Last night 2 of our Novell clients nodes failed with a return code 12, total number of objects failed were over 3,000 from each. (see server Act log below) ... You're keeping us in suspense... You need to examine the backup log, and perhaps also the dsmerror.log, to ascertain the detail reason for the failures. The session-end stats provide no info about reasons. Richard Sims
Re: Internet favorites showing up in TSM act log

Infrastructure design questions -- I need input please
My organization is developing a DR hotsite at one of our other facilities across town, and we are considering making some radical changes to our TSM environment. I know there are several folks on this list that are heavy into TSM design and I could use all the input I can get. Our current environment consists of the following: * TSM server running 5.1.7.3 on AIX. The server is a 6-processor 6H1 w/ 8GB RAM and four 2Gb HBAs. * Approximately 350 clients, and backup 1.5 TB nightly * We use a SAN-attached 3584 with 12 LTO-1 tape drives. 60-day retention policy for everything, so we are maintaining ~90 TB in our local and offsite (copypool) tape pools. * Disk storage pools, DB, Log, are all on SAN-attached IBM Shark disk Our objective is to take advantage of the hotsite not only to improve our DR methods, but to improve TSM restore times. This is what we're considering: * Purchasing approximately 120-140 TB worth of SATA disk, which will live at our current site. All backup data will be retained on disk which should improve restore performance. * Move the tape library to the hotsite, and install a second TSM server there as well. We would no longer create two tape copies of our data, but we would create a single tape copy across town. * The two sites will be connected by dark fiber, so the speed at which we can deliver the data to the 3584 should not be a problem. Is anyone doing something similar to this? Are there any major flaws that I'm not considering? Any advice and input is appreciated. Also, I realize I need to go back and brush up on my TSM manuals, but since I don't run a two-TSM server environment, I have forgotten exactly how that will work in the kind of situation I describe. Would I only use the secondary server in the event of a disaster on the primary? Or would the secondary server at the hotsite manage the library? Etc? If someone can point me in the right direction on that aspect, I'd appreciate it. Thanks in advance, Kevin

Re: D2D vs. tape backups with TSM?
Just curious what size of file volumes are you using? We were originally using 25 GB, and then I listened to the Disk Only Backup Strategies Technical Exchange where they recommended 2-4 GB volumes. Thanks, Tim Rushforth City of Winnipeg -Original Message- From: TSM_User [mailto:[EMAIL PROTECTED] Sent: July 27, 2004 6:41 PM To: [EMAIL PROTECTED] Subject: Re: D2D vs. tape backups with TSM? Funny, we set ours down to 25% as well just to see what would happen. This worked but we have since set all of the ATA Pools to 50% and we just leave them there. Theoredically what could happen is we could be wasting twice as much space but the fact is the volumes were going from 25% to 50% in a matter of days and when we looked at how many volumes were between 25% and 50% in our enviornment we determined there was no need to reclaim down that far. From all outword signs there was no issues with reclaiming down to 25% we just didn't think it was worth doing the extra work to get back such a small amount of disk.

Re: migration from unix to windows
Yes, I have done it. There is no direct or easy way to move a TSM system from one platform to another. The data and the TSM data base are not in a compatible format between Windows AIX. If it is practical for you, the simple solution is to start clients backing up to the new Windows server, and just keep the old AIX server around until the data expires. For that to work you would need a new tape library, or need to SHARE your tape library between the two TSM servers for a while. If you want to move the data to the new Windows TSM server and you have compatible media (same type of drives in the tape library), you can EXPORT the data from the old server, and IMPORT it into the new server. For this to work, you should be sure that the new AIX TSM server is at the same level (5.1.6) as your old server. This is obviously takes a lot of time for you. If you don't have compatible media, you can set up server-to-server communications (if you have the DRM license, or TSM Extended Edition) and send the data from one server to the other. This takes even more time to do. It is a not a trivial project, no matter which way you do it.

Re: Infrastructure design questions -- I need input please
I would recommend using the second server only in the event of a disaster. Since you are connected by fibre, the primary server can send the data directly to the tape drives in the library at fibre speeds. You don't want to try and make the 2 servers talk to each other via server-to-server communications, 'cause that will just slow you down to TCP/IP speeds. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Thach, Kevin G Sent: Wednesday, July 28, 2004 9:39 AM To: [EMAIL PROTECTED] Subject: Infrastructure design questions -- I need input please My organization is developing a DR hotsite at one of our other facilities across town, and we are considering making some radical changes to our TSM environment.

