Removing and installing an enclosure RAID module assembly with the power on in the Linux environment

Use this procedure to service an enclosure RAID module (ERM) assembly for the EDR1 PCI express (PCIe) storage enclosure (EXP30 Ultra SSD I/O Drawer) with the power on in the Linux environment.

Attention: Failure to follow the steps sequentially for this field-replaceable unit (FRU) removal or installation might result in damage to the FRU or system.

Use the following precautions whenever you handle electronic components or cables:

To remove and install an ERM assembly, complete the following steps:

  1. Use the service indicator light-emitting diodes (LEDs) to help identify the part. For instructions, see Identifying a part.
  2. To remove and install the ERM with the power on, iprutils version 2.3.12 or later is required. To update iprutils, see Updating the iprutils package.
    Is iprutils version 2.3.12 or later installed?
    Yes:
    Continue with the next step.
    No:
    The ERM cannot be replaced with the power on. Go to Removing and installing an enclosure RAID module assembly with the power off. This ends the procedure.
  3. On the Linux command line, type the iprconfig command.
  4. From the IBM® Power RAID Configuration Utility display, select Analyze Log, and press Enter.
  5. From the Kernel Messages Log display, select View ipr error messages, and press Enter.
  6. View the error message that indicates an adapter in a PCIe storage enclosure must be replaced. Record the PCI address of the adapter.
  7. Exit the Kernel Messages Log display by using the appropriate command for the editor that you are using.
  8. Type e and press Enter to exit the Kernel Messages Log display.
  9. From the IBM Power RAID Configuration Utility display, select Display hardware status, and press Enter.
  10. From the Display Hardware Status display, find the entry with the location of the adapter identified in step 5. Does the adapter have a status of Operational?
    Yes:
    Complete the following steps:
    1. Type 1 (Display hardware resource information details) next to the entry.
    2. Record the serial number shown on the IOA hardware Resource Information Details display.
    3. Type e to exit the display. Then continue with the next step.
    No:
    Use 00000000 as the serial number. Continue with the next step.
  11. From the Display Hardware Status window, find the PCI-E SAS RAID Adapter with a machine type and model of 57C3001SISIOA and a remote adapter serial number that matches the serial number identified in step 9. Type 1 (Display hardware resource information details) next to each PCI-E SAS RAID Adapter until the matching remote adapter serial number is found. Ensure that the Machine Type and Model on the IOA Hardware Resource Information Details display is 57C3001SISIOA. Record the PCI Address of the adapter.
  12. Return to the IBM Power RAID Configuration Utility display.
  13. From the IBM Power RAID Configuration Utility display, select Work with disk unit recovery, and press Enter.
  14. From the Work with Disk Unit Recovery display, select Work with disk enclosures, and press Enter.
  15. From the Work with disk enclosures display, find the adapter entry with the PCI address identified in step 11.
  16. Expander entries are located directly under adapter entries and have their PCI/Host/Resource Path information indented. Type 2 (Suspend disk enclosure path) next to the expander entry that is under the adapter entry identified in step 15, but has a different serial number than the adapter identified in step 15.
  17. From the Suspend Disk Enclosure display, type c to continue. Then type e two times to exit to the command line.
  18. Prepare to remove the ERM assembly:
    1. On the Linux command line, type lsslot -c pci to identify the slot location of the ERM assembly that you want to remove. Record the slot location.
    2. Type drmgr -R -c pci -s slot_location, where slot_location is the slot location of the ERM.
      For example, to remove the ERM assembly associated with slot U2C4E.001.DQD014E-P1-C2-T1-L1, enter the following command:
      drmgr -R -c pci -s U2C4E.001.DQD014E-P1-C2-T1-L1
    3. Follow the instructions on the display to complete the remove operation.
  19. Remove the ERM assembly:
    1. Disconnect the PCIe cables and serial-attached SCSI (SAS) cables (if present) from the ERM assembly, and mark each cable label with its location.
      Attention: Incorrect cable placement might result in data loss.
    2. Open the release lever (A) as shown in the following figure.
    3. Support both sides of the ERM assembly (B) while you slide it out of the enclosure.
    Figure 1. Removing an ERM assembly from the enclosure

  20. Are you here because you are replacing only the fan assembly?
    Yes:
    Return to the Removing and installing a fan assembly for an EDR1 PCIe storage enclosure procedure and replace the fan assembly. Then continue with the next step.
    No:
    Continue to the next step.
  21. Install the ERM assembly:
    1. Ensure that the release lever on the new ERM assembly is in the open position.
    2. Gently slide the ERM assembly into the enclosure until it stops.
    3. Push the release lever to the closed position.
    4. Reconnect the PCIe cables and SAS cables (if present) to the ERM assembly by using the location information marked on each cable in step 8a.
      Attention: Incorrect cable placement might result in data loss.
  22. On the Linux command line, enter lsslot to verify that the slot is occupied.

    For example, enter lsslot -c pci -s UEDR1.001.sssssss.

    The following output is an example of the information displayed by this command:
    # Slot          Description             Device(s)
    U5888.001.sssssss xxxxxxxx, xxxxx, 1xxxxxx slot 0001:40:01.0 
    Note: To prevent loss of enclosure information, do not replace both ERM assemblies at the same time. To replace the second ERM, complete the removal and installation procedures for the first ERM assembly, and then replace the second ERM assembly.
  23. On the Linux command line, type the iprconfig command.
  24. From the IBM Power RAID Configuration Utility display, select Work with disk unit recovery, and press Enter.
  25. From the Work with Disk Unit Recovery display, select Work with disk enclosures, and press Enter.

    Two adapters displayed. Each adapter has two expanders listed under it.

  26. Type 3 (Resume disk enclosure path) next to the expander entry that you identified in step 16.
  27. From the Resume Display Enclosure display, type c to continue. Then type e to exit the IBM Power RAID Configuration Utility.
  28. Are you here because you are replacing only the fan assembly?
    Yes:
    This ends the procedure.
    No:
    Continue with Updating the vital product data.

Updating the vital product data

The vital product data (VPD) must be updated after installing the ERM.

To update the VPD, complete the following steps:
  1. On the Linux command line, type drmgr -R -c pci -s slot_location, where slot_location is the slot location of the ERM that you recorded in step 18 of this procedure.
    For example, to replace the ERM assembly associated with slot U2C4E.001.DQD014E-P1-C2-T1-L1, enter the following command:
    drmgr -R -c pci -s U2C4E.001.DQD014E-P1-C2-T1-L1
    Follow the instructions on the display to complete the task.
  2. Do not remove the ERM assembly. Continue with the next step.
  3. From the Linux command line, enter lsslot to verify that the slot location of the ERM that you recorded in step 18 is occupied and does not have "Empty" in the Device(s) field.

    For example, enter lsslot -c pci -s U2C4E.001.DQD014E-P1-C2-T1-L1.

    The following output is an example of the information displayed by this command:
    # Slot          Description             Device(s)
    U2C4E.001.DQD014E-P1-C2-T1-L1 xxxxxxxx, xxxxx, xxxxxx  0001:40:01.0 

    This ends the procedure.
