Hardware

This machine is a Sun Microsystems Sun Fire v210. It bears serial number FM33910143. This model was end-of-lifed in June of 2006 [1]

Lights Out Management

Sun's, erm, Oracle's, docs on this machine's ALOM can be found at http://docs.oracle.com/cd/E19102-01/n440.srvr/819-2445-11/configure.html (as of this writing, anyway)

ALOM login credentials have not yet been re-set. This should be possible after Solaris is installed using setdefaults -a or something similar.

ALOM login credentials can be re-set (or a new user ALOM user can be added) with software included with Solaris. /usr/platform/$(uname -i)/scadm will be your friend, here. It has a helpful "help" option.

If you feel the urge to update the ALOM firmware, be sure the system firmware requirements are met. I had OpenBoot version 4.8.something and ALOM verison 1.0. Updating to ALOM 1.6 required a more recent OpenBoot. The more recent OpenBoot's requirement for ALOM >= 1.2.x wasn't mentioned until the very end of the OpenBoot update document. The machine seems to have survived, but the unmatched dependencies were a cause of concern for a while.

Setting the ALOM for DHCP is a matter of getting a user with "cuar" permissions, connecting to the ALOM on the serial console or over the network, and running the setupsc' from the ALOM's shell. It will ask a lot of questions. Most can safely be ignored for now. The DHCP enable option is pretty obvious, though. Re-setting the configuration of the ALOM is accomplished by running setdefaults from the ALOM shell.

memory

OpenBoot firmware reports 1024Mibytes of RAM installed. 16Gbytes of RAM is the maximum supported configuration.[2]

Software

network boot

OpenBoot gets zeroth Ethernet NIC's IP address by RARP. Install rarpd and add an entry to /etc/ethers. This machine is at 00:03:ba:45:e8:c1.

After successfully getting its IP address by RARP, it then requests by TFTP a file which is a hexadecimal encoded version of its IP address. The needed file can be found on the Solaris 10 SPARC installation DVD at Solaris_10/Tools/Boot/platform/sun4u/inetboot. Copy this to a file with a meaningful name on your TFTP server and create a symlink that matches the hex-encoded IP address:

install -o root -g root -m 444 /media/cdrom0/Solaris_10/Tools/Boot/platform/sun4u/inetboot /var/local/tftp/inetboot.Solaris10_SPARC_sun4u
ln -s inetboot.Solaris10_SPARC_sun4u /var/local/tftp/AC100021

This machine should be able to get its network boot loader by TFTP now. If problems are encountered, check the following:

• Is there a RARP server running?
• Is the client machine listed in /etc/ethers?
• Is there a TFTP server running on the local subnet? (client system here broadcasts TFTP requests)

Now that the bootloader is running, it needs a bootparam server to talk to. This will tell it where to load the kernel from and where to find its root filesystem. apt-get install bootparamd and put something like the following in /etc/bootparams:

172.16.0.33     root=172.16.0.1:/srv/nfsroot/solaris_install/Solaris_10/Tools/Boot \
                install=172.16.0.1:/srv/nfsroot/solaris_install/Solaris_10 \
                rootopts=:rsize=8192 boottype=:in

And then realize that bootparamd doesn't cope with IP addresses in there. It does a gethostbyaddr for the client's IP address, so /etc/bootparams needs to look like

dhcp-pool-33.fnord.greeley.co.us root=172.16.0.1:/srv/nfsroot/solaris_install/Solaris_10/Tools/Boot \
 install=172.16.0.1:/srv/nfsroot/solaris_install/Solaris_10 \
 rootopts=:rsize=8192 boottype=:in

instead.

After the installer tries every available Ethernet interface, you may encounter a message similar to "bpgetfile unable to access network". I found that the machine with an IP address of 172.16.0.33 thinks that it is on a Class B network. Which makes a sad kind of sense -- there wasn't any DHCP done to figure out the netmask for that network segment.

Be sure to have the NFS mounts listed in bootparams available to the client system. Feel free to use ifconfig to manually adjust the IP configuration, setting netmask and broadcast address. And then exit to continue the installer.
