Re: Mount Wait with LTO drives
We have a 3584 Library with for LTO SCSI drives connected to the SAN using a Gateway. When we backup a SQl database, we seem the tape mount within 20 seconds, but it then seems to take 2 -3 minutes before the data is streamed straight to the tape. We are using LAN free backup. Anybody any idea why it takes so long to start sending data to the tape? You didn't specify whether this was a scratch tape or one that was Filling, but probably the latter, in which positioning has to occur. You can check this by watching the drive's display: it will show Tape Loading... followed by Locating... (It takes 3590s a while to position, too.) Your level of microcode can influence how long the positioning takes, with transport speed being the limiting factor. Richard Sims, BU

Sun client error
Hi *SM-ers! One of my Sun TSM clients reports error 195 during backups. This seems to be related to APAR IC26775: CLIENT BACKUPS FAIL WITH RETURN CODE 195 I have downloaded IC26775.tar.Z and installed the 3.7.2.14 client which is supposed to fix this problem, but I still see the error. The strange thing is that I can see in the Sun installation logs that IC26775 has been installed, but when I start DSMC it still reports level 3.7.2. Now I'm confused. Shouldn't it report 3.7.2.14 or is the version number not updated in this new code? I hope somebody can shed some light on this. Thanks in advance for any reply!!!

Re: How to migrate TSM from OS/390 onto AIX
We used server to server to export the nodes to an AIX TSM server. We had a 20gig database with several hundred nodes that we migrated. We did the migration a node at a time over a 4 month period. We would lock the node, do the export, then import on the AIX server, add the node to a schedule, and then notify the customer that he needed to change the ip address for the TSM server. You need a lot of patience because if you get an error there is no way to restart the export where you left off. For some of our larger nodes we ended up exporting them a filespace or several filespaces at a time.

Delete Archive.
Hello everyone, We are running TSM 3.7.4 on OS/390 2.10 and I have a RS/6000 AIX 4.3 and the TSM 3.7.2 client and I have a question on the Delete Archive command. I have a UNIX client and the administrator of this node has been doing some cleanup of the Archive data for this node by issuing the Delete Archive command from the clients command line. I did check the client access to ensure that they had the ability to delete archives and that parameter is set correctly and I can see sessions active for the node when the administrator is running the deletes. I do not see any processes active when the deletes are running from the TSM server. According to the administrator there were several thousand files deleted from this node but when I issue the Q OCC command for the node the number of files has not changed since before the deletes were run. I also expected to see our data base percentage decrease. We did run expiration after the Delete Archive command had completed but no decrease in any of the items mentioned earlier has occurred.

Brian - You didn't say whether the final ANR0812I message from the Expire Inventory reported that archive files were deleted. Run the Expire Inventory with Quiet=No to assure that it visits the filespace that your client supposedly deleted files from. And run it without a limiting Duration value so that it doesn't stop prematurely. Try to get from the client a log of the deletions to assure that they actually occurred. Unfortunately, TSM doesn't let us SQL-query the flagging involved in archive files so that we can see if they have been marked for deletion. (In the Archives table, they look the same before and after Delete Archive.) And, in all this, we presume that your client means files that were archived with the standard client, as only those are treated by Expire Inventory: files sent to the server via some API (which your client may loosely term as archiving) have to expired via the API.

Re: TDP for MS SQL cross server restore
Joel, From the TDP for SQL 2.2 README file... Backups made with TDP for MS SQL Version 1 CANNOT be queried or restored using Version 2 nor can backups made with Version 2 be queried or restored using Version 1. You must keep TDP for MS SQL Version 1 for as long as you have Version 1 backups that may need to be restored. There is a longer explanation on why in the User's Guide. Look at a section titled: Version Migration/Coexistence Considerations OK. So what can you do? Install version 1 on Host-B (both V1 and V2 will coexist nicely) and restore your database.

Backup a BIG Sap installation
We have a potential client that wants to backup a 1.2TB SAP database in a 3-hour window. Currently they are using Omniback and an HP SureStore library with 10 LTO drives SCSI attached. If we were to repace Omniback with a TSM server on the SAP server, using those same LTO drives and TDP for SAP, would this be possible? I'm looking for some real world opinions. Right now I think they stop SAP and backup the database files. I do not believe they are using SAPDBA. Thanks, Bill Boyer He who laughs last... probably did a backup! - ???
Re: TSM 3.7.2 client
Jeff, You can check the Tivoli web site (www.tivoli.com) and look at the client requirements to determine which OS's are supported at which client versions. The direct page is http://www.tivoli.com/support/storage_mgr/clients.html. When we announce new products, the announcement includes the client platforms supported by that product. Aside from that, I really do not know what other mechanisms our Marketing team has to get the word out.

Re: Backup a BIG Sap installation

We will be implementing TDP for SAP on production soon we are currently running it only in development. I would suspect it would be possible but I am not sure with just 10 drives.

Re: Backup a BIG Sap installation
Bill, what are the SAP and TSM platforms? I'm doing a 540 GB SAP database in 3.0 hours to 5 DLT-7000 drives. My bottleneck is the drives - I'm averaging 9 MB/sec per drive (45 MB/sec over the 3 hour window). We're planning on LTO drives in the 3rd quarter and I expect to move the bottleneck to the network. I'm on an 4 GB S7A (RS/6000) with 8 CPUs and 3 fiber-channel attachments to an ESS for the SAP database server, and a 4 GB S7A with 4 CPUs as the TSM server. My tape drives are SCSI, two to an adapter card, and I have two independant gigabit ethernet networks between the systems. I run three sessions on one network and two on the other -- we use backint to interface between SAP/Oracle and TSM on the SAP DB box. One thing I've found is that I get better throughput with TSM on a seperate box. Our TSM server is the SAP DB fallover box, and when both environments are running on the same system all the IP traffic gets run through the loopback interface. Short answer -- should fit with no real problem given the number of tape drives available. Long answer -- If TSM and SAP servers both live on the same box, you'll get the backups into the window, but on-line backups will probably busy things out so much that they might as well be off-line backups.

Re: Backup a BIG Sap installation
Tom, Excellent description! I find your assertion that using two different boxes and the network is faster than both apps on the same box.

Re: Backup a BIG Sap installation
Hallo, we backup nearly twenty SAP DBs with TSM 4.1 and SQL Backtrack from BMC. Our biggest DB is now around 450 GB. We use 3590 drives (FC connected to a SUN E450). The network interface is a dedicated switched gigabit ethernet for all SAP DB server. Our experiences are: With two streams and SQL BT compression we backup 450 GB in 2 hours 20 minutes. Due to the lack of more drives we cannot use four streams in production, which would use all the network bandwith we have and reduce the backup time to a bit more than 1 hour. Compression rate is nearly 70 % (SAP DBs have a lot of unused space in it). We saw transmission rates of nearly 35 MB/s (so 100% drive speed).

IBM 3600-109/220/R20 LTO with TSM
Hi all, does anybody some experience with these devices in TSM?: 1. 3600-109 LTO Autoloader 2. 3600-220 (R20) LTO Tape Library The first one is 9-slot LTO Autoloader (i mean equivalent to IBM 3581 7-slot Autoloader), second one is LTO Tape Library (1-2 drives, 20 slots no more scalable). In TSM device support list are not listed these devices, but I'd like to get some references, if somebody tried them to use with TSM.
