Hello,
Many thanks for all the replies. I found that
one of memory chip was also creating problems.
So I checked the memory(done memory test) and removed the defect one.
Afterwards I did the following and every thing
works now. Once again thanks for all the valuable
replies.
Boot from CD
Executed the following UNIX commands:
cd /dev
./MAKEDEV rz24
disklabel -wr -t advfs rz24 rzxx (made it bootable
and rzxx means disklabel recoganises the disk type)
made the new partitions size on the disk
made the domains(Ex: mkfdmn /dev/rz24 root2_domain)
mounted the domain partitions
restored the files from tape
Now everything works.
Many thanks for all the help.
Regards,
Kumar
The First Question was:
=======================
I had a disk problem on a Tru64 machine with OS 4.0F
So I removed the disk from the machine and put in a
Tru64 machine with OS V5.1A. I also put a new disk
(same type) on V5.1A machine. Both disks are 9GB.
Wrote the label on the
new machine and made a back up from the defect disk
on the new disk.
Removed the new disk and put in the OS 4.0F machine
and tried to boot with out success. System complained
because of difference in AdvFS versions.
Now I tried to relabel the
the new disk on Tru64 with OS 4.0F with the command
disklabel -w -r rz26 after booting the system from 4.0F CD.
Wrote the command mount -u /.
Created device rz26 with /dev/MAKEDEV rz26.
I could label the disk and partition the disk with
disklabel -e rz26. But I cannot create advfs on this disk.
When I write mkfdmn /dev/rz26a root2_domain I get the
following error:
/dev/rrz26a is an invalid device or cannot be opened.
The disklabel for /dev/rrz26a cannot be updated.
Quitting .....
mkfdmn: can not make new domain "root2_domain"
Is there a label information on the disk from OS v5.1A?
How can I label and create domain on this disk? I need it
urgently? Please help.The disk type is BD009222C7.
Regards,
Kumar
The second Question was:
=======================
I got few answers. I did the following as suggested
by few of you.
1. Removed the disk from 4.0F OS machine and connected
on the OS 5.1A machine.
2. Executed the command zero: /usr/lbin/zeero /usr/rdisk/dsk3c
3. Removed the disk and connected on the 4.0F machine.
4. Booted the 4.0F machine from 4.0F CD
5. Changed to UNIX shell modus.
6. Executed the command: mount -u /
7. Executed the command: disklabel -z rz24c
(The disk type is BD009222C7)
8. /dev/MAKEDEV rz24
9. disklabel -wr rz24
10. mkfdmn /dev/rz24a root2_domain
Then I get the error:
/dev/rrz24a is an invalid device or cannot be opened.
The disklabel for /dev/rrz24a cannot be updated.
Quitting .....
mkfdmn: can not make new domain "root2_domain"
11. Also tried newfs /dev/rz24g
I got the error:
/dev/rrz24a is an invalid device or cannot be opened.
The disklabel for /dev/rrz24a cannot be updated.
What Iam doing wrong? Is there any parameter missing
in disklabel command?
