Sun Advanced Lights Out Manager system controller (ALOM SC) - only for SPARC system

ALOM System Controller enables you to remotely manage and administer a server.

It comes preinstalled on the machine, so as soon you plug in power cable, it works.

Yes, it uses server's standby power, which enables you to remotely power off and on server (very useful when someone schedule power outage in remote office and you want gracefully to bring server down and after outage power it on).

ALOM monitors hardware in the server, like CPU, RAM, Power supply, etc, and much more like Voltage and status of alarms.

Of course, all this exercise assumes you configured ALOM's network parameters. Try to have dedicated management subnet for this.

If you access ALOM and stay idle for 1 minute, it will switch to serial console.

Or you can type console and reach serial console of remote system from your cube or home living room.

sc> console

To go back to ALOM type #. (pound and dot)

This can be changed (if you really want) from ALOM with

sc> setsc sc_escapechars ## (for example)

hostname console login:

#. ---> switch from console to ALOM

Cannot login to the ALOM?

Try default password which is the last 8 digits of the chassis serial number. Username is admin.

Okay, I don.t want to write much about this, since commands are intuitive and easy to understand (note: they may vary from different ALOM versions)

So find about them by yourself and see what help offers you.

Prefer working from the OS?

For some platforms, like SunFire V240 and V440, ALOM can be configured from OS level using scadm utility.

Unfortunately this is not supported on SunFire T2000.

Examples:

/usr/platform/SUNW,Sun-Fire-V240/sbin/scadm set if_network true

Enable Ethernet link integrity test:

/usr/platform/SUNW,Sun-Fire-V240/sbin/scadm set netsc_tpelinktest true

Enable backup of local user database (username, passwords, permissions) on system configuration card.

/usr/platform/SUNW,Sun-Fire-V240/sbin/scadm set sc_backupuserdata true

/usr/platform/SUNW,Sun-Fire-V240/sbin/scadm set netsc_dhcp false

/usr/platform/SUNW,Sun-Fire-V240/sbin/scadm set netsc_ipaddr 192.168.etc.etc

/usr/platform/SUNW,Sun-Fire-V240/sbin/scadm set netsc_ipnetmask 255.255.255.etc

/usr/platform/SUNW,Sun-Fire-V240/sbin/scadm set netsc_ipgateway 192.168.etc.etc
