asked on

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.

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.]

#format -e

[0] SMI Label
[1] EFI Label
Specify Label type[1]: 0
Auto configuration via format.dat[no]? n
Auto configuration via generic SCSI-2[no]? y
Ready to label disk, continue? y
format> q
