Step-by-Step Procedure

Time needed: 30 minutes

This guide outlines the steps required to replace the Hard Drive 5308760-3 and 5308760 in the High Speed Disk Array (HSDA), providing detailed descriptions for each step.

  1. Verify HSDA RAID Controller Firmware Compatibility

    Open a terminal window and type: ssh darc [Enter]. Next, type: lsscsi [Enter]. Verify FW version on the list of SCSI devices. When using HDD FRU 5308760-3, make sure the firmware matches or is updated to version 371E, as this version supports any mix of HDD FRU 5308760-3 and 5308760. For compatibility with HDD FRU 5308760, firmware versions 363B and older are suitable.

  2. Shut Down (Power Off) CT Console

    Click the Shut Down icon and select Shut Down option. Alternatively, open a Unix Shell and type: halt [Enter]. Ensure “System Halted” message is displayed on the monitor, then power off the console at the front panel switch. Remove twist-lock main power cable from the console rear and perform LOTO.

  3. Remove Front Console Cover

    Loosen the lock assemblies and gently extract the front console cover.

  4. Remove defective HSDA HDD From Tray

    To unlock the HDD Tray Door, press the HDD Tray Door Release Button (bottom center of HDD). Next, lift the HDD tray up and out of the assembly.

  5. Transfer Tray and Hardware (If Necessary)

    Unscrew the 4 Phillips screws that secure the tray to the defective HSDA HDD. Transfer the tray and hardware to the new HSDA HDD, if necessary.

  6. Install new HSDA HDD

    Insert the new HSDA HDD into the slot of the HSDA assembly, ensuring it is full seated. Close the HDD Tray door, allowing it to snap into place naturally without the need for force.

  7. Power-On Console

    Connect twist-lock main power cable at the rear of console. Flip the power switch to the on position at the front of the CT operator console. Cancel system startup when the pink CT Software Auto Start Message appears. Visually verify HSDA assembly LCD panel is illuminated.

    Important: DO NOT ALLOW CT APPLICATIONS TO START AT THIS POINT. Cancel startup when the pink CT Software Auto Start Message appears.

  8. Verify HDD Status

    Check that the HSDA HDD LED panel is error-free, and confirm that the LED status indicators for all hard drive trays are green. Note that the HDD status LED will display yellow during bootup and should transition to green after approximately 2 minutes.

  9. Rebuild Scan Disk Array

    Open a unix shell and login as root, type: su – [Enter]. Enter password to login as root user. Type, reconfig [Enter]. Under the System Tab, select Yes next to Rebuild Scan Disk Array. Next click Accept at the top right of the window. The system will now rebuild the scan disk array. This process takes about 15 minutes.

  10. Shutdown System and Restart

    Once system has booted, exit out of the pink Auto-Start Failed message screen and perform a complete shut down. Open a Unix shell and type: halt [Enter]. System will begin shutdown. Once “System Halted” message appears, flip the console power switch to the Off position. Wait 1 minute and flip power switch to the On position. Once system has booted, open a Unix Shell and type: st [Enter].

  11. Finalization

    Perform a system sanity scan to verify system functionality. Reinstall front operator console cover.
