[SUMMARY] mass rollout of flash updates on U5/10s

2007-12-25 11:21:00

Thanks go to Matthew Stier and Thomas Jackson.

Turns out that it is certainly possible to boot the flash-update kernel over

the network. After carefully watching a local update, I got it to work.

The flash-update kernel reads some information from /platform, which means that

you must have a network boot image (like the one in Solaris_x.x/Tools/Boot for

the install server) in order for flash-update to do its magic.

I was trying to boot the flash-update *as* the kernel over the network --

meaning that the file that was TFTP'ed to the client at boot time was the

flash-update file. This failed miserably because it couldn't read the files in

/platform.

The proper way to do it is to set up a network boot image (Tools/Boot), add the

client (run add_install_client), and put the flash-update file in the root dir

of the boot image. (make sure the flash-update is chmod 0755!)

Then you go to the client and do 'boot net /flash-update-file-name'.

The network boot kernel will mount the boot image via NFS, allowing the

flash-update kernel to read /platform and continue on its merry way.
