Trying to add a global route to cluster configuration

[ronbarak]

Hi Guys,

I'm trying to add a global route to cluster configuration. I added the following RouteOptions to my Linux VCS main.cf:

       MultiNICA EdnMNIC (

               Device @ronbgmc1a = { eth2 = "10.107.68.24", eth3 = "10.107.68.25" }

               Device @ronbgmc1b = { eth2 = "10.107.68.26", eth3 = "10.107.68.27" }

               NetMask = "255.255.255.0"

               RouteOptions = "-host 10.107.3.223 eth2"

               PingOptimize = 0

               NetworkHosts = { "10.107.68.1" }

               )

Using the following commands:

[root@ronbgmc1b root]# hastop -all -force

[root@ronbgmc1b root]# pushd /etc/VRTSvcs/conf/config/

/etc/VRTSvcs/conf/config ~

[root@ronbgmc1b config]# vi main.cf

[root@ronbgmc1b config]# hacf -generate .

[root@ronbgmc1b config]# grep Route ./main.cf

               RouteOptions = "-host 10.107.3.223 eth2"

[root@ronbgmc1b config]# hastart

However, the new route is not added to the routing table:

[root@ronbgmc1b config]# netstat -nr

Kernel IP routing table

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface

10.107.68.0     0.0.0.0         255.255.255.0   U         0 0          0 eth2

0.0.0.0         10.107.68.1     0.0.0.0         UG        0 0          0 eth2

[root@ronbgmc1b config]#

Can anyone suggest the correct procedure of adding a route to VCS ?

Thanks,

Ron.

The Bundled Agents Reference Guide has this:
Assignment of a base IP address to a device is followed by a route add command with the options specified for this attribute. RouteOptions are applicable only when configuring the local host as the default gateway.

Perhaps this is the problem.

Hi Gene,

Thanks for the prompt answer.

“Digging” further, I managed to deduce that one can add a route to a host using the following command (below is the full session showing that the route was indeed added):

hares -modify EdnMNIC RouteOptions "1.2.3.4"

Bye,

Ron.

The procedure to add the route to main.cf (assuming IP address is 1.2.3.4):

[root@ronbgmc1b config]# netstat -nr

[root@ronbgmc1b config]# pushd /etc/VRTSvcs/conf/config

[root@ronbgmc1b config]# haconf -makerw

[root@ronbgmc1b config]# hares -modify EdnMNIC RouteOptions "1.2.3.4"

[root@ronbgmc1b config]# hares -modify EdnMNIC Enabled 1

Notes:

1. The format for the hares -modify RouteOptions command above is not according to Veritas manuals (which didn’t work for me, probably because of what you wrote in your message).
2. I defined the route to be glbal, meaning it is active on all CVS nodes.
