Detected a partition of IP subnet 192.168.1.0

[srinimar]

i got the below error while doing cmcheckconf..

# cmcheckconf -C chdcls.ascii
Begin cluster verification...
Note : a NODE_TIMEOUT value of 2000000 was found in line 127. For a
significant portion of installations, a higher setting is more appropriate.
Refer to the comments in the cluster configuration ascii file or Serviceguard
manual for more information on this parameter.

any suggestions on this..if you need any more details ...i can ..

you have something in your network that has partitioned these two LAN's into separate physical segments.
Thsi could be a cable, a switch configuration, subnet masks etc.

Shalom sri,

If this network is not what you wish in your cluster, check /etc/rc.config.d/netconf

You need to have networking solid before cmquercl is run.

Make sure there are no binary cluster configuration files present.

these are the entries in netconf files..

Server 1
-------
#SG Heart Beat#####

#SUBNET_MASK[5]="255.255.255.0"
#BROADCAST_ADDRESS[5]="192.168.1.255"
#INTERFACE_STATE[0]=""
#DHCP_ENABLE[5]=0


Server 2
-------
#SG Heartbeat IP #####
#IP_ADDRESS[1]="192.168.1.123"

I have attached some IP's info as well..

[melvyn burnard]

so hav eyou chedcked your switch ports/cables/LAN NIC's?

[srinimar]

I am able to SSH, telnet and ping these two servers. i dont have any othet network prob. here. what could be the reason here geeting the above error while using cmcheckconf on .ascii file.

can any one help me on this..

[srinimar]

I have my server Ip configured on Lan0 NIC and heartbeat IP on Lan1 NIC.

the cables from Lan0 are connected to switch and switch to router..

I dont have any cables from lan1 so here am I missing something....

[Stephen Doud]

Is lan1 a supported NIC for Serviceguard?
What does 'model' report?
I note that lan1, on both servers is on path 0/1/2/1 - is this the built-in LAN? Some built-in NICs are not supported with Serviceguard.

If the NIC is supported, then try performing a simple linkloop between lan1 NICs.

Syntax:
# linkloop -i
Get the PPA and MAC from 'lanscan'.
The PPA = the Crd In# in that output.


If linkloop works, then determine whether DLPI protocol is being blocked between the NICs, ie, on the switch that connects the two NICs. You may want to try using a cross-over cable btwn lan1 NICs to eliminate that potentiality - and see if the symptom disappears.
