cluster configuration

Hi
i am trying to configure two node cluster
OS 11i
SG: 11.16
Patch level for cluster (PHSS_31071)
when i try to query cluster info i receive the following info:

"Error: Node Lab2 is refusing Serviceguard communication.
Please make sure that the proper security access is configured on node
Lab2 through either file-based access (pre-A.11.16 version) or role-based
access (version A.11.16 or higher) and/or that the host name lookup
on node Lab2 resolves the IP address correctly.
Failed to gather configuration information."


Any Idea ?

Regards
Hassoun

Re: cluster configuration

Hi,

Did you put the nodes in /etc/cmcluster/nodelist.

Re: cluster configuration

Hi Hassoun,

I thought so. The solution is a reboot of 1 of the nodes or put the following patches in place. PHCO_27957
PHCO_30698
PHKL_30516
PHKL_31162
PHKL_32619
PHSS_32573
PHSS_32731
PHSS_32732
after this tyhe cluster must be right.

grtz. Mark

Please take a read of the following documents, as these may help due to the new security features of SG 11.16:

Re: cluster configuration

Hi,
To more clarify things, I created the cmclnodelist, put the nodes in /etc/hosts, also in /.rhosts but as mentioned before I had the error message.
I tried to disable identd, so i added the -i option to cmomd and the tcp cmclconfd , then i restart the inetd, but also still have the same error message.
I restart the 2 nodes, when checking the syslog I notice this message:" cmclconfd[1467]: Unable to stat /etc/cmcluster/cmclconfig,
No such file or directory "

Re: cluster configuration

The message "Unable to stat /etc/cmcluster/cmclconfig,"
simply indicates that there is no cluster binary to be found, which is to be expected as you have not yet created a cluster and so there is no binary.
I would suspect you still have some form of networking configuration issue, so check this out thoroughly, using the previously mentioned documents to assist you.
Also make sure inetd is running ok.

Re: cluster configuration

Hi

I had the same problem as well. The reason is a typing error in /etc/hosts file. make sure the host name, IP address are correct.

In addition, run cmquerycl as root then you do not need to worry about the acl.

thanks

Re: cluster configuration

hi, hassoun.

the same problem was on my cluster. i've reboot systems and run this command:

cmquerycl
#this discover the cluster's nodes over the network

cmquerycl -C /etc/cmcluster/conf.my -n Node_1 -n Node_2
# this creates conf file for my cluster

of course, these nodes was written in /etc/.rhosts

it's helps.

Re: cluster configuration

Run cmscancl command. This will give you possible network errors if there is any.

Good Luck..

Re: cluster configuration

hi Hassoun,

The node names entered in the cluster ascii file will be incorrect. This issue is usually a invalid host/node name or IP address.

1) Check the node name
# uname -n

2) Verify the correct node name and IP address is in the /etc/hosts file.

3) Enter the correct node name and IP into the cluster ascii file as shown
below.


NODE_NAME Lab1
NETWORK_INTERFACE lan0
HEARTBEAT_IP 10.10.10.1
NETWORK_INTERFACE lan1
HEARTBEAT_IP 192.168.193.15
NETWORK_INTERFACE lan2
FIRST_CLUSTER_LOCK_PV /dev/dsk/c4t1d0

NODE_NAME Lab2
NETWORK_INTERFACE lan0
HEARTBEAT_IP 10.10.10.2
NETWORK_INTERFACE lan1
HEARTBEAT_IP 192.168.193.14
NETWORK_INTERFACE lan2
FIRST_CLUSTER_LOCK_PV /dev/dsk/c4t1d0


4) Verify the cluster ascii file with cmcheckconf
# cmcheckconf -v -C cluster.ascii

5) Apply the cluster ascii file with cmapplyconf
# cmapplyconf -v -C cluster.ascii

6) Start the cluster with cmruncl
# cmruncl

All the Best !!!
