Problem with expiration and log volume filling up.
Hi all Running TSM 5.5.2.0 on Solaris 9 I have started to see a problem now where the expiration process seems to get caught in some kind of loop where the log volume starts to fill up. At this point if I cancel the process it can sit there for over an hour with the log getting more and more full. In fact my only course of action when it last happened was the quickly add for log volumes to stop it getting to 100% capacity. Has anyone else seen this before and got any idea what's going wrong?

Flashcopy manager
Hi, I am currently working with Tivoli Flashcopy manager to create snapshots for application data (Exchange & SQL data in my case). I am using San volume controller to save my snapshots on space efficient volumes. I followed a guide for configuring all of this, but there is still one thing I do not understand. So here's my current configuration: I have created 2 source volumes and mapped them to my SQL server. Then i created 2 target volumes, mapped them to my VSS_FREE host. But then they say in the guide that during backups, these target volumes move to the VSS_RESERVED host. I don't understand why this happens. And also, are the target volumes exact copies of the source volumes? I found this a little bit vague in the guides. Also, can snapshots be made on the same volumes, or do new volumes get created? For example if you make 3 snapshots, are there 3 volumes created for this?

I don't understand why this happens. This is done under the covers by the IBM Hardware VSS Provider for SVC. It does this so those LUNS are not utilized by VSS operations from other machines performing VSS snapshots. For persistent snapshots, (BACKUPDESTINATION=LOCAL), the VSS snapshot LUNS will assigned to the machine that performed the snapshot until the backup expires. >> And also, are the target >> volumes exact copies of the source volumes? I found this a little >> bit vague in the guides. Logically, they are exact copies. Physically, there are two types: 1. THIN-PROVISIONED, which only contain the changed blocks 2. FULL COPIES, which contain a duplicate copy of the LUN >> >> Also, can snapshots be made on the same volumes, or do new volumes >> get created?

Flashcopy manager
very much obliged for the answer. I understand it somewhat better now. Could you perhaps post a new link to that whitepaper, because the link doesn't seem to be working. Thank you +-- |This was sent by koekiesfre...@hotmail.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +--
Re: Flashcopy manager
Sorry... I had pasted the internal link. Here is the external link: http://www.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP101639 Here is another link that might help with a conceptual view: http://www.ibm.com/developerworks/tivoli/library/t-tsm-vss/index.html It discusses TSM and VSS. It is a few years old, but the concepts remain the same. Note that it refers to TSM for Copy Services, which is the former name of FlashCopy Manager. >> very much obliged for the answer.

licensing question
We are thinking about adding an additional TSM server to our environment to use for an offsite DR. Basically we would duplicate our onsite data to the new offsite TSM server. How would we go about licensing for the additional server? Or does it matter? Thanks David Tyree Interface Analyst South Georgia Medical Center 229.333.1155
Restoring backedup data in TSM
Hi all, I have backup some files in a local direcotry from TSM and got a image file 0165.bfs. Now i want to restore all those files from this 0165.bfs . when i am using dsmc restore command it is simply giving me back 0165.bfs . I want to have original files not the image itself. Can anybody help me in this ?? +-- |This was sent by devesh.gu...@nechclst.in via Backup Central. |Forward SPAM to ab...@backupcentral.com. +--
