Controller enclosure power indicator during OS boot → Blinking green at 2 Hz; Disk module location indicator → Blinking yellow at 2 Hz; Controller enclosure location indicator → Blinking blue at 2 Hz; Controller enclosure major/critical alarm indicator → Steady yellow

Hardware indicators provide a direct physical diagnostic mechanism during OceanProtect maintenance. The four states represent different operational meanings rather than interchangeable fault conditions.

A blinking green power indicator at 2 Hz represents the controller enclosure progressing through its boot process. A blinking yellow disk-location indicator at 2 Hz identifies the specific disk selected for physical location. A blinking blue enclosure-location indicator at 2 Hz similarly helps maintenance personnel identify the correct controller enclosure in a rack. A steady yellow alarm indicator identifies a major or critical alarm condition requiring investigation.

Huawei emphasizes that abnormal hardware indicators are a primary method for locating failing FRUs and CRUs and should be correlated with DeviceManager alarm information. The OceanProtect X6000/X8000 architecture also uses redundant, serviceable hardware components, including controllers, BBUs, power supplies, and interface modules, making correct physical fault identification essential during maintenance.

Huawei states: “LUN information exchange refers to the mapping between LUNs and data volumes. That is, when the LUN IDs of the source LUN and target LUN remain unchanged, the data volume IDs of the source data volume and target data volume are exchanged.”

Therefore, A, B, C, and D are all correct.

Before the exchange, the source LUN ID points to its original source data volume, which validates C. During the information exchange, the logical LUN identifiers remain stable but their associated physical data-volume IDs are exchanged, validating D. Consequently, after the exchange, the source LUN ID—the identity already known by the host—now references the target data volume, validating A.

During synchronization before the swap, SmartMigration uses dual-write and DCL technologies to keep the target LUN consistent while host services continue. Once synchronization is complete, space is exchanged and the migration relationship is interrupted/split. At that stage, normal host writes continue against the migrated target data rather than maintaining the previous dual-write synchronization relationship, which validates B.
