Can anyone clarify about LABEL file.

Manu,

Simple version is that the 'lvlnboot' command writes the LABEL file whenever the Boot Data Reserved Area (BDRA) in a bootable Volue Group is modified...

Essentially, the LABEL contains the information that 'lvlnboot' displays/modifies, which is the information that the system uses to determine where the various boot/root logical volumes are located on the boot disk...

HTH...

Manu,

Boot Disk may contain many LVs, which is holding ROOT, BOOT, SWAP and DUMP.

When a system boots hpux refers LABEL file to find the appropriate LVOL.

This LABEL file is updated using lvlnboot and lvrmboot commands.

Update Sequence is

lvlnboot -b bootlvol
lvlnboot -r rootlvol
lvlnboot -s swaplvol
lvlnboot -d dumplvol
lvlnboot -R /dev/vgroot
lvlnboot -v /dev/vgroot

regards,

Senthil
