Re: How can modify the boot of tru-cluster

Hi,

I'm not sure that I entirely understand the question...

What do you want to prevent from starting ?

The usual start up scripts on Tru64 can be found under /sbin/rc3.d which are usually links to scripts /sbin/init.d

Re: How can modify the boot of tru-cluster

Hi,

in the /sbin/rc3.d I have the next scripts:
>cd /sbin/rc3.d
>ls -l S*clu*
S00clu_min -> ../init.d/clu_min
S15clu_alias -> ../init.d/clu_alias
S15clu_caa -> ../init.d/clu_caa
S28clu_mid -> ../init.d/clu_mid
S57clustercron -> ../init.d/clustercron
S99clu_max -> ../init.d/clu_max

I have to disable all scripts?

I don't know, because I don't understand what you're trying to achieve...

I need that when I reboot the machine does not start any cluster service.

Re: How can modify the boot of tru-cluster

If I am correct in understaning your problem
you will have to remove machine from cluster

#clu_delete_member -m memb_id

reboot the machine and it would come up in non cluster mode.

You will have to add the member back to cluster after your motto is finished.

#clu_add_member -c member_config_file

I would suggest to have backup if you do not have much hands-on with Tru-cluster, cause its best cluster but not very simple to diagnose.

Re: How can modify the boot of tru-cluster

do you really don't want the system to be part of the cluster?
or do you mean the system must not start any cluster resources?
in the last case you can modify the HOSTING_MEMBERS entry in /var/cluster/caa/profile/
to not enable cluster resources on this host.
after modification you'll need caa to update the registration of the resource.

The node remains part of the cluster, and can access cluster filesystems, but will not automatically start any resources under control of caa.
(you can still start them manually)
