Re: Corrupting a LIF area
Hi,
# lifrm /dev/rdsk/cxtydz:F
or something more wild, dd something to the first part of the disk
# dd if=/dev/zero of=/dev/rdsk/cxtydz bs=2k count=2

Re: Corrupting a LIF area
Note that corrupting th LIF area has diffrent meanings..the lifrm command removes commands like hpux (the HP-UX bootstrap program) but using dd to the beginning of the disk area will not only destroy the LIF area but also the BDRA (Boot Data Reserved Area) which contains information about the LIF and boot areas, and also destroy the disks VGRA which has all the details about the logical volumes on this disk. So recovering from the dd command will be much more involved than removing files from the LIF area.
