Checking the UltraPath Status

0xF00150019 No Redundant Link Between the Host and a Storage Array

  1. Check whether the host is connected to only one controller of the storage array through cables.

    • If yes, connect the host to multiple controllers. If the alarm persists, go to step 2.
    • If no, go to step 2.

  2. On the CLI, run the show initiator command to check whether the WWN of the initiator and the Host ID are consistent with the actual condition.

    NOTE:
    The preceding figure shows that both initiators are added to the host and correctly configured in a dual-controller scenario.
    • If yes, go to step 4.
    • If no, go to step 3.

  3. On the CLI, run the show initiator command to check whether only some of the initiators are in the host.

    NOTE:
    The preceding figure shows that the WWN of the initiators is inconsistent with the Host ID and one initiator is not added to the host whose Host ID is 0.
    • If yes, run the add host initiator host_id=0 initiator_type=FC wwn=100000053326e259 command to add the remaining initiators to the host. Then, go to step 4.

      NOTE:
      The preceding figure shows how to run the add host initiator host_id=0 initiator_type=FC wwn=100000053326e259 command to add remaining initiators to the host on the CLI.
    • If no, go to step 5.

  4. Scan for disks on the host and confirm that the number of detected disks is correct. Then check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to step 5.

  5. Collect related information and contact technical support engineers.

0xF0015001A A Link Fault Between the Host and a Storage Array

  1. Check whether any cable connected between the host and the storage array is removed.

0xF00150025 Paths Between The Host And Storage Array Do Not Meet Redundancy Requirements

  1. Find the host whose Health Status is No redundant link, and check whether the interface modules connected to the host meet redundancy requirements. (The host is connected to ports on controllers in both slot A and slot B.)

    • If yes => 2。
    • If no => ensure that the interface modules connected to the host meet redundancy requirements. This alarm is cleared and the Health Status field is updated when the status of all controllers is normal. The clearing and update have a delay subject to the service scale. If the alarm persists, go to step 2.

  2. Check whether the interface modules that house member ports in the port group mapped to the host meet redundancy requirements. (The ports are on controllers in both slot A and slot B.)
    • If yes => 3。
    • If no => ensure that the interface modules that house member ports in the port group mapped to the host meet redundancy requirements. If the alarm persists, go to step 3.

  3. Collect related information and contact technical support engineers.

0xF00150034 The Host Has No Redundant Links To The Storage Array

  1. Check whether the host is connected to only one controller on the storage array.

  2. Check whether initiators configured for the host are consistent with the actual condition.

    • If yes => 3.
    • If no => add all initiators to the host based on the actual condition. If the alarm persists, go to step 3.

  3. Scan for disks on the host and confirm that the number of detected disks is correct. Check whether the alarm is cleared.

    • If yes => no further action is required.
    • If no => 4.
    • If the storage array cannot connect to the host any more, for example, the host mapping is permanently deleted or the host is permanently faulty, this alarm needs to be manually cleared.

  4. Collect related information and contact technical support engineers.
