You are aware that with TSM version 6.1 Lan-free is also formally
supported on GPFS? There was no code-change, just a formal support
statement, so you can get this to work with 5.5 as well....

As for HSM, I'd think that either requiests are so small that you
don't mind using TCP/IP or so large that you don't mind writing
directly to tape.

Hi,
I read about gpfs possibilities and would be happy use only it :)
But it's more complex.
I need make three-level storage system (fc disks-fata disks-tape).
First
level (fc-disk pool) contains user's data. Obsolescent data must
migrate
to second level (fata-disk pool), and then (if needed) to tapes.
All data must be transmitted over SAN. For all systems data-flow
will be
transparent, and by user request data must return to first level stg
pool.


How i see that solution.
HSM decides transparent data migration task.
TSM fo SAN can write only to libraries, so SANergy helps transfer
data to
disks (from fc-disks to fata disks and backwards).
And at end TSM for SAN is responsible for transmitting data to tapes
(if
need send it from client) and back.
But i don't know - will this work? :)

In fact, intend using AIX (HACMP) for TSM server and Client systems.
As i
know SANergy may works well on AIX. :)
But now, I have only linux and windows systems on ESX preparing
demo-solution, and also all issues and problems connected with
change of
platform :).

Re: [ADSM-L] SANergy MDC on Linux (CentOS)






Hi,

I think you'll learn that GPFS provides everything SANergy does, plus
reliability and some more neat features. I don't think you'll actually
need the SANergy MDC to do what you want to do. I have a very strong
opinion on SANergy, and that is that you don't want to use it, not
even if your life depended on it (and if your life does depend on
sanergy, boy, you're in trouble ;-)).

Anyway, we might be better able to help you if you'd tell us what your
final goal (in terms of functionality) is.

Hi,
I try configure HSM and SANergy on linux. And i couldn't install
SANergy
MDC on CentOS.
First i tried install all on CentOS 4 (2.6.9-78). In IBM
documentation i
found than MDC works with linux kernel 2.6 only if filesystem EXT3
type.
But HSM needs gpfs filesystem =(.
So I decided install another linux system CentOS 3 (it has kernel
version
2.4.21-50.EL) and there install MDC. But installation writes that :
The SANergy MDC will not be installed.  This kernel is not supported.
Only the client will be installed.

what may it need else? or what is my mistake?
may be there are more simple ways to make HSM with SANergy?
