Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Del Hoobler]

Hi Zoltan,

When you upgrade the server, the updated clients will be allowed to 
connect the first time (trust on first use) and automatically exchange the 
certificates.

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Zoltan Forray]

Del,

Glad to here there should be no issue in upgrading the clients to 7.1.8 or
8.1.2 before the servers are upgraded.

So, what can I expect when I upgrade the servers to 7.1.8 / 8.1.2/4 as for
the certificates?  I realize I have to run the utility to convert the
server cert.kdb file to cert256.arm (eventhough I have never used SSL on
any of my TSM servers, the file exists and I had this problem on my test
server when I upgraded it to 8.1.3).

Will the clients that upgraded to >=7.1.8 properly/automatically exchange
the required certs once the client realizes it is talking to a server with
the right "language" or will that be a manual thing? As most folks, I plan
to keep SESSIONSECURITY TRANSITIONAL as long as possible, easing into it as
gradually as possible.

But if upgrading to >=7.1.8 is going to require manual updates to get the
certs right, I would rather hold off.  Right now it is manageable.

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Del Hoobler]

Hi Zoltan,

It's fine to upgrade the clients first... you won't see warnings because 
the clients know they are talking to a back-level server and will speak 
the right "language". The best practice is to upgrade the servers first so 
all the certificates are there and it will make sure the security issues 
are addressed, but it is not required. 

We understand the gap with regards to the web interface. We are evaluating 
possible ways forward for that.

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Loon, Eric van (ITOPT3) - KLM]

In fact a q server f=d shows Session Security: Transitional, but each time I 
log on to the server using the admin command line, my admin userid is getting 
updated from transitional to strict! Upd admin transitional works but as soon 
as I log on it's being switched back to Strict.
Kind regards,

I concur. I remember having this same problem when I upgraded my test server to 
8.1.3 eventhough the docs say "transitional" is the default.

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Del Hoobler]

Hi Eric,

Once you connect with a "trusted" client and the certificate is 
distributed, the mode is set to back to STRICT. The idea is that 
userid/adminid now has the certificate, it must supply it when you 
reconnect to verify you are who you say you are. 

You could reset the admin back to TRANSITIONAL and do the same thing for 
the second machine.

upgraded
to 7.1.8, but it was kind of surprising for the folks that still used the
down-level client. Fortunately there were no dependencies that prevented

It seems that the BA client was more tolerant of the SSL changes than the
admin client, though; I don't remember any client backup problems after the
server upgrade.

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Zoltan Forray]

Del,

Thanks for the info. Some of it is useful and I have seen most of it.

I have a question about the reverse i.e. clients who have upgraded to
8.1.2+ and 7.1.8.There was this dire warning in the 8.1.2 upgrade docs
about upgrading your servers before installing 8.1.2 clients or your
backups would fail.  I downloaded all of the latest clients and eventhough
I sent an email to my co-workers about *NOT* using 8.1.2/7.1.8, some
ignored me and installed 8.1.2 (and then 7.1.8) with no issues I am aware
of (remember all of my servers are RHEL 7.1.7.300).

At what point do these dire warnings kick-in?  Is it safe to deploy 7.1.8 /
8.1.2 (holding off on 8.1.4) throughout my complex without fears of
mass-destruction?

Plus the issue of the "BA web interface" going away (if I understand this
correctly) is a major problem for us.  Unless of course I am completely
misunderstanding and it is only the web Administrator interface (which we
don't use).

>>>admin to sessionsecurity=transitional (strange, this should be the
default...) and now I could start a session successful.

I concur. I remember having this same problem when I upgraded my test
server to 8.1.3 eventhough the docs say "transitional" is the default.

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Loon, Eric van (ITOPT3) - KLM]

Hi Del,
Well, not really... I'm currently installing a 7.1.8 server and noticed that I 
could no longer use a 7.1.7 admin commandline:

ANR0404W Session 22 for administrator ADMIN (Linux x86-64) refused - client is 
down-level with this server version.

So I upgraded it to 7.1.8, but it was still not working:

On the client side: ANS1592E Failed to initialize SSL protocol.
On the server side: ANR3335W Unable to distribute certificate to KLM35757 for 
session 24.

