Too bad that there's no "preview=yes" when doing a generate backupset.
I checked 5.5 reference and 6.2 reference guide.

Hi All,

I have multiple RMAN backups running using NMDA 1.2 on Networker.
In networker itself, the retention is set to 4 weeks. Most RMAN backups do expire after 4 weeks.
On the RMAN side, the...

If I recall correctly, starting at TSM 5.5, it will list all the volumes required in the activity log prior to starting the generation. Did you have a look at the few lines right after you launch the...

Hi All,

I've been used to working with TSM and ProtecTIER, but now I have a client with EMC Networker and datadomain, which I'm just starting to learn. I've been tasked with implementing a second...

Your steps look ok to me. Since you don't have replication, you need to copy (backup stgpool) the data from the VTL. You can either do that before or after you've migrated the data to tape_pool.
...

oh nice Dynamox, that his really helpful!
still trial and error as you say, but it makes it faster to figure it out.

hi gbar,

sorry for the delay. Here's the actual patch link :

The Backup failure was the result of a vulnerability fix that had been issued by Microsoft that interfered with the System State...

yeah, exactly it doesn't give me the WWNs of the drives.. I still don't get why they won't show the WWNs or at least the SN of the tape drives on the data movers. That seems like basic info to me.

Hi KBEE, week-end patching also solved my issue!

Thanks for the links domino.

Thanks for your help KBEE, they're patching the windows systems this week-end. Hopefully that will solve the problem.

No it's often a different file name, but with the same RC=122 and RC=5 errors : The data area passed to a system call is too small.

I forwarded them some links about patches for the t2embed.dll...

Kbee, yes I'm seeing this on Windows 2008 VM machines and mostly on the new ones that were built by the windows team including the latest windows patches.
I did ask the Windows admins (good luck, as...

I upgrade to 6.3.0.0 hoping that it would solve the problem, but still having issues on more and more 2008 servers now. Anyone found a solution to this ?

Thanks Terlisimo. That's what I thought. Good to know that TSM changes the last access date whenever it backs up a file! That means that if they generate a report hoping to get the "last accessed...

Hi All,

I have a windows admin asking me if it's possible to archive a system based on the last accessed date of the files. I checked the documentation, and I do not see any options for that.
...

I'm actually planning on sharing the drives between usual TSM activity and NDMP. I'm not dedicating specific drives to the NDMP activity. That is why I'm not sure how to figure out that "c32t0l7" for...

Hi All,

I'm new to NDMP, and I just got the zoning done between my IBM TS7650G VTL and the 4 Celerra Data movers I have. The NAS admin just gave me a list of the drives seen on the data movers:
...

Hi,

Thanks for your answer. I think we found the problem.. looks like an IP configuration issue on the NAS itself, since the DFS root server can't even ping it! What's weird though, is that you...

when I try to access it, I'm logged into the DFS server as a domain admin, so I would think yes. I can map the drive and see the files with my user. The error message is "network path not found",...

Hi All,

We are currently moving our file servers from Novell to Windows 2008 with DFS. The disks behind the Novell servers used to be Symmetrix connected through typical fiber.

Now, they are...

Hi,

Just wanted to leave you feedback and thank you again for your help. With the filesperset = 1 correctly set up, I ran a second backup on the same database again, that didn't change at all...

you are right, I just checked through rman, and the only thing that was sent into separate backupset were the archived logs. The actual data files were sent together.

I just did a backup now as...

so I did a third test right now on a UAT database, that has not even changed since 2 days ago, and I get a dedup ratio of 1.00072 ! I'll try now with the archive logs outside the first run, like you...

Thank you so much for such a thorough answer. It now seems very clear to me and this was really helpful!

You are right, it was the second backup through tdpo. I'm working with the DBA to change...

OK, I must be missing something or something I don't understand still. You say the TDPO compressed about 4.9:1. How did you come to this number ?

Uncompressed size was: 165gigs
Change rate: 99%...

how dumb am I... I just did a tail -100 on the CSV, without looking at the first page with all the headers explaining what each columns actually are!

OK, so I was looking at the wrong columns!
I see I'm getting from protecTIER almost the same 1.000x factoring ratio on both backups. You are right, I only did one backup with TDPO to test, so dedup...

Hi,

Thank you so much for this detailed answer! I made sure filesperset were disabled. I'm running ProtecTIER 2.5.2 and I get the following info from the analyze_sessions when I run both...

Hello All,

I was wondering if there was a way to get the factoring ratio of specific cartridges instead of a global view ?

I'm getting a pretty bad global factoring ratio, and I'm pretty sure...

yep, I understand that, which is fine. The number is 100 gigs. The cartridge size is based on the post factoring ratio which is about 5:1 in my case. So from what I understand, I do need to update...

Hi All,

something I just noticed about the estimated capacity of the tapes on TSM from my VTL..

On the VTL, I defined 100 gigs as the size of the cartridges.
On TSM, I have a device class for...

I remember a bug that showed the error "no more drives are available" when it was not the case and I'm pretty sure it was in 5.4. Which specific version of 5.4 are you running?

Do you have drives...

I was wondering the exact same thing this week. I'm trying to actively monitor both of my ProtecTIER and I didn't find much information, except using the ptcli or ptmon tools, and then trying to...

wow, thank you for this solution!

I was trying to set up this kind of backup a couple of months ago for non-critical data.. got the error, couldn't find a solution and kind of forgot about it....

yeah, I did think about the reuse delay. I've always used the same number for the primary storage pools that I did for the copy pools so that wasn't really an issue. I know that a lot of people use 1...

you need at least one valid full database backup to be able to delete this one.

Just launch a full database backup, wait until it finishes... then try again a :
- del volh type=dbb todate=today

Random disks. I have less than 10 storage pools, so I do not need FILE class (which has mount points, and therefore causes unneeded loads on the TSM Server). I can arrange my disk space with small 10...

Well, the notion of "copy pool" is just a name. It is still a valid copy of all the cartdriges. The only difference is that TSM does not know about it.

Copy pools do not protect you any more from...

After lots of testing, I found that keeping most backups to a diskpool was better than sending everything to tape. First, TSM doesn't fare well when managing a lot of mount points (diskpools do not...

Can you ping the lanfree client from both TSM Servers ?

tsm prompt> ping server storageagent_name

I've just implemented a TS7650G with replication between the primary site and the secondary (DR) site.

I confirm that it does not use the copy storage pool command from TSM. Actually, TSM now sees...

Hi,

Thanks for your answer. I am at 5.5, yes. There was no TOC generated.

The "volumetry" means that they want to know how many gigabytes / terabytes are used by each backupsets. Since a lot of...

Hi All,

I'm working on a TSM Server that has been making backupsets for years now. Nobody wrote anywhere the volumes used, volumetry or nomber of files for each backupsets. I could get most of the...

Thanks a lot for the information!

yes that's exactly the problem. I can't get information from two TSM Tables at the same time as before, but I can get them while doing a single select...

weird.
