the problem occurs only if someone hijacks the service IP address...
is there a way i can disable in HACMP config that if there is a duplicate ip do not shutdown the system ? Duplicate IP After reboot
---------- Post updated at 12:18 PM ---------- Previous update was at 10:49 AM ---------- on another machine, there is another strange thing going on:
HACMP resources were not moved since the system went into non-responsive state and only when one system was manually switched off resources were moved to another server. Manually switched off from the panel.

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)
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)

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)
Few questions regarding Power HA ( previously known as HACMP) and VIOS POWERVM IVM ( IBM Virtualization I/O Server )
Is it possible to create HACMP cluster between two VIOS servers

Hello,
AIX 6.1 TL7 SP6
POwerHA 6.1 SP10
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.

Description
The routines and each interpret character strings representing numbers expressed in the Internet standard "." notation, returning numbers
suitable for use as Internet addresses and Internet network numbers, respectively. The routine takes an Internet address and returns an
ASCII string representing the address in "." notation. The routine takes an Internet network number and a local network address and con-
structs an Internet address from it. The routines and 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).
Return Values
The value -1 is returned by and for malformed requests.
