HP XP10000, XP128 manual # mknod /dev/vg06/group c 64

Page 41

Example

In this example: group name = vg06, major number of group file = 64,

 

minor number of existing group file = 06 (which must be unique for

 

each volume group), and c = character.

#mknod /dev/vg06/group c 64 0x060000

:

7.Create the volume group.

To allocate more than one physical volume to the new volume group, add the other physical volumes, separated by a space.

Example # vgcreate /dev/vg06 /dev/dsk/c6t0d0

Volume group "/dev/vg06" has been successfully created.

Volume group configuration for /dev/vg06 has been saved in /etc/1vmconf/vg06.conf.

For Logical Unit Size Expansion (LUSE) volumes that contain more than 17 OPEN-8/9 LDEVs or more than 7043 MB (OPEN-8/9*n-CVS), use the –sand –ephysical extent (PE) parameters of the vgcreate command. See “LUSE device parameters” (page 68).

If you need to delete a volume group, use the vgremove command (for example, vgremove /dev/vgnn). If the vgremove command does not work because the volume group is not active, use the vgexport command (for example, vgexport /dev/vgnn).

8.Use the vgdisplay command to verify that the new directory was created.

9.Use vgdisplay –vto verify that the volume group was created correctly. The –voption displays the detailed volume group information.
