Change subnet SelfIP

Hello,

 

I would like to change the subnet of the selfip's from /24 to a /26. No ip's are used outside the /26 but I got an error that it is not possible to change the subnet mask. I tried it with the GUI getting this error.

 

01070601:3: A self IP matching the old network / mask 10.---.--.0%--- / 255.255.255.0 still exists in the configuration

 

So I tried to do it on the standby system and tried to delete them to recreate them but again no success as he doesn't allow me to delete as there would be IP addresses of servers with no selfip's defined for it.

 

Anyone a suggestion / solution for this.

 

Thx in advance,
