Configuration Files Used for the OSS Name Servers
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.
•
When the BUFFERED CREATE (fast-create) attribute is set for a fileset:
°
The fileset cannot use more than one volume.
°
The fileset catalog must reside on that volume.
°
The storage-pool file specification is ignored and the storage pool used for file
creation (the creation pool) is the catalog disk volume.
The BUFFERED CREATE attribute controls buffering of new file labels by the disk
process. When this attribute is set, the labels for new files created on this fileset
are kept in memory until the disk process has no other work to perform; then the
labels are written to disk. When this attribute is not set, labels are written to disk
immediately.