Given that the systems are set up properly, the only issue you could possibly have would be bandwidth issues between the two sites. Also, I realize I need to go back and brush up on my TSM manuals, but since I don't run a two-TSM server environment, I have forgotten exactly how that will work in the kind of situation I describe.

Re: Infrastructure design questions -- I need input please
We too, are considering expanding into a site about 8 miles away... currently there are servers there that backup across the WAN (about 200GB per night) and it is not a problem. But, for DR purposes, we are considering another TSM server and library at the new location we will probably split the backup workload. In the event of a disaster, we might restore the destroyed TSM DB alongside the incumbent, and do library sharing. Kevin, one thing I'd reconsider is not having a second tape copy we have had many files become unavailable on the primary media (LTO2) for one reason or another... if not for the copy, we would have not been able to recover those files.

Re: D2D vs. tape backups with TSM?
We are using 25 GB volumes right now. We are also still collocating the storage pools that use the file device class by node. This has worked out fine for us. Sad to admit but I wasn't aware of the Technical Exchange recommendation. Is there a white paper from that you could refer me to. We are contemplating turning on node compression everywhere to also help reduce disk space. Also, I made mention in a previous post that we were reclaiming down to 50% and that was fine. Well, like always when you make a comment like that it makes you think and they you go look. I found that we were using around 16 TB's of ATA space in all when you look at the In Use numbers. When I looked at the actual disk in use it was closer to 21 TB's of data. I am currently reclaiming everything down to 40 and I plan to get down to 25 again. At that point I will compare the numbers and see how much I can reduce the 21 TB's in use. Also somewhat interesting information. We have found that the I/O capabilities of the latest and greatest servers can really help push a lot more data to disk. We have always been told by our disk vendor that the bottleneck wasn't them. We ruled out many things except them. Finally we looked at a more detailed performance monitor of our systems and we found that the we were killing the processor during times when we were pushing a lot of data to disk. With these new servers we see migrations from Fibre disk to ATA disk at over 150 GB/hr. We do have 60 TB's of ATA space though so we have a lot of disks to write to.

Re: Infrastructure design questions -- I need input please
Just a different thought why not back everything up to the a TSM server at the DR hotsite. You should easily be able to backup 1.5 TB's of information in a night though a 1 Gb connection. If this is new Fibre then you may have a 2 Gb connection or more through DWDM (or what ever that acronym is). At the DR hotsite you don't need to make storage pool copies unless you want to protect yourself from media issues. IP slowing you down, well IP definitely has more overhead than SCSI but today you should be able to get at least 250 GB/hr though a 1 Gb NIC worse case. So if your backup window is from 8:00 PM to 6:00 AM you can send 2.5 TB's of information again assuming you are just running a 1 Gb Fibre connection. So no vaulting and no need for storage pool copies. I would also put a bunch of ATA disk at the other site as well and keep all small files on disk. This will also reduce the need for tapes and drives. Your local server could be used for fail over in case the link goes down. Don't flame me, this is just another idea. I'm sure there are many people out there who can't believe I would suggest not running storage pool copies even if the primary copy is offsite but we are looking at this approach ourselves.

Re: migration from unix to windows
Depending on the network connection it is much faster to export the data and import it in one step. You don't use virtual volumes just he server to server communications. Before this all in one step using server to server was slower. Now I believe it is faster. We have migrated many nodes from one server to another as we have expanded over the years. We have found that it very easy to export nodes who have 100 - 500 GB of data in TSM. For nodes over 500 GB you may still be able to export if you have 1 Gb NIC's. If not then you may need to cut over the large servers with new full backups. We just got done migrating 800 or so nodes from 4 older Intel servers 3 new Intel Servers. The purpose wasn't just to upgrade the hardware because we could have DR'd onto the new systems for that. We were moving from an all Tape solution to a solution where all files under 3GB would stay on ATA disk. As Wanda stated though if both systems need to use the same library at the same time then you will need to set up library sharing. In our case we use STK 9310 silo's and Gresham's EDT software so all our systems can easily share the libraries. Prather, Wanda [EMAIL PROTECTED] wrote: Yes, I have done it. There is no direct or easy way to move a TSM system from one platform to another. The data and the TSM data base are not in a compatible format between Windows AIX. If it is practical for you, the simple solution is to start clients backing up to the new Windows server, and just keep the old AIX server around until the data expires. For that to work you would need a new tape library, or need to SHARE your tape library between the two TSM servers for a while. If you want to move the data to the new Windows TSM server and you have compatible media (same type of drives in the tape library), you can EXPORT the data from the old server, and IMPORT it into the new server. For this to work, you should be sure that the new AIX TSM server is at the same level (5.1.6) as your old server. This is obviously takes a lot of time for you. If you don't have compatible media, you can set up server-to-server communications (if you have the DRM license, or TSM Extended Edition) and send the data from one server to the other. This takes even more time to do. It is a not a trivial project, no matter which way you do it.

