Re: TSM performance very poor, Recovery log is being pinned
Thanks for all input guys, Firstly sorry for lack of detail. TSM is installed on Solaris 10, No I did not do any benchmarking, as we were not replacing any existing setup just adding more, I have 6 LTO drives already installed and about 17TB of SAN storage which is Primary Random, I have since added 4 new LTO 3 drives (with different Device classes) and they run better than the LTO 1 drives, when server is not logpinning. And the new 15 TB of SATA, now approx 1 TB of the DISK is Primary Random storage and the remainder is SEQ file and its all FS not RAW, I have had heavy discussion over RAW vs FS and I have not been able to find definitive answer Clients I don;t think are causing the issue any TSM processes can pin the log from migrations DB backups and clients sessions. Once the server starts getting busy. Currently (sorry not in front of installation) but I guess of the 15TB I have about 60 sequential volumes across 4 Stgpools, and I have still more to define. I have not had clients utilize this new storage yet, all I have done is start to migrate data into these STGPools to release some of the legacy STGpools The Transport to DB and Recovery Log is SAN, however yesterday I created local copy and this did not improve things. The STGpools are on WMS SAN and AMS500 SAN. Both SATA disk. All across Fibre!! The SAN engineer when installing the Disk's saw expected performance out of the DISK's. I also don't see it being maxsessions because I can Pin the log with 3 or 4 sessions and 3 processes! I think its safe to say its configuration somewhere, because now I think about it its not taking much load to pin the log. Load in which TSM normally copes ok!! Next step may be to remove the New DISK's now will I need to just unmount the FS or will i Need to migrate data off new storage and delete volumes and New STGpools?

John, In your comparison, you may want to include option #3 - tar (unix) and backup (Windows).

Re: TSM vs. Legato Networker Comparison
Stuart, Thanks for your excellent point. One thing that frequently determines the reputation of a backup product within a company is the quality of the hardware it is running on, and the skillset of the people managing it. We had one remote location with an old LTO1 tape library, running TSM 5.1 on a 700MHz Pentium II Win2K box with a 10/100 card, and the people supporting it hated TSM because "this TSM server is always having problems". We have since upgraded it to a new IBM LTO3 library and a CDL 210, running TSM 5.3.4.2 on a new Win2003 server with dual 3.2Ghz Xeons w/GigE, and all the problems have gone away. Now the people who monitor it have nothing to complain about, so they complain about our Exchange servers instead! Time to upgrade those next, I guess. Best Regards, John D.

Monash was a Legato (now owned by EMC) shop until the TSM migration around 3-4 years ago; I suspect that a large number of the problems that were perceived to be Networker's fault were actually the fault of the aging DLT silos and drives that underlay Networker. I still have fond memories of those silos; they gave me a great deal of callout pay every time they had a stuck cartridge or similar. :-) I also suspect that the greater reliability we've had since putting in TSM is more because we also got in new tape silos (LTO2, now half LTO2 and half LTO3, and soon to be half LTO3 and half LTO4) - if we'd stuck with the DLT silos, we'd still be in a world of pain, regardless of the software. There are plusses and minuses to both products. Some points to consider: * Networker uses the traditional "full plus incrementals, or dump levels" system. Monash used a pattern of "full once a month; incremental every other day; and a dump level interwoven" - so, for example, it might go "full, incremental, level 8, incremental, level 7, incremental, level 9, level 2, incremental, level 8, incremental, etc." - the idea being to minimise the number of backups needed to restore a system. * Networker indexes are somewhat analogous to the TSM database. In theory, you can scan each tape to rebuild the indexes if they're lost; in practice, if you lose the indexes, you're pretty much dead - there's just too much data to scan if the system is more than moderately sized. Yes, Networker backs up the indexes each day. :) * At least the versions of Networker (up to 7.x) we used doesn't support the idea of staging to disk - everything goes directly to tape. However, data streams from multiple clients are multiplexed onto tape to get the write speeds up. This is good for backups, but does make recovery slower (since the data read will include a lot of data for other clients.) * No more reclamation or copy pools to deal with (because of the traditional full/incremental/dump level system). So the burden placed on the tape drives is probably going to be significantly lower (although you will be backing up more data each night than you would with TSM.) * I don't think Networker has anything analogous to TSM's scratch pool: volumes belong to a pool of tapes, and there's no shuffling between the pool. So if the "standard" pool has a hundred tapes available for use, but the "database" pool is out of tapes and needs one more, you need to manually intervene. This *may* have been because of the way we configured Networker, though, and it may also have changed in the interim. Note that you *have* to have a separate pool of tapes for index backups. My honest assessment mirrors that of the other people who have replied: use this as an opportunity to negotiate better pricing from IBM, and point out to the powers that be that there are risks involved with moving to a different backup product. There's nothing wrong with Networker, it's a good syste

