Aruba/HPE 5400zl2 In Service Software Upgrade

Has anyone figured out how to do a live switch with dual controllers fail-over in-service software upgrade without rebooting the switch? Is it even possible? 

 

Thanks for any information!

Re: Aruba/HPE 5400zl2 In Service Software Upgrade

Speaking about a standalone Aruba 5400R zl2 chassis, two Management Module (MM) related redundancy mechanisms (Standby and NonStop switching) are available: redundancy of MM is available when you have a chassis working in standalone mode (non VSF) and when it is equipped with two MMs.

 

NonStop switching MMs redundancy mode provides the least disrupting software update experience (almost hitless).

 

ISSU mechanism instead is typically a feature found when you're dealing with IRF capable switches so exactly when you're dealing with two or more switch clustered together in a virtual switch (as example, it is generally available on almost all non low-end HPE FlexNetwork switches running Comware NOS).

 

Alternatively Aruba 5400R zl2 is driven by ArubaOS-Switch and it provides VSF (similar to a two members IRF with particular restrictions and requirments): VSF has a Fast Software Upgrade (FSU) option which is "mimicking" an ISSU procedure...but here we're indeed speaking of two chassis virtualized at first (as happens with IRF) and not about a single standalone chassis.
