pvcreate(1M) pvcreate(1M)

Warning: The

-f option should only be used as a last resort to over write ﬁle

system or volume manager information that cannot properly be removed using

the commands designed for that purpose. When invoked with

-f, the com-

mand does minimal veriﬁcation, so care should be taken to assure that the

disk is not already in use prior to invoking the command.

-t disk_type Retrieve conﬁguration information about the physical volume from the ﬁle

/etc/disktab. disk_type speciﬁes the device (for example, hp7959S).

The disk_type only needs to be speciﬁed when

pvcreate fails to get the size

from the underlying disk driver. If the driver successfully returns the size of

the device, disk_type is ignored.

Note

The user data size of the same physical volume may differ, when initialized by

pvcreate command

under different releases of HP-UX.

EXTERNAL INFLUENCES

Environment Variables

LANG determines the language in which messages are displayed.

LANG is not speciﬁed or is null, it defaults to "C" (see lang (5)).

If any internationalization variable contains an invalid setting, all internationalization variables default

to "C" (see environ (5)).

EXAMPLES

Create a physical volume on raw device

/dev/rdsk/c1t0d0

, and force the creation without

conﬁrmation:

pvcreate -f /dev/rdsk/c1t0d0

Create a bootable physical volume for an HP Integrity system on raw device /dev/rdsk/c1t0d0s2

and force the creation without conﬁrmation:

pvcreate -fB /dev/rdsk/c1t0d0s2

WARNINGS

If you are using pvcreate command on an HP Integrity system boot disk, ensure that the speciﬁed dev-

ice special ﬁle correspond to the HP-UX partition. For example,

pvcreate /dev/rdsk/c1t1d0s2

pvcreate initializes only the ﬁrst 2,147,483,647 Kilobytes (2TB - 1KB) of disk space when the disk size

exceeds this value. Disk space beyond this point will not be used by LVM.
