Verify Status
The Read After Write Verify option is set to Hardware Level by default. This option cannot be specified in the startup.ncf or autoexec.ncf file. However, the
default can be set on the command line. Refer to the NetWare User's Guide for information about using the load command-line options.
The available options are defined in

Mount Status
Mounting causes a drive to come online as a NetWare storage device. Dismounted drives are inactive and cannot be accessed.
Before you eject the current media, dismount it. When the mount status is Dismounted, eject the media. However, NetWare does not allow you to dismount media
that are locked.
To insert your new media, wait for the drive to spin up, and then select the Removable Drive Mount Status option.
Lock Status
If your removable-media device supports the lock/unlock feature, you can lock the media. The media must be in the Not Locked state before you can eject it.
Using Drives Tested and Approved for NetWare
Adaptec 78x x series host adapters and their drivers are fully tested and approved for NetWare. This means that you can purchase a NetWare drive (certified as "Yes,
Tested and Approved") from a vendor, connect it to your system or host adapter, partition it, and create a volume without any compatibility concerns.
To be fully certified as NetWare "Yes, Tested and Approved," a drive and host adapter must both pass a qualification process that takes place before you see the
product. The goals of NetWare testing are to simplify installation and provide the highest quality disk subsystem.
Adaptec's adpu160.ham driver module is flexible enough to allow you to connect SCSI drives that are tested and approved for NetWare as well as standard SCSI
drives to a single host adapter. The driver registers each hard-disk drive accordingly.
Drive registration is a user-transparent process; no user interaction is required. You can tell that the drive has been detected as NetWare-tested and NetWare-
approved if the message NetWare Yes Tested and Approved is included in the drive description string that appears when you run monitor.nlm (disk options).
Using the NetWare Tape Backup Utility
Included with NetWare is a server-based tape backup utility called sbcon.nlm. This allows backup of server hard-disk drives to a server tape drive. The sbcon.nlm
utility supports Adaptec host adapters. To load the backup utility, perform the following steps:
1. Load the SCSI adapter driver by entering:
load [pathname]\aha160.ham [options] slot=x
The ASPI layer (nwaspi.cdm) is automatically loaded.
2. Refer to the Novell NetWare documentation for additional instructions on loading the server backup software. Refer to the NetWare Server Backup User's
Guide to load the tsa and sbcon modules.
