    1 Understanding LED Indicator Status NOTE: References to 7200 models imply 7200/7200c. References to 7400 models imply 7400/7400c/7440c. Storage system components have LEDs to indicate status of the hardware and whether it is functioning properly. These indicators help diagnose basic hardware problems. You can quickly identify hardware problems by examining the LEDs on all components using the tables and illustrations in this chapter.

    The defective part must be returned with the associated documentation in the provided shipping material. Failure to return the defective part could result in HP billing you for the replacement. With a CSR, HP pays all shipping and part return costs and determines the courier/carrier to be used.

  • Page 27: Accessing Replacement Videos

    Your HP Limited Warranty may include a parts-only warranty service. Under the terms of parts-only warranty service, HP provides replacement parts free of charge. For parts-only warranty service, CSR part replacement is mandatory. If you request HP to replace these parts, you are charged for the travel and labor costs of this service.

  • Page 28: Swappable Components

    Disk drives are warm swappable even though they have yellow touch points. However, they should only be removed on the advice of a qualified 3PAR administrator or HP service technician after the fault LED is turned on, and after all the data has been vacated and reconstructed to other drives.

    At the HP Storage Systems Guided Troubleshooting web site, follow the link for your product. At the bottom of the HP 3PAR product page, click the link for HP 3PAR Alert Messages. At the bottom of the Alert Messages page, choose the correct message code series based on the first four characters of the alert message code.

  • Page 30: Powering On

    Select Halt a StoreServ cluster/node. Follow the prompts to shutdown an HP 3PAR StoreServ cluster. Do not shut down individual Nodes. Allow 2-3 minutes for the node to halt, then verify that the node Status LED is flashing green and the node hotplug LED is blue, indicating that the node has been halted.

    In the Locate Cage dialog box, enter an appropriate time to allow service personnel to view the LED status of the Drive Enclosure (Cage). See Figure 36 (page 35). NOTE: If necessary, use the Stop Locate icon to halt LED flashing. Figure 36 Locate Cage Dialog Box An icon with a flashing LED will be shown next to the cage, which flashes all drives in this cage except the failed drive.

  • Page 36: Installing A Disk Drive

    To reinstall a new disk drive, see “Installing a Disk Drive” (page 36). Figure 38 Removing a 3.5 inch disk drive Installing a Disk Drive CAUTION: Blank disk drive carriers are provided and must be used if all slots in the enclosure are not filled with disk drives.

  • Page 37: Installing A 2.5 Inch Disk Drive

    Figure 39 Installing a 2.5 inch disk drive Observe the newly installed disk drive for 60 seconds to verify the amber LED turns off and remains off for 60 seconds. Installing a 3.5 inch disk drive (LFF) Press the handle latch to open the handle. Position the disk drive so the handle opens from the left and slide it into the enclosure.

  • Page 38: Verifying Disk Drives

    CAUTION: Alloy gray-colored latches on components like the node means that the component is warm-swappable. HP recommends that the node be shutdown (with the power remaining on) before removing this component. Contact your ASP for node diagnosis and shutdown. CAUTION: To prevent overheating, node replacement requires a maximum service time of 30 minutes.

  • Page 39: Node Identification And Shutdown

    Replace the node cover: While aligning the node rod with the cutout in the front, and the guide pins with the cutouts in the side, lower the node cover into place. Tighten the two thumbscrews to secure the node cover to the node. Pull the gray node rod to the extracted position, out of the component.
  • Page 40 If a PCIe adapter is installed in the failed node, move the SFPs from the PCIe adapter on the failed node to the PCIe adapter on the replacement node: Lift the retaining clip and carefully slide the SFP out of the slot. Carefully slide the replacement SFP into the adapter on the replacement node until fully seated.

  • Page 41: Node Verification

    The SFP is located in the port on the controller node HBA/CNA and there are two to six SFPs per node. Before you begin, use either SPMAINT or the HP 3PAR Management Console to identify the failed SFP. SFP Identification Under the Systems tree in the left panel, select the storage system to be serviced.

  • Page 46: Using Strong Passwords

    If you choose encrypted ciphertext passwords, you need to export the ciphertext and provide it to the HP personnel working with you. The ciphertext is pasted into a tool at HP that can unwrap and decrypt the ciphertext to recover the password. After the support activity is complete, you can change the password so that the recovered password is no longer valid.

  • Page 47: Setting Or Changing The Password Mode

    Setting or Changing the Password Mode To query or change the current setting of the strong service account password system, use the 3PAR CLI command controlrecoveryauth (to change the mode from time-based to encrypted ciphertext, for example). To query the current mode, use the command controlrecoveryauth status. To change the mode, use the command controlrecoveryauth setmethod [totp|ciphertext], choosing either totp (time-based passwords) or ciphertext.
