I would like to know if anyone has faced this problem. Whenever there is a duplicate IP address, HACMP goes down infact HACMP ( PowerHA ) takes the whole system down.
Hi All,
As per the IBM upgrade/support matrix

Hello,

I was experimenting with new hacmp build. It's 3-node cluster build on AIX 6.1 lpars. It contains Ethernet and diskhb networks. Shared vg disk is SAN disk. Two nodes see disk using vscsi, third node sees disk using npiv. Application is db2 server.

I am planning for building a new database server using AIX 6.1 and Oracle 11.2 using ASM.
As i have learned starting with Oracle 11.2 ASM can only be used in conjunction with Clusterware, which is Oracles HA-software. As is the companies policy we do intend to use PowerHA as HA-solution instead... (1 Reply)
hi,
when I do a failover, hacmp always starts db2 but recently it fails to start db2..noticed the issue is db2nodes.cfg is not modified by hacmp and is still showing primary node..manually changed the node name to secondary after which db2 started immediately..unable to figure out why hacmp is...

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?
If i give ifconfig -a the first ip address displayed is the real address of the host.So the other one can be VIP.
Thanks in Advance (3 Replies)
Hi, I try to understand how to configure my ethernet network in a hacmp cluster.
I have 2 nodes, 3 lan port on each node, and 1 service ip to cluster.
I don't have any serial o iscsi heartbeat.
Do you suggest me a possibile ip address configuration? I've many error whene I verify it from hacmp... (3 Replies)
INET(3N)INET(3N)NAME
inet_addr, inet_network, inet_ntoa, inet_makeaddr, inet_lnaof, inet_netof - Internet address manipulation routines
SYNOPSIS
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
unsigned long inet_addr(cp)
char *cp;
unsigned long inet_network(cp)
char *cp;
char *inet_ntoa(in)
struct in_addr in;
struct in_addr inet_makeaddr(net, lna)
long net, lna;
long inet_lnaof(in)
struct in_addr in;
long inet_netof(in)
struct in_addr in;
DESCRIPTION
The routines inet_addr and inet_network each interpret character strings representing numbers expressed in the Internet standard "." nota-
tion, returning numbers suitable for use as Internet addresses and Internet network numbers, respectively. The routine inet_ntoa takes an
Internet address and returns an ASCII string representing the address in "." notation. The routine inet_makeaddr takes an Internet net-
work number and a local network address and constructs an Internet address from it. The routines inet_netof and inet_lnaof break apart
Internet host addresses, returning the network number and local network address part, respectively.
All Internet address are returned in network order (bytes ordered from left to right). All network numbers and local address parts are
returned as machine format integer values.
INTERNET ADDRESSES
Values specified using the "." notation take one of the following forms:
a.b.c.d
a.b.c
a.b
a
When four parts are specified, each is interpreted as a byte of data and assigned, from left to right, to the four bytes of an Internet
address. Note that when an Internet address is viewed as a 32-bit integer quantity on the VAX the bytes referred to above appear as
"d.c.b.a". That is, VAX bytes are ordered from right to left.
When a three part address is specified, the last part is interpreted as a 16-bit quantity and placed in the right most two bytes of the
network address. This makes the three part address format convenient for specifying Class B network addresses as "128.net.host".
When a two part address is supplied, the last part is interpreted as a 24-bit quantity and placed in the right most three bytes of the net-
work address. This makes the two part address format convenient for specifying Class A network addresses as "net.host".
When only one part is given, the value is stored directly in the network address without any byte rearrangement.
All numbers supplied as "parts" in a "." notation may be decimal, octal, or hexadecimal, as specified in the C language (i.e., a leading 0x
or 0X implies hexadecimal; otherwise, a leading 0 implies octal; otherwise, the number is interpreted as decimal).

DIAGNOSTICS
The value -1 is returned by inet_addr and inet_network for malformed requests.
BUGS
The problem of host byte ordering versus network byte ordering is confusing. A simple way to specify Class C network addresses in a manner
similar to that for Class B and Class A is needed. The string returned by inet_ntoa resides in a static memory area.
Inet_addr should return a struct in_addr.
