Re: backup nasnode questions
Hi Markus, thanks for your reply. - the full backup will be kept until the next one is performed, but it will no longer be reported on with the query, so don´t worry if it doesn´t seem to show up... you can´t prove it is still there apart from performing a restore: hard to believe, I admit, but it just works that way So knock on wood if you need a restore and the full backup is still there ;-) - the summary table reports processes on volumes but utterly fails to report on virtual filespacemappings regarding these processes, making it useless for reporting and analysis I don't use vfsmappings at the moment. Finding the right frequency regarding full/differential is a pain, we have come up with a 4-week rotation using virtual filespace-mappings which works quite well as only approximately a quarter of the data goes through a full per weekend. So we end up with one admin schedule and script for Monday through Wednesday doing differentials plus four for the four fridays doing partial fulls. I wrote a single script that I call with different values for the input variables, like the following example: backup node netapp /vol/vol0 mode=$1 mgmt=netapp backup node netapp /vol/vol1 mode=$2 mgmt=netapp backup node netapp /vol/vol2 mode=$3 mgmt=netapp backup node netapp /vol/vol3 mode=$4 mgmt=netapp On weekdays I call the script with the arguments diff diff diff diff, on every second Saturday with full diff diff diff or diff full diff diff and on every second Sunday with diff diff full diff or diff diff diff full. So I have full backups every two weeks for each volume. It works, but I think, TSM should come up with a better solution. -- Regards, Dirk Kastens Universitaet Osnabrueck, Rechenzentrum (Computer Center) Albrechtstr. 28, 49069 Osnabrueck, Germany Tel.: +49-541-969-2347, FAX: -2470

backup nasnode questions
Hi, I just configured our TSM server (5.4.1.2 on AIX) to backup our two NetApp filers. I have a few question regarding the NDMP backups: - How do I have to define the backup copygroup? I want to keep the full backup and two differentials. Is it correct to set the option verexists=2? After the third backup I only see the two differentials with the command q nasbackup. The full backup disappeared because it seems to have been expired. - How long will the full backup be kept? - Is it possible to get some information about the last full backup after it has been expired? - Is it possible to automatically create full backups after a given time (2 weeks for example)? It's not a good idea to create full backups of the whole filers on the same day, so I want to define a different time for each filesystem. Is it possible without defining separate schedules for each filesystem? It would be nice to have an option for a filesystem that says create a full backup every 14 days. - I don't see accounting information about the nas backups in the dsmaccnt.log file. Is it possible to find out how much data has been backed up from the nas nodes? Sorry for so many questions but the TSM manuals are a bit rare on this topic. -- Viele Gruesse, Dirk Kastens Universitaet Osnabrueck, Rechenzentrum (Computer Center) Albrechtstr. 28, 49069 Osnabrueck, Germany Tel.: +49-541-969-2347, FAX: -2470
Re: backup nasnode questions
Larry, thanks for your reply, but: Per the TSM 5.4 Admin reference: If you backup up at an attached library you need to create a copypool with the same NDMP data format...in your case NETAPPDUMP. In other situations, the format needs to be NATIVE. I backup directly to the TSM server. There is no library or drive attached to the filers. verexists refers to active copies. What is your retain extra set for? The full may still exist as an inactive file. If you want a full and two incrementals active you'll have to change your verexists value. Do a query with inact=yes to see if the full is still available for restore. The q nasbackup command doesn't have an inactive option. When I set the verexists=2 option, after the first backup, the full image is the active version. After the second backup, the full image changes to inactive and the differential is the active version. After the third backup, the first differential changes to inactive and the second differential is active. The full backup has disappeared from the list, although it must be there because the differential depends on the full backup. I don't see a command that can list the expired full backup. On the other hand, I don't want to keep 14 differential backups until I make the next full backup. I just want to keep (and see) the full backup and the last two differentials. Scheduling full backups every two weeks: Use a separate schedule for full backups with a perunits=weeks period=2 Yes, but I don't want to backup the whole filer once every two weeks. I want to backup vol1 on Monday, vol2 on Tuesday, and so on, what means, that I had to define a single schedule for each filesystem. My idea was to set an options on a filespace that automatically arranges a full backup after a defined number of days. So I only need one schedule with the backup node command, TSM looks up the date of the last full backup of each filesystem and handles the next full backup dependent on the defined option. -- Regards, Dirk Kastens Universitaet Osnabrueck, Rechenzentrum (Computer Center) Albrechtstr. 28, 49069 Osnabrueck, Germany Tel.: +49-541-969-2347, FAX: -2470

