Cameron:
When I set up the system back in the beginning, the standard was to be
that any volume which was totally free was given a volume serial of
FRnnnn, where nnnn was its physical device address. Are you saying that
Alan or Rich are doing something different? David maintained this
standard as far as I know. At any rate, you can use any volume that has
volume serial of FRnnnn and if it contains anything that belongs to
someone, as far as I am concerned, they should have known to rename it.
If you are looking for free space on allocated volumes, use DIRM DIRMAP.

So when I see free that is not a sysprog assigned label, but an indication
of being uninitialized?

I don't think your seeing labels of 'FREE' - I think your seeing

Maybe we were confusing the term 'allocation'.. in any case - this DASD
would appear not to be used at all. VARY OFF aaaa and VARY ON aaaa and
then QUERY again to be sure. But if it shows FREE .. it is probably just
not initialized for use.

Is it a reliable method to label the volumes as FREE when you create
them,
but when you allocate them change the label to something else? That is
the
method we are using.

Available dasd is in the eye of the beholder. Here is how I look at
the
world.
If the dasd volume is in your LPAR's I/O configuration, it's "visible."
If a visible volume has been assigned to your VM LPAR it is
"available".
If an available dasd volume has been formatted so as to remove any
residual data and assigned a label, it is "eligible."
If an eligible volume has been placed in the pool of dasd that you take
from to satisfy system or virtual machine needs, it is "unallocated."
When an unallocated volume is subsequently allocated for use by CP, it
is
a "CP-owned" volume.
When an unallocated volume is allocated for use by one or more virtual
machines, it is a "user" volume.
A volume that is currently neither attached to SYSTEM nor a user is
FREE
according to QUERY DASD. You cannot reliably infer any of the above
roles
if it says FREE.
For example a dedicated user volume will show FREE until the user who
has
it logs on. Likewise for DEVNO minidisks.
And as Scott said, you may have visible dasd that are not available.
So it takes a good process to reliably track the life of a volume.

Subject: Re: [LINUX-390] Which DASD is free
Thanks Scott. What information is needed. There has to be a way to
determine which volumes you can use.
Thanks again.
