Setup Procedure for the ALOM Network Management InterfaceBernhard Hallerbach, July 2006 About the Advanced Lights Out Manager (ALOM)ALOM is a system controller providing a command-line interface that can be used to remotely monitor and control Sun Fire V series servers. ALOM enables the administrator to run diagnostics (such as POST) remotely and can be configured to send email alerts of hardware failures/warnings or other server-related events. Components that ALOM can monitor include, for example, system temperature and voltages, CPUs, disk drives, fans, and power supplies. ALOM runs independently of the server, using the server's standby power. Therefore, its firmware continues to function when the server operating system goes offline or when the server is powered off. Setup Procedure for the ALOM Network Management InterfaceNote: I've tested the instructions with ALOM versions 1.3, 1.5.1 and 1.5.4. Some configurable options of version 1.5.x are missing in earlier versions, but this does not affect the given instructions. 1. Collect the required setup data for the network management interface as shown here.
2. Establish a serial connection to the port named prompt% tip /dev/term/a -9600 connected
Enter the escape sequence
3. First set a login password for the default user sc> password password: Changing password for admin Enter new password: ******** Re-enter new password: ******** sc> 4. Set up the network management interface: sc> setupsc Entering Interactive setup mode. To exit and discard changes to that point, use Ctrl-C or to exit and save changes to that point, use Ctrl-Z.

The available options are 'none', 'xir' or 'reset' where an xir will attempt to collect diagnosis data before invoking a reset [xir]? xir How many seconds should be allowed for an XIR to complete (maximum timeout of 10800s) [900]? 900 Do you wish to configure the network management interfaces [y]? y Enter the number of mail servers to configure [0]? 1 Enter the IP address for mail server 1 [100.100.100.100]? <mailhost-ip> Enter the number of email recipients to configure [0]? 1 Enter the email address for recipient 1 (maximum of 30 characters) []? <email@address> Enter the level of events to send to recipient 1 where valid settings are 1 (critical), 2 (critical and major) and 3 (critical, major and minor) [2]? 2 Do you wish to configure the SC parameters [y]? y Enter any customer data for this platform (maximum of 40 characters) []? <some-customer-data> Enter the console session escape sequence (2 characters). The first character can be any printable characters or control-A through control-Y except for control-C, control-D, control-H, control-J, or control-M. The second character must be a ".". [#.]? #. Enter level of events to be displayed over the CLI where valid settings are 0 (none), 1 (critical), 2 (critical and major) and 3 (critical, major and minor) [2]? 2 Should poweron sequencing be enabled [y]? y Enter the SC cli prompt (maximum of 16 characters) [sc]? <sc-cli-prompt> Enter the SC CLI timeout in seconds (maximum of 10000s) [0]? 0 Should password entry echo '*'s [y]? y Your ALOM configuration profile has been successfully completed.
