This section describes the physical objects (physical disks
and partitions) used by Volume Manager.
Physical Disks and Disk Naming |
 |
A physical disk is the basic storage
device (media) where the data is ultimately stored. You can access
the data on a physical disk by using a device name (devname)
to locate the disk. The physical disk device name varies with the
computer system you use. Not all parameters are used on all systems.
Typical device names can include: c#t#d#, where:
On an HP-UX 11i Version 1.5 system, the HP-UX partition number
on the boot disk drive is: c#t#d#s2, where:
Partitions |
|
On some computer systems, a physical disk can be divided into
one or more partitions. The partition number, or s#, is added at the end of the device name. Note that
a partition can be an entire physical disk.
For HP-UX 11i, all the disks (except the root disk) are treated
and accessed by the Volume Manager as entire physical disks using
a device name such as c#t#d#. On HP-UX 11i Version 1.5, the root disk is on partition
2, c#t#d#s2.
