Hi Fadia

You need HP ServiceGuard

and how could this serviceguard work with the shared storage do i need any thing such as CFS or vxvm , i want the two servers to see the same shared storage

[Siju Vadakkan]

To Activate the diskgroup in shared mode u have to go for CFS cluster.

Active/Standby indicates that you intend for the data to be seen by only one node at a time. Therefore, you need not purchase the CFS features in the Serviceguard Storage Management Suite (SG-SMS).
You may use either LVM or VxVM to configure storage devices for use with data.
If you do not need raw volume access, then basic Serviceguard will be sufficient for your needs.

Be advised that there are several flavors of Serviceguard, tailored to your needs. Start here:

http://h71028.www7.hp.com/enterprise/cache/6469-0-0-0-121.html

Look at the High Availability options:
» HP-UX 11i
» HP-UX 11i - HP Serviceguard Storage Management Suite
» Linux

If you have access to the HP document database in the ITRC, investigate emr_na-c00937283-3 which reviews the various bundles in SG-SMS.

If you decide that basic Serviceguard is sufficient, you need to create volume groups and logical volumes on the shared array, and 'vgimport' them into the other server.
Then you can create a SG cluster and application-oriented packages. The package can be application specific (read the manual) and you can also use the Enterprise Cluster Master toolkit
http://h71028.www7.hp.com/enterprise/cache/314511-0-0-225-121.html?jumpid=reg_R1002_USEN
that contains package implementation files for Oracle-specific packages.
