Start cmcld

[Eudo Jimenez_2]

Please

I need to change a vg in order to configure a clsuter but this happen

vgchange -c y /dev/vgmdsapp
vgchange: Cluster Services not available or unreachable on this system, for volume group "/dev/vgmdsapp".


How a start cmcld demon?

[A. Clay Stephenson]

cmrunnode.

Man cmrunnode for details.

[Jeff_Traigle]

Looks like the node isn't configured to start the node at boot time. Not uncommon. Just run "cmrunnode" and it should join the cluster so you can do what you need to do (assuming it was properly added to the cluster already).

[Carlos Roberto Schimidt]

If you want configure automatic startup, change "AUTOSTART_CMCLD=1" in file
/etc/rc.config.d/cmcluster.

While run cmrunnode, run:
# tail -f /var/adm/syslog/syslog.log

lookink for any error message

[Eudo Jimenez_2]

this is my real situation,

I am configuring the first node because the second one is not yet available...

Can I go ahead with this?

.- Create configuration file (cmclconfig.ascii)

.- Generate the binary configuration file

.- vgchange -c y for al vg´s

Hi,

Yes you can. Start / test the cluster using
# cmruncl -v -n

Ok, the lan3 and lan4 are HEARTBEAT_IP and does not has conected cable, is this the reason because DLPI level failed?

cmruncl -n

cmrunnode only helps a node join a cluster that is already up and running.

[Stephen Doud · Accepted solution]

Yes.... when a NIC is NOT connected but listed in the cluster ASCII file, cmcheckconf and cmapplyconf will fail.
Until they are connected, comment any references to them out of the ASCII file.
