Before you can install Solaris 7 on a domain, you need to update the OBP on the SSP by performing the following steps:
Insert the Sun Computer Systems Supplement CD into the CD-ROM drive.
After inserting the CD, wait about one minute for the Volume Manager to mount the CD-ROM.
Log in to the SSP as superuser if you skipped the previous section.
ssp# cd /cdrom/cdrom0/Patches/105684-04
ssp# ./installpatch .
ssp# cd / ssp# eject cdrom
