Hello David,

You need to increase the maximum allowable file on your system. For AIX, you
use the "ulimit" command. To see what the current limit is, issue:

   ulimit -f

This will tell you (in blocks) the maximum allowable file size. To change this
value, enter:

   ulimit -f nnnn

(where 'nnnn' is the maximum number of blocks)

         or

   ulimit -f unlimited

It is important to note that the largest volume (ADSM volume, not hard disk
size) you can use with ADSM is 2 GB - 1, i.e. 2,147,483,647 bytes. So when
running dsmfmt, you might specify:

   dsmfmt -m -data /adsm/datavols/bkup01.dsm 2047

Subject: DSMFMT and DISK VOLUMES

I'm trying to allocate a disk file to ADSM using dsmfmt.  I have a
2.040GB drive on which I have allocated a 2.040GB filesystem.

I've tried allocating a 2GB file, and that does't work (error
code=27; I assume that there's not enough space in the
filesystem).  I've tried allocating 1.88GB, and still no luck. So I
allocated a 1GB file successfully.  So the maximum file size I can
use is somewhere between 1.0GB and 1.88GB.

Is there a formula for determining the largest storage pool file you
can create in a filesystem?  I'm getting tired of guessing!

Thanks in advance for the help.
