Rebooting redundant VIOs and mirroring of PVs they serve to client LPARs

need to confirm: we have a system with two VIOs each serving a partition on a local disk to a client LPAR. That client LPAR has them both in a VG which is mirrored (exact). So each disk has a copy of the client LV that the client VG supports. This is the setup that was bequeathed to us by the...

MKFATIMAGE16(1) 					      Make HDIMAGE for DOSEMU						   MKFATIMAGE16(1)

NAME

       mkfatimage16 - generate a virtual drive image suitable for DOSEMU

SYNOPSIS

       mkfatimage16 [ -b bsectfile ] [{ -t tracks | -k Kbytes }] [ -l volume-label ] [ -f outfile ] [ -p ] [ file...  ]

DESCRIPTION

       mkfatimage16 creates a hdimage file for DOSEMU that is pre-loaded with the files specified on the command line.	The output is either writ-
       ten to stdout (hence do not forget to append " > hdimagefile", else you will see garbage on the screen) or to the file specified by the	-f
       option.	For  the  latter  you may also use option -p in order to force padding up to the given size. This padding will result in so-called
       holes on an ext2-FS, hence the actual disk usage will not be greater.  The file created by mkfatimage16 then  can  be  used  as	a  virtual
       drive, when defined in /etc/dosemu.conf.  As long as -k is not given, the number of heads is always 4 and you have 17 sectors per head else
       it is adjusted accordingly.  To vary the size, you may either use the -t option or specify the total amount of Kbytes via -k option.

       All files given behind the options will be copied onto the hdimage. In addition a DOSEMU suitable master boot record (MBR)  is  established
       and via option -b you may specify a boot sector that gets inserted as first sector of the partition. To later access the hdimage outside of
       DOSEMU you should use mtools (/etc/mtools.conf parameters partition=1 and offset=128).

OPTIONS

       -b file
	      Insert the first 512 bytes of file into the bootsector of the partition.

       -t num Make the virtual disk have num tracks. This is the one way to define the size of the disk.

       -k Kbytes
	      Make the virtual disk be Kbytes in size. Using -t and -k are mutual exclusive.

       -l label
	      insert label as volume label for the disk.

       -f outfile
	      The hdimage is written to outfile instead of stdout

       -p     Pad the hdimage with zero up to the total size given by -t or -k (only in conjunction with -f).

BUGS

       This program doesn't support name mangling and does very little checking for non-DOS filenames.	Disk full condition  isn't  detected  (and
       probably causes erratic behaviour).  Duplicate files aren't detected.

AVAILABILITY

       Comes with DOSEMU
