Is there any way to configure cluster and start cmcld daemon on one node (Serviceguard OPS Edition)with one heartbeat line? I think that it's not possible but maybe I'm wrong.

[Carlos Fernandez Riera]

Well ...

You can force to form a single node cluster using :
cmruncl -f

About hearbeat if there is not a second box the hearbeat take non sense.

Carlos,
I tryed to do this , it does not work , cmcld started successfully, but then died upon receiving abort signal (6).
I played a lot around cluster configuration file but it did not help

Yury:

I dont know now what is the problem but this is a entry point for others.

Good luck.

It is possible to configure a single node MC/SG OPS Edition cluster. just ensure that your networking is configured correctly, that each ip address configured reports correctly and use nslookup to confirm that the host name/ip address and ipaddress/hostname pairs match up.
what does the syslog show if this fails?
also make sure you have the lates patch for MC/SG. You do not state which version, so you will need to search on the patch database at this site for the correct patch.

Melvyn, sorry, I did not specify.
ServiceGuard OPS Edition A.11.09.
We have one node with one LAN line, and installed SGuard. Requirement is to install and run OPS, and it is needed to configure and run SG.
Syslog shows that cmcld started, then died upon signal 6. The coredump investigation shows that problem is in absent of shared library librescli.1 There is no any information about this library, what it is for, maybe it's created as a result of cluster form, I don't know.
I don't install patch yet , only took a look on patch PHSS_21996 that is recomended for this SG version, but I don't see resolution of one node problem. I'm not sure yet is it possible to install and run ServiceGuard on one node with only LAN.
thanx,
yury

It's possible. I did it
Thanks all for help

[melvyn burnard]

It would be nice for other users on the forums to know what the fix was for your problem. If possible please document what was the cause for your errors, and what you did to fix it.

[Yury Shipilov_1]

sure,
I'll do it at 01/13/01, i'm on vacation

You noted a dependency on librescli.1
That's found in the Event Monitoring Service files:
# find / | grep librescli
/etc/opt/resmon/lib/librescli.1
/etc/opt/resmon/lib/librescli.sl
/opt/resmon/lib/librescli.1
/opt/resmon/lib/librescli.sl

I suspect your EMS software wasn't up to date, or installed properly.

[Yury Shipilov_1]

ok,
initially problem looked like : is it possible to configure MCSG on one node with only LAN card.
1. I try to follow regular procedures using SAM or manually (see MCSG documentation) but cmcld daemon started and died
2. I did some investigation but no result (see above). But there is no any restriction on # of nodes in OPS installation documentation, so i continue.
3. I install PHSS_22540 patch but same result
4. I change MAX_CONFIGURED_PACKAGES parameter to 1 ,
and after this clcmd daemon started running.
That's all. Thanks again all who gave me the help,and clue. Thanks Stephen, for clue.
