Disabling caching on a primary stgpool and deleting the volumes in TSM
I recently needed to shrink a primary stgpool with devclass DISK on a TSM 5.5 server in order to free up space. Since the stgpool had a device class of DISK and caching was enabled, I wasn’t able to directly shrink the stgpool by moving the data within volumes and then deleting the empty volumes. ...
TSM 6.2 shut down, ADM6017E in db2diag.log
This morning, I noticed that one of my TSM 6.2 servers had stopped running over night. No DB2 processes or dsmserv were running. I checked the TSM logs, but only found errors from the dsmadmc client: 08/11/11 09:08:52 ANS5216E Could not establish a TCP/IP connection with address ‘TSM1.LANIGERA.COM:1500′. The TCP/IP error is ‘Connection refused’ (errno ...
TSM 6.2.3 released
IBM has released Tivoli Storage Manager v6.2 Fix Pack 2 (6.2.3). Looks like a lot of bugfixes, in particular a DB2 reorg bug. As usual, I’ll let everyone else go first and see what breaks. Thanks, dudes!
Enabling deduplication on a primary storage pool in TSM 6.2
I recently had the need to enable deduplication on an existing 5.5TB storage pool residing on a TSM 6.2 server. The storage pool has a FILE (disk-based sequential access) device class, and is used to store virtual volumes from a remote 5.5 server. So, even though it is configured as a primary pool, its ...
Oracle and TSM for Databases: Part 2
In the first installment of this series, I discussed some of the basic concepts in using Tivoli Storage Manager for Databases to backup and recover Oracle databases. In this installment, we’ll look at how to keep TSM and Oracle in sync. When backing up a typical filespace, the TSM backup-archive (BA) client compares what files ...
EMC Record Breaking Tour
EMC brought their “Record Breaking Tour” through St. Louis this week. Since I’ve had little exposure to EMC storage, I thought it would be worth going to familiarize myself with their product portfolio. They did have some of their new marketing on display. There was a Mini Cooper in the lobby, and each segment of ...
Storage at Home – Drobo vs Whitebox
“Mr. Backup,” W. Curtis Preston, has changed his mind about Drobo. Preston recently made some waves on the internets when his unit failed and he found Data Robotics’ customer service lacking, so he unloaded with both barrels. I’ve followed news about Drobo with some interest, as I’ve been pining for a decent home NAS solution ...
Oracle and TSM for Databases: Part 1
One of the most confusing areas for TSM admins is backing up Oracle databases using TSM for Databases (frequently referred to by its old name, Tivoli Data Protection or TDP). In this series, I’ll provide an overview of how to use TSM to backup Oracle databases, with a special emphasis on problems you may face ...
Cloning Oracle databases with RMAN
Some of the hats I currently wear include being the backup administrator and sometime DBA. The two overlap, since I use IBM’s Tivoli Storage Manager (TSM) to handle all of our Oracle-related backups and restores. By restoring backups of a production environment to a nonproduction one (eg, a development or testing instance), you can make ...
