Add node on MC Serviceguard with CA Eva

[StefanoC]

Hi guys,

 i have a simple question, it is possible to add a new node , "on the fly", to a MC Serviceguard 11.20 with CA Eva?

In the cluster ASCII file i have the definition of all VG.

Im not sure that can be done without stop all packages , because looking cmapplyconf manual it seems that when im trying to add a new node cluster check the avability of all VG in all nodes, but some VG is not active on stand-by site.

here the extract of cmapplyconf man:

           -k        Using the -k option means that cmapplyconf only checks
                     disk connectivity to the LVM volume groups that are
                     identified in the ASCII file. This option does not exit
                     on Linux. Omitting the -k option (the default behavior)
                     means that cmapplyconf tests the connectivity of all
                     LVM volume group on all the cluster nodes. Using -k can
                     result in significantly faster operation of the
                     command.  -k must be used with -C and can not be used
                     with -K

Thanks

Stefano

Hi Stefano,

Have a look, maybe it helps:

http://h30499.www3.hp.com/t5/Serviceguard/Can-the-cluster-be-up-when-doing-a-cmapplyconf/td-p/5274991

basically you can do the cmapplyconf while the cluster is up and ruunning, as the output of cmcheckconf has not complained and has actually told you it can do it.

Regards!
