how to remove hard disk partition table in solaris
hello experts
i got a ultra 80 workstation
it had a Redhat8 when i bought. and it was working fine.
know i am trying to install solaris 10 onthe system its giving very funny errors
it has 2 disk raid 1 i beleive. (mirror)
at ok prompt i run the format command and formated disk0 and disk1 and it went perfect
here is the problem
after formating
i ran
ok boot cdrom
went fine untill i selected the region but before installing it gave this error
no disk found
check to make sure disks are cabled and powered up
the disk are ok i can see 2 disks
when i did the format it did format
format -print -print
i can still see disk partition table of redhat8 . i think
i try to delete the partiton 0- 7 i deleted easy . and when it come to 8 its not excepting the command
its labeled as reserved . i think that the issue
to my knowledge slice 2 is take the control in solaris
in the same way slice 8 is by redhat i think . which causing the problem and its not deleting
all i need to deleted the disk partion table of exisitng redhat 8. which didnt deleted after using format command on both disks
please tell me the command to delete the disk partion or any suggestion to overhead this issue
i check the manual sol8 9 10 are compatible on i t
i study the whole handbook of ultra80 workstation cant find the error which i got here
waiting for early reply
please tell what option i can try to delete the existing disk partiton table . (which i think is the issue here but i might be wrong )

The disk most likely still have a RedHat label. Boot from Cd and at format see if you can label them.

thanks jekl2000 i tried that way but didnt work .

this is how it was showing when i try to install the solaris 10. if you see the partition table. its reserverd 8 and didnt let me delete the partion
and when installing half of the way of installation. i was getting the error (no hard disk found. cuase solaris couldnt able to read the linux partition talble

by one of collegue iwas being told that it has EFI label . which dont make sense to me. and we try to change to SMI label and that worked
but it ony took 4 hours to figure that out.
[So that looks like a valid EFI label - let's try again to write the SMI label, now that we have used "luxadm -e forcelip" once.]
