Creating volume groups on a virtual disk using vgcreate

You can create a volume group on a virtual disk by issuing a vgcreate command. This builds
the virtual group block data, allowing HP-UX to access the virtual disk. See the pvcreate,
vgcreate,

and lvcreate man pages for more information about creating disks and file systems.

Use the following procedure to create a volume group on a virtual disk:

NOTE:

Italicized text is for example only.

1.

To create the physical volume on a virtual disk, enter the following command:

# pvcreate -f /dev/rdsk/c32t0d1

2.

To create the volume group directory for a virtual disk, enter the command:

# mkdir /dev/vg01

3.

To create the volume group node for a virtual disk, enter the command:

# mknod /dev/vg01/group c 64 0x010000

The designation 64 is the major number that equates to the 64-bit mode. The 0x01 is the
minor number in hex, which must be unique for each volume group.

4.

To create the volume group for a virtual disk, enter the command:

# vgcreate –f /dev/vg01 /dev/dsk/c32t0d1

5.

To create the logical volume for a virtual disk, enter the command:

# lvcreate -L1000 /dev/vg01/lvol1

In this example, a 1-Gb logical volume (lvol1) is created.

6.

Create a file system for the new logical volume by creating a file system directory name and
inserting a mount tab entry into /etc/fstab.

7.

Run the command mkfs on the new logical volume. The new file system is ready to mount.
