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 are
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)

Parameters
- unit
- Specifies the unit for the size of the file. Possible values
are:
- -k
- Specifies kilobyte.
- -m
- Specifies megabyte. This is the default.
- -g
- Specifies gigabyte.
- file_type
- Specifies the type of file to be formatted. Possible values
are:
- -db
- Specifies the file is to be a database volume.
- -log
- Specifies the file is to be a recovery log volume.
- -data
- Specifies the file is to be a storage pool volume. This is the
default.
- file_name (Required)
- Specifies the name of the file to be formatted.
- size (Required)
- Specifies as an integer, the size of the file to be formatted. For
database and recovery log files, the allocated file size is always a multiple
of 4MB (plus an additional 1MB for overhead). The minimum file sizes
are 9MB for the recovery log, 5MB for the database, and 1MB for data storage
files
Examples
- Task 1
- 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:
dsmfmt -m -db dbvol1 9
- Task 3
- Format storage volumes backvol and archvol having
21MB and 9MB of storage respectively:
dsmfmt -m -data backvol 21 archvol 9
