We use file device classes for TOC.  No problems.  NFS mounted data domain
storage.   Maxcap of 400GB.  We have several TB of toc data and don't have
problems except for hating life when I have to do a restore.   It works
fine, just can be painfully slow if you have very large TOCs (file systems
with 20million+ files)

I haven't looked into the v6 upgrade process yet, but I would try and
pursue the standard upgrade for the library manager/NDMP instance, then
use export for everyone else.   I was under the impression the standard
upgrade process would work for ndmp data.

Regards,
Shawn

Subject
[ADSM-L] NDMP  - TOC?  upgrade?






Environment:  AIX 6.1, TSM 5.5.4

We've been backing up a couple of NAS filers via NDMP for around 18 months
but recently find that sending the data to a storage pool of 12 500G
rlv-formatted disks has been diagnosed by L2 as the cause of occasional
problems with the recovery log when it changes volumes -- holding the
recovery log too long and crashing the instance.

The rlv disk data has been moved off in preparation to rebuild the disks
as FILE devclass volumes...but think I remember reading something about
TOCs being troublesome/incompatible with that config?  Since one of these
NAS boxes has millions (literally, I'm told) of small documents --
versions of which are required to be kept forever -- TOC is a a
'must-have' for file level restore, else we would have to restore the
whole filesystem, the largest of which has about 5-6TB in use.

Is anyone using NDMP writing to file devclass with TOC successfully?  (any
suggestions on MAXCAP?  default is 4M which seems 'small')

Side issue:  think I heard there's no data export upgrade path for
NDMP...'take a fresh full backup' isn't going to work for millions of
keep-forever documents...we are planning to move to AIX 7.1 and TSM 6.2.x
later this year when the new hardware arrives so this will be upon us
soon.  Any comments/ideas?

Thanks, Susie
