Nexus 7k: Replacing one of two n7k-sup1's during system operations

[adouthit66]

If I replace one of two n7k-sup1's and the new sup has a different nx-os version. Will the active sup automatically upgrade the new sup or does the new sup need to have the same nx-os version as the active sup?

[Reza Sharifi]

The new Sup needs to have the same NX-OS version as the active Sup.  Only the states and configs are synchronized

Hello Reza,

Thanks for responding. According to the following Cisco documentation you can replace a standby supervisor module and copy the nx-os from the active supervisor module to the standby supervisor module.

Replacing the Standby Supervisor Module in a Dual Supervisor System

You can nondisruptively replace standby supervisor module in a dual supervisor system.

To replace the standby supervisor module, follow these steps:

---

Step 1 Power down the standby supervisor module.

switch# out-of-service module 6

Step 2 Replace the supervisor module. For information on replacing a supervisor module, see the Cisco Nexus 7000 Series Hardware Installation and Reference Guide.

---

Note The replacement supervisor module should boot from the active supervisor module after six minutes. Use the reload module slot-number force command to force the boot.

---

Step 3 Copy the kickstart image from the active supervisor module to the standby supervisor module.

switch# copy bootflash:n7000-s1-kickstart.4.1.2.bin 
bootflash://sup-remote/n7000-s1-kickstart.4.1.2.bin

Step 4 Copy the system image from the active supervisor module to the standby supervisor module.

switch# copy bootflash:n7000-s1-dk9.4.1.2.bin 
bootflash://sup-remote/n7000-s1-dk9.4.1.2.bin

Step 5 Configure the standby supervisor boot variables.

switch# config t

switch# boot kickstart bootflash://sup-remote/n7000-s1-kickstart.4.1.2.bin

switch# boot system bootflash://sup-remote/n7000-s1-dk9.4.1.2.bin 

Step 6 Save these changes to the startup configuration.

switch# copy running-config startup-config

Hi,

That is correct.  You need to manually copy the image from one sup to the other.  The image does not sync authomaticaly from one sup to the other.
