SANergy MDC on Linux (CentOS)
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? Best Regards, Khramov Gennadiy gkhra...@computel.ru
Re: 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.

Re: SANergy MDC on Linux (CentOS)
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: SANergy MDC on Linux (CentOS)
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.

Re: SANergy MDC on Linux (CentOS)
Yes i found that tsm lan-free 5.5 woks with gpfs. But in real model gpfs wouldn't be used, that's why i looking for another ways. Well, files not so small for transfering over TCP/IP, but consumer needs fast access for recently migrated data. So he determined such conditions and set task and I solve it. Though decision of this problem interesting per se. I've tested that SANergy works with TSM BA Client well (who would doubt :) ), but my chief dosen't sure that HSM will works also fine. Do I correctly understand, that HSM uses TSM BA Client functions for transfer migration data (all options for hsm declaring in clients dsm.sys)?