Sounds fun doesn't it? Obviously their way of getting you for have CPU's with multiple cores. I never understood why a backup software is being licensed based on the number or type of the processors. This would be ok for a database or mathematical software but not for a backup software. TSM will backup the same data, be it on a single or multi processor machine. I also don't understand why a client running on a server is more expensive than a client running on a workstation. Both are TSM clients, doing the same job. The old licensing scheme, where you have to pay much for the TSM server and less for any client was much more accurate in my opinion.

Re: Client restores for NFS server backups
Hi, Richard Sims schrieb: In TSM 5.3, the Virtualnodename mechanism has further evolved into a Proxy Node capability, described in the 5.3 Admin Guide, client manual, and the TSM 5.3 Technical Guide.

I don't have experience with this, but it would be interesting to hear from any sites which have pursued it. I think, there's a big security issue. I just granted proxy authority to one of our NFS clients. The backups are made on TSM node nfsserver and the node nfsclient acts as a proxynode. So I added the following lines to the dsm.sys on the client node: nodename nfsclient asnodename nfsserver But now, when I log on to the NFS client as a normal user, I am able to restore arbitrary files of other users to my home directory The other homedirectories are not readable for me, so an ls /home/myboss doesn't work. But using dsmc I get access to all files of all other users. With dsmc q ba -subd=y /home/myboss/ I get a list of all files of my boss.

Linux GUI and client user id

There wasn't any problem with that, until I started the java gui on a linux client (v5.3.2.0). The gui presents a login window with a field for the user id (which is the same as the nodename) and for the password. When I enter the password, I always get the error message ANS1370E The user ID entered does not have the correct level of authority to access the client machine. No work can be done with the client gui. When I create an admin on the server and assign authority for the client node to it, the client gui works.

linux dsmcad problem
Hi, TSM 5.3.2.3 server TSM 5.3.2.0 client on redhat linux I start the dsmcad process with the rc.d script from the technote. The problem is that the schedule only works once. After the backup is finished the client scheduler stops but never gets called again, although the dsmcad process is still running. During the next backup period the tsm server says that the session with the client timed out. The last entry in the dsmsched.log is: 03/07/2006 00:52:31 Scheduler has been stopped. The last entry in the dsmwebcl.log is: 03/07/2006 00:52:32 (dsmcad) Waiting to be contacted by the server. But nothing happens.

Re: Database restore and mirrored volume question
Hi, volumes. If so, I think you have to do the restore prior to setting up the mirrored copies, since the syntax for 'dsmserv format' has no provision for specifying mirrored volumes. I recently had to restore our database. It has mirrored volumes, but the restore was written to the first copy. After completion TSM synchronized the copies, what took another hour or so. -- Regards, Dirk Kastens Universitaet Osnabrueck, Rechenzentrum (Computer Center) Albrechtstr. 28, 49069 Osnabrueck, Germany Tel.: +49-541-969-2347, FAX: -2470
Re: DB LOG Volume layout - new
Hi, Tab Trepagnier schrieb: The bottom line is that I/O Wait time was cut in half. While expiration still takes approximately the same time as on the old setup, the reduction in I/O Wait time means the server has more cycles for other work. So even with a heavy workload, the server still provides very fast response time and can manage dozens of client sessions while doing expiration and reclamation at the same time. That's interesting. I just made some tests on our new server. At first I defined three big dbvolumes (using raw logical volumes), each on a separate hdisk (AIX 5.3), and each being mirrored by TSM on another hdisk. When TSM started up, or when I did an auditdb, only one of the primary volumes was active at a time, with a read throughput of about 1000 kB/s (measured with topas). Then I defined striped logical volumes using three hdisks. During startup or an auditdb all three disks were active at a time, but the read throughput of each disk was degraded to 250 kB/s, what makes 750 kB/s for the whole volume. That means that the throughput was higher with separated volumes. Or did I make a mistake? Regards, Dirk Kastens

