The sys: volume contains the NetWare system files and the NLM™ programs.
If the sys: volume does not mount when the server is booted, then the autoexec.ncf file does not execute, LAN drivers do not load, and the volume does not become part of the Novell eDirectory™ tree.
To diagnose problems when no volumes mount, identify whether the following conditions exist:
The sys: volume is corrupted.
The server disk containing volume sys: volume has failed.
The cable or power to the external server disks has malfunctioned.
To resolve problems when no volumes mount, do the following:
Repair the volume using the utilities that are appropriate for the volume type.
Check the cabling and power to the external server disks. Replace any faulty components.
Replace the server disk containing the sys: volume.
Create the partitions and the sys: volume.
Restore the data from a backup copy.
