I am new to HACMP V5.4 in AIX5.3.Please let me know how to get the virtual IP address configured for a HACMP cluster.
Is this the correct way to identify it?

Thanks in Advance (3 Replies)

PHYS(2) System Calls Manual PHYS(2)
NAME
phys - allow a process to access physical addresses (2BSD)
SYNOPSIS
phys(segreg, size, physaddr)
unsigned int segreg, size, physaddr;
DESCRIPTION
The argument segreg specifies a process virtual (data-space) address range of 8K bytes starting at virtual address segregx8K bytes. This
address range is mapped into physical address physaddrx64 bytes. Only the first sizex64 bytes of this mapping is addressable. If size is
zero, any previous mapping of this virtual address range is nullified. For example, the call
phys(7, 1, 0177775);
will map virtual addresses 0160000-0160077 into physical addresses 017777500-017777577. In particular, virtual address 0160060 is the
PDP-11 console located at physical address 017777560.
This call may only be executed by the super-user.
ERRORS
[EPERM] The process's effective user ID is not the super-user.
[EINVAL] Segreg is less than 0 or greater than 7.
[EINVAL] Size is less than 0 or greater than 128.
SEE ALSO
PDP-11 segmentation hardware
BUGS
On systems with ENABLE/34(tm) memory mapping boards, phys cannot be used to map in the I/O page.
This system call is very dangerous. It is not considered a permanent part of the system.
Phys is unique to the PDP-11 and 2BSD; its use is discouraged.
