Reliant Unix and Disk Mirrors
Hi Folks,

This is already posted on Disk & Memory, will post under expert incase there is someone here who has seen this before.

This one has me a bit confused.

I have a large system running Reliant 5.45 with an EMC 3930 disk array fibre attached. As part of our requirement I implemented host level mirroring in addition to the BCV functionality provided by the 3930.

When the mirrors are split and the second mirror is mounted on a different mount point the size appears to be incorrect.

e.g. the mirror is vdisk302

/dev/vd/vdisk302 41943040 23017929 18877168 55% /ciblive/batch/production/files/dailey

the submirror is vdisk202

/dev/vd/vdisk202 4179408 2680498 1448144 65% /export_aix/ciblive/batch/production/files/daily

If the disk is unmounted and mounted again using the same command the info is correct.

The application is stopped while the mirrors are split and an fsck is run over the second mirror to ensure that it will mount.

Any one seen this before?

Rgds

bi2cf

BI2CF(6)																  BI2CF(6)

NAME

       bi2cf - a map conversion tool for Crimson Fields

SYNOPSIS

       bi2cf mapname [-p 1|2] [-f b|1|2|h] [-l] [-t mapname] [-i mapinfo] [-o outfile] [-d mapdir] [-O destdir] [-q]

       bi2cf {-h | -v}

DESCRIPTION

       bi2cf is a map conversion tool for Crimson Fields. It takes the data files of maps from Battle Isle, Battle Isle Data Disk 1 or 2, or
       History Line 1914-1918 and converts them into map sources usable with the cfed(6) map compiler for Crimson Fields.  bi2cf can handle both
       uncompressed maps and levels crunched with TPWM.

       For some units and tiles there are no corresponding counterparts in Crimson Fields. These cases are mapped to similar ones if available. As
       a result some maps will not be as balanced as the originals, others may be unwinnable, and still others may even fail to compile. If this
       happens the map in question needs to be adjusted manually.

OPTIONS

       -d mapdir
	  Set the location of the Battle Isle map files.

       -f b|1|2|h
	  Force map type to Battle Isle / BI Data Disk 1 / BI Data Disk 2 / History Line, respectively. Use this option when map format
	  autodetection does not work correctly. Maps from BI Data Disk 1 will always be detected as standard Battle Isle maps, so you have to use
	  -f 1 in that case.

       -h
	  Print a usage message on standard output and exit.

       -i mapinfo
	  Set map info message.

       -l
	  Skip last row and column of the map. This is necessary for maps from the PC version of Battle Isle.

       -o outfile
	  Write map to file outfile. Default file name is mapname.src.

       -O destdir
	  Set target directory for the converted map. This setting is ignored if a map name was given using the -t option.

       -p 1|2
	  Set default number of players for this map.

       -q
	  Run quietly. Don't print processing information on standard output.

       -t mapname
	  Set title and file name for the converted map. Default is maptype-mapname.

       -v
	  Print version information on standard output and exit.
