I am looking at going the route of a takeover\giveback to reconfigure these settings. We've done numerous maintenance windows over the years with a takeover\giveback for both nodes and the only hiccups seen are on a couple of iSCSI connected SQL clusters, NFS virtual machines keep humming right along.rfrfr
So I should do a takeover of one node first and then modify its /etc/rc file? I've always modified the /etc/rc file first and then initiated a takeover. Is that not the correct way? What is the negative of modifying the /etc/rc file first and then taking over the node?
This is the current running /etc/rc file:
hostname ****************
ifgrp create lacp ifg03 -b ip e0a e0b
ifgrp create lacp ifg04 -b ip e1a e1b
vlan create ifg03 61
vlan create ifg04 61
ifconfig e0M `hostname`-e0M flowcontrol full netmask 255.255.255.0 partner e0M
ifconfig ifg03-61 `hostname`-ifg03-61 netmask 255.255.255.0 partner ifg01-61 mtusize 1500 trusted -wins
ifconfig ifg03-61 alias 10.16.1.65 netmask 255.255.255.0 broadcast 10.16.1.255
ifconfig ifg04-61 `hostname`-ifg04-61 netmask 255.255.255.0 partner ifg02-61 mtusize 9000 trusted -wins up
ifconfig ifg04-61 alias 10.16.1.67 netmask 255.255.255.0 broadcast 10.16.1.255
route add default 10.16.1.10 1
routed on
options dns.domainname ******************
options dns.enable on
options nis.enable off
savecore
Modifying it would look like this:
hostname *************
ifgrp create lacp ifg03 -b ip e0a e0b
ifgrp create lacp ifg04 -b ip e1a e1b
vlan create ifg03 61
