AIX HACMP Startup Procedure

Purpose:

This document describes steps to start and stop IBM HACMP cluster.

Startup Procedure:

Phase1: Powering on the servers and bringing up AIX.

Caution: Do NOT power on both the servers simultaneously.

BEGINNING of phase1:

1) Power on all peripherals.If any of the peripherals is already on, leave it as it is.

2) Power ON node1 server.

3) Wait till the Common Desktop Environment (CDE) screen is displayed in the monitor display of this server.

4) Power ON node2 server.

5) Wait till the Common Desktop Environment (CDE) screen is displayed in the monitor display of this server.

END of phase1


Phase2: Bringing up cluster (HACMP):

Caution: Do not login now through CDE. Through out this procedure use only command line login.

BEGINNING of phase2:

1)login as : root

2) Checks to see that the cluster is not running:
a)

# lssrc -g cluster

Subsystem Group PID Status

b)

# netstat -i

c)

# lsvg -o

rootvg

3) Check to see if network is working:
a)

# ping node2_boot
# ping node2_stdby
# ping node2_prv

4) Start HACMP:

# smitty clstart

Start Cluster Services

Type or select values in entry fields.

Esc+0 to exit to prompt.

To see the progress of cluster startup:

# tail -f /tmp/hacmp.out

When no more update takes place, the cluster is fully up on this system.

5) Check if cluster is up and normal:
a)

# lssrc -g cluster

Subsystem Group PID Status
clstrmgrES cluster 12762 active
clsmuxpdES cluster 14672 active
clinfoES cluster 15570 active

b)

# netstat -i

c)

# lsvg -o

othervg
rootvg

END of phase2:
Cluster is ready.
