Configuring filer startup

Startup commands are stored in /etc/rc file

The /etc/rc file contains commands that the filer executes at boot time to configure the filer.

What startup commands do

Startup commands are placed into the /etc/rc file automatically after you run the setup command or the Setup Wizard.

Commands in the /etc/rc file configure the filer to do the following actions:

Communicate on your network
Use the NIS and DNS services
Set the filer's time zone
Save the core dump that might exist if the filer crashed before it was booted
Export directories to NFS, if NFS is licensed and configured
Enable NFS, if NFS is licensed

Default /etc/rc file contents

To understand the commands used in the /etc/rc file on the root volume, examine the following sample /etc/rc file, which contains default startup commands:

#Auto-generated /etc/rc Tue May 30 14:51:36 PST 2000

hostname toaster

ifconfig e0 `hostname`-0

ifconfig e1 `hostname`-1

ifconfig f0 `hostname`-f0

ifconfig a5 `hostname`-a5

route add default MyRouterBox

routed on

timezone US/Pacific

savecore

exportfs -a

nfs on

Explanation of default /etc/rc contents

This section explains the sample /etc/rc file:

Description

hostname toaster

Sets the filer host name to "toaster."

Description



ifconfig e0 `hostname`-0

ifconfig e1 `hostname`-1

ifconfig f0 `hostname`-f0

ifconfig a5 `hostname`-a5

Sets the IP address for the filer network interfaces with a default network mask.

The arguments in single backquotes expand to "toaster" if you specify "toaster" as the host name during setup. The actual IP addresses are obtained from the /etc/hosts file on the filer root volume. If you prefer to have the actual IP addresses in the /etc/rc file, you can enter IP addresses directly in /etc/rc on the root volume. For more information about the ifconfig command, see the Network Management Guide.

Description:

route add default MyRouterBox

Specifies the default router. You can add route commands to /etc/rc on the root volume to set static routes for the filer. The network address for MyRouterBox must be in /etc/hosts on the root volume.

Description

routed on

Starts the routing daemon. For more information about routing, see the Network Management Guide.

Description

timezone US/Pacific

Sets the time zone. The argument to the timezone command specifies which file in the /etc/zoneinfo directory on the root volume describes the time zone you want.

Description

savecore

Saves the core file from a system panic, if any, in the /etc/crash directory on the root volume. Core files are created only during the first boot after a system panic.

Description

exportfs -a

Exports all directories specified in the /etc/exports file on the root volume. This command is included only if the filer runs NFS.

Description

nfs on

Turns on NFS file service. By default, this command is included even if NFS is not licensed for your filer. When the filer runs this command from the /etc/rc file on the root volume on a filer without an NFS license, the command fails and the following messages appear:

NFS service is not licensed.

(Use the "license" command to license it.)

NFS server is NOT running.
