Configuration Example

The following example configuration uses shared and local file system host files for this Sun QFS shared file system setup. To communicate with metadata clients that are outside the Oracle Solaris Cluster, you must establish the Sun QFS metadata traffic over the Sun QFS network. Because the metadata client is not a member of the Oracle Solaris Cluster configuration, use a logical host for this traffic. In the example configuration, sc-qfs1 is this host name.

The following example configuration files show a tested configuration that consists of four SPARC nodes and one AMD x64 node. These nodes are identified as follows:

Sample /etc/hosts File for All Nodes

Prepare /etc/hosts file on all nodes to append settings to existing /etc/hosts table.

Sample Configuration Files for Metadata Server

/etc/nsswitch.conf File

Ensure that the /etc/nsswitch.conf includes cluster. For example:

hosts: cluster files dns nis

/etc/netmasks File

Add the subnet used in your /etc/hosts file to the /etc/netmasks file. For example:

192.168.4.0 255.255.255.0

/etc/hostname.qfe1 File

Identify the NIC port for qfe1 in the /etc/hostname.qfe1 file. For example:

ctelab30-4 netmask + broadcast + group qfs_ipmp1 up addif 
ctelab30-qfe1-test deprecated -failover netmask + broadcast + up

/etc/hostname.qfe2 File

Identify the NIC port for qfe2 in the /etc/hostname.qfe2 file. For example:

ctelab30-qfe2-test netmask + broadcast + deprecated group 
qfs_ipmp1 -failover standby up

Client Network Configuration

In this example, both SPARC and AMD-64 clients are used. SPARC clients run the Oracle Solaris OS and AMD-64 clients use the Linux OS.

SPARC Oracle Solaris Client Network Configuration

• qfe0 used for Public network (129.152.4.0)

• qfe1 used for Sun QFS private network. (192.168.4.0)

AMD-64 RedHat Linux Client Network Configuration

• bge0 used for Public network (129.152.4.0)

• bge1 used for Sun QFS private network. (192.168.4.0)

  ---

  Note - On the Linux OS, the NIC ports identified above are hardware address IDs and the OS identifies these as eth0,eth1 at the OS layer.

  ---

/etc/nsswitch.conf File (SPARC and Linux Clients)

For the clients, make sure that cluster is not listed in the /etc/nsswitch.conf file. For example:

hosts: files dns nis

/etc/hostname.qfe1 File (SPARC Clients Only)

This file should contain the following:

ctelab32-4

/etc/sysconfig/network-scripts/ifcfg-eth1 File (Linux Clients Only)

This file should contain the following:

DEVICE=eth1
BOOTPROTO=static
IPADDR=192.168.4.18
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
