[root@cm01cel01 ∼]# cat /etc/resolv.conf

# Search domain and name server

search centroid.com

nameserver 11.11.1.250

Next, validate that your services are up by running the following command while logged in as root: [root@cm01cel01 ∼]# service celld status

rsStatus: running

msStatus: running

cellsrvStatus: running

[root@cm01cel01 ∼]#

Changing Compute Node Ethernet Networking

Each database server will need to be modified separately and manually.

1. First, log in as root on a compute node and use ipcalc to calculate the broadcast and network information for your new administration, client access, and additional networks:

[root@cm01dbm01 ∼]# ipcalc -bnm 10.16.1.10 255.255.255.0

NETMASK=255.255.255.0

BROADCAST=10.16.1.255

NETWORK=10.16.1.0

[root@cm01dbm01 ∼]# ipcalc -bnm 10.16.10.10 255.255.255.0

NETMASK=255.255.255.0

BROADCAST=10.16.10.255

NETWORK=10.16.10.0

[root@cm01dbm01 ∼]# ipcalc -bnm 10.16.20.10 255.255.255.0

NETMASK=255.255.255.0

BROADCAST=10.16.20.255

NETWORK=10.16.20.0

[root@cm01dbm01 ∼]#

2. With this information, you now need to manually edit the following files in /etc/sysconfig/network-scripts on each compute node and set the desired value for IPADDR, NETMASK, NETWORK, BROADCAST, and GATEWAY:

/etc/sysconfig/network-scripts/ifcfg-bondeth0

/etc/sysconfig/network-scripts/ifcfg-eth0

/etc/sysconfig/network-scripts/ifcfg-eth3
