HPUX : Deactivate AUTO_VG_ACTIVATE in cluster aware Env

On node A and B are in cluster.

AUTO_VG_ACTIVATE=1 --Non cluster

AUTO_VG_ACTIVATE=0 -- Cluster Environment.

Both nodes have AUTO_VG_ACTIVATE=1  - this implies that ALL volume groups defined in the /etc/lvmtab are not part of a high availability cluster, “Cluster Aware”, and should be activated at boot (vgchange –a y /dev/vg_name).

   

  This is not the correct configuration for a volume group, that is “Cluster Aware”.  The Serviceguard package named “acms” uses /dev/vg04, /dev/vg04 has 27 logical volumes. The volume group activation, file system checks (fsck) and subsequent mounting/un-mounting of the file systems that reside on the logical volumes are all controlled by serviceguard package control script.

 

Your current configuration, at boot, tries to activate /dev/vg00, /dev/vg01 and /dev/vg04.

 

 

/etc/lvmrc should have  AUTO_VG_ACTIVATE=0  and the following custom_vg_activation stanza modified to include for non-Cluster Aware volume group activation, such as /dev/vg00 and /dev/vg01 –

 

Original custom_vg_activation stanza

custom_vg_activation()

{

        # e.g. /sbin/vgchange -a y -s

        #      parallel_vg_sync "/dev/vg00 /dev/vg01"

        #      parallel_vg_sync "/dev/vg02 /dev/vg03"

             

 

        return 0

}

Modified custom_vg_activation stanza

________________________________

 

#

 

custom_vg_activation()

{

        # e.g. /sbin/vgchange -a y -s

        #      parallel_vg_sync "/dev/vg00 /dev/vg01"

        #      parallel_vg_sync "/dev/vg02 /dev/vg03"

             

               /sbin/vgchange -a y /dev/vg00

              /sbin/vgchange -a y /dev/vg01

 

        return 0

}

The result of making this change is that /dev/vg00 and /dev/vg01 will be available at system boot, /dev/vg04 will not be available at system boot. The serviceguard package control script will make /dev/vg04 available when the acms package is started through serviceguard.
