cmquerycl problem

Domenico_5 — Tue, 13 May 2003 22:00:50 GMT

Hi guys

I'm trying to create a cluster with two server, each one with 3 lans.
When i try cmquerycl -v -n node1 -n node2 -C cluster.ascii I can generate the conf file but without the backup lan.

I have configured two lans for each server and one non configured for backup, but I cant see it from any node.

All work correctly rlogin, vgexport/vgimport and so on.

S.O. 11.11 MCSG 11.14

'cmquerycl' relies upon MAC addresses to determine heartbeat and data LANs so start collecting MAC addresses with 'lanscan' and 'arp -a' and then testing for connectivity with 'linkloop MAC'.

More then likely you've got a duplex disconnect with a switch port. If you have a known working port move your cable over to there.

Use 'lanadmin' for your setting your own NICs. I.e.,

lanadmin -x 4
lanadmin -X 100FD 4
lanadmin -X 10HD 4, etc.

If you can successfully test for connectivity using MAC addresses then so can 'cmquerycl'. 'ping'ing is next but only a nice to know bit of information and irrelevant with switches.

hi michael

I have connect all port on a hub and I don't have any disconnection, all work fine.

if I run lanadmin -x 0,1,2 all driver are correct.

what I can try?

Let us see your ascii file that gets created.
Also do netstat -in on each system and post it here.

You can now run 'cmcheckcl', which should accept the ascii file but what you're seeing is normal.

cmcheckconf -C /etc/cmclustercl/conf.ascii

cmruncl

cmviewcl -v

cmscancl -v -o /tmp/file

The lan2 (stby) may have been assigned an inappropriate subnet mask, and IP of 0.0.0.0 or some odd thing like that. Try this:

# ifconfig lan2 unplumb

then

# ifconfig lan2 plumb

Check /etc/rc.config.d/netconf to insure no assignment is made to lan2 at boot time.

Verify lan2 has connectivity to the intended primary lan:

# linkloop -i

Hmm, so the lan2 is there, but the ascii file does not, as you say, have it defined.
This means that there is no connectivity between the configured lans and the standby
You need to do a check with linkloop to see whether this is so.
if they are not connected, SG will ignore this lan.

if you are using N/L/rpXXX class servers be sure you have connected the LAN cable to the correct cards and not on the LAN console / GSP position. Check your cabling,
switch - VLAN config as well.

Just an idea

SOLVED!!!!

It's an hardware problem, on slot 4 and 3 i have: (3) fc card (66Mhz) (4) 100bt. (33Mhz).

I have changed the lan card with 1Gbit (66Mhz) and all work fine!!

Tnx to all for your consulence
