Re: Full backup?
Hi Dave, I assume that you'll be using a test TSM server that has been created by restoring a backup copy of the production server's TSM database. My scenario implies that you'll have to make a production TSM server db backup after you created the special copy storage pool volumes for the node. I'm not sure I follow how getting "... two other nodes up and running" is not a client test. If you are just looking to verify that the TSM *server* was restored correctly, you could probably bring one tape with you that has one (or a few) of the node's files on it, and try restoring those files, without doing anything else special. That is less messy than manipulating your schedules to try and get a "full" backup. There are almost certainly other ways to manipulate your production TSM environment to generate a smaller set of tapes, but not all methods are quick (e.g., collocation, if not currently in use), but as my earlier response suggests, there is the bigger question of what it is you are really trying to accomplish. If your DR test is intended to verify that you can restore a working TSM server and you demonstrate that by restoring a few client files, that's one thing. But if your objectives also include trying to restore a complete client node from the restored TSM server, then I think making a special backup just to reduce the number of tapes invalidates the DR test (at least for that specific objective), since it does nothing to demonstrate that your regular backup processes are adequate for restoring the client node in a disaster situation. For example, if you are *not* currently collocating, then doing a test with your non-collocated tapes might help make the case for collocation if the restore time is not satisfactory. So... if you want to restore just a small handful of files to validate the restored TSM server is working, then why not just bring one or two of the existing tapes with you (that are known to contain at least one or two complete files without spanning to other volumes) and restore those files as a quick test? If you want a rigged restore, then my other idea should also work: use a new node name, which will automatically get a full backup. You can define the node in a new (test) domain, and create a special tape storage pool for this test node. Define a management class that puts all this node's data in the new storage pool, then run a backup. The result will be a small (or smallest possible) set of tapes in the test storage pool that you can take with you. Of course, you'll want to then make sure that you bring a TSM server database backup with you that was made *after* this special client backup was made. The idea of using a scheduled SELECTIVE command against the / file system only works if / is the *only* file system; otherwise you'd need to enumerate all the file systems that are on this client. And you'dl have to also use the -subdir=yes option.

You need different procedures for different possible disasters; Procedures needed to restore back to the same machine after a hard drive failure, are simpler than the case where you are restoring to different hardware at a hot site. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Tim Brown Sent: Monday, November 28, 2005 3:25 PM To: ADSM-L@VM.MARIST.EDU Subject: TSM Bmr ??

Re: TSM Journal Service communication failure
Uwe - Those messages are helpful... Windows error 233 is ERROR_PIPE_NOT_CONNECTED, which says "No process is on the other end of the pipe". Assuming that the dsmerror.log message was written by the B/A client, it means that the Journal Service disappeared (died). Perhaps the Windows Event Log tells why (possibly a space issue?). In any case, restart it, and keep an eye on it to see if it consistently fails under similar conditions.

select volume_name as Volume,last_write_date -

Re: Full backup?
It's only "cheating" if the objective of this DR test is not to validate your current client backup process. If it *is* intended to test your client backup procedures, then yes, it is cheating on a far larger scale than just limiting the number of tapes you bring with you, since you avoid testing with the real data that you would actually have at the time of a real disaster, and therefore won't find any issues that might fall out had you had the real set of tapes. You also don't get your money's worth for the cost of the test. (Obviously) I do not recommend this course of action. :-) But if you must, then it might be easier to just register a new node and make a full incremental backup of that node. I haven't worked it out in full detail, but a compromise would go something like this: create a new disk storage pool, and use MOVE NODEDATA to move the test node's data to that pool. Then create a new copy storage pool, and back up the disk pool to it. You can then migrate the data from the new disk pool back to the regular tape pool, then delete the new disk pool. Likewise, after you've completed your DR test, you can delete the new copy storage pool and its volumes. Your DR test won't use the original set of tapes that it would use in a real DR test, but at least the backup data would be the same as what you would have in a real DR scenario.

