Operating Systems HP-UX RAID 5 on HP-UX
# 8  
Old 09-11-2009
From my point of vue, I would say no because HP-UX has no software to do so, mirror-ux will do mirroring, RAID5 is achieved by specialized devices such as HP RAID160 SA Controller:
HP RAID160 SA Controller Supported RAID Configurations

You have an usupported OS (or will be very soon...), but an interesting box, do you have a tape device on it? If so I would do a make_recovery tape (man make_recovery...) and use it to reinstall the OS on one disk (vg00) then mirror it and install the rest on 1 disk (vg01) and mirror also.
Since you have 2 independant controllers I would mirror each time a disk from alternate controller.
You could also try to stripe on 2 disks (each on different controller) then mirror with the 2 other disks left...

raidfile.conf

RAIDFILE.CONF(5)						    Box Backup							  RAIDFILE.CONF(5)

NAME

       raidfile.conf - Userland RAID for Box Backup

SYNOPSIS

       /etc/box/raidfile.conf

DESCRIPTION

       The raidfile.conf is usually generated by raidfile-config(8) but may be manually edited if the store locations move or if more than one
       disc set is required.

       discX
	   Specifies a set of discs.

	   SetNumber
	       The set number of the RAID disc, referenced by each account.

	   BlockSize
	       The block size of the file system (usually 2048). Under BSD with FFS, set this to your file system's fragment size (most likely an
	       8th of the block size).

	   Dir0
	       The first directory in the RAID array.

	   Dir1
	       The second directory in the RAID array. If you do not wish to use the built-in RAID functionality, this field should be set to the
	       same as Dir0. You should not use the built-in RAID if you have a hardware RAID solution or if you're using another type of software
	       RAID (like md on Linux).

	   Dir2
	       The third directory in the RAID array. The same notes that apply to Dir2 also apply to Dir3.
