In the previous chapter we installed the ICP Controller in a PCI computer and connected

the SCSI devices. Now these SCSI devices must be prepared in order to run with your oper-

ating system. This

Quick-Setup

chapter should help you to get started quickly. Quick-

Setup shows

four examples

on how a single SCSI hard disk, a Mirroring Array Drive (RAID

1), a RAID 5 Array Drive and a RAID 5 Array Drive with a Hot Fix drive are installed:

Example 1:

Installing a single SCSI hard disk.

Example 2:

Installing a Mirroring Array Drive (RAID 1), consisting of two

SCSI hard disks.

Example 3:

Installing a RAID 5 Array Drive, consisting of five identical

SCSI hard disks.

Example 4:

Installing a RAID 5 Array Drive, consisting of four identical

SCSI hard disks, and adding one Hot Fix SCSI hard disk.

Examples 3 and 4 are not applicable to ICP Controllers without the RAIDYNE firmware.

Even if you cannot practically carry out all the examples yourself, we suggest reading them

all the same because they will give you a better understanding of how the controllers of the

GDT RP Series work. The following table tells you which examples are applicable to your

type of ICP Controller.

<HV, when RAIDYNE Upgrade installed.

With examples 3 and 4 we shall briefly repeat the installation of the ICP Controller and the

SCSI devices, in particular with regard to disk arrays.

Some essential issues having direct impact on the structure and configuration of an Array

Drive with RAIDYNE will also be discussed:

1. How many physical SCSI hard disks are to be integrated in the Array Drive ?

2. Which redundancy level ought to be achieved ?

3. Should RAIDYNE automatically recover redundancy in the event of a disk

failure ? Or, in other terms: Are Hot Fix drives needed ?
