NetWare v3.12 and SBACKUP on Apricot SCSI based servers

To be able to use SBACKUP, firstly ensure that the correct Disk Driver is loaded with its associated ASPI driver.

Apricot currently support four types of SCSI controllers.

AHA1510.DSK Adaptec AHA1510 Disk Driver. ASPITRAN.DSK the Adaptec ASPI driver is autoloaded.
AHA1640.DSK Adaptec AHA1640 Disk Driver. ASPITRAN.DSK the Adaptec ASPI driver is autoloaded.
AIC7770.DSK Adaptec AIC7770 Disk Driver. ASPITRAN.DSK the Adaptec ASPI driver is autoloaded.
BT312.DSK BusLogic BT-646S Disk Driver. BTASPI.DSK the BusLogic ASPI driver will need to be implicitly loaded.

Secondly Novell's ASPI Tape driver interface needs to be loaded.

TAPEDAI.DSK Novell's ASPI Tape interface.

For correct operation of SBACKUP, TAPEDAI.DSK should be loaded via STARTUP.NCF. If TAPEDAI.DSK is not loaded at start-up NetWare's operating system will not recognise any tape devices. To overcome this after loading TAPEDAI.DSK use the command "SCAN FOR NEW DEVICES" at the system console. The tape streamer will then be recognise by the operating system and function correctly. Loading TAPEDAI.DSK from STARTUP.NCF will eliminate the need for the "scan for new devices" command as the device will be available as the server initialises itself.

Thirdly, load any TSA modules that might be required.

TSA312.NLM Target Service Agent for v3.12 server.
TSA_DOS.NLM Target Service Agent for DOS clients. Used in conjunction with TSA_SMS.COM.

Finally load SBACKUP. Select the "DIBI- 2 DAI TAPE DRIVER". This option will prompt you to select a block size. All the associated block sizes have been tested on the Archive Python DDS and are software configurable. The same prompt will appear for a Archive Viper; however, the block size is jumper configurable and has been tested with both 512 & 1024K block sizes.

Example STARTUP.NCF

LOAD BT312 EXCLUDE_IDS=5,6
LOAD BTASPI
LOAD TAPEDAI

Example AUTOEXEC.NCF

FILE SERVER NAME NOVELL312
IPX INTERNAL NET 3271
LOAD 3C527 SLOT=2 FRAME=ETHERNET_802.3 NAME=3C527_2
BIND IPX TO 3C527_2 NET=FAB1
LOAD TSA_312
LOAD SBACKUP
LOAD MONITOR -P
