Changing default route...

[boomer_2]

Hi guys,
I am just looking for some learned help here to change the network default gateway address easily with no network or operating disruption (preferably) to a running production system. Can this easily be done in SAM? Is it a default route change?
HP-UX v11i v2 or 11.23
Any help or recommendations appreciated.

Hi,
By hand you will be sure of the result, avoid SAM to do that.

just add your new default route
then remove the old one

route add default newaddress 1
route delete default oldaddress

change the default address in /etc/rc.config.d/netconf
ROUTE_DESTINATION[0]="default"
ROUTE_MASK[0]=""
ROUTE_GATEWAY[0]=""
ROUTE_COUNT[0]="1"
ROUTE_ARGS[0]=""

changing default route you need not to down the cluster.

[Laurent Menase]

no you don't need,
Once you remove the old default, all the intenal routes created for your connections will be flushed automatically.
A new internal route will be created on next packet sent, - just taking the default route, and if needed making a arp resolution of that new route

I means the internal routes using your old default queue will be flushed - not the one not using it of course -
