Identifying Storage Devices
This section explains how to identify and configure storage devices after they arrive at the site.
- Storage devices are debugged before delivery. If multiple sets of storage devices are delivered, ensure that each set is installed in the correct system and that devices are not mixed up.
- Upon arrival, devices are identified by their packing list number (P/L No.) shown on the outer carton. The P/L No. is the same for devices in the same set. The packing list count (Site Count) indicates the number and ID of the devices.
Before unpacking goods, identify different sets of storage devices and store them separately to prevent device mix-up from causing a system failure.
Figure 4-40 shows the P/L No. and Site Count on the outer carton.
- If the same set of storage devices use multiple controller enclosures, for easier maintenance, management, and future capacity expansion, devices are installed in a customer-supplied bay in the same way as in a Huawei bay. To identify the storage devices, use the following methods:
- Controller enclosure: On top of the controller enclosure you can find its ID, which indicates the bay the controller enclosure belongs to. If the controller enclosure ID is CTE0, the controller enclosure belongs to system bay 0. CTE represents a controller in a system bay, CTE0 represents a controller in system bay 0, CTE1 a controller in system bay 1, and so on.
- Disk enclosure: A disk enclosure ID is labeled on a disk enclosure's expansion modules. It indicates which controller enclosure manages the disk enclosure. In DAEXYZ-M, DAE indicates a disk enclosure, X the system bay ID, Y the disk enclosure loop ID, Z the enclosure ID in the disk enclosure loop, and M the disk enclosure's expansion module. For example, DAE000–B indicates expansion module B in disk enclosure 0, which is in disk enclosure loop 0 of system bay 0. Configure disk enclosures based on these configuration principles (this does not include disk enclosures with configuration disks).
- Labels may be either blank or printed. Printed ones are pasted on to cables, whereas blank ones are placed in an auxiliary material bag.
- The two layout diagrams are in an auxiliary material bag and users can paste them on the cabinet door or controller enclosure according to the device layout. For details about how to use layout diagrams to determine the maximum number of cascaded disk enclosures in a loop, see Follow-up Procedure.
