Re: How to save volhist and devconfig
Hi, I have had good experience in creating a TSM Administrative Schedule that saves volhist and devcnfg to disk. Then I've made a client schedule that sends a mail with those files (and different status messages for TSM) to backupoperators (including an external account, in case of a complete disaster - mailserver and TSM server are in the same location).

How to backup a shared disk array?
We have a storage array fronted by two, clustered NT servers. The NT servers are identically (or nearly identically) configured. Each has a TSM client installed. We'd like to develop a TSM backup stategy that permits daily incremental backup of both servers, including the storage array, but without doubly backing up the storage array. If either server fails, the other server should be able to *automatically* assume the role of backing up the storage array. Either server should be able to restore storage array files. Any suggestions? Bob Brazner Johnson Controls, Inc. (414) 524-2570

Striped backup speeds.
Environment Server: TSM 4.2.1.7, AIX 4.3.3, two fiber gigabit ethernet cards, each accessing disk and tape (I know, this is bad, but it shouldn't impact this situation) Client: W2K, 4 processors (around 900mhz, I think), just over 3GB of physical memory, TSM B/A client 4.2.1.32, TSPSQL 2.2, Storage agent 4.2.1.7, three fiber gigabit ethernet cards (qLogic), one for disk, two for tape access. SAN: Shark ESS Node setup has 4 mountpoints allowed. Fiber Network: dual Brocade 2109 fiber switches. Library IBM 3584 with five LTO Ultrium fiber connected drives (three connected to one switch, two to the other switch). Utility used to measure speed during backups: qLogic Sanblade Manager. Backing up a 33GB SQL database located on the Shark to one tape, I can get about 28-30 MB/second. Backing up the same database striped to two tapes, I would get about 31 MB/second. I had the DB admin spread the three files in the database over three of the four different available drive letters (actually on 2 different packs on the ESS Shark). That made my two-stripe backup in the 36-37MB/second range (single stripe backups are still in the 28-30MB/second range). I am looking to find a way to get somewhere near the 50-60MB/s range for a backup. It doesn't make sense to stripe a backup when you are only getting a 20% increase in throughput (and this works out to less than a 20% decrease in time for the backup because of the storage agent mounting tapes, locating last files, etc, one tape at a time). I am doing testing in preparation for a 500GB database. I did some tests with very large files on each of the four drive letters, simultaneously copying the large files to >nul (using four different command line prompts), to get a benchmark of data throughput on the disk fiber card. The max sustained throughput (based on the qLogic monitor) was ~66MB/second. Most of the time, the rate hovered in the 45-55 MB/second range. CPU utilization on the client node during a 2-stripe backup is around 85-95%, and during a single-stripe backup, it is around 35-45% (on all four processors). Can anyone suggest some things to check that might impact this? On another note, the backups are not completing as of my last two-stripe test. I am working with Tivoli support regarding this problem. Backups with a single stripe are working.

Re: How to save volhist and devconfig
I have written a batch file that runs on our operators' Win2k Pro machine. The batch file maps the network drive to the TSM server and copies the required files to local diskette and another network drive.

Re: question on configuring large NT client for optimum restore p roce ssing
This isn't a Netappliance NAS -- this is two IBM netfinity boxes running Win2K server with TSM 4.2 client installed, running as an MS cluster, with fiber-attached FastT disk. So I don't have the double load issue. I'm pushing the NT staff for the multiple drive letter option, but current planning is that IF we *have* to do multple drives then this 800K files will be one of the drives. The NT group would rather set the entore 1.2 TB up as one drive . . . One of my thoughts was to assign several management classes with the inlude-exclude list, then define the copygroups as co-located but use the same storage pools. Has anyone out there tried this stunt? I mean, the example for multiple restores for NT shows c:\users, c:\data1, and c:\data2 and then later states that 'if data2 is on a different tape' -- so I'm trying to force the issue.

Réf. : Re: Backup of Win2`K Fileserver
Hi Thanks for the tips. I backup 150 other clients (mostly NT but with some AIX and TDP's) with not much performance problems. The server is AIX. The database is on a Hitachi 7700E (15 GB 1rpm disks - RAID5) with dual path fiberchannel. I'm thinking its the compaq san thats the problem. My group didn't have any say on how it was configured. I did an FTP yesterday (used the dsmsched.log which is now 100 Megs...) and it was very slow so the culprit is probably client side. The 2 ethernet (100 mbs) cards on my server are used at max (12mbytes/sec) each when we do TDP Notes backups so they're working OK. There is a Token-Ring card on the server so the backup is probably going through there. I'll check with the sysadmins if the cpu is is used over 50% . If so I'l turn off compression.

