I want to know how to do a system recovery for /,/usr and swap running on Logical Volumes for Compaq Tru64 Unix. I will be upgrading the Unix software from 4.0F --> 4.0G --> 5.1, so if had to recover the / and /usr, how do I recover the system. thanks in advance.

The best way (If it's not a cluster) would be to make a bootable tape from sysman --> storage --> create bootable tape.
Because I'm running server 5 way clusters I can't do that. So I would just reinstall the OS then recreate the domains and filesystems.
To recreate a domain use
mkfdmn /dev/diskname domainname
Next add disks to the domain
addvol /dev/diskname domainname
repeat for each disk you wish to add to the domain
Make the FILESETS in the DOMAIN
mkfset domainname live
mkfset domainname users
mkfset domainname test
Make the DIRECTORIES
mkdir /live
mkdir /users
mkdir /test
Mount the FILESETS
mount –t advfs domainname#live /live
mount –t advfs domainname#users /users
mount –t advfs domainname#test /test
Define the FILESET sizes
chfsets -b 204800 domainname /live
chfsets -b 204800 domainname /users
chfsets -b 8192000 domainname /test
Restore the FILESETS
cd /live; vrestore –xvf
cd /users; vrestore –xvf
cd /test; vrestore –xvf
Depending on the number if disks used (E.g. 2 or more) balance the FILE DOMAIN
balance data
Take a look at the vrestore man page for more details on vrestore
man vrestore
Regards Mike
