Sorry for the confusion. I think they way I wrote that was a little hard
to follow.
To reduce some of your effort, just DETACH and LINK rather than LOGOFF
and LOGON.
Seeing you're using DIRECTXA, here is a recipe for in-place expand:
* define 10 cyls after the existing minidisk, call it 992
* DIRECTXA that update so CP knows about it
* link to the 992 minidisk and FORMAT it (to get it blocked, in case
it is not already)
* detach the 992
* redefine the 991 as 20 cyls, removing the temporary 992
now 991 occupies all 20 cyls but starts at same as it did originally
* DIRECTXA that so it's online and CP knows
* release the 991 and detach it
* re-link the 991 and access it
* Q V 991 to confirm CP is giving you all 20 cyls
* FORMAT (RECOMP
FORMAT (RECOMP should detect the number of cylinders it gets from CP and
give you the full 20.
I HAVE NOT tested the above steps, but have tested FORMAT (RECOMP in
similar change-up.
The only tricky part to expanding a minidisk in place is that the new
storage must be blocked same as the existing cylinders.
