locate files in the tsm database

Re: locate files in the tsm database
Hi Henrik, Try something simple, like: select NODE_NAME, FILESPACE_NAME, FILE_NAME, FILE_SIZE from CONTENTS where FILE_NAME like '% init.dat' This should find all instances of 'init.dat' whether backups or archives. I'm sure you could probably format this better, but the bare bones are there :o) Anyone else with any advances on the above?

CopyStoragePool tapes not expiring?
Hi, I seem to have a problem with some of my 'copystoragepool' tapes. Whenever i check out these tapes, I update the volumes as access=offsite, but it seems that when the original tape expires, they do not. See below for an example. SA2_006 already has 0.0% Pct Util and has a volume status of 'Empty' but when I tried to check the tape in a scratch volume, TSM does not allow me to do it. Can anyone suggest a solution? I'm out of scratch volumes already. Not a good thing. :-( Thanks in Advance.

Re: TSM backup of MS Exchange
I do MS Exchange backup using TSM's TDP for MS Exchange. On TSM admin command line when I issue query filesp nodename f=d it gives me following output. Capacity (MB): 0.0 PCT Util: 0.0 Is this correct? Or it is not doing any backup? On all other UNIX and Windows clients these two have numbers related to filesystem size.

Re: Scratching empty tapes
You might post q vol and q libvol... I assume you know about the MAXSCRATCH parameter on the storage pool...

Until now TSM run's on MVS. I have defined one sequential Storagepool, which is connected with a 3494 ATL. The maximum Scratch Volumes are set to 45. There is one client defined. Every day I checked the number of volumes in the Storage Pool and wonder why so much volumes are needed. I checked it and wonder. At the Storage Pool are 49 volumes. 37 of these volumes have the status 'empty'. Count TSM only the volumes wich are 'full' or 'filling' when it checks the 'maximum scratch volumes'? I think normaly it must say 'hey dude, storage pool is full'. If the storage pool needs a volume, take it first the 'empty' volumes or scratch tapes? If I define a second storage pool, is it able to get a 'empty' volume from the other pool? Is it possible to change the status of the 'empty' volumes from private to scratch with automation or must I do it manually? At Administrator's Guide I can't found a answer. TIA Wolfgang

Re: Restore MS Exchange data to a different machine
With TDP for Exchange V 2.2 it is supported and it works !!! We have restored data from an Exchange/2000 server to another Exchange/2000 server with another name. The trick is to specify the TSM-nodename of the FROM-server when you restore on the TO-server. For instance: tdpexcc restore Storage Group C FULL /Mountwait=Yes /MountDatabases=Yes /excserver=TO-server /fromexcserver=FROM-server /TSMPassword=TSM_PW FROM-server /tsmnode=TDP-TSMNodename FROM-server In our case this worked just fine Success.

Re: Restore MS Exchange data to a different machine
Sure it can be done. It took me over 3 weeks to get it to work.. Of course you need to be running all the same versions and service packs for both TSM TP for Exchange (2.2 for me) and Exchange 5.5 (sp4) or 2000 on both machines. Do a full backup of your email server. Go to the restore server and do a restore of the mail (make sure erase existing logs is CHECKED!), but DO NOT restore the DIRECTORY, only the information store, private and public. Then after the restore restart the services for exchange and go into the Administrator program (see tech net article ID Q146920 for full details) Go into Server Objects, and then select Consistency Adjuster Under the Private Information Store section make sure Synchronize with the directory is checked, click All Inconsistencies and away you go. This will rebuild the user directory whole list and all the mail. My config is Windows 2000 adv server Cluster using exchange 5.5 (sp4) and TSM v2.2 (Data Protection) - for the main exchange box tsm v4.1.3 server Restore box is windows 2000 adv server no cluster with exchange 5.5 (sp4) Joe Cascanette -Original Message- From: Yahya Ilyas [mailto:[EMAIL PROTECTED]] Sent: Wednesday, August 29, 2001 6:18 PM To: [EMAIL PROTECTED] Subject: Restore MS Exchange data to a different machine Is it possible to move MS Exchange data from one Exchange server to another?

