Rootability indicates that the volumes containing the
root file system and the system swap area are under VxVM control. Without rootability, VxVM is usually started after the operating system kernel has passed control to the initial user mode process at boot time. However, if the volume containing the
root file system is under VxVM control, the kernel starts portions of VxVM before starting the first user mode process.
Under HP-UX, a bootable root disk contains a Logical Interchange Format (LIF) area. The LIF LABEL record in the LIF area contains information about the starting block number, and the length of the volumes that contain the
root file systems and the system swap area. When a VxVM root disk is made bootable, the LIF LABEL record is initialized with volume extent information for the
dump (if present) volumes.
See "Setting up a VxVM root disk and mirror" on page 105.
From the AR0902 release of HP-UX 11i onward, you can choose to configure either a VxVM root disk or an LVM root disk at install time.
