21.1 Managing CDs and DVDs as NSS Volumes (NetWare)

When you insert CDs and DVDs into the drive of a NetWare server, the removable media are loaded as read-only NSS volumes.

21.1.1 Understanding CDs and DVDs on NetWare

The cddvd.nss module must be loaded to support the handling of removable media on NetWare. The cddvd.nss module replaces cdrom.nlm and cd9660.nss for CD support, udf.nss for DVD support, and cdhfs.nss for Macintosh CD support. When you load cddvd.nss, it uses the same set of switches (UpdateCDToNDS, LoginUpdateToNDS, LeaveCDInNDS, and LockCDMediaIn) that were used in the previous commands.

The cddvd.nss supports the following disk formats:

  • Universal Disc Format (UDF) for DVDs

  • ISO 9660 for CDs

  • Hierarchical File System (HFS) for Macintosh CDs

By default, cddvd.nss loads the formats in sequential order, with the UDF format for DVDs first, ISO 9660 for CDs next, and CDHFS for Macintosh CDs last.

21.1.2 Mounting a CD or DVD as an NSS Volume

If a CD or DVD is in a drive when cddvd.nss loads, the disk is immediately activated as an NSS volume. Whenever the cddvd.nss module recognizes a newly inserted CD or DVD, it immediately activates the disk as a read-only NSS volume.

The volume name is the CD or DVD volume label, if one exists, and is acceptable to NetWare. Otherwise, cddvd.nss generates a volume name in this form: CD_ xxxx (where x is a number). This volume functions the same as any other NetWare volume, except that it is read-only.

21.1.3 Creating a Volume Object for a CD or DVD

Although the NSS volume is activated, it is not automatically added to Novell eDirectory™. You can add it to eDirectory by enabling the UpdateCDtoNDS switch.

  1. At the server console prompt, enter

    nss /UpdateCDtoNDS=cdname

21.1.4 Specifying the Load Order of Formats for Dual-Formatted

Disks in dual-formatted CD/DVD drives are activated as one volume and the format is decided by cddvd.nss. If you have an ISO/UDF bridge disk, which supports both ISO 9660 and UDF formats, you can instruct NSS to load ISO 9660 first with the LoadISOVolumeFirst switch.

To Load ISO 9660 format first:

  1. At the server console, enter

    nss /LoadISOVolumeFirst

21.1.5 Loading and Unloading the cddvd.nss Module

The cddvd.nss module loads automatically when NSS starts.

To load the cddvd.nss module manually:

  1. At the server console prompt, enter

    load cddvd.nss

To unload cddvd.nss:

  1. At the server console prompt, enter

    unload cddvd.nss
