Other Volumes That NSS Creates

There are three Loadable Storage Subsystems (LSS) modules: ZLSS.NSS, CDHFS.NSS, CD9660.NSS, and DOSFAT.NSS. The ZLSS module provides access to logical volumes created by the user. The CD9660 module allows access to CD ROM drives as NSS volumes. The DOS FAT module allows access to FAT 16 and FAT 12 drives.


CD-ROMs As Logical Volumes

When NSS recognizes a CD ROM, it creates a Read-only logical volume for that CD ROM. This is done automatically when you load the CDROM.NLM. However, this volume is not added to NDS.

The new CDROM.NLM loads the CD9660.NSS and CDHFS.NSS modules. The CD9660.NSS module loads the ISO966, CDHFS, and Macintosh Hierarchical File System (HFS) file formats. Dual formatted CDs are mounted as two separate volumes. This means both Macintosh and Windows clients will see the same CD ROM volumes with two different layouts.

The CD9660.NSS module makes the contents of the standard ISO9660 CDROM available as a Read-Only logical volume. If the CDROM is in the drive when CD9660 loads, it will mount as a logical volume immediately.

The volume name displayed by the NetWare volumes command is the CD-ROM volume label if one exists. Otherwise, NSS generates a volume name in this form: CDXXXXXX (where X is a number). This volume functions the same as any other NetWare volume, except that it is Read-Only.

To load both the CD9660 and CDHFS modules, enter the following at the server console:

load cd-rom.nlm

To load CD9660.NSS alone, enter the following at the server console:

load cd9660.nss

To load CDHFS.NSS alone, enter the following at the server console:

load cdhfs.nss

To unload CD9660.NSS, enter the following at the server console:

unload cd9660.nss

To unload CDHFS.NSS, enter the following at the server console:

unload cdhfs.nss

The CD ROM unload process dismounts the volumes.


DVDs as Logical Volumes

Digital Versatile Disc (DVD), the newer optical storage technology, requires Universal Disc Format (UDF) support. DVD provides access time similar to CD-ROMs, has a bigger storage space, and records data in a universal format---meaning, you no longer need a plethora of different drivers to access the data.


Requirements

To mount a DVD as a logical volume, you need the following:


Mounting a DVD

At the server console, enter

LOAD UDF.NSS

To dismount a DVD, at the server console enter

UNLOAD UDF.NSS


DOS Partitions As Logical Volumes

After you load the DOSFAT.NSS module, any DOS FAT partitions are dynamically made available as logical volumes. The volume name displayed by the NetWare volumes command is DOSFAT_X, where X is the drive letter, for example DOSFAT_C.

The following are some benefits of the DOSFAT.NSS module:
