we have got this error from time to time in our old AIX 6.1 (powerHA 6.1 GLVM) clusters. In deed last week we had to upgrade nodes from AIX 6.1TL6 to TL9 because a problem with clstat/cldump. But this is not your problem..
The steps we use here for all powerHA 6.1 clusters, sure are the same on your link above, are:
Hello,
I was wondering if I have 3 nodes (A, B, C) all configured to startup with HACMP, but I would like to configure HACMP in such a way:
1) Node B should startup first. After the cluster successfully starts up and mounts all the filesystems, then
2) Node A, and Node C should startup !

This post just as a follow-up for thread https://www.unix.com/aix/115548-hacmp-5-4-aix-5300-10-not-working.html: there was a bug in the clcomdES that would cause the Two-Node-Cluster-Configuration-Assistant to fail even with a correct TCP/IP adapter setup. That affected HACMP 5.4.1 in combinatin... (0 Replies)

Hi,
I have a IBM Power series machine that has 2 VIOs and hosting 20 LPARS.
I have two LPARs on which GPFS is configured (4-5 disks)
Now these two LPARs need to be configured for HACMP (PowerHA) as well.
What is recommended? Is it possible that HACMP can be done on this config or do i... (1 Reply)
Hi
I'm a little rusty with HACMP, but wanted to find out if it is possible to remove a disk heartbeat network from a running HACMP cluster.
Reason is, I need to migrate all the SAN disk, so the current heartbeat disk will be disappearing. Ideally, I'd like to avoid taking the cluster down to... (2 Replies)
As i have updated a lot of HACMP-nodes lately the question arises how to do it with minimal downtime. Of course it is easily possible to have a downtime and do the version update during this. In the best of worlds you always get the downtime you need - unfortunately we have yet to find this best of... (4 Replies)
Hi,
A customer I'm supporting once upon a time broke their 2 cluster node database servers so they could use the 2nd standby node for something else. Now sometime later they want to bring the 2nd node back into the cluster for resilance. Problem is there are now 3 VG's that have been set-up... (1 Reply)
Hi all,
I remember way back in some old environment, having the HA cluster services not being started automatically at startup, ie. no entry in /etc/inittab.
I remember reason was (taken a 2 node active/passive cluster), to avoid having a backup node being booted, so that it will not... (4 Replies)

sleep
sleep(3) Library Functions Manual sleep(3)NAME
sleep - Suspends execution for an interval of time
LIBRARY
Standard C Library (libc.a) Threads Library (libpthreads.a)
SYNOPSIS
#include <unistd.h>
unsigned int sleep ( unsigned int seconds );
STANDARDS
Interfaces documented on this reference page conform to industry standards as follows:
sleep(): XPG4, XPG4-UNIX
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies the number of seconds to sleep.
DESCRIPTION
The sleep() function suspends execution of a process for the interval specified by the seconds parameter. The suspension time may be
longer than requested due to the scheduling of other activity by the system.
In a multi-threaded environment, the sleep() function is redefined so that only the calling thread is suspended.
RETURN VALUES
If the sleep() function returns because the requested time has elapsed, it returns 0 (zero). If the sleep() function returns because it
caught a signal, the function returns the number of seconds remaining in the suspension.
