Replacing an SSD Card Used as the Cache

Replacing an SSD Card Used as the Cache

This section applies only to TaiShan 2280 V2 12-slot nodes, TaiShan 2280 V2 25-slot nodes, and TaiShan 5280 V2 36-slot nodes.

SSD cards can be used as the cache of the storage system.

Impact on the System

Before replacing an SSD card on a storage node, you must power off the node. This will adversely affect the services running on the node.

Prerequisites

  • A spare SSD card is ready.
  • The faulty SSD card has been located.

Precautions

None

Tools and Materials

  • Flat-head screwdrivers
  • Phillips screwdrivers
  • ESD gloves
  • ESD wrist straps
  • ESD bags
  • Labels

Procedure

  1. Obtain the ESN of the faulty SSD card.

    1. Log in to DeviceManager, and choose Services > Block Service > Storage Pool.
    2. Click in the row where the desired storage pool resides, and select Disk Topology from the shortcut menu.
    3. Move the cursor to the faulty SSD card. SN that is displayed is the ESN of the faulty SSD card.

  2. Log in to the primary management node as user dsware, and run the sh /opt/dsware/client/bin/dswareTool.sh --op setServerStorageMode -ip Management IP address of the faulty node -mode 1 command to switch to the maintenance mode. To run this command, enter the name and password of CLI super administrator account admin as prompted.
  3. Remove the storage node from its cabinet and remove the chassis cover. For details, see Basic Operations.
  4. Remove the PCIe card from the riser card.

    1. Lift the riser card tray, as shown in the following figures.
      Figure 10-1 Removing the riser card tray of a TaiShan 2280 node
      Figure 10-2 Removing the riser card tray of a TaiShan 5280 node
    2. Horizontally push the latch of the PCIe card outward to unlock it, as shown in step 1 in Figure 10-3.
      Figure 10-3 Removing the PCIe card from a riser card
    3. Rotate the PCIe card latch to open it, as shown in step 2 in Figure 10-3.
    4. Pull out the PCIe card, as shown in step 3 in Figure 10-3.

  5. Place the removed SSD card in an ESD bag.
  6. Take the spare SSD card out of its ESD bag.
  7. Install the PCIe card on the riser card.

    1. Insert the PCIe card into the PCIe slot, as shown in step 1 in Figure 10-4.
      Figure 10-4 Installing a PCIe card on the riser card
    2. Close the latch on the PCIe slot, as shown in step 2 in Figure 10-4.
    3. Install the riser card tray, as shown in the following figures.
      Figure 10-5 Installing the riser card tray of a TaiShan 2280 node
      Figure 10-6 Installing the riser card tray of a TaiShan 5280 node

  8. Install the chassis cover and put the storage node into the cabinet. For details, see Basic Operations.
  9. Obtain the ESN of the spare SSD card.

    1. Log in to DeviceManager, and choose Services > Block Service > Storage Pool.
    2. Click in the row where the desired storage pool resides, and select Disk Topology from the shortcut menu.
    3. Move the cursor to the spare SSD card. SN that is displayed is the ESN of the spare SSD card.

  10. Optional: If the faulty SSD card has not been removed from its storage pool, run the following command to add the spare SSD card to the storage pool. When running the following command, enter the name and password of CLI super administrator account admin as prompted.

    sh /opt/dsware/client/bin/dswareTool.sh --op forceReplaceSSD -id ID of the storage pool to which the faulty SSD card belongs -oldEsn ESN of the faulty SSD card -newEsn ESN of the spare SSD card -nodeMgrIp Management IP address of the faulty node -type cache -ignoreMediaFault true

  11. Optional: If the faulty SSD card has been removed from its storage pool and the spare SSD card is not automatically added to the storage pool, run the following command to add the spare SSD card to the storage pool. When running the following command, enter the name and password of CLI super administrator account admin as prompted.

    sh /opt/dsware/client/bin/dswareTool.sh --op updateSSDCacheESN -poolId ID of the storage pool to which the faulty SSD belongs -oldEsn ESN of the faulty SSD -newEsn ESN of the spare SSD -nodeMgrIp Management IP address of the faulty node

  12. Log in to the primary management node as user dsware, and run the sh /opt/dsware/client/bin/dswareTool.sh --op setServerStorageMode -ip Management IP address of the faulty node -mode 0 command to switch to the normal mode. To run this command, enter the name and password of CLI super administrator account admin as prompted.
  13. Check the system status.

    On SmartKit, choose Home > Storage > Routine Maintenance > More > Inspection and check the system status.
    • If all inspection items pass the inspection, the inspection is successful.
    • If some inspection items fail, the inspection fails. Rectify the faults by taking recommended actions in the inspection reports. Perform inspection again after fault rectification. If the inspection still fails, contact Huawei technical support.

    For details, see the FusionStorage Block Storage Administrator Guide.

Follow-up Procedure

Label the replaced SSD card to facilitate subsequent operations.
