gre-raid Disk Array Tests - GOC3/GOC4/AIO

1 Overview

The DARC/DARC2 Node mounts the Disk Array. The -c (create) command wipes out all Scan (Patient) Data and reconfigures the Scan Disk. The -c and -a tests must be run with Application Software down. The -q (query) test may be run with Application Software up or down.

Additional commands have been provided to see if the RAID is mounted and the disks are present, in Verify Disk Present and Mounted.

note:

For All-In-One Console, there is no DARC node presence. CDIP card and scan data disks are mounted in Host computer.

All the commands ran on DARC node still can be ran on Host computer. It’s not necessary to run “rsh darc” for AIO console.

2 Determine Software

For CT confirm the Host Application Software is equal to or greater than 06MW03.4. If the software is less than 06MW03.4, do NOT perform this procedure.

FOR PET systems this is only applicable to pet_libhp1.39, dm09_dvctsp1.23 and dm09_hl2sp1.23 software revisions.

  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 for CT must be: 06MWxx.xhardware revision info (or greater)

    Output for PET must be: pet_libhp1.39, dm09_dvctsp1.23 or dm09_hl2sp1.23

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

3 Procedure

The Disk Array is configured with 2 disks (internal to the SDDA or the DARC2). As required, perform the create, assemble or query commands. Visually verify the entire output is successful from the command script performed. The final output line ‘gre-raid success’ does not mean the 2 Disk Array RAID is good. Shutdown Application Software if it is up. Open a Unix Shell and type the following:

{ctuser@ hostname } cleanMon

3.1 Create (-c) Script

Notice Image
  • notice
  • The sudo gre-raid -c (create) script erases all data on the Scan Disk. Patient information WILL be lost. Make certain to back-up all patient data prior to performing this test.

With Application Software down, open a Unix Shell and type the following:

{ctuser@ hostname }   rsh  darc

[ctuser@darc ~]$   sudo  gre-raid  -c

note:

For PET systems running pet_libhp1.39 do NOT run the sudo gre -raid -c command. Run command: /usr/g/scripts/reconfigScanDisk


            ************************** Warning ******************************
* If a new disk array is created, all scan data on the current  *
* disk array will be lost.                                      *
*****************************************************************


          

Are you sure you want to create a new disk array (yes/no)?   yes

Verify the create partitions diagnostic passes and all output looks good.

Perform the assemble and query commands if the create has been successful.

3.2 Assemble (-a) Script

With Application Software down, open a Unix Shell and type the following:

{ctuser@ hostname }   rsh darc

{ctuser@darc}   sudo gre-raid -a

Verify assemble diagnostic passes and all output looks good.

Perform the query command if the assemble has been successful.

3.3 Query (-q) Script

With Application Software up or down, open a Unix Shell and type the following:

note:

A query can be performed at any time with Application software up or down. The preferred method is to test with Application software down. The Operator Console can not be scanning or manipulating Scan Data during the testing.

{ctuser@ hostname }   rsh darc

{ctuser@darc}   sudo gre-raid -q

Verify query diagnostic passes and all output looks good.

{ctuser@darc}   exit

{ctuser@ hostname }

4 Verify Disk Present and Mounted

Open a Unix Shell and type the following commands to verify two 36 GByte disks (alternate disk manufacturers may be shown) are present. Additionally, /dev/md0 can be checked to see if /raw_data is mounted using the df or df /raw_data command.

{ctuser@ hostname }   rsh darc

{ctuser@darc}   df /raw_data

{ctuser@darc}   df

{ctuser@darc}  cat /proc/scsi/scsi
