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. HP-UX 53

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.
