We have an IBM server with 2 scsi drives which are mirrored. We needed
to increase capacity so we bought 2 70gb drives and replaced them in 2
stages so letting the raid rebuild the added drives - we expected this
to increase the capacity after the 2 swaps but all we have now are 2
70gb drives as 1 logical drive as expected but with the original
capacity of 30gb. I have tried Paragon Partition manager enterprise
server to increase the size but this also thinks the drives are just
30gb. What can we do to fix this - it is getting irritating now as I
have tried everything I can think of.

This behaviour is exactly as it should be. Otherwise you would run into
problems if you have replacement disks that are large, but do not
want the RAID to change its parameters.

The thing you need to do is to create a new RAID array with the
new capacity. Then you put new partitions and a new filesystem
on it and/or restore via your backup mechanism. This is, BTW, a
good opportunity to find out whether your backup mechanisms work.
