Answer

The Remote LAN Module (RLM) provides remote management capabilities, including console redirection, logging, and power control. It also extends AutoSupport by sending additional system event alerts. Your AutoSupport settings are used for sending these alerts via e-mail over the RLM LAN interface.

What systems have an RLM available to them?

All FAS30x0, FAS31x0, and FAS60x0 series support having an RLM, but may not be installed.

How do I configure an RLM for use?

When setting up a filer for the first time, you will be asked to configure the RLM.

Example:
Would you like to configure the RLM LAN interface [y]:
Would you like to enable DHCP on the RLM LAN interface [n]: n
Please enter the IP address for the RLM [ ]: 10.100.10.11
Please enter the netmask for the RLM [ ]: 255.255.255.0
Please enter the IP address for the RLM gateway [ ]: 10.100.10.1
The mail host is required by your system to send RLM
alerts and local autosupport email.
Please enter the name or IP address of the mail host []: mailserver.company.com


The RLM can be re/configured at any time from within Data ONTAP by running the following command:

7-Mode Example:
filer> rlm setup
Would you like to configure the RLM? y
Would you like to enable DHCP on the RLM LAN interface? n
Please enter the IP address for the RLM [ ]: 10.100.10.11
Please enter the netmask for the RLM [ ]: 255.255.255.0
Please enter the IP address for the RLM gateway [ ]: 10.100.10.1

Cluster-Mode Example:
cluster::> node run -node <node_name>
node_x> rlm setup
Would you like to configure the RLM? y
Would you like to enable DHCP on the RLM LAN interface? n
Please enter the IP address for the RLM [ ]: 10.100.10.11
Please enter the netmask for the RLM [ ]: 255.255.255.0
Please enter the IP address for the RLM gateway [ ]: 10.100.10.

How do I login to the RLM?

Use an SSH capable client to connect to the IP address.  By default, the RLM looks for SSH connections instead of telnet. The login for the RLM is 'naroot' and the password is the password of the root user.  Upon login, you will notice that the filer prompt has an 'RLM' preceding the filer name.
 
7-Mode Example:
login as: naroot
Password:

RLM filer>
 
Note: If a root password is not set on the filer, you will not be prompted for one.
 
Example:
login as: naroot

RLM filer>

Cluster-Mode Example:
Login as: admin
Password:

RLM filer>