Re: SQL select for file size
But why do the volume names need to be known at all? Why not just do: select node_name,filespace_name,file_name,file_size from contents But yes, if the file is part of an aggregate, you'll get the aggregate size, which would be misleading. I don't think there is a very good way to do this. Another avenue to consider would be just get file counts from the BACKUPS table, then multiply some average size value, say, like 3 - 5 MB for a typical song. It's only a rough idea, but then if the objective is to determine who the biggest users of these files are, the file counts should give an indication.

I've never seen that behavior - that would result in a large number of tapes in Filling state, and that does not happen. TSM requests a fresh tape when the would-be candidate filling tape is in an unusable state (as from previous tape errors) or that volume is in use (current output volume or being dismounted). If a TSM instance was always calling for new volumes, that would constitute a violation of its design, and should be reported as a defect. In any case, this thread is largely proceeding without substantive information. We need to see the results of analyses which examined tape states, Activity Log, and volume contents. Richard Sims
Re: 3592 Tape Compression
If any of your clients have compression on, the data is compressed before sending to the TSM server. When TSM sends it out to the tape drive, it cannot be compressed again (or by very little). This is true of any type of compression, with any type of drive. If you have a mixture of clients compressing & not compressing, there is simply no way to calculate your true compression ratio on the drives. The only way you can calculate is to set up a controlled test, where you are sure none of the client data is compressed. But as others have mentioned, the compression ratio is very dependent on the type of data.

Re: Space Reclamation Eating Tapes
It has been my experience that, if primary tape pool maxscratch value is set greater than tapes used when reclamation kicks off, it mounts a brand new scratch tapes. I suspect that there is some logical reason how tapes are reclaimed ... such as why not taking already used tape. However I have had success by lowering the maxscratch count less than tapes used will allow TSM not to use new scratch tapes but use already used tapes. Now, if one is using collocation, I tried to think of a reason why one would starting reclamation. My experience shows that since any gain of tapes by performing reclamation of collocation pool is short lived because TSM will shortly attempt to use new scratch tapes. Sung Y.

Re: HP itanium and 64-bit support
Yiannakis, Briefly, IA64 (Intel Architecture-64) is a 64-bit processor architecture jointly developed by Intel and HP. It is distinct from and not directly backward compatible with X86 architectures due to use of a different instruction set known as EPIC. There's plenty of online reading material at the HP and Intel sites which I'd encourage you to check out, since this is kind of off-topic for this discussion list. The important thing to note is that there are two different 64-bit hardware architectures, IA64 and X64. Be aware of this when selecting a 64-bit TSM client. Others on the list may have different suggestions for your second question, but I can see two approaches. The first would be to install SQL Server 2000 and use the existing (and functioning) TDP SQL client for backups. You can upgrade to SQL Server 2005 later. Or, install SQL Server 2005 and use SQL's built-in backup capabilities, and then use a BA client to backup the flat files. Neither is optimal. You also may just want to call Tivoli support for assistance. Hope this helps. --Ruth Mitchell Cornell Theory Center -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Yiannakis Vakis Sent: Monday, November 28, 2005 2:02 AM To: ADSM-L@VM.MARIST.EDU Subject: Re: [ADSM-L] HP itanium and 64-bit support Ruth hi, First of all what is an IA64 ?

Re: 3592 Tape Compression
Volker, True compression ratio is data-dependent. The more redundant information is found in files, the higher the ratio is For your data it is only '1,4'.

Re: Change / upadate tape path
Hi, You need to define a amnagment class with a copygroup that points to the new storage pool, or update an existing managment class copygroup, the parmaeter is 'copydestination' Then, in the include/exclude list for serverA include the files you need to go to storagepoolB to the new/updated managment class. Alternatley, you can define a default managmnet class in a new domain, and place the serverA node in that domain. As the managment class will then be the default, you will not need an include statement in your include/exclude list. Matthew. http://tsmwiki.com/tsmwiki -- Matthew Warren.