TSM DB/Disk Pool - Disk tuning question
I have TSM Server 3.7.4.0 on AIX 4.3.3. I am going to be redoing my disk storage for this machine and have basically two questions. if someone knows the details of how this works. 1. The Disk Storage pool I have is 110GB. Most of the time it is between 20 and 70 percent full - mostly less than 50 percent. If I have this split into say 10 volumes, each on a separate hard disk, does most of the activity stay on the lower volumes and rarely on the higher ones? Logically I see this as a coffee cup with a slow leak. The bottom is almost always wet, the top rarely. Is my assumption correct? Basically I would spread the volumes over the hard disks to even out disk access. 2. Same basic question about TSM DB. It is 13GB and 65% utilized. I imagine like a regular database it is spread out over the 13GB and has more or less even access if spread out over several disks. Correct? (With my current system the way everything is laid out now I can't use things like iostat to prove/disprove this, and I didn't seem to find this specific topic mentioned in manuals.) Thanks, David B.

Anyone have a script to install win95/98/me/2000 4.1/4.2 scheduler without using wizard?
Hello, I want to install the scheduler without having to use the wizard. Is there an unattended install doc somewhere? I guess I see a .bat file that runs and just installs the scheduler with certain default settings The bigger picture is that I am using pkzip + self extractor to allow the user to simply click on the .exe file, which will then extract the TSM files to a staging directory, and then prompt the user for the TSM ID and server name(using visual delphi), this will then write the OPT file and kick off the install process. I pretty much have this part working what I need is a short script that will install the scheduler after the install is complete Thanks for any and all help. Keith
Re: Disappearing Tapes
Are you also sending out your database backup tapes? If so, do you have a schedule in place that regularly deletes old database volumes? If you do, this would explain your situation. If you send a database volume offsite, it will not show up in a query volume or query libvolume command. The only way to see them is to query the volhistory. If you have a scheduled clean up of the database volumes , they will be automatically deleted from the volhistory (The only way to delete a DB volume). This will result in tapes being kept at the off site vault with no records left to identify them. I hope this helps.

Cannot delete tape in empty status... media state is incorrect
Here's a puzzle for you all... I just yesterday upgraded from TSM 3.7.3.0 to 4.1.4.1 on AIX 4.3.3. All went well, and I haven't seen any problems except for this: I discovered a tape in my library that is EMPTY, but it has not been changed to scratch. Details of this tape's status are below. If I try to update the status to scratch (upd liv atl dbr086 stat=scr), I get this: 08/30/01 11:13:05 ANR8443E UPDATE LIBVOLUME: Volume DBR086 in library ATL cannot be assigned a status of SCRATCH. If I try to delete it (del vol dbr086), I get this: 08/30/01 11:15:08 ANR1425W Scratch volume DBR086 is empty but will not be deleted - volume state is mountablenotinlib. As you can see below, the media state according to Q MEDIA is MOUNTABLE IN LIBRARY, yet the delete fails because it is MOUNTABLE NOT IN LIBRARY. It looks to me like my database is somehow corrupted.

Re: TSM DB/Disk Pool - Disk tuning question
David, In answer to 1), No, in my experience the activity in a disk pool gets spread over all volumes, but not too evenly.

Re: TSM DB/Disk Pool - Disk tuning question
Do sessions really lock volumes? I had always assumed they didn't. Disk volumes are random access, so for some reason I thought that several sessions could share one disk volume. In fact, I know of one site that regularly has 45-50 backup sessions running simultaneously, but only 37 disk volumes... so I'm not sure that's true. I DO believe that each new session tries to get a NEW disk volume to use; thus TSM tends to balance out the nightly backup load across its disk volumes. Maybe that's the behavior you were seeing? If that's right (Andy Raibeck? is it?), then putting 36 500MB volumes on one 18 GB disk would encourage TSM to use that one disk for all of its backup sessions - a bad thing. The more common wisdom is to make volumes that take up the entire physical disk. The only problem there is that you have less flexibility: if, in the future, you need to reapportion space between, say, your DB and a storage pool, you have to move an entire volume. I like to cut things up into 2 GB chunks; that avoids the requirement for a BFS-enabled filesystem, too. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED]]On Behalf Of Tab Trepagnier Sent: Thursday, August 30, 2001 12:26 PM To: [EMAIL PROTECTED] Subject: Re: TSM DB/Disk Pool - Disk tuning question David, My preference for disk pools is to use a lot of smaller volumes.

