Configuration Files Used for the OSS Name Servers
The ZOSSFSET File
The ZOSSFSET file is an Enscribe alternate-key file that contains the fileset
configuration database. The ZOSSFSET file contains entries that identify the storage-
pool file and operating characteristics for each fileset in the OSS file system. Entries in
this file can be displayed with the SCF INFO FILESET command.
This file must be maintained by the system manager using the SCF ADD FILESET,
ALTER FILESET, DELETE FILESET, or RENAME FILESET command. It must be
present before the root fileset is first mounted.
Entries in the ZOSSFSET file must follow these rules:
•
The name of a fileset:
°
Can consist of 1 to 32 uppercase letters and digits (A through Z and
0 through 9). The first character must be a letter.
°
Must be unique.
•
The ZOSSFSET file must contain an entry for the root fileset.
An entry for the root fileset is automatically created in the ZOSSFSET file.
•
The device label of a fileset is a six-character value in the range 000000 through
0ZZZZZ. The characters can be 0 through 9 and A through Z (but not E, I, O, or U).
•
Fileset catalog volumes:
°
Cannot be on optical disks.
°
Cannot be on disks administered through the NonStop Storage Management
Foundation (SMF).
°
Should not be on the $SYSTEM disk, to avoid file security conflicts.
•
The pathname of the OSS file-system directory that the fileset is mounted on:
°
Must be the pathname of a directory that exists.
°
Is case-sensitive and must start with /.
°
Cannot begin with /G or/E.
°
Should be secured as “drwxrwxrwx” (0777, recommended for / and /home)
or “drwxrwxrwt” (1777, recommended for /tmp) in the OSS environment.
The root fileset mount-point directory must be /. The mount point of the root fileset
cannot be changed.
•
The only valid name for the OSS name server of the root fileset is #ZPNS. The root
fileset name cannot be changed.
