Re: [ADSM-L] Dev Class type FILE with multiple directories

Keith,
the difference is that you are using pre-defined volumes - which the doc
says will be used in alphabetical order - see the worked example at the
bottom of the technote (steps 1 - 8 ). The true round-robin across
directories only works when using scratch volumes (that are auto-created
on demand).

Rick,
I am just getting started with FILE deviceclass storage pools, so take the
following with ample grains of salt. However, my experience contradicts
swg21497567. Or, I might misunderstand that Technote.
This is a TSM 6.2 RHEL5 server. The file deviceclass has fourteen 2 TB
filesystems on raid10 ldevs. Volumes were predefined to the storage pool with
'wait=yes', so they were created one at a time in round-robin order across the
filesystems.
A small amount of client backups are being written to the file pool at this
time, so it is clear how volumes are being used. Client backup files are
written to the storage pool in volume name order, not in filesystem name sort
order. Today I see one full volume in each directory, and many empty volumes.
If the Technote applied, all full volumes would be in the first directory.
Ås far as I know,
Keith