Re: TSM DB/Disk Pool - Disk tuning question
Lindsay, The locked volume is my understanding based on what I've observed and picked up from the list and the manuals. If that is wrong, I apologize. My set of 500 MB volumes is spread across six physical disks so I do get some load balancing. I think my system is network-bound anyway. The TSM server is on a 100 Mbs link. Running topas, I've seen the newest IBM 18 GB SCSI drives WRITE at 12 MB/s. Since almost all of my disk pool volumes are on 18Gs, I doubt that disk performace will limit the system's throughput.

Re: locate files in the tsm database
Actually, if you do a select colname, index_keyseq from syscat.columns where tabname='BACKUPS' you'll find that columns are indexed like so: NODE_NAME 1 FILESPACE_NAME2 STATE 3 TYPE 4 HL_NAME 5 LL_NAME 6 You can speed up the search significantly by specifying as many values as you can.

Re: TSM DB/Disk Pool - Disk tuning question
Locking is usually done for as little time as possible, so even if multiple sessions are sharing a volume, I don't think that's a really bad thing. Presumably TSM follows the goal of minimal locking as well. I'm guessing that by having more smaller volumes, you may be avoiding some TSM locking issues, but incurring more physical-level locking (in the OS) instead. Whenever any shared resource is used, locking must be employed. If you've got lots of small virtual volumes spread across larger physical volumes, then you may be doing less locking at the virtual volume layer, and more at the physical volume layer. Is one more efficient than the other? I have no idea. ..Paul At 11:53 AM 8/30/2001 -0500, Tab Trepagnier wrote: Lindsay, The locked volume is my understanding based on what I've observed and picked up from the list and the manuals. If that is wrong, I apologize. My set of 500 MB volumes is spread across six physical disks so I do get some load balancing.
Re: TSM DB/Disk Pool - Disk tuning question
1) there is no need to have multiple ADSM volumes, one big volume fine. One big volume means one big processing thread, which sacrifices parallelism, impairing performance. Richard Sims, BU
Re: Moving a node from a policy domain
Yes, easily. Just create the new policy domain. Then update the node(s) to specify the new domain. However, it won't cause ANY data movement. Any old data stays where it sits.

Re: backup/restore question
Paul,
Our NT admins did just that by doing an archive followed by a retrieve.
They were moving to a new machine. You could also do it with backups,
probably several ways... here are two off the top of my head:
1. Change the backup copy group to MODE=ABSOLUTE. Do your backup. Mode
absolute will cause all data to be backed up again, changed or not, so it
should all go on one tape. I did this for a disaster recovery test once.
Don't forget to change back to MODE=MODIFIED when you're done.
2. Register a new node, if you have anavailable license. Now run your
backup using -virtualnodename={the new node}. Do your restore with the
same -virtualnodename parameter. When you're all done, delete the
filespace and the node.

Hi,
We need to restore an NT machine, in testing this, it takes approximately
30
hours.
this machine has 27 gb's of data, it is the users X: drive.
is there a way to do a backup to a specific tape and then restore from
there?
we are doing this for growth and replication purposes.

Re: TSM DB/Disk Pool - Disk tuning question
The ninth sessions goes to the ninth disk volume allocated in my environment. I have not had a need to test this situation. In my environment, I would have 36 volumes if I had 8 * 9 gigs drives. An SSA disk drive can write 30 meg per second (do a move data and see) Multiple clients can write to one disk at the same time. And if you have multiple volumes, the question does not come into play. Faster than a 3590 tape drive fiber attached can receive the data also. (12-13 Meg per second) You can just watch the Brocade switch and see the different speeds exactly, though you can't forget compression in most enviroments.
