Tru64 Unix Installation

[Ahmed Saleem]

Hi All,
There is an Alpha Server i.e. DS 20. The system HDD is of 18GB and we want to replace this disk to 36GB and we have installed the new disk of 36Gb and want to install the OS of same configuration that is installed in 18GB HDD. So what are the different ways to install the OS with the same configuration and also want to create the same mount points on new HDD. Can we dump that drive or cp the root filesystem to 36Gb HDD.
Thanks, waiting for the quick reply

Dear Ahmad,

you have to vdump your system with
vdump -u0Nf /dev/ntape/tape0 /
vdump -u0Nf /dev/ntape/tape0 /usr
vdump -u0f /dev/ntape/tape0 /var

Install the new HD

Then boot from OS CD choose shell windows
# dn_setup -install_tape ( This to install tape driver)
then locate the name of new disk
# disklabel -z dsk?
# disklabel -rw -t advfs dsk?
# diskconfig ( GUI Utility to partition your disk )
a root
b swap
g usr
h var ( make sure if usr and var on same domain or diff. domain )

# mkfdmn /dev/disk/dsk?a root_domain
# mkfset root_domain root
# mount root_domain#root /mnt
# cd /mnt
vrestore -xvf /dev/ntape/tape0
make same thing for usr and var

when u reboot first boot to singlt user mode
using boot -fl 0 ( from new 36G Disk
# bcheckrc ( check and mount FS )
try to make the new disk name same as old one
# hwmgr -show scsi
(locate null disk )
# hwmgr -delete comp -id ??? (the null disk)
rename new disk to the old disk
# dsfmgr -m newdiskname olddiskname
ex: # dsfmgr -m dsk5 dsk0
# bchckrc

every thing should work fine

Regards
Nabil

Hi Nabil,
All the FS are on 4.3BSD not on AdvFs. So can u forward me the whole procedure for this activity. For this we must dump the whole disk or FS to tape. Can we dump the root and other FS from drive to drive ...
Thanks ..

Hi All,
me waiting ... kindly, reply ASAP. All FS are running on 4.3BSD on old HD NOT ON AdvFS. So kindly forward the whole procedure so that i will be able to do this activity. How can i transfer my all OS configurations from the old HD to newone.

In that case replace
"vdump -u0Nf /dev/ntape/tape0 /
vdump -u0Nf /dev/ntape/tape0 /usr
vdump -u0f /dev/ntape/tape0 /var"
with
dump -u0Nf /dev/ntape/tape0 /
dump -u0Nf /dev/ntape/tape0 /usr
dump -u0f /dev/ntape/tape0 /var
(must dump all file systems on that disk)
and replace:
"# mkfdmn /dev/disk/dsk?a root_domain
# mkfset root_domain root
# mount root_domain#root /mnt
# cd /mnt
vrestore -xvf /dev/ntape/tape0"
with:
# newfs /dev/disk/dsk?a
# mount /dev/disk/dsk?a /mnt
# cd /mnt
# restore -xvf /dev/tape/tape0
