Release 4.5, Revision 2

Aftersetting up ssh and scp for your cluster, follow these steps to conﬁgure HA HPSS to use them:

1. Edit the/var/hahpss/hpss_environment ﬁle on either of the cluster nodes, and set the

following environment variables:

HPSS_REMOTE_SHELL=ssh

HPSS_REMOTE_COPY=scp

2. Now synchronize this change to the other node:

% ./hpss_sync.ksh <other_node>

Ifssh was installed and conﬁgured properly (and if the sshd was started on both nodes) the above

steps will complete your conversion to anssh-enabled HA HPSS system.

G.9 Important Information

When using HACMP to manage shared resources, there are many differences from a normal AIX

systemthat must be taken into account. Addressing all these differences is beyond the scope of this

document but it nonetheless very important. It is an absolute necessity that administrators

familiarize themselves with the HACMP for AIX Administration Guide in order to understand

these issues.

Forexample, updating volume groups and ﬁle systems will have to be done using HACMP’s SMIT

menus, not the normal LVM commands. Otherwise, the ODMs on the two cluster nodes will get

out of sync.

For the most helpful troubleshooting advice, see theHACMP for AIX Troubleshooting Guide.

G.10Routine HA Operations

G.10.1 Startup the Cluster

To start the HACMP cluster (the HACMP Cluster Manager) on the cluster nodes, there are two

methods.

1. The ﬁrst method is the most convenient; however, it can only be used ifrsh is enabled. It

allows the Cluster Manager to be started on both nodes with a single command:

% smitty hacmp

Cluster System Management

-> HACMP Cluster Services

-> Start Cluster Services
