Resolving a problem with failure to boot

An IBM® Service Support Representative (SSR) can use this procedure to do a minimum configuration on a node canister if it fails to boot when powered on.

Before you begin

If the Storage Virtualize software is not running, then the node canister status and battery status LEDs are off. The service interfaces such as the service IP, technician port, and satask.txt on a USB flash drive do not work.
Note: If the canister services software on the PCIe switch chip finds that the microprocessors might not start, the node canister fault LED might be on with the node canister status LED off.

If the Storage Virtualize software is running, then the node canister fault LED might be on, and the node canister status LED might blink. The node canister error code and error data can be seen in the Service Assistant GUI, by connecting to the technician port, or by using the other service interfaces. Look up the error code in the FlashSystem 9500 IBM Documentation to find out what the error data means and what to do about it.

About this task

Complete the following steps if the Storage Virtualize software is not running on a node canister.

Procedure

  1. Use the management GUI or lseventlog CLI to look for any error events for the missing node canister.
  2. If secure boot has failed, then run the fix procedure for assistance with recovery. You might be directed to replace the boot drive with the fault LED on or to replace the node canister with the node fault LED on.
  3. If the microprocessors might not be started, run the fix procedure for assistance with recovery. You might be directed to try removing all adapter cages and DIMMs except for the DIMM in slot 2 and slot 14.
  4. If the Power On Self-Test (POST) on the microprocessor has failed, then run the fix procedure for assistance with recovery. You might be directed to try removing all adapter cages and DIMMs except for the DIMM in slot 2 and slot 14.
  5. If there is no error event about the missing node, complete the following steps:
    1. Power off the node canister by pulling out the node canister from the enclosure.
    2. Wait for 1 minute.
    3. Push the node canister back in to the enclosure and close the release latches.
      The node canister attempts to power on.
    4. If the power LED comes on green, then watch the node canister status indicator.
    5. If the node canister status LED remains off and there are no error events for the missing node, replace the node canister.