Re: New policy domain
It depends of the name of management class in the new domain. For backup copy groups, if TSM find a mgmt class with the same name in the new domain (and with a backup copy group within...), it will rebind objects to the new policies If not, it will rebind object to the default mgmt class I think it's the same for archive copy groups but check that to be sure...

Hi everyone, I have a few quick question regarding changing policy domains. I looked through the admin guide but it didn't clear all my questions up. We are still running 5.2 (soon to be 5.3). We need to change a few clients to start using a completely new policy domain which includes a new storage pool and retention periods.. etc etc. Once we change the clients policy domain what exactly happens to the existing data in the old policy domain?

Sorry for the confusion here all. I have sent out a reponse to this post earlier this AM, but it is taking a while to post. Looks like you responded to it below. I am not sure why this is not included in the post. I will try posting it again. FYI, the file system is a large file enabled JFS2 and filesize is set to unlimited. I created a file larger than 64Gb with AIX on the filesystem with no problems. IBM says this is a TSM limitation not an AIX one and they have an APAR associated with it (see link below) --- Again im sorry, this was my mistake, I miss understood what my colleague had told me. Indeed AIX its self will work with file spaces larger than 64g BUT As per the APAR I linked you... http://www-1.ibm.com/support/docview.wss?uid=swg1IC50581 The 64g is a known limitation of TSM on AIX systems.

An old gotcha on AIX was the ulimits file. Limiting the filesize any user could create. Also if the filesystem was large file enabled for files over 2 GB. These are quite old issues though.

Re: TSM performance very poor, Recovery log is being pinned
You might also check your diskpool volume count. If its low, assuming your doing raw logical volumes, you might want to try decreasing the size of your volumes and thereby increasing the count of your volumes . A small number of large volumes does not allow several clients or processes to stream data to the storage pools efficiently. Joy Hanna Enterprise Storage Group I.T.

Re: 6 vs 8 character LTO2 volser - do I care ?
Thanks for the tip. Since I really needed to get moving on this, I am simply letting the new Library Manager server reinitialize the tapes as 8-chars as needed. This way I will recreate the offsite pool, fresh, and avoid the long list of reclaims that are constantly waiting due to lack of drives/time.

Re: Sharing a 3583 library
No, that is not what I meant. I realize I will eventually need to reconfigure all of the TSM servers. I just wanted to reconfigure in an optimal way or was hoping to not have to drag drives from one library manager to another and possibly back and forth, if needed. As I mentioned, I was hoping for some "smart" sharing of devices since TSM does manage the drive usage. As for the 6/8 volsers, I am just letting the new LM server reinitialize the tapes as 8-chars.

