Cameron:

As Tomas suggested, you will be assigning complete disks to each user,
so the easiest approach (at least for the 700 and 701 addresses) is to
find unassigned disks and then format them and assign them to each user.
Check with Rich or some other LINUX type as to the kind of formatting
needed. It has been so long since I formatted any of these that I have
forgotten the requirements. You should have enough free devices to do
this. All the devices are 3390-9s (10017 cylinders). We started with 439
of these volumes. I don't know how many have been taken already, but
there should be enough (80) for your 40 users still free. As for the 191
disk space, these will have to be individually assigned in DISKMAP.

I'm kind of surprised that each LINUX user needs 2 full 3390-9 volumes,
but if that's what the LINUX guru is saying, then so be it.

What is the status of the 8100? There's a huge amount of additional disk
space available there, but last I heard (several months ago), it was
just getting powered on. I'm pretty sure we have no connected channels
to it, since I haven't been asked to update the IOCDS, so it can't be
used, although it may have been potentially formatted from its own HMC
function. Have any FICON cables ever been purchased? Has any plan for
connecting and formatting the 8100 ever gotten started?

My question: Disks 191 and 900 are exactly  the same for both users. For
disks 700 and 701, the disks where Linux is going to live, the disks are
different slightly in their labeling: 700 is MM2101 on for user LINUX001
AND MM2104 for user LINUX002, etc.  I know how to use DISKMAP somewhat. But
I'm not completely clear about how to apportion DASD for these users. I
sure don't want to overwrite an address and I know DISKMAP will warn you
about overlaps but I would hate to mess up the addressing. I was with the
VM sysprog when he defined these, but I forgot exactly what I'm supposed to
do.  Do I find more minidisks labeled MMxxxx and assign them sequentially
in DISKMAP?  I have never allocated DASD before. I am going to need about
30-40 guests and I have the DASD for it.

Thanks!
