[SunHELP] SUN NVRAM/hostid FAQ & E450

[sunhelp at sunhelp.org]

It should be, if not you can pop the NVRAM into another system and program it
there. Where I used to work, we used a sparc 10 to program all M49T09 (NVRAM
in the Ultras) and M48T08's (NVRAM in the sun4m systems) and a sparc 2 to
program all M48t02s (NVRAM for the sun4c systems).

Im not sure what the FAQ says but as long as you scramble the checksum it
*should* work.

0 0 mkp
8 0 20 aa bb cc 80aabbcc mkpl
^d^r (control+d followed by control+r)

if you get a message along the lines of (copyright Sun Micro Systems) then try
1 1 mkp instead and repeat the sequence above.

Regards,

Hi,

Did anyone successfully modified the hostid of an E450 with the method
described in "SUN NVRAM/hostid FAQ"  at
http://www.squirrel.com/squirrel/sun-nvram-hostid.faq.html
<http://www.squirrel.com/squirrel/sun-nvram-hostid.faq.html>

I plan to migrate 3 hosts with less downtime as possible, and would like to
use another host (E450) to prepare the job (installing/configuring Solaris,
and many additional software, then copy the working software set to the
target host). As I don't want to deal with various software licences loans
for each installation, I'd like to temporarily put the target host hostid
for each installation.

I just wonder if the FAQ method is valid for an E450, as it is not
explicitly stated in the FAQ.
