Replacing a RAID Controller Card

Replacing a RAID Controller Card

A RAID controller card supports RAID levels, RAID level migration, and RAID configuration memory.

Impact on the System

Before replacing a RAID controller card, you must power off the storage node. This will adversely affect the services running on the node. Exercise caution when performing this operation.

Prerequisites

  • The replacement RAID controller card is ready.
  • The faulty RAID controller card has been located. Figure 3-195 shows the position of RAID controller card.
    Figure 3-195  Position of RAID controller card
  • You have obtained the OceanStor 9000 V5 Version Mapping and OceanStor 9000 V5 Node Firmware Upgrade Guide of the corresponding version.
    NOTE:
    You can log in to http://support.huawei.com/enterprise/, choose Support > Cloud Storage, and click the product model to go to the document page of the product. Then, click Downloads tab page. On the Downloads tab page, click the version that you need download, the download page is displayed. And then download the documents.

Precaution

  • Only professional technical support engineers are allowed to replace the RAID controller card.
  • A storage node has two power modules. Ensure that both are disconnected.

Tools and Materials

  • Flat-head screwdrivers
  • Phillips screwdrivers
  • Electrostatic discharge (ESD) gloves
  • ESD wrist straps
  • ESD bags
  • Labels

Procedure

  1. Wear an ESD wrist strap or ESD gloves.
  2. Use the KVM to log in to the operating system of the node, enter user name root and its password (default: Root@storage), and run poweroff command to power off the node.

    Wait until the KVM has no output. The power-off is complete.

  3. Remove all power cables and external signal cables.
  4. Remove the storage node from the enclosure.
    1. Loosen the captive screws on the storage node panel using a screwdriver, as shown in step 1 in Figure 3-196.

  17. Check RAID card configurations.

    When LSI SAS3008 RAID cards are configured for storage nodes, perform the following steps to check RAID card configurations:

    1. Use the KVM to log in to the operating system of a storage node as user root.
    2. Run the cd /opt/driver/lsisas-mpt3sas-driver; ./lsiutil_operateioc_ncqswitch.sh query command to check whether NCQ is Enabled.

      • If yes, go to 17.d.
      • If no, go to 17.c.

    3. Run the ./lsiutil_operateioc_ncqswitch.sh open command to open NCQ and check whether the output is open ioc ncq switch success, it will active after host reset..

      • If yes, go to 17.d.
      • If no, preserve the site, record the output, and contact technical service engineers.

    4. Run the cd /opt/driver/lsisas-mpt3sas-driver; ./lsiutil_operateioc_writecache.sh query command to check whether cache is Disabled.

      • If yes, go to 18.
      • If no, go to 17.e.

    5. Run the ./lsiutil_operateioc_writecache.sh close command to close cache and check whether the output is close ioc write cache success, it will active after host reset.

      • If yes, go to 18.
      • If no, preserve the site, record the output, and contact technical service engineers.

  18. Run the poweroff command to power off the storage node. Connect the storage node to peripheral devices through network cables according to the connection labels, and power on the storage node.
  19. Check and upgrade the firmware of a RAID controller card.
    1. On the node where the RAID controller card to be replaced resides, run the cd /opt/driver/lsisas-mpt3sas-driver; ./sas3flash -list command to view the value of Firmware Version, which is the firmware version of the RAID controller card.
    2. Check whether the firmware version of the RAID controller card (SAS card) recorded in the OceanStor 9000 Version Mapping is the same as the one you have obtained.

      • If yes, there is no need to upgrade firmware.
      • If no, go to 19.c.

    3. Upgrade the firmware of the RAID controller card to the required version by referring to the SAS Card Firmware Upgrade Guide. To obtain this guide, decompress the OceanStor 9000 V5 Node Firmware Upgrade Guide package.
  20. Inspect the system using SmartKit. Choose Home > Storage > Routine Maintenance > More > Inspection to check the system status. For details, see the OceanStor 9000 V5 Routine Maintenance.

    • If all inspection items are successful: The inspection is successful.
    • If some inspection items fail the inspection: The inspection is failed. Rectify the faults by taking recommended actions in the inspection reports. You need to reperform inspection after rectifying. If the inspection is still failed, contact Huawei technical support.

Follow-up Procedure

After replacing the RAID controller card, label the replaced RAID controller card to facilitate subsequent operations.
