Hi all, Got nothing to do with Atape driver. I posted about these issues on 31-Jan (search for " Be Aware: TSM 6.2.3 & AIX 7 TL2 FP2 don't mix")
Raised a case about it but got the following answer back from IBM: TSM 6.2 is not supported on AIX6 TL7. Either roll back to AIX6 TL4 or update to AIX7 Best Regards, Oscar -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Clark, Margaret Sent: 01 March 2012 22:10 To: [email protected] Subject: Re: [ADSM-L] Slow TSM DB Backup No, we're still using 11.6.0.0. - Margaret -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Lamb, Charles P.

Atape V12.4.1.0 It did somewhat help, however, the TSM DB backup takes us 1 1/2 for full, TSM DB snapshot takes us 2 1/2hrs with our 100GB of data in our 340GB DB2 database. They were about 10-15 minutes in length before we performed the AIX migration from V5.3.12.3 to V6.1.7.3. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Clark, Margaret Sent: Thursday, March 01, 2012 2:09 PM To: [email protected] Subject: Re: [ADSM-L] Slow TSM DB Backup Should have mentioned: we upgraded to AIX 6.1 TL 7.1 at the same time as the upgrade to TSM server 6.2.3.1. We upgraded to AIX 6.1 TL 7.0 on Jan 12th, and of eleven database backups before adding the 7.1 patches, two were exceptionally long - unprecedentedly long at that time, between 5 and 6 hours. We're up to one long database backup out of the last six now, since resetting REORGDURATION and making sure DB backup is not during the reorg window. - Margaret -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Lamb, Charles P.

We are experiencing slow TSM DB backup process on both of our TSM systems using AIX V6.1.7.x, TSM V6.2.3.100, Atape v12.4.1.0. The issues began immediately after we upgraded from AIX v5.3.12.3 to AIX v6.1.7.x. We have created a performance PMR#53387,379,000 with TSM support. With 100GB data in a DB2 database, we are seeing 30 to 60sec waits between .1/.2GB database transfers to IBM LTO4 tape drives via TSM q se screen. It is taking a very long time to complete a TSM DB backup. Before the AIX upgrade, the full DB backup took about 10 minutes; now we are seeing backups of hours in length. Anybody having these types of issues?? ***************************************************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
