Two oddities I notice so far:
1). I created a devclass with vola-vole then started the copypool
creations.
I subsequently added volf. While it has created volumes in volf, only a
few.
It seems to use a roundrobin algorithm and since it had created a lot
of volumes
before the devclass def was updated to include volf, volf has gotten
little use.
2).TSMMANAGER daily reports shows write errors to many of the volumes.
I think
this is generated when the 'volume' is full, because otherwise I can
view the contents
of the volume and the scheduled copyool creations completed
succ4essfully over the
weekend.

This looks good, but I would still create these volumes using define
vol
numberofvol rather than letting TSM create them.

Subject: Re: [ADSM-L] copypools on disk on AIX?
Yes, thank you.
After posting my question I went to the 5.3 Admin Ref and saw I needed
a
file type device class for copypools. Defined then, changed the
script,
and since TSM saw them as a new copypool it copied all the data over,
over this past weekend. about 2 TB of copypool data.
We just have the large volumes ( that are RAID5) on a DS4800. TSM auto
creates the volumes:
/var/diskpool/satacopyv- CPSATABG CPSATABG 2,048.0 0.0
Empty

We tried file device class with our onsite pool with disappointing
results.
I believe the problem was our decision not to stripe across LUN's.
This
would have made performance much better, at the cost of a LUN failure
causing more damage than if we used them indicidually. Now, I can't
remember the last time I saw a LUN failure, but YMMV. We will
probably
address this issue again when the decision is made to move our copy
pool
to disk.
