Resolving General Server Disk I/O Errors
Resolving Server Disk Space Problems
To resolve a general disk I/O error on the server, try one or more of the
following remedies:
Check the disk subsystems to make sure that the power is on and the
cables are correctly connected between the controller and the subsystems.
Make sure that the subsystem cables are terminated correctly.
Make sure that the hardware and disks are installed correctly.
Make sure that the current disk drivers loaded are certified for NetWare 6.
Many drivers can be found on the NetWare 6 Operating System CD or on
the master diskettes. Updated drivers might also be available from third-
party disk driver manufacturers.
Make sure that the interrupt parameters, I/O port settings, slot settings,
etc., for the driver match those for the hardware. Also, make sure that the
custom parameters have been set correctly for your hardware.
Make sure all devices are recognized.
Make sure that the device is visible and has a valid Hot Fix partition.
If you have tried all the preceding suggestions without success, contact your
Novell Support Provider or the drive manufacturer.
To resolve an insufficient disk space error, do one or more of the following:
Delete unnecessary files and directories from the volume.
Change the Minimum File Delete Wait Time SET parameter in your
server's AUTOEXEC.NCF file equal to 0 so that files can be removed
immediately rather than being retained in a salvageable state on the
volume.
Purge deleted files if they cannot be purged automatically. (The deleted
files are using up directory table space.)
Increase the volume size and/or add more disks to the volume.
Increase the percentage of disk space that can be used by a directory.
If the disk or volume does have space available, check the disk drives and
disk channel to see if a failure has occurred.
Delete NLM programs that you no longer use.
