Running hardware installation diagnostics

You run diagnostics after adding or replacing hardware components in your storage system to verify that the component has no problems and that the installation is successful.

Steps

  1. At the storage system prompt, switch to the LOADER prompt: halt
  2. Enter the following command at the LOADER prompt: boot_diags
    Note: You must run this command from the LOADER prompt for system-level diagnostics to function properly. The boot_diags command starts special drivers designed specifically for system-level diagnostics.
  3. Run the default tests on the particular device you added or replaced by entering the following command: sldiag device run [-dev devtype|mb|slotslotnum] [-name device]
    • -dev devtype specifies the type of device to be tested.
      • ata is an Advanced Technology Attachment device.
      • bootmedia is the system booting device.
      • cna is a Converged Network Adapter not connected to a network or storage device.
      • env is motherboard environmentals.
      • fcache is the Flash Cache adapter, also known as the Performance Acceleration Module 2.
      • fcal is a Fibre Channel-Arbitrated Loop device not connected to a storage device or Fibre Channel network.
      • fcvi is the Fiber Channel Virtual Interface not connected to a Fibre Channel network.
      • interconnect or nvram-ib is the high-availability interface.
      • mem is system memory.
      • nic is a Network Interface Card not connected to a network.
      • nvram is nonvolatile RAM.
      • nvmem is a hybrid of NVRAM and system memory.
      • sas is a Serial Attached SCSI device not connected to a disk shelf.
      • serviceproc is the Service Processor.
      • storage is an ATA, FC-AL, or SAS interface that has an attached disk shelf.
      • toe is a TCP Offload Engine, a type of NIC.
    • mb specifies that all the motherboard devices are to be tested.
    • slotslotnum specifies that a device in a specific slot number is to be tested.
    • -namedevice specifies a given device class and type.
  4. View the status of the test by entering the following command: sldiag device status
    Your storage system provides the following output while the tests are still running:
    There are still test(s) being processed.
    After all the tests are complete, the following response appears by default:
    *> <SLDIAG:_ALL_TESTS_COMPLETED>
  5. Verify that no hardware problems resulted from the addition or replacement of hardware components on your storage system by entering the following command: sldiag device status [-dev devtype|mb|slotslotnum] [-name device] -long -state failed
    Example
    The following example pulls up the full status of failures resulting from testing a newly installed FC-AL adapter:
    *> sldiag device status -dev fcal -long -state failed

    TEST END --------------------------------------------
    
    If the system-level diagnostics tests... Then...
    Were completed without any failures There are no hardware problems and your storage system returns to the prompt.
    1. Clear the status logs by entering the following command: sldiag device clearstatus [-dev devtype|mb|slotslotnum]
    2. Verify that the log is cleared by entering the following command: sldiag device status [-dev devtype|mb|slotslotnum]

      The following default response is displayed:

      SLDIAG: No log messages are present.
    3. Exit Maintenance mode by entering the following command: halt
    4. Enter the following command at the Loader prompt to boot the storage system: boot_ontap

    You have completed system-level diagnostics.

    Resulted in some test failures Determine the cause of the problem.
    1. Exit Maintenance mode by entering the following command: halt
    2. Perform a clean shutdown and disconnect the power supplies.
    3. Verify that you have observed all the considerations identified for running system-level diagnostics, that cables are securely connected, and that hardware components are properly installed in the storage system.
    4. Reconnect the power supplies and power on the storage system.
    5. Repeat Steps 1 through 6 of Running hardware installation diagnostics.

After you finish

If the failures persist after repeating the steps, you need to replace the hardware.
