Upgrade Nexus 7000 9 slot with FEX

We are Planning to have an upgrade on the Nexus 7000 to the version 7.3.3.D1.1.

In our infrastructure, we have FEX , some of them are dual home and other are single Homed..

As described in the link below the ISSU is not supported when we have Dual Homed Host (Active/Active) and Active-Active FEX  Design

https://www.cisco.com/c/en/us/support/docs/switches/nexus-2000-series-fabric-extenders/200363-nexus-2000-fabric-extenders-supported-un.html#anc18

so if we have to go with the disruptive upgrade, the servers connected to the FEX will lose  connectivity for about 15 min ( time estimated for the FEX to be upgraded) . 

The problem is we can't afford 15 min downtime...  Any suggestion ?

Re: Upgrade Nexus 7000 9 slot with FEX

is your server configured as Active / Active LACP?

 

other way you can do is make Server as Active-Standby port config. reboot the FEX with control.
