np with that, ideally add the new HB network before removing the old one.
Make sure you have PV IDs assigned to the new HB disk and known to both systems, run a discovery from within HACMP and create the new disk HB network. Once you then synchronize the cluster, the new HB network becomes active. You can then go ahead and remove the old disk HB network, synchronize again and you are done.
But, sooner or later I'd schedule some downtime to sort out the LUN numbering, to have it continuous again from hdisk0 up. As long as you work with the system its ok, but imagine someone else (not knowing how big your organization is) works with the system, removes all drives and cfgmgr's them again in, they will be differently named. HACMP is stupid though and does not rely on the PVID, but the hdisk name. The previous HB disks are gone/renamed, you waste time on troubleshooting why the cluster doesn't start...

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)

NAME
ha_logd - Logging Daemon for High-Availability Linux
SYNOPSIS
ha_logd [-s] [-k] [-d] [-h] [-c file]
DESCRIPTION
ha_logd is a logging daemon for Linux-HA. It receives messages from a local domain socket /var/lib/heartbeat/log_daemon, and writes them to
appropriate files and syslog if enabled. The reason for utilizing this logging daemon is that occasionally Heartbeat suffers from disk I/O
delays. By sending log messages to a logging daemon, heartbeat can avoid such I/O delays.
OPTIONS
The following options are supported:
-s
Show ha_logd status (either running or stopped)
-k
Stop (kill) the daemon
-d
Daemonize (without this option, ha_logd will run in the foreground)
-h
Show a brief usage message
-c file
Configuration file. You may configure a regular log file, debug log file, log facility, and entity. For details, see the example
ha_logd.cf file found in the documentation.
FILES
o /var/run/ha_logd.pid - PID file
o ha_logd.cf - example configuration file
