C H A P T E R 2 - Customizing the Configuration

This chapter describes the use of the netcfg command when configuring system parameters. It contains the following sections:

Setting Network Configuration Parameters

You use the netcfg command to set various network configuration parameters, including:

The subsections that follow explain how to set these network configuration parameters.

Configuring an SMTP Server

Type netcfg smtp followed by an IP address and port number to set the location of the SMTP server.

hc $ netcfg smtp 10.7.224.15 25

Configuring a Gateway

Type netcfg gw followed by an IP address and subnet mask to set the default gateway (router) that the Sun StorageTek 5800 system uses.

hc $ netcfg gw 10.7.227.254 255.255.255.0

Configuring External NTP Servers

Type netcfg ntp followed by the IP addresses to configure the external NTP servers that the Sun StorageTek 5800 system uses.

hc $ netcfg ntp 10.7.224.30,10.7.224.40

It is required that you specify external NTP servers. The Sun StorageTek 5800 system requires a time server be configured.

Configuring an External Log Host

Type netcfg loghost followed by an IP address to set an external log host for the Sun StorageTek 5800 system.

hc $ netcfg loghost 10.7.224.15

Configuring Authorized Clients

1. Enter netcfg clients followed by the IP addresses to configure authorized clients.

hc $ netcfg clients 10.45.1.19,192.18.7.2,34.7.7.101

Note that specifying authorized clients is optional. If you do not set this property, data access to the system is granted to any client on the network.

2. Enter netcfg clients all to reset this property and allow all clients to enter the system.

hc $ netcfg clients all

Configuring the Alert Subsystem

You use the alertcfg command to configure the alert subsystem. You can set the external log and email alert hosts, as well as any other alert parameters, such as email addresses for email alerts. Should you enter alertcfg with no parameters, the current values will display.

Type alertcfg add to or alertcfg del cc to add or delete an email address from the specified list type.

hc $ alertcfg add to alerts@samplecompany.com

hc $ alertcfg del cc admin@samplecompany.com

Setting External Virtual IP Addresses

Use the ifconfig command to set the external virtual IP addresses. All network and node addresses that are internal to the cluster are private and not configurable. The cluster has two public host addresses, one for the data VIP and one for the administrative VIP.

hc $ ifconfig data0 10.7.224.42

hc $ ifconfig admin0 10.7.224.41
