filename-case

This attribute controls the way file services handle the distinction between upper- and lower-case letters in file names in the volume. If you set this attribute to lower, file services handle names by translating them internally to lower-case file names. This simplifies file searches by name and results in an efficient implementation of the case-insensitivity expected by clients. Clients see file names in mixed case, but can use either case for any letters when supplying file names themselves. This file name handling can cause problems for UNIX applications that expect files to have the mixed-case names as supplied by clients.

If you set this attribute to preserve, file services look up names in their standard form in a shadow-attribute file. This allows file services to store files under UNIX in the same case-pattern used by the client, and still provide true case-insensitivity with reasonable efficiency.

If you do not define this attribute, or if you set it to default, you achieve the same effect as if you set it to preserve.

Usage:

tnvolume -M -v volume
 	-a filename-case={lower|preserve|default}
