In HPUX the default disk manager is LVM. So steps as per LVM would be:
1) #vgdisplay VOLGRPNAME
for e.g. vgdisplay /dev/vg01
This should be done to check whether u have enough extents free to create a file system of the required size. Also just make sure the the Physical volumes or Hard disks are mirrored or not. Bcos If mirrored then the Free PEs available should be divided by 2 for 2 no. of hard disks.

2) #lvcreate -L SizeM (-n lvname) /dev/vg01
-n is optional u can give any name u like or the filesystem name being created. for .e.g lvcreate -L 100M -n mytmp /dev/vg01
This will create LV of size 100MB /dev/vg01/mytmp and /dev/vg01/rmytmp or else without -n would create /dev/vg01/lvol6 and /dev/vg01/rlvol6, if lvol5 already exists.

3) Now time to create FIlesystem.
Remember the default File system is mentioned on most UNIX systems and so on HPUX system in /etc/default/fs. The default mentioned is VXFS if u have BASE JFS product atleast installed or else will be HFS.
#newfs /dev/vg01/rmytmp
The above will create a new VXFS filesystem with NOLARGEFILES and NOQUOTA arrangement. If u want to enable them then u will need to modify the cmd line like
#newfs -o largefiles,quota /dev/vg01/rmytmp
This is appropriate for files being created above 2GB in size and u can put quota system for users too.
NOTE: the lv name should be starting with 'r' like 'rmytmp'.
4) To make the filesystem available after reboot make the entry in /etc/fstab file.

MKFS.BTRFS(8)						      System Manager's Manual						     MKFS.BTRFS(8)

NAME

       mkfs.btrfs - create an btrfs filesystem

SYNOPSIS

       mkfs.btrfs [ -A alloc-start ] [ -b byte-count ] [  -d data-profile ] [  -l leafsize ] [	-L label ] [  -m metadata profile ] [  -n nodesize
       ] [  -s sectorsize ] [  -h ] [  -V ]  device [  device ... ]

DESCRIPTION

       mkfs.btrfs is used to create an btrfs filesystem (usually in a disk partition, or an array of disk partitions).	device is the special file
       corresponding  to  the  device  (e.g  /dev/sdXX	).   If  multiple   devices  are specified, btrfs is created spanning across the specified
       devices.

OPTIONS

       -A, --alloc-start offset
	      Specify the offset from the start of the device to start the btrfs filesystem. The default value	is  zero,  or  the  start  of  the
	      device.

       -b, --byte-count size
	      Specify the size of the resultant filesystem. If this option is not used, mkfs.btrfs uses all the available storage for the filesys-
	      tem.

       -d, --data type
	      Specify how the data must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.

       -l, --leafsize size
	      Specify the leaf size, the least data item in which btrfs stores data. The default value is the page size.

       -L, --label name
	      Specify a label for the filesystem.

       -m, --metadata profile
	      Specify how metadata must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.

       -n, --nodesize size
	      Specify the nodesize. By default the value is set to the pagesize.

       -s, --sectorsize size
	      Specify the sectorsize, the minimum block allocation.

       -V, --version
	      Print the mkfs.btrfs version and exit.

AVAILABILITY

       mkfs.btrfs is part of btrfs-progs. Btrfs is currently under heavy development, and not suitable for any uses other  than  benchmarking  and
       review.	Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for further details.
