Hi,

from ur above O/p it seems that problem is related to network.untill u fix it u will not be able to configer the cluser.
1)cluser configeration file for lan inetrfaces. its configerd properly or not
2)check switch connections
3)check connectivity using linkloop command


Regards

Hi,

IF you see the output you attached here..it clearly shows that which areas you need to check to fix the issue.

It seems basic requirement for SG are missing here.

>> Lock VG configuration
>> Network configuration (public lan and heartbeat lan)

Why it is saying only 1 VG each on your SG nodes...

Can you provide some more details what all did to set this up?

Let's break the discrepancies into separate items.
Issue 1:
Gathering storage information
Found 1 devices on node iocci101
Found 8 devices on node iocdb101

Apparently /etc/lvmtab does not present the same number of disks for each shared volume group.
Perhaps you should investigate the vgexport/vgimport process. The following 2 lines confirm this:


Volume group /dev/vglock is configured differently on node iocci101 than on node iocdb101
Volume group /dev/vglock is configured differently on node iocdb101 than on node iocci101

Issue 2:
Gathering network information
Beginning network probing (this may take a while)
Completed network probing
Non-uniform connections detected,
iocci101 lan900 10.51.10.12 successfully received from iocdb101 lan901 10.51.11.10
but iocdb101 lan901 10.51.11.10 did not receive from iocci101 lan900 10.51.10.12.
This could be due to heavy network traffic, or heavy load or routing configuration on iocci101.

with discovered configuration information.

A network configuration problem exists. I suggest you attempt a 'linkloop' test between lan901 on iocdb101 with lan900 on iocci101 in both directions.
The proper format of the command is:
# linkloop -i
Example:
# linkloop -i 0 (lan0/lan900) 0x0011855F12A2

check network card connectivity using linkloop

linkloop -i

Hi,
Check the LAN interfaces communitation with linkloop from both node.
Then try
