Splitting 2 production Viprion clusters(active-stdby) into two..

if i were you, i would restore ucs if i want to revert back to active/standby configuration rather than changing to single device and leaving other ha setting. no this is not something I'm aiming to achieve.

 

I'm considering some option how to do this split the best way.. You've only changed the HA to SingleDevice and that's all. The GUI will hide probably all the HA/Redundancy/FAilover options once that changed, but you shown me that in conf files and probably in SCF all that HA config is still kept and only some flags has changed, so this is not the cleanest way especially thinking about someone else doing changes anytime later. This config might be a surprise on a SingleDevice system type for someone else later.

 

 

On the other hand if I start to remove everything I might casue production traffic interruption. I wonder for example how would all the floating IPs behave once you changed to SingleDevice ?

 

and If I would like to decomission them I would need to probablt do something like this:

 

- export SCF and then delete all of them, i.e from that SCF section:

 

 

shell write partition Common

 

self 1.2.3.4 {

 

netmask 255.255.255.0

 

unit 1

 

floating enable

 

vlan TEST_VLAN

 

allow all

 

}

 

(...)

 

 

and add a normal self IP for each deleted floating one, ie.:

 

 

self 1.2.3.4 {

 

netmask 255.255.255.0

 

vlan TEST_VLAN

 

allow all

 

}

 

and import that new SCF.

 

But I guess this may casue also service interruption since IP will be reconfigured (deleted and added again) ?

 

 

Thanks for continued support,