Re: Infrastructure design questions -- I need input please
Don't forget to consider the possibility that your disaster could happen the other way around - the swarms of locusts may consume your hotsite, leaving only your primary site functional. If the only copy of the data is over there, you're in the same boat, up the same creek, without the same paddle, as before you started all this DR planning. OTOH, if you aren't doing archives, and if none of the systems being backed up to TSM are at the hotsite, the offsite backup could be considered to be the original client node machines back at the primary site.

You should easily be able to backup 1.5 TB's of information in a night though a 1 Gb connection. If this is new Fibre then you may have a 2 Gb connection or more through DWDM (or what ever that acronym is). At the DR hotsite you don't need to make storage pool copies unless you want to protect yourself from media issues. IP slowing you down, well IP definitely has more overhead than SCSI but today you should be able to get at least 250 GB/hr though a 1 Gb NIC worse case. So if your backup window is from 8:00 PM to 6:00 AM you can send 2.5 TB's of information again assuming you are just running a 1 Gb Fibre connection. So no vaulting and no need for storage pool copies. I would also put a bunch of ATA disk at the other site as well and keep all small files on disk. This will also reduce the need for tapes and drives. Your local server could be used for fail over in case the link goes down. Don't flame me, this is just another idea. I'm sure there are many people out there who can't believe I would suggest not running storage pool copies even if the primary copy is offsite but we are looking at this approach ourselves. Prather, Wanda [EMAIL PROTECTED] wrote: I would recommend using the second server only in the event of a disaster. Since you are connected by fibre, the primary server can send the data directly to the tape drives in the library at fibre speeds. You don't want to try and make the 2 servers talk to each other via server-to-server communications, 'cause that will just slow you down to TCP/IP speeds. -Original Message- From: ADSM: Dist Stor Manager [mailto:[EMAIL PROTECTED] On Behalf Of Thach, Kevin G Sent: Wednesday, July 28, 2004 9:39 AM To: [EMAIL PROTECTED] Subject: Infrastructure design questions -- I need input please My organization is developing a DR hotsite at one of our other facilities across town, and we are considering making some radical changes to our TSM environment. I know there are several folks on this list that are heavy into TSM design and I could use all the input I can get. Our current environment consists of the following: * TSM server running 5.1.7.3 on AIX. The server is a 6-processor 6H1 w/ 8GB RAM and four 2Gb HBAs. * Approximately 350 clients, and backup 1.5 TB nightly * We use a SAN-attached 3584 with 12 LTO-1 tape drives. 60-day retention policy for everything, so we are maintaining ~90 TB in our local and offsite (copypool) tape pools. * Disk storage pools, DB, Log, are all on SAN-attached IBM Shark disk Our objective is to take advantage of the hotsite not only to improve our DR methods, but to improve TSM restore times. This is what we're considering: * Purchasing approximately 120-140 TB worth of SATA disk, which will live at our current site. All backup data will be retained on disk which should improve restore performance. * Move the tape library to the hotsite, and install a second TSM server there as well. We would no longer create two tape copies of our data, but we would create a single tape copy across town. * The two sites will be connected by dark fiber, so the speed at which we can deliver the data to the 3584 should not be a problem. Is anyone doing something similar to this? Are there any major flaws that I'm not considering? Any advice and input is appreciated. Also, I realize I need to go back and brush up on my TSM manuals, but since I don't run a two-TSM server environment, I have forgotten exactly how that will work in the kind of situation I describe. Would I only use the secondary server in the event of a disaster on the primary? Or would the secondary server at the hotsite manage the library? Etc? If someone can point me in the right direction on that aspect, I'd appreciate it. Thanks in advance, Kevin - Do you Yahoo!? Yahoo! Mail - 50x more storage than other providers!
