Can someone help me with upgrading this switch?

Note :

I have 2 cisco 5548up switches in a fabric. I am facing this issue only one switch. Another switch not throwing this error.

Currently, both the switches are the same firmware version(7.1(4)N1(1)).

Hi @binodsatapathy7 

You have two problems mentioned there:

Service "stp" in vdc 1: Port: Ethernet1/15 in VLAN0053 is Designated. Topology change could occur during ISSU.
Upgrade needs to be disruptive!!!

For ISSU to Proceed, Check the Following Criteria :
1. No Topology change must be active in any STP instance
2. Bridge assurance(BA) should not be active on any port (except MCT)
3. There should not be any Non Edge Designated Forwarding port (except MCT)
4. ISSU criteria must be met on the VPC Peer Switch as well

If Ethernet1/15 is connected to a server/endpoint/device not running STP, configure it as an edge port:

conf t
interface eth x/y
spanning-tree port type edge

If your N5K is not a leaf in your STP topology and you cannot configure the port as edge, then your upgrade will be disruptive (non-ISSU).

FAIL. Return code 0x4093007C (Issu cannot be done, bootflash is busy).

Bootflash is busy due to :
[1] Open or active SFTP session. Close the sftp session and try the "install all" command again.

Do you have any SFTP connection opened? If yes, close it and try again the install all cmd.

If you want to force a cold upgrade (non-ISSU), you can do it through:

install all force kickstart <kickstart_image.bin> system <system_image.bin>

Cheers,

Sergiu
