How to change wwid in HP-UX

[Sshahzeb]

I have slice one LUN from HSV300 Storage and mount on two servers which having oracle servicegurad cluster.

I want to mount one LUN(WWN = 0x600143800648e6910002200000d60000) on both node with same disk name (/dev/rdisk/disk50) and also same wwid as like other disk assign wwid and LUN number.

Please suggest me how to I do this.

How about Cluster-wide Device Special Files (cDSF)?

From LVM Guide:

HP-UX 11i Version 3, September 2010 Release introduces the support of cluster-wide device special
files (cDSF) for nodes running with Serviceguard, A.11.20.
A cluster device special files provides a consistent set of device special files across a set of cluster
nodes. The cluster device special files of a LUN will be the same on any node in a specified set
of nodes that share the LUN. The set of cluster nodes across which cluster device special files need
to be created can be specified using the cmsetdsfgroup command. The cluster device special
files can be displayed using the io_cdsf_config command. See the Managing Serviceguard
Eighteenth Edition manual for more detail on cluster device special files

I want to present as row disk which have same WWID and disk on both nodes.
