Tivoli Storage Manager for AIX Administrator's Reference
Use this utility to use files, rather than logical volumes, for the TSM
database, recovery log, or disk storage pool volumes. Use DSMFMT to
pre-allocate the files so the server can use them. The parameters
positional but not case-sensitive.
- The DSMFMT utility does not destroy or modify an existing file.
- If a file does not format, DSMFMT issues an error message for that file
and then continues to format the next file on the list.
- If you are working with file sizes up to 2 GB and TSM is running on AIX
4.1, AIX may limit the file size. To set the user limit for file
size, perform one of the following:
- Edit and update /etc/security/limits
- Go to /smit/Security & Users/Users and change or show
characteristics of a user
- Issue the ulimit command (this only applies to the caller's
environment)
- If you need to work with file sizes greater than 2 GB and TSM is running
on AIX 4.2, you must perform one of the following:
- Specify the parameters in JFS that allow files to be greater than 2 GB
- Edit and update /etc/security/limits
- Go to /smit/Security & Users/Users and change or show
characteristics of a user
- Issue the ulimit command (this only applies to the caller's
environment)

- Format two recovery log volumes having 9MB of storage each:
dsmfmt -m -log logvol1 9 logvol2 9
- Task 2
- Format a database volume having 5MB of storage:
