Managing Serviceguard Extension for SAP, December 2007

Step-by-Step Cluster Conversion
Cluster Configuration
Chapter 3 143
OS450 Optional Step:
For non-CFS shares, it is recommended to set AUTO_VG_ACTIVATE=0 in
/etc/lvmrc. Edit the custom_vg_activation() function if needed.
Distribute the file to all cluster nodes.
OS460 Optional Step:
It is recommended to set AUTOSTART_CMCLD=1 in
/etc/rc.config.d/cmcluster. Distribute the file to all cluster nodes.
IS470 Installation Step:
Define volume groups, logical volumes, IP addresses and subnets in the
package control scripts <pkg_name>.control.script.
Fill the IP[*] and SUBNET[*] array with the IP addresses and subnet
addresses that the package is attached as well.
When using the HP Serviceguard Storage Management Suite with CFS
and shared access Option 3 (Chapter 2 – Planning the Storage Layout)
the definition and configuration of logical volumes in the package control
script might not be necessary for the SAP components. The CFS based
file systems are made available through the corresponding multinode
packages as defined in Chapter 2 – Planning the Storage Layout. For
non-CFS shares, the volume groups are directly connected to the SAP
packages. The file systems that are specified in the LV[*], FS[*] and
FS_MOUNT_OPT[*] array in this case are not identical to the file
systems that are for HA NFS usage. For example:
LV[0]="/dev/vgdbC11/lvoracle"; FS[0]="/oracle/C11";
FS_MOUNT_OPT[0]="-o rw"
LV[1]="/dev/vgdbC11/lvsapmnt"; FS[1]="/export/sapmnt/C11";
FS_MOUNT_OPT[1]="-o rw"
LV[2]="/dev/vgC11/lvusrsap"; FS[2]="/usr/sap/C11/DVEBMGS20";
FS_MOUNT_OPT[2]="-o rw"
LV[3]="/dev/vgsapnfs/lvtrans";
FS[3]="/export/usr/sap/trans"; FS_MOUNT_OPT[3]="-o rw"