So I updated my admin to sessionsecurity=transitional (strange, this should be 
the default...) and now I could start a session successful. I tried the same 
admin account on another TSM client and again On the client side: ANS1592E 
Failed to initialize SSL protocol. A q admin f=d showed that sessionsecurity 
was again set to strict! I'm lost...
Kind regards,
Eric van Loon

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Zoltan Forray]

I agree with you about the lack of completely clear information.

I have a test server that I upgraded to 8.1.3 and with the default
SESSIONSECURITY
value we had mixed and inconsistent results with the few clients I tested.
We also had to go through the key conversion process even though (IIRC)
docs said we shouldn't have to since we never used encryption or SSL on any
server (except for the lone LM server that creates off-site tapes which are
encrypted).

And the whole issue of the web interface going away is really confusing and
will cause us issues since we have processes that require the web interface
to access node backups (no way around it). We haven't had a chance to test
what will happen in that scenario due to lack of people time and too many
active projects.

Subject: Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

Test! Test! Test! Search this forum for previous posts about this. There
are a bunch of gotchas. Perhaps one of the most severe is what happens to
administrator IDS. Create some dummy admin IDS to use in testing, because
you can permanently disable your own admin ID if you're not careful. We
also know there will be library sharing gotchas.

We're actually going to do the backup servers first - after thorough
testing. We think we can minimize the risk to things like admin IDS if we
upgrade the servers with NO clients yet on 7.1.8. I think that having 7.1.8
clients around will greatly complicate the process of upgrading the
servers, especially if any of those 7.1.8 clients are the desktop
workstations used by you and your coworkers. It's possible that when you do
eventually upgrade your servers to 7.1.8, you'll have to backtrack to each
client and manually install new SSL keys, on all client systems, all at
once. I hope that cat-herding nightmare can be avoided by upgrading servers
first, which will then manage key distribution among clients more
gracefully, as they upgrade to 7.1.8 one at a time. If I'm wrong about any
of this, please chime in.

This thing has a big effect. Careful testing is necessary.

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Zoltan Forray]

I too am looking to upgrade all of my servers from 7.1.7.300, soon.  I went
through the documents in your link (IBM - one of them 404's).  My first
concern would be upgrading the offsite replica server. While there is
documentation about library manager/client  server levels/compatibility
(pretty sure need to do LM servers first), does the new forced security
require SSL/TLS for server-to-server communications?  If I upgrade/update
the replica server to 7.1.8, will that kill it's communication with the
5-other 7.1.7.3 servers that aren't talking SSL/TLS?

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Tom Alverson]

Thanks for that link, I am more worried about any "gotcha's" caused by
upgrading the client to 7.1.8 or 8.1.2 before the storage servers get
upgraded (and start using the new authentication).   What I had not
realized until I saw the chart is that the new clients are NOT backward
compatible with old storage servers (which doesn't really affect me since
we have those all at 7.1.7.2 now).

Re: Should I upgrade to 7.1.8.x ??? (on the client end only)

[Skylar Thompson]

There's pretty wide version compatibility between clients and servers; we
didn't go v7 server-side until pretty recently but have been running the v7
client for a while. IBM has a matrix published here:

http://www-01.ibm.com/support/docview.wss?uid=swg21053218

For basic backups and restores I think you can deviate even more, but
obviously you won't get support.

Should I upgrade to 7.1.8.x ??? (on the client end only)

[Tom Alverson]

Our TSM storage servers were all upgraded last year to 7.1.7.2 (before this
new security update came out).   Now I am wondering if I should start using
the updated client or not?   If the servers stay at 7.1.7.2 for now is
there any harm in using the newer client?  I would have to use 7.1.8.0 on
anything older than 2012.  I saw some email traffic earlier that once you
use the new authentication mode on a node you can't go back?  But it seems
that would not be possible until our storage servers get upgraded.

Is there any downside in my case (where the storage servers are still at
7.1.7.2) of using the latest client versions in the interim??  Our current
standard client versions now are 7.1.6.4 for 2008 and older, and 8.1.0.0
(yes the horrible buggy one) on newer servers.
