Re: [ADSM-L] NDMP - TOC? upgrade?
I figured I would reply direct to you since I am new to TSM and not
really sure if this is on target, but here is an article on TOC (and
Backup sets) when using NAS backups.
Looks like this problem (IBM reference: IC62418) was fixed w/ interim
fixes in 6.1.3.x and 6.1.0.x, but had trouble finding original IBM
article. Here is the cached google article for IC62418:
I'm not really sure if this helps you upgrade path problems, but maybe
it gets you a little closer.

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?
