386 V3.1

The NetWare 386 v3.1 drivers support the installation

multiple SCSI hard disk drives

- to increase total storage capacity

the system

Disk mirroring and disk duple xing are described below.

2.2.1

Mirroring

Disk mirroring refers to two

more hard disks which are installed on a single host

adapter. These disk drives contain the same data.

one disk goes bad, the rest will

continue to function without interruption to the end user, thus keeping network down

time to an absolute minimum.

data

The following hardware considerations should be taken into account when preparing the

AHA-I540/1542/l640/1740/1744 disk drives for mirroring.

- The NetWare partitions should

be nearly the same size. NetWare will not

allow partitions that vary greatly in size to be mirrored. Consult the

NetWare Installation manual for the limitations.

- The drives must

be connected to the same SCSI cable on the same AHA-

1540/1542/1640/1740/1744.

- The SCSI ID

the drives must

different.
