Re: [ADSM-L] TSM level for deduplication

FYI - 7.1.1.000 is still on the FTP site. 7.1.1.100 is also on the FTP site.

Bent,

TSM 7.1.1.000 had a bug that sometimes caused restores of large files to
fail. IBM considered the bug serious enough to warrant removing 7.1.1.000
from its software distribution servers.

Hi Thomas,

when you are calling 7.1.1- an "utter distaster" when it comes to dedup then
what issues are you referring to?

I have been using 7.1.1 in a production environment dedupping some 500 TB,
approx 400 nodes, without any bigger issues for more than a year now.

Surely, there are still lots of "not-very-well-documented features" in TSM
7, and I am not at all impressed by IBM support, and especially not DB2
support and their lack of willingness to recognize TSM DB2 as being a
production environment, but when it comes to dedupping it has been smooth
sailing for us up until now.

Emne: [ADSM-L] TSM level for deduplication

My management is very eager to deploy TSM deduplication in our production
environment. We have been testing deduplication on a TSM 6.2.5.0 test
server, but the list of known bugs makes me very uncomfortable about using
that level for production deployment of deduplication. The same is true of
later Version 6 levels and TSM 7.1.0. TSM 7.1.1.000 was an utter disaster.
Is there any currently available level in which the deduplication code is
really fit for production use?

IBM has historically described patch levels as being less thoroughly tested
than maintenance levels. Because of that I have avoided patch levels unless
they were the only option for fixing crippling bugs in code we were already
using.
Is that attitude still warranted? In particular, is that attitude warranted
for TSM 7.1.1.100?

Has IBM dropped any hints about the likely availability date for TSM
7.1.2.000?
