cpstop/cpstart on cluster R77.30 with VSX

Hi,

I have a cluster with two 21400 with R77.30 and VSX.

In order to fix a problem I have to make a cpstop, do something not relevant and then cpstart, I am worried about how the cpstop impact on cluster and VSX and I am looking for a procedure. 

1) On standby unit give cpstop - How it impact on VSX interface ? It is possible a split brain or active/active ? Other considerations?   Some more details about what's happen ?

2) On standby unit give cpstart

3) failover the cluster

4) repeat on new standby unit

 

Checkpoint support said there is impact, but I have to understand in details what kind of impact and why.

Any help?

thanks

Re: cpstop/cpstart on cluster R77.30 with VSX

If you are using VSX in HA mode, there is an impact of failover (1-2 seconds or less of lagged traffic) on step 3. No impact when performing cpstop on standby.

If you are using VSLS, there will be some traffic lags on step 1 and 3
