reconfigScanDisk & SDDA Utilities - GOC3/GOC4

1 Overview

The DARC/DARC2 Node mounts the Disk Array. The reconfigScanDisk test wipes out all Scan (Patient) Data and reconfigures the Scan Disk. Additional commands are present. These tests 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 Procedure

notice The reconfigScanDisk 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.

Open a Unix Shell and type the following:

• {ctuser@ hostname }   su  -

• Password:  #bigguy

• [root@ hostname ]#   rsh  darc

• [root@darc ~]#   cd  /usr/g/scripts

• [root@darc scripts]#  ls  reconfigScanD*

  reconfigScanDisk

• [root@darc scripts]#   ./reconfigScanDisk  - or -  reconfigScanDisk

  An example output is shown below:

• [root@darc scripts]#  df  -h  /raw_data

  Filesystem 1k-blocks Used Available Use% Mounted on

  /dev/md0 71673044 2605820 69067224 4% /raw_data

  note:

  If /raw_data is not present then perform the ./startSDDA and df command again:

  • [root@darc scripts]#   ./startSDDA

  • [root@darc scripts]#  df  -h  /raw_data

• [root@darc scripts]#   exit

  rlogin: connection closed.

An additional command for the Disk Array is: [root@darc scripts]#  ./SDDAUtils  -U
