BOOT LOGICAL VOLUME (BLV) / PROCESSORS / KERNEL


Mirroring does not work with the BLV as it is not a true logical volume,
bosboot must be run against the other disk after mirroring the rootvg.

bootlist -m (normal or service) -o                       displays bootlist
bootlist -m (normal or service) (list of devices)        change bootlist

bootinfo -b                  Identifies the bootable disk
bootinfo -t                  Specifies type of boot 

bosboot -a -d (/dev/pv)      Creates a complete boot image on a physical volume.

mkboot -c -d (/dev/pv)       Zero's out the boot records on the physical volume.

savebase -d (/dev/pv)        Saves customised ODM info onto the boot device.

lslv -m hd5                  Find out which disk the BLV is on.

bootinfo -y                  Displays which kernel can be used, 32 or 64 bit

genkex                       Reports all loaded kernel extensions.

lsdev -Cc processor          Lists all processors
lsattr -EHl proc0            Displays attributes of processor 0. AIX 5.1L will
                             display processor clock frequency.