Hi, Allen S. Rout schrieb: Paul's got it. Even with a non-new server, take a look at Q DBVOL f=d. It'll be quite unusual to have more than one volume partially full. If TSM assigned pages round-robin, then the usual case would be (fairly) even byte occupancy per volume. How do you get the occupancy of a database volume? With Q DBVOL I only see the available space (size of the formatted volume) and the allocated space (what is assigned to the database). In my case both are the same for all volumes. If you were right, I would get a problem on my new server, because I formatted three big volumes, each on a separate disk. If TSM only uses the first volume until it is full, then I would not benefit from the separate disk drives to get a higher performance. -- Regards, Dirk Kastens Universitaet Osnabrueck, Rechenzentrum (Computer Center) Albrechtstr. 28, 49069 Osnabrueck, Germany Tel.: +49-541-969-2347, FAX: -2470

Re: disk layout for db and log
Jim, Are you going to mirror at the hardware, OS, or application level? I'm going to mirror at the application (TSM) level. Spread the logical volumes across multiple disks at least two. The database, logs, and storage pool volume need to run on their own disks. The stgpool volumes are located in our SAN. If the database and log volumes go on separate disks, I would only have two disks for the db and one for the small recovery log (which are mirrored to the other three disks). I think it could be possible to have on disk with db AND log volumes on it and the other two disks with only db volumes. Or will this layout degrade performance too much? -- Best wishes, Dirk Kastens Universitaet Osnabrueck, Rechenzentrum (Computer Center) Albrechtstr. 28, 49069 Osnabrueck, Germany Tel.: +49-541-969-2347, FAX: -2470

Re: Incremental failure - NFS?
Hi, 3) Mount file system soft or hard soft NEVER mount an NFS filesystem 'hard'... if the NFS client EVER looses contact with the NFS server, it will hang and it WILL take a reboot to recover. By mounting 'soft', if the NFS clinet looses contact with the NFS server, the mount can be dealt with, ie. unmounted, with a little work. That's not a good advice, IMO. Only use the soft mount, if the filesystem is mounted read-only. Otherwise this could lead to data corruption. For read-write mounted filesystems, use the intr option. Here's an excerpt of the AIX Performance Management Guide: One of the choices you make when configuring NFS-mounted directories is whether the mounts will be hard (-o hard) or soft (-o soft). When, after a successful mount, an access to a soft-mounted directory encounters an error (typically, a timeout), the error is immediately reported to the program that requested the remote access. When an access to a hard-mounted directory encounters an error, NFS retries the operation. A persistent error accessing a hard-mounted directory can escalate into a perceived performance problem because the default number of retries (1000) and the default timeout value (0.7 second), combined with an algorithm that increases the timeout value for successive retries, mean that NFS continues to try to complete the operation. It is technically possible to reduce the number of retries, or increase the timeout value, or both, using options of the mount command. Unfortunately, changing these values sufficiently to remove the perceived performance problem might lead to unnecessary reported hard errors. Instead, use the intr option to mount the hard-mounted directories, which allows the user to interrupt from the keyboard a process that is in a retry loop. Although soft-mounting the directories causes the error to be detected sooner, it runs a serious risk of data corruption. In general, read/write directories should be hard-mounted. Dirk

I'm not a network expert, but why should I set the TCPWINDOWSIZE option to 63? The receive window size is determined in the following manner: 1. The first connection request sent to a remote host advertises a receive window size of 16K (16,384 bytes). 2. When the connection is established, the receive window size is rounded up to an even increment of the MSS. 3. The window size is adjusted to 4 times the MSS, to a maximum size of 64K, unless the window scaling option (RFC 1323) is used. Dirk
