NSS Configuration Information Commands

• nss /modules Lists the providers, loadable storage subsystems, and semantic agents.
• nss /status Lists the current NSS status.
• volumes Lists all NetWare and NSS volumes that are mounted, including Admin volume.
• nss volumes Lists all NSS volumes, including the Admin volume.

Start Up NSS Commands

The following commands are only valid when NSS is loading:

• nss /NumWorkToDos=value Sets the number of WorkToDo entries which may be concurrently executing. NSS uses WorkToDo entries for tasks such as flushing file metadata to disk in the background. Increasing the number of WorkToDo entries might be useful on a system that is heavily used. NSS always reserves 20 WorkToDo entries. The default is 40. The range is 5 to 100.
• nss /MailBoxSize=value Sets the size of your mailbox. The default is 228. The range is 64 to 256.
• nss /NumAsyncios=value Sets the number of asynchios entries to allocate. The default is 2048. The range is 4 - 65536.
• nss /Numbonds=value Sets the number of bond entries to allocate. The default is 5000. The Range is 512 - 2097152.
• nss /(No)skipLoadModules Skips the auto loading of the NSS support modules. StartupOnly Value=Off.
• noLSS If specified, does not load any LSS modules.
• allLSS Loads all the LSS modules.
• defaultNLMs Loads only default NSS NLMs and any additional LSS modules specified on the command line.
• CD9660 Loads only those modules that are essential for CD9660 support.
• CDHFS Loads only those modules that are essential for CDHFS support.
• CDROM Loads only those modules that are essential for CD9660 and CDHFS support.
• DOSFAT Loads only those modules that are essential for DOSFAT support.
• UDF Loads only those modules that are essential for UDF support.
• zLSS Loads only those modules that are essential for zLSS support.

Modifying NSS Startup Commands After NetWare 6 Has Booted

1. Create a file called NSSSTART.CFG.

2. Enter any NSS startup commands that you want to modify after NetWare 6 has booted.

   Each NSS command should be proceeded by a forward slash (/) and ended with a space. For example:

   /xxxxx /xxxxx /xxxxx

3. Place the file in the same directory as SERVER.EXE.

Other NSS Commands

IMPORTANT:  This is not a complete list of NSS commands. To see a complete listing, type nss /help at the server console.

• nss /Activate=volume_name Activates an NSS volume.
• nss /Deactivate=volume_name Deactivates an NSS volume.
• nss /Maintenance=volume_name Switches the specified NSS volume to maintenance mode.
• nss /ForceActivate=volume_name Forces an NSS volume to become active.
• nss /StorageAlarmThreshold=value Lets you set the threshold for a low storage space warning. The default is 10. The range is 0 to 1000000.
