Once the tape drive is inthe boot list simply insert the mksysb tape into the drive and power on - the tape has a boot image and will restore the rootvg automatically. There are a few screens to answer, but they are pretty intuitive and straigtforward.

I hope this helps.

Thanks a lot for your help

For recovery I have this same tape device (type and model) and faster/more powerfull RS6000. I want to save time and try to load the system from mksysb backup I hope that's will be possible, I don't know exac configuration yet.

tcopy

tcopy(1)							   User Commands							  tcopy(1)

NAME

       tcopy - copy a magnetic tape

SYNOPSIS

       tcopy source [destination]

DESCRIPTION

       The  tcopy  utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
       contents of a tape is that there are two tape marks at the end.

       When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a  des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces the same output as it does when only scanning a tape.

       The tcopy utility requires the use of Berkeley-compatible device names. For example,

	 example% tcopy /dev/rmt/1b /dev/rmt/2b
