Problem

Sometimes the Cisco Switch Stack or one member of Switch stack failed to upgrade to a new IOS version or firmware. In this article, we will discuss how to resolve the issue if the switch is failing to upgrade to a new IOS or firmware. Here we have a switch stack having 4 members and one member of the switch stack is failing to upgrade to the new firmware. Here we are upgrading firmware from version 150-2a.EX5 to version 152-7.E3 and one switch is failing to boot with new firmware.

Solution

In this case, the fourth switch of the Cisco Switch Stack is failing to upgrade to the new Firmware or IOS. Sometimes 2 or 3 switches of Cisco Switch Stack failed to upgrade to the new Firmware or IOS. The solution is same for all the members of the switch stack which is failing. Follow the step to resolve the issue of upgrade failure

Step1: Stack Removal
Remove the switch(s) from the stack which is (are) failing to upgrade to the new firmware.

Step2: Console
Take console access of the switch which is failing to upgrade. If more than one switch is failing to upgrade then perform the steps on each switch one by one.

Step3: Check Flash
Access the flash file of the switch and ensure the new firmware file exists in the flash. See the output as shown below for the 4th switch of the Cisco Switch Stack.

Step4: Check Boot System
Check the image which is set in the current boot system.

edledge-switch#sh boot
BOOT path-list : c2960x-universalk9-mz.152-7.E3.bin
Config file : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break : yes
Manual Boot : no
HELPER path-list :
Auto upgrade : yes
Auto upgrade path :
NVRAM/Config file
buffer size: 524288
Timeout for Config
Download: 0 seconds
Config Download
via DHCP: disabled (next boot: disabled)

Step5: Change System Boot
Change the system boot and set it to “no boot system” as shown below

edledge-switch#conf t
edledge-switch(config)#
edledge-switch(config)#no boot system
edledge-switch(config)#
edledge-switch(config)#exit
edledge-switch#

Step6: Set New Image
Set the boot system with the new image using the flash as shown below.

edledge-switch#conf t
edledge-switch(config)#boot system flash:/c2960x-universalk9-mz.152-7.E3.bin
edledge-switch(config)#exit
edledge-switch#

Step7: Boot Confirmation
Check system boot to ensure the new file is set up as a boot file as shown below.

edledge-switch#sh boot
BOOT path-list : flash:/c2960x-universalk9-mz.152-7.E3.bin
Config file : flash:/config.text
Private Config file : flash:/private-config.text
Enable Break : yes
Manual Boot : no
HELPER path-list :
Auto upgrade : yes
Auto upgrade path :
NVRAM/Config file
buffer size: 524288
Timeout for Config
Download: 0 seconds
Config Download
via DHCP: disabled (next boot: disabled)

Step8: Save & Reload
Save the config. and then reload the switch.

edledge-switch#wr
Building configuration...
[OK]

edledge-switch#reload
Proceed with reload? [confirm] [Enter]

Step9: Check Version
Check the Firmware Version after the switch reloads to ensure the switch has booted up on new firmware.

edledge-switch#sh version

Step10: Connect Stack
Connect the switch back to the stack which was disconnected earlier.

Step11: Confirm the Version
Check the version of the switch after connecting to the stack.

edledge-switch#sh version
