In Huawei OceanStor 9000, a node pool is a collection of nodes that have the same characteristics such as physical type and access performance, and dynamic storage tiering allows a user to group physical nodes in the same file system into different node pools.
Huawei hyper-converged storage supports parallel and fast data reconstruction. Data is fragmented in the resource pool. A disk failure triggers automatic and parallel reconstruction of the actual data by the entire resource pool without requiring hot spare disks.
Logical ports are created on physical Ethernet ports, bound ports, or VLANs for service operations. A home port must be specified. If the home port fails, services will fail over to another functioning port.
The persistence layer of Huawei distributed storage provides persistent storage, EC, and multi-copy capabilities. Plog Client provides the append only plog access.
In Huawei distributed storage systems, the asynchronous remote replication architecture of the block service establishes an asynchronous remote replication relationship based on a block service cluster. This architecture also synchronizes data between primary and secondary volumes based on differential data. All the data generated on the primary volume after the last synchronization will be written to the secondary volume in the next synchronization.
A service host is connected to a storage device through Fibre Channel SAN. However, the service host cannot detect mapped LUNs after scanning. Which of the following are possible causes?