Re: Backup of Win2`K Fileserver
Guillaume, Set the serialization in the copypool to dynamic and changingretries to 0. Your txnbytelimit allows transaction as large as 250 meg; you don't want to let anything cause a termination and rollback of such a large transaction which is why, I assume, you have compressalways = yes. On subsequent incremental backups you can use a different serialization. Hope this helps, Bill At 04:30 PM 7/31/2002, you wrote: >Hello > >I have a BIG performance problem with the backup of a win2k fileserver. It used to be >pretty long before but it was managable.

Re: Offsite Archives & DRM
Gordon, DRM will not vault primary pool or backupset media. An alternative product, AutoVault, has primary pool and backupset vaulting for precisely what you are trying to accomplish. For specific situations, it is a very efficient way to retain data long-term without the need to duplicate the data or fill your tape library. The one risk is that you will not have a second copy of the data to recover from media failure. Using AutoVault, you would direct your archive data to a separate primary pool hierarchy. It sounds like all your TSM data is archives, so you may not have a need for an incremental backup primary pool hierarchy and a copypool. Configure AutoVault to vault your archive tape primary pool. It will eject the media from your library and generate a report of what media to take offsite. It will also generate a report of empty tapes to return from the vault. Many of our customers are effectively using this technique for archive data, backupsets, and TDP (database backup) data.

The concept of a copy pool is to be able to protect the data in two locations. And DRM is the vehicle to support that. What you really are trying to do is a archive using primary copy pool tapes which is not what TSM was designed to do. As I see it you only have one choice here. You will have to roll your own tape movement thing. With primary tapes you have to mark them to unavailable using an UPDATE VOLUME vv ACCESS=UNAVAILABLE. You can probably create a SELECT statement that meets your criteria to create the command as follows: Select 'UPDATE VOLUME ', volume_name, 'ACCESS=UNAVAILABLE' from volumes where stgpool_name='TAPEARCH' and volume_name in (select volume_name from libvolumes) > /mark.cmd This gives you all the tapes in your library that are in the storage pool. Run this output as a macro command after striping off the first 2 lines. Then do another select: Select 'CHECKOUT LIBVOLUME ', library_name, volume_name, 'other appropriate parameters' from libvolumes where volume_name in (select volume_name from volumes where access='UNAVAILABLE') > /eject.cmd Run this the same way as above. At this point the tapes should be checked out of your library and TSM should not try to do anything with them. Now, I have not tried this so you will have to do some significant testing. There may be something I did not consider. The real negative piece here is you have to manage what expires and is ready to be put back in the library. Paul D.

I've been reading the TSM Admin Guide today about DRM and copy storage pools and I think have found the solution to ours problems, however I would like to run it by some more knowledgable people. First I'll give a quick overview how our archives are currently working, I should also mention that these are really 'snapshots' of existing data on our servers and not actually removing any data from their locations. Once a month we have a scheduled job execute on our Tivoli server which runs the command "dsmc archiveetc" on each of our servers. As the server backs up the data to the Tivoli server it is temporarily stored in a disk storage pool (ARCHIVE) on our SAN, then as this disk storage pool fills up the data starts to automatically migrate across to another storage pool of type sequential access (called TAPEARCH). The next morning a scheduled job runs which migrates the remaining data held within the disk storage pool
Space reclamation of copypool
Hello everyone, I have the following problem with Space Reclamation of my copypool. To start reclamation I have a script running UPDATE STG COPYPOOL RECLAIM=50 Three hours later, I run another script to stop reclamation - UPDATE STG COPYPOOL RECLAIM=100 but reclamation never stops. This affects all of my daily operations (migration, backup stgp..) because the reclamation process uses both drives. Question is, why does space reclamation not stop after updating? Is there a way of canceling the process (by TSM script)? Best regards Geirr G. Halvorsen

Re: question on configuring large NT client for optimum restore p roce ssing
First thing is NAS puts double load on the network. If you have the NAS box on a different interface with Gigabit connectivity that would help. Also Gigabit to your TSM server. Divide the data up into as many drive letters (filesystems) as you can so that you can run simultaneous backups/restores as multiple threads. Setup the Resourceutlization has high as you can tolerate. You really needed to go for SAN on this. The IP stack overhead for CIFS is very high which is how the NAS box communicates with the NT server. There may be some other options to use the NDMP capabilities of TSM check into that. It may do what you want and improve performance dramatically. Especially, if the NAS box has SAN connectivity capabilities for backup and recovery. Paul D.

One advantage to the MSCS is that disk compression is not allowed, so that should speed things up a bit on the restore. Tom Kauffman NIBCO, Inc

Hi, Configure as many filespaces (driveletters) as you can get. Thus creating a nice way for multiple (manual) restore sessions. Configure multiple storagepools and spread the back-up data over them. If you use LTO drive, we do, don't use collogation (my experience), but make sure that the date is on not to many tapes (depents number of tapedrives, mounttimes, sort drive). Also keep the performance of the TSM server at a high level (processing power, memory). Gr.
