In order to improve the performance and reliability of its core business, a company configured the SmartEqualizer feature in its data storage system. In the process of configuring the address pool, which of the following descriptions about the number of addresses in the IP address segment is correct?
- A . Up to 1024
- B . Up to 512
- C . Up to 2048
- D . Up to 256
A company has purchased multiple Huawei OceanStor Pacific series devices to deploy the remote replication service. During routine operation and maintenance, an administrator needs to manage the replication cluster.
Which of the following statements are true about a replication cluster?
- A . Capacity reduction of a replication cluster can be performed only when the number of nodes is greater than or equal to 4.
- B . The name of a replication cluster for which cross-site disaster recovery is enabled cannot be changed, but the replication cluster can be deleted.
- C . When the capacity of a replication cluster is expanded, the replication network can share the same subnet with other networks.
- D . When an IP address of a replication cluster is changed, if a node in the replication cluster uses multiple ports and different replication ports are configured with IP addresses in the same network segment, the original policy-based route must be deleted before configuring a new policy-based route.
A,D
Explanation:
A is true. Huawei’s replication-cluster management documentation states that for capacity reduction, the number of nodes to be removed from a replication cluster must be greater than or equal to 4. This matches the intent of the statement.
B is false. Huawei provides a Change Nameoperation for replication clusters, which shows that the replication cluster name can be changed. Therefore, the statement saying the name cannot be changed is incorrect.
C is false. Huawei states that the replication network cannot use the same subnet as other networks, and the replication network also does not share network ports with other networks. Therefore, saying it can share the same subnet is incorrect.
D is true. Huawei’s documentation for changing a replication cluster IP address states that when different replication ports on the same node use IP addresses in the same network segment, the original policy-based route must be deleted before a new policy-based route is configured.
An engineer found that the FC host port of the flash storage was abnormal on the DeviceManager interface. After browsing the relevant information, he found that the health status of the port was "–" and the operation status was not connected. Then he went to the equipment site and found that the link indicator of the FC host port was red.
Which of the following reasons may be the cause? (Multiple choice)
- A . The optical module is faulty.
- B . The latest SP patch is not installed in the Windows host operating system
- C . The iscSI host port IP address is configured wrongly
- D . The host port optical module type does not match
Huawei flash storage can support () expansion mode, that is, using the existing storage system to meet the growing needs of customers by continuously adding storage devices.
A government customer purchased a Huawei OceanStorDorado storage system for business deployment.
During routine maintenance, an engineer discovered that the health status of the storage pool was degraded.
Which of the following descriptions is correct?
- A . The health status of the storage pool is degraded, which means that the storage pool can work normally, but cannot achieve optimal performance.
- B . The health status of the storage pool is degraded, which means that the storage pool cannot work properly.
- C . The health status is equivalent to the running status, so the storage device has stopped running and cannot provide space.
- D . All subsequent LUNs created from this storage pool are in write-protected state, meaning that the business can only read the LUN but cannot write to it.
According to the severity and impact of the fault, storage system faults can be divided into three levels: common faults, () faults and severe faults.
Assume an Industry customer purchased a Huawel flash storage device for service deployment. After a fault occurs, an engineer needs to use the CLI to view bit error Information of front end host ports for troubleshooting.
Which of the following commands cannot be used for this purpose?
- A . show coexist-forward-switch
- B . show controller io io_type=frontEnd controller_id=XX
- C . show port biLerror
- D . show host-port error
In the DeviceManager management interface, engineers can view the corresponding fault level through "Current Alarm".
Which of the following items belong to the fault information level included in "Current Alarm"? (Multiple choice)
- A . Emergency
- B . Important
- C . Tips
- D . Warning
() uses Huawei’s optimized Flex EC algorithm, which allows the system to tolerate three disk failures at the same time, which can greatly shorten the reconstruction time and effectively cope with the data protection challenges in the era of large disks.
In actual business scenarios, the active-active system of Huawei’s OceanStorPacific series products can support incremental synchronization. When a site fails, the site that wins the arbitration will provide services according to the arbitration mechanism, and IO requests will be converted from dual write to single write. When the failed site recovers the system, it can support the ability to synchronize the data of the failure process to the recovery site.
- A . True
- B . False
