when I get mksysb made on power5 system and then 'alt_disk_mksysb' it on target power5 system it finshes without any problem and I can boot from the drive where 'alt_rootvg' was created.
when I do the same, with the same mksysbbut on target system which is P6 system alt_disk_mksysb finshes without any problems as well, bootlist is set to the drive pointing to the 'alt_rootvg' but when I reboot system it never starts - hangs on:
