There is a problem with DAG cluster backup in TSM. When you create script with /PREFERDAGPASSIVE key, your script return error 464 – nothing to backup. So I’ve created script to analyze Exchange’s databases if there is healthy passive copy of database to backup, so you run backup for the only healthy copy of database and for passive healthy copies of database. If there is nothing to backup than script returns 0.

Today we’ve found that one of our servers can make backups manually and works fine with polling mode, but when it is switched to prompting mode then schedule never run.

Recently we’ve found that one of our TSM servers stopped to back up all virtual machines. After examination of dsmerror.log files we’ve found strange messages:
03/20/2015 09:48:42 ANS0106E Message index not found for message 2252.
03/20/2015 09:49:01 ANS0106E Message index not found for message 14320.
03/20/2015 09:49:01 ANS0106E Message index not found for message 14180.
And so on.

One of the strange features of TSM AD pool is that, when you do first incremental backup (for example 10 files), then change some data (for example 5 files) you’ll get incorrect number of files with query occupancy stg=adpool command. It will show you number of files equal to 15, the same as in your primary storage pool. But if you compare sizes of pool you’ll see a difference. So do not rely only on file number in your AD storage pool.
