Cluster information
host01 information :
-          hostname=host01
-          ip= 172.10.10.10
-          virtual IP=172.10.10.11
-          heartbeat ip=No
-          eth0=172.10.10.10 (data no heartbeat)
-          eth1=Not use ,
-          vgshare=qasdatavg
lv=lvol1,lvol2
-          Oracle sid = QAS [Mcod csd,csq,bcd,bcq,j2d,j2q,ecd,ecq]
-          SAP sid = j2d,j2q,trex_90,trex_92
-          disk on qasdatavg= md0/md1/md2/md3/md4

Create OpenAIS cluster  
  1. Create a shared volume group.
  2. Create a OpenAIS Cluster.
  3. Create an application package.
  4. Dependency or Constraints of Resource cluster startup.
  5. Maintain cluster.

1.     Create a shared volume group


1.       Install multipath and configuration mpio/lvm

 (SLES 9 only) Changing system configuration
Using an editor of your choice, within /etc/sysconfig/hotplug set this value:
HOTPLUG_USE_SUBFS=no
On SLES:
rpm -ivh multipath-tools-0.X.X-XX.X.i586.rpm
On Red Hat:
rpm -ivh device-mapper-multipath-0.X.X-XX.elX.x86_64.rpm
- Load driver for the HBA is added to INITRD_MODULES in /etc/sysconfig/kernel
INITRD_MODULES="cciss reiserfs piix megaraid_sas mptspi siimage processor thermal fan jbd ext3 dm_mod edd dm-multipath qla2xxx"
- Ensure that boot.multipath and multipathd are set to start on boot: MPIO Services
chkconfig boot.multipath on
chkconfig multipathd on

The services can be started immediately with: 
/etc/init.d/boot.multipath start
/etc/init.d/multipathd start

To verify 
chkconfig --list | grep multipath

- Configuring multipath-tools  /etc/multipath.conf.
“failback 60”  # incase san not stable
Suse if the /etc/multipath.conf file does not exist, copy the example to create the file:
cp /usr/share/doc/packages/multipathtools/multipath.conf.synthetic /etc/multipath.conf
          Edit Backlist
blacklist {
devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st|sda)[0-9]*"
devnode "^hd[a-z][0-9]*"
devnode "^cciss!c[0-9]d[0-9].*"
}

- MD RAID Preconfiguration
chkconfig boot.md off
It is still possible to use local MD devices. These can be configured in the file /etc/mdadm.conf.localdevices,
which uses the same syntax as the /etc/mdadm.conf. The cluster tools RPM package contains a new initscript called boot.md-localdevices. Copy this file to the /etc/init.d directory and enable it using the command
chkconfig boot.md-localdevices on
- Using LVM2 on top of the MPIO devices
           modify/etc/lvm/lvm.conf

filter = [ "a|/dev/sda[1-4]|", "a|/dev/md.*|", "r|/dev/.*|" ]

- Reboot


2 Create md Configuration

Check DM multipath
 multipath -l
