testHighSpeed Script - GOC3/GOC4 Disk Array

1 Overview

The DARC (or DARC2) Node mounts the Disk Array drives. The GOC3 SDDA houses two Scan Data Disk Drives and the Intercom / Prescribed Tilt Board. The GOC4 DARC2 Node houses the two Scan Data Disk Drives. This test verifies the SCSI cabling (internal or external) for the Disk Array. It writes data to the drives, then reads it back and verifies a checksum looking for dropped packets. It ensures the Disk Array RAID is able to transfer data at a rate equal to or greater than 75 MB/sec. This test shall be run with Applications down.

2 Determine Software

Confirm the Host Application Software is less than 06MW03.4. If the software is 06MW03.4 or greater, do NOT perform this procedure.

  1. Open a Unix Shell and type the following to verify Applications software version information. Examples are provided. The examples are not actual output.

    {ctuser@ hostname }  swhwinfo

    (year)MW(fiscal week).(fiscal day).hardware revision info here

    Output must NOT be: 06MWxx.xhardware revision info (or greater)

  2. If the software version is less than 06MWxx.x continue. If it is equal to 06MWxx.x or greater, do not continue.

3 testHighSpeed

(For SDDA Only) Visually verify the front panel SDDA LEDs for HD1 and HD2 blink during the test.

Open a Unix Shell and type the following:

{ctuser@ hostname }   rsh  darc
