Veritas Cluster LLT issue

[spoodie]

I'm attempting to set-up a cluster between two machines and I'm getting a problem with the LLT on one of the servers. When I try to startup the LLT manually I get the following errors:

jack-# /sbin/lltconfig -c -o
LLT:lltconfig:15336: dlatt failed: DLerror 8 - Error 0
LLT:lltconfig:15074: cannot DL_ATTACH 0 on /dev/qfe

We're using VCS 1.3.0.

Any ideas would be appreciated.

Thanks,


Seth

The LLT interfaces must not be in use by TCP/IP - do not create a /etc/hostname.xx file for them.

What does your file /etc/llttab contain?

Can you call lltstat -nvv and see what it says

I'm using a QFE card for the private network and hme0 for connection to the rest of the network. I've checked and none of the QFE ports are configured for TCP/IP.

Contents of the llttab:
jack-# cat /etc/llttab
set-node jack
#set-cluster 0
link qfe0 /dev/qfe:0 - ether - -
link qfe3 /dev/qfe:3 - ether - -
start

And the output of the lltstat -nvv:
jack-# /sbin/lltstat -nvv
LLT node information:
Node State Link Status Address
* 0 jack OPEN
1 sam IDLE
2 IDLE
3 IDLE
...
(and so on to line 31)

This confuses me as it says jack is OPEN. Any further ideas?

Thanks in advance.

Has this ever worked? I'm assuming that you installed the private network first and then the VCS software using the InstallVCS command with a cluster ID of 0 and servers jack and sam - I don't understand why the set-cluster line is commented out in your config file. When installing VCS you need to ensure that root on jack can rsh to root on sam - check /.rhosts file. If this worked there should be a file /etc/llthosts containing jack and sam on both servers as well as a similar /etc/lltab on sam.

There could be an issue if you have a switched private network - recommendation is to use direct connections or a hub or VLAN for each of the 2 connections.

If you're on solaris 2. or earlier you will need to reboot before LLC will work.

Check the kernel modules are loaded
