10.Set up network services and conserver.
a. Network services:
i. DNS: Run makedns. Verify that DNS services are working for node resolution.
ii. (Optional) DNS: Add "nameserver=<service_ip>" to /etc/resolv.conf
iii. DHCP (Linux only): run makedhcp. Verify DHCP operational for hardware
iv. Verify that bootp is operational for booting the nodes.
b. Conserver:
makeconservercf
11.Start the HPC software daemons:
a. /opt/isnm/hdwr_svr/bin/hdwr_svr (hardware server)
b. Linux: service teal start (TEAL)
c. Linux: service teal_ll start (TEAL)
d. AIX: startsrc -s teal (TEAL)
e. AIX: startsrc -s teal_ll (TEAL)
f. /opt/isnm/cnm/bin/startCNMD (CNM)
g. GPFS
Setting up the operating system deployment environment
This optional step is required only when you want to use the new primary management node
to perform operating system (OS) deployment tasks.
Complete the following steps to use the primary management node to perform OS
deployment tasks:
1. Create operating system images:
For Linux: The operating system images definitions are already in the xCAT database, and
the operating system image files are already in /install directory.
For AIX: If the HANIM is used for keeping the NIM resources synchronized, manual steps
are not needed to create the NIM resources on the standby management node.
Otherwise, the operating system image files are in the /install directory, but you must
create the NIM resources manually.
Complete the following steps to re-create the NIM resources manually:
a. If the NIM master is not initialized, run command "nim_master_setup -a
mk_resource=no -a device=<source 'directory>" to initialize the NIM master, in which
the <source 'directory> is the directory that contains the AIX installation image files.
b. Run the following command to list all the AIX operating system images:
c. For each osimage:
i. Create the lpp_source resource:
