Unix/Linux 中的 如何克隆HP-UX系统盘

可以分两个阶段来做;
第一阶段
1 pvcreate -B /dev/rdsk/cxtydz
2 mkboot /dev/rdsk/cxtydz
3 mkboot -a "hpux -lq(；0）/stand/vmunix" /dev/rdsk/cxtydz
第二阶段
1 dd if=/dev/dsk/c1t2d0 of=/dev/dsk/cxtydz
bs=1024k
供参考：
If you do not have Mirror/UX you can manually duplicate your boot disk to another disk. This is the process.
* Assuming current LVM boot disk is on c1t2d0 and you want to duplicate to c2t2d0.
# pvcreate -B /dev/rdsk/c2t2d0
# mkdir /dev/vgroot; mknod /dev/vgroot/group c 64 0x010000
# vgcreate /dev/vgroot /dev/dsk/c2t2d0
# mkboot /dev/rdsk/c2t2d0
# mkboot -a "hpux (;0)/stand/vmunix" /dev/rdsk/c2t2d0
# lifls /dev/rdsk/c2t2d0
==> do lifcp of all other boot utilities from c1t2d0 to c2t2d0.
# lvcreate -C y -r n -n lvol1 /dev/vgroot
# lvextend -L 84 /dev/vgroot/lvol1 /dev/dsk/c2t2d0
==> creating and extending boot lv (/stand)
# lvcreate -C y -r n -L 2048 -n lvol2 /dev/vgroot
==> creating swap LV
# lvcreate -C y -r n -n lvol3 /dev/vgroot
# lvextend -L 6544 /dev/vgroot/lvol3 /dev/dsk/c2t2d0
==> creating and extending root lv (/)
# lvlnboot -b lvol1 /dev/vgroot
# lvlnboot -r lvol3 /dev/vgroot
# lvlnboot -s lvol2 /dev/vgroot
# lvlnboot -d lvol2 /dev/vgroot
==> update BDRA for boot, root, swap and dump LVs.
# newfs -F hfs /dev/vgroot/rlvol1 ==> /stand must be hfs
# newfs -F vxfs /dev/vgroot/rlvol3
# mkdir /newstand
# mount /dev/vgroot/lvol1 /newstand
# cd /stand
# find . -xdev -depth -print|cpio pxdm /newstand
# umount /newstand
# mkdir /newroot
# mount /dev/vgroot/lvol3 /newroot
# cd /
# find . -xdev -depth -print|cpio -pxdm /newroot
# cd /newroot/etc
# vi fstab
==> edit appropriately
# lvlnboot -R
==> resync vg headers
# setboot -p 0/0/2/0.2.0
==> change prim boot path to new disk (c2t2d0)
The above assume you have /, /stand and swap only. If you have separate /opt, /usr, /tmp mounted for example, perform appropriate lvcreate on those. When it's all done you should be able to boot up from your 2nd disk. From here onwards, you have to manually synchronize bot your boot disks.
