Error How to restore rootvg archive after AIX 6.1 crash

Hello,
Few days ago I created both mksysb and savevg archives of rootvg.
How can I restore this rootvg now because the AIX crashed during some software tests. There is no way to start from hdisk0 because most of the system files are deleted (this includes libc.a).
I tough it will be trivial task to restore the system from archive, but when I booted from original AIX 6.1 DVD it only accepts restoration from tape or DVD. I have this archives on NFS.
I tried to mount iscsi but the operation failed because of missing command ...
I'm using the original IBM AIX DVD. The machine is IBM P520.
We have VIOS server installed on it.

Thank you in advance for your help.

NAME
aset.restore - restores system files to their content before ASET is installed SYNOPSIS
aset.restore [-d aset_dir] DESCRIPTION
aset.restore restores system files that are affected by the Automated Security Enhancement Tool (ASET) to their pre-ASET content. When ASET is executed for the first time, it saves and archives the original system files in the /usr/aset/archives directory. The aset.restore utility reinstates these files. It also deschedules ASET, if it is currently scheduled for periodic execution. See asetenv(4). If you have made changes to system files after running ASET, these changes are lost when you run aset.restore. If you want to be abso- lutely sure that you keep the existing system state, it is recommended that you back-up your system before using aset.restore. You should use aset.restore, under the following circumstances: You want to remove ASET permanently and restore the original system (if you want to deactivate ASET, you can remove it from schedul- ing). You are unfamiliar with ASET and want to experiment with it. You can use aset.restore to restore the original system state. When some major system functionality is not working properly and you suspect that ASET is causing the problem; you may want to restore the system to see if the problem persists without ASET. aset.restore requires root privileges to execute. OPTIONS
The following options are supported: -d aset_dir Specify the working directory for ASET. By default, this directory is /usr/aset. With this option the archives directory will be located under aset_dir. FILES
/usr/aset/archives archive of system files prior to executing aset ATTRIBUTES