So if I understand you correctly, you will eventually be moving the library management completely to the new server, but you want to avoid reconfiguring all the existing TSM instances? I've just completed moving two library managers from one TSM instance to another (the "new" manager is dedicated solely to library and configuration management, where the "old" managers also served backup duties.) It turned out to be remarkably easy: * Delete the old paths, drive definitions and library definition on the old library manager (and the new library manager if it's currently a library client). * Define the library, drives, and paths on the new library manager (setting the drives to offline, so no tapes are accessed until you're finished.) * Checkin the libvols on the new library manager (CHECKIN LIBVOL X search=yes stat=scratch checkl=barcode) * Update the old library clients (UPDATE LIBRARY X PRIM=new_lib_manager on all instances) * Create a library definition on the old library managed (of type shared, pointing at the new library manager.) * Run an AUDIT LIBRARY on the library clients (including the old library manager). * Set the drives to online, and you're away. The audit on each client will set tapes with data to private status, owned by the relevant client. If you're paranoid about this, check them in as private, owned by the new library manager, and make a note of the scratch volumes known by the old library manager before deleting the library definition (query libvol). The audit will update the ownership to the correct node, you can manually update the remaining volumes to be scratch, and chase up the remaining volumes owned by the new library manager (assuming it didn't own any volumes beforehand) as potentially orphaned - we found some 30 tapes that should have been returned to scratch by the clients, but the library manager hadn't updated them for some reason so they were still marked as being private. As for the 6/8 character volume label: I can't speak for a 3583, but we're using a pair of 3584 libraries. In the web-based management system, there's a section for "Library", "Logical Libraries"; have a look at the "modify volser reporting" option - it might help. Note that this will likely affect *all* volumes, so if you have data stored on volumes with a mix of 8/6 volume serial numbers, you're in trouble ... Hope this helps.

Re: 6 vs 8 character LTO2 volser - do I care ?
You can adjust the volser reporting on the Library, which is the safer way to control volser reporting. On the main menu => more => Setup => Library => MEDIA The you choose the volser reporting 8 char or 6 char. After that, you will never bother with volser mode, and you don't have to manage it through special files of your OS Then you will have to re label all that tapes originally labeled with 8 char labels. I hope some are not already used...

TDP for Exchange - poor performance during online backup
I'm running Exchange Version 6.5.7638.1 under W2k3 Sever with TDP for Exchange 5.3.3. Running an online backup it starts with a data rate of aprx. 10 MB/sec. After some minutes this rate slows down to aprx. 1 MB/sec. The effect of this is, that a backup of aprx. 90 GB of data will last aprx. 30 hours. Does any body have an idea what's the reason for that strange behavior. Thanks Ron
Re: TSM performance very poor, Recovery log is being pinned
Craig - You need to perform analysis to identify problem cause, where the TSM Problem Determination Guide and Performance Tuning Guide will help. Log pinning is due to prolonged transactions, and is aggravated by sluggish networking and sluggish TSM servicing of transactions (often due to underlying disk/tape issues). You can quickly see if your TSM server is "behind" in its rate of servicing incoming client data by inspecting the TCP receive queue packets backlog. In AIX that can be done via the command: netstat | head -2 ; netstat | grep -vi dns | grep tcp If the various entries show a large receive queue value, then it is likely that your networking is good, but that TSM is not keeping up with the incoming, as may be caused by the underlying disk, tape, and I/O path technology that it is using. If your clients have recently started backing up very large files (digital movies is a stereotypical case), then that would certainly contribute to what you're seeing. A quick look at TSM accounting data or ANE Activity Log messages would give a sense of that, and Query CONTent with a negative Count value on the collocated tape volumes that the clients are doing will show biggies. Query SESSion during client activity will also help identify consumptive sessions. Before you gave TSM the new LTO 3 and SATA hardware, I would hope that you benchmarked it first, to assure that it was providing the performance you would need in production, and thus uncover any issues with it beforehand. A bad RAID choice in disk implementation will also slow throughput. Old microcode may have performance-impairing defects. A mismatched device driver can cause operational delays. Don't waste your time or jeopardize your server in doing a TSM db unload/reload. You may want to confer with your operating system people to have them help narrow down the problem area, where they are familiar with all the specifics of your environment. Richard Sims
TSM performance very poor, Recovery log is being pinned
10 days ago I Recently added 15TB of SATA storage and a new Fabric with 4 new LTO drives to our 3584 library, The DB is approx 90GB TSM Few days ago I noticed processing had ground to halt, after digging around I have found as soon as server gets busy maybe 4 processes 8 or so sessions the recovery log begins "sh logpinned" to pin and the Database gets locks. Shown by running "sh locks" And as result the server suffers! Now today I have stopped using the new Tech LTO 3 and SATA and things are coping better but still worse than previous as soon as load is increased Log pins and processing slows drastically. Are there any steps I can take which will help my scenario. Would a DB UNLOAD RELOAD help that much? Reference: Recovery log has heaps of room DB has heaps of room 90Gb DB with 100GB of room. Any advice is much appreciated.
