HP DISK SETUPS

To see what disks are currently used by the disk groups

	#strings /etc/lvmconf/*.conf | grep dev
	#vgdisplay -v | more

	#/bin/insf -eH 0/1/1/0.1.0

Disks must be physically setup for volume control
!!**** will initialize disk  DESTROYING  all data on disk

	#pvcreate -fB /dev/rdsk/c#t#d#

Create volgoups first (catvg)

	#mkdir /dev/catvg
	
	Assume only vg00 exists, to verfiy do a
	{
		#ll /dev/*vg*/group
		Note the output, 00 and 01 are used, use 02 now 
		crw-r--r-- 1 root root 64 0x000000 May 23 1997 /dev/vg00/group
		                            ^^	
		crw-r--r-- 1 root sys  64 0x010000 Jun 13 1997 /dev/somevg/group
		                            ^^	
	}
  If only vg00
	#mknod /dev/catvg/group c 64 0x010000

  Else if others, X=largest number + 1 IN HEX (10=a) (but less than 16)
	#mknod /dev/catvg/group c 64 0x0X0000

  Endif

	#vgcreate /dev/catvg /dev/dsk/c#t#d# [disks...]

Create logical volumes

	#lvcreate -n u01lv /dev/catvg

Add the physical disks to the logical volume

	#lvextend -L 800 /dev/catvg/u01lv /dev/dsk/c0t0d0 [disks...]
	             ^size in MB          ^disk dev to add to lv u01lv

Create the file systems
	
	#newfs -F hfs /dev/catvg/ru01lv
		#newfs -F vxfs /dev/catvg/ru01lv
	#mkdir /u01
	#mount /dev/catvg/u01lv /u01
	#vi /etc/fstab

	Insert the following (o)
		/dev/catvg/u01lv /u01 hfs rw,suid 0 2

Mirror the data drives

	#lvextend -m 1 /dev/catvg/u01lv /dev/dsk/c0t0d0
	                               ^phys disk to add to lv u01lv

	#for LV in 1 2 3 4 5 6 7 8 
	#do
	#	echo $LV
	#	ech $LV
	#done
	

To take a copy out of mirror (not normally done)

	#lvreduce -m 0 /dev/catvg/u01lv /dev/dsk/c0t1d0

To view actions

	#strings /etc/lvmconf/*.conf | grep dev
	#vgdisplay [-v] 
	#lvdisplay [-v] /dev/vg00/lvol1
	#pvdisplay [-v] /dev/dsk/c2t5d0

**************************************************************
MIRROR vg00 ON HP/UX:

Make the second disk a boot partition

	#pvcreate -B /dev/rdisk/c#t#d#

Extend the disk into vg00

	#vgextend /dev/vg00 /dev/dsk/c#t#d#

Make the boot partition bootable

	#mkboot /dev/rdisk/c#t#d#
	#mkboot -a "hpux(10/0.5.0;0)/stand/vmunix" /dev/rdisk/c#t#d#
	
Mirror the vg00
	
	#lvextend -m 1 /dev/vg00/lvol# /dev/rdisk/c#t#d#
	             ^one            ^root        ^disk

	#
	# lvol1 (swap) MUST be the first one mirrored - or you will
	#  not be able to boot from mirror
	#
	#for LV in 1 2 3 4 5 6 7 8
	#do
	#	echo $LV
	#	lvextend -m 1 /dev/vg00/lvol${LV} /dev/dsk/c2t1d0
	#done
	# 
	# if you have an extra swap vol (or other non-std vols) 
	# 
	#lvextend -m 1 /dev/vg00/lvolswap  /dev/dsk/c2t1d0

Allow the system to boot from either disk

	#lvlnboot -r lvol1 /dev/vg00
	#lvlnboot -r lvol2 /dev/vg00
	#lvlnboot -v 
	#lvlnboot -v [-d /dev/vg00/lvol2]
	#lvlnboot -R

	#setboot
