Why is this soo cool? Because the default way to upgrade the OBP is to have a running system. But some times

If you have a working jump start enviroment most of the work is already done, yaha. You actully dont even have to use a solaris box to act as the upgrade server any tftp server will do.

So basically what I did here is used a already set up jump start server to upgrade the OBP on a Sun Fire v240. I deleted the link to the solaris kernel and created a symlink from the mac address to the upgrade binary.

bash-3.00# pwd
/tftpboot
bash-3.00# ls -l
total 458
lrwxrwxrwx 1 root root 27 Jun 6 11:40 0A2483F9 -> inetboot.SUN4U.Solaris_10-1
lrwxrwxrwx 1 root root 27 Jun 6 11:40 0A2483F9.SUN4U -> inetboot.SUN4U.Solaris_10-1
-rwxr-xr-x 1 root root 217016 Jun 6 11:40 inetboot.SUN4U.Solaris_10-1

-rw-r–r– 1 root root 321 Jun 6 11:40 rm.10.36.131.249
lrwxrwxrwx 1 root root 1 Jun 5 10:23 tftpboot -> .

bash-3.00# ls -l ODBUpgrade/

Deleting file that have special characters in them can be tricky. This is what you have to do to delete them.

because rm -r -file will give you a error
[root@solaris:/]# rm -C

rm: illegal option — C
usage: rm [-fiRr] file …

so what you have to do is search figure out what the inode is

[root@solaris:/]# ls -il -C
total 2723130
32081 -rw-r–r– 1 root root 1392916480 Dec 4 14:55 -C

the 32081 is the inode number

[root@solaris:/u10/app 102]# find . -inum 32081 -exec rm -i {} \;
rm: remove ./-C (yes/no)? y

now the file is gone, yaha!

When trying to remove package SMCsudo you get the error

#pkgrm SMCsudo

The following package is currently installed:
SMCsudo sudo
(sparc) 1.6.8p4

Do you want to remove this package? y

do

# cd /var/sadm/pkg

which is where the package database is located

then delete the offending package that you are trying to remove.

rm -rf SMCsudo

Then the package is removed the ugly (hack) way.

So then you can now install thenewer version of the same package.

# pkgadd -d /tmp/SMCsudo
