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
