedure for the .tar image is different => http://www.cisco.com/en/US/docs/switches/lan/catalyst3750/software/release/15.0_1_se/release/notes/OL25301.html#wp1042738 (applicable for 2960).

Hope that helps

Kind regards.

Hi,

Please use the comand " boot flash" to specify the default boot image in global configuration mode. This should help.

Please stay away from IOS version 15.0(1)SE.  I'm still testing 15.0(1)SE1.
