Removing and replacing a boot drive: 2145-SV2 and 2145-SA2

Use this procedure to remove and replace a faulty boot drive from a node canister.

About this task

The node canister has dual boot drives. The system can run if one boot drive fails. Before you remove or power off the node, verify whether any volumes depend on the enclosure.

Notes:
  • If both boot drives in a node canister are replaced with new drives, then some Ethernet configuration of the node will be lost, such as the service IP and node IP. Use the Service Assistant Tool to reset the service IP and node IP if needed. (A node IP is only needed if the node must communicate with other nodes by using RDMA over Ethernet.)
  • No tools are required to complete this task. Do not remove or loosen any screws while you are completing this procedure.

Procedure

  1. Review the Event Log to identify the faulty boot drive.
    Record the drive number and FRU Identity value of the drive.
  2. Use the management GUI to determine the status of the node canister.
  3. Record which cables are plugged into the specific ports on the rear of the node canister. The cables must be inserted back into the same ports after the replacement is complete; otherwise, the system cannot function properly.
  4. Disconnect the data and power cables that are connected to the node canister.

Removing the boot drive

  1. Remove the node canister, as described in Removing and replacing the node canister in the node: 2145-SV2 and 2145-SA2.
  2. Remove the cover, as described in Removing and replacing the cover of the canister: 2145-SV2 and 2145-SA2.
  3. Locate the faulty boot drive.
    Refer to Figure 1 and find the boot drive slot matching the slot ID recorded earlier.
    • Slot 1 is nearest the fans
    • Slot 2 is nearest the PCIe adapters
    You should also confirm that the serial number on the drive matches the FRU Identity value recorded in step 1. The serial number begins with "11S" and has 22 characters.

  4. Gently open the blue friction latch, as shown in Figure 2. Apply gentle pressure; do not force the latch open.

    When released, the boot drive pops up approximately 30 degrees. You can then carefully slide it out of connector.

Replacing the boot drive

  1. Hold the new boot drive at a 25 degree angle, as shown in Figure 1. Then, gently slide the drive into the connector until it stops.

    The contacts on the end of the boot drive will be fully covered. The boot drive is then hinged at the connector at one end and pressed down behind a friction clip at the other end.

  2. Replace the node canister cover, as described in Removing and replacing the cover of the canister: 2145-SV2 and 2145-SA2.
  3. Reinsert the node canister, as described in Removing and replacing the node canister in the node: 2145-SV2 and 2145-SA2.
  4. Reconnect the power and connection cables to the node canister, ensuring that each cable goes into the same port from which it was removed.
  5. Use the management GUI or service assistant to check the status of the node canister.
