Re: [EXTERNE] [ADSM-L] CentOS alternative on TSM V8.x => RockyLinux :+1:

[Bjørn Nachtwey]

Hi,

I'm running my first servers using RockyLinux 8.5 -- it works well, 
LinTapes 3.0.59 also without any problems using kernel 
"4.18.0-348.12.2.el8_5.x86_64".
Some packages differ from RHEL8.4 so I could not just copy the list of 
installed packages.


As far as I remember, you'll need to use the >>-vmargs 
"-DBYPASS_TSM_REQ_CHECKS=true"<< option during install as RockyLinux is 
not officially supported ;-)


best

Hello Zoltan,

thanks for the answer...

Yes for sure lin_tape drivers is has to be installed on supported 
kernel, I had a long experience installing them when I worked for IBM, 
also tried to recompile some free versions.


I didn't ear about this distribution but I'll test it... many thanks

I'm personally unlucky with the Ubuntu is so different from Redhat 
fork and have no time yet to learn about it (home in the future).



Have a Nice Day.


Grazie
Maurizio

Rocky Linux is an open-source enterprise operating system designed to be
100% bug-for-bug compatible with Red Hat Enterprise Linux®. It is under
intensive development by the community.

Hello Maurizio !

Our shop is very happy with the migration from AIX to RHEL 8.5 (on
bare-metal x86 servers) for our TSM 8.1.12 ...

Costs a bit of money, but quite a bit less than TSM !

Coming from AIX, I expected Red Hat to be lesser value with regards to
"how-to" support.  Amazingly enough they are quite good at anything 
we're
throwing at them...  They even assisted on a ReAR issue (which is a 
great

tool for restoring Linux systems from TSM)...

We already have an installed base of >400 RHEL servers so the curve is
nonexisting.   Using on-premises Red Hat Satellite for subscription and
patch management.

Hello Luc,

thanks for you message :) .
I also come form the AIX World and I known how this systems powerful are.
Actually I don't have the "privilege" to be on those systems, the covid 
period require some cost effort to restart the business as before, the 
question about the OS was about this situation.
RedHat is good but for the actual test environment goals to expensive, 
also without support subscription.



Have a nice day.

Maurizio
