Hi,

the easiest way is to install TRU64 onto it or can you specify if you need something else?

greetings,

Michael

Hi mmain:

There are a few things:

1- Carefully read the system administration manual available at the tru64 documentation page. Page 9-36 gives detailed information about how to run the btcreate utility.

2- You should boot with the following options:

boot -fl "nc" tape_device

3- I never used a btcreate tape to restore a system, a good backup with vdump allows me to restore the system without booting from the tape. I boot from the installation CD, run command shell, recreate the filesytems with mkfdmn [-r] and mkfset, and restore the backup. The system boots smoothly.
