Error description
The Tivoli Storage Manager server issues the following message when the filesystem on which the db2 diagpath resides has less than 20% free space: ANR1545W The diagpath (/XXX/sqllib/db2dump ) file system or disk is becoming full. However, on very large filesystems 20% free space could be multiple gigabytes or even terabytes of space. The 20% threshold used to trigger this message is hardcoded and cannot be changed. TSM Admins need the ability to customize this value so that they can determine the appropriate threshold for the ANR1545W marning to be issued on their given server. The diagpath is where the db2diag.log resides. This file can grow indefinitely and can be a key contributor to the space used in this filesystem. Customer/L2 Diagnostics Example from actlog: ANR1545W The diagpath (/XXX/sqllib/db2dump ) file system or disk is becoming full. Total space used: 28,239,390 MB. Total space available: 32,270,696 MB. Percent full: 87.51 percent. The message ANR1545W is a bit misleading in this case as there is still 4TB space left in the filesystem. Tivoli Storage Manager Versions Affected: Tivoli Storage Manager server 6.1, 6.2 and 6.3 on all platforms Initial Impact: low Additional Keywords: zz61 zz62 zz63 TSM space left remaining directory
Local fix
Ignore the message if the 20% free space remaining is a significant amount

Problem conclusion
This problem has been corrected and the user documentation has been updated. 1. Information for the Administrator's Reference: In the Tivoli Storage Manager Administrator's Reference, the "SETOPT (Set a server option for a dynamic update)" topic was updated to list the new option, DBDIAGPATHFSTHreshold In the Tivoli Storage Manager Administrator's Reference, a topic was added to describe the new option: DBDIAGPATHFSTHreshold The DBDIAGPATHFSTHreshold option specifies the threshold for free space on the file system or disk that contains the db2diag.log file. When the amount of free space is equal to or less than the specified threshold, the ANR1545W error message is displayed. By default, the message is displayed when the file system or disk has 20% or less of free disk space. You can update this server option without stopping and restarting the server by using the SETOPT command. See SETOPT (Set a server option for dynamic update). Syntax >>- DBDIAGPATHFSTHreshold--percent--------------------------<> Parameters: percent Specifies the value of available space in the file system. Set a value from 0 to 100. The default is 20. Example Set the threshold value to 10 percent. setopt DBDIAGPATHFSTH 10 The same changes were made in the online help.
