OceanStor 5300 V3, 5500 V3, 5600 V3, 5800 V3, and 6800 V3 Storage System V300R003

Routine maintenance activities are the most common activities for the storage device, including powering on or off the storage device, managing users, modifying basic parameters of the storage device, and managing hardware components. This document applies to the system administrators who are responsible for carrying out routine maintenance activities, monitoring the storage device, and rectifying common device faults.

Making Storage Space Available (VMware)

Making Storage Space Available (VMware)

This section uses a VMware ESXi.5.1.0 application server and datastores based on VMFS-5 file system configuration as an example to introduce how to make the storage space available to a VMware-based application server. For application servers running other versions of VMware operating systems, adjust the operations based on actual conditions.

Context

You can use any of the following methods to make the storage space available to a VMware-based application server:
  • Device-based method

    After a mapped device is detected on the application server, use the device to configure disks for a VM.

  • Datastore-based method

    After a mapped device is detected on the application server, create a corresponding file system and use the storage space. Datastore is a common method to help you use the storage space.

Procedure

  1. Optional: Configure the multipathing software information.

    The VMware system has its own multipathing software NMP. You can directly use this software without the need to configure it. If you use UltraPath, see your UltraPath document.

    For details about the recommended configurations when using NMP, see Huawei SAN Storage Host Connectivity Guide for VMware ESXi.

  2. Go to the Add Storage dialog box.
    1. On the vSphere Client, click the Configuration tab.
    2. On the navigation bar, click Storage.
    3. On the Storage page, click the Devices tab and click Rescan All.

      The Rescan dialog box is displayed, as shown in Figure 4-12.

    4. Click OK.

      It takes 2 to 4 minutes to scan for new storage devices and virtual machine file system (VMFS) volumes. You can check the task status in the Recent Tasks area at the lower part of the main window.
      • If the task status is In Progress as shown in Figure 4-13, the scanning is ongoing.
        Figure 4-13  Scanning ongoing

      • If the task status is Completed as shown in Figure 4-14, the scanning is completed.
        Figure 4-14  Scanning completed

    5. On the Storage page, click the Datastores tab and click Add Storage.

      The Add Storage dialog box is displayed, as shown in Figure 4-15.

  3. Configure datastore parameters.
    1. Select Disk/LUN for Storage Type and click Next.
    2. Select the LUN mapped from the storage system and click Next, as shown in Figure 4-16.

      NOTE:
      • If multiple LUNs appear on the interface, you can distinguish them from each other by WWN.
      • To query the WWN of a LUN on the DeviceManager, choose Resource Allocation > View and Management > LUNs.

    3. Select VMFS-5 for File System Version and click Next.
    4. Confirm the disk layout and click Next.
    5. Enter a name for the datastore and click Next.
    6. Configure the disk capacity and click Next, as shown in Figure 4-17. In normal cases, configure the maximum available space.

  4. Confirm the configurations and click OK.

    It takes 3 to 5 minutes to create a datastore. You can check the task status in the Recent Tasks area at the lower part of the main window.
    • If the task status is In Progress, the datastore is being created.
    • If the task status is Completed, the datastore has been created.

Result

  • On the Datastores tab page, you can view the newly configured datastores, as shown in Figure 4-18.

  • On the Devices tab page, you can view the newly scanned devices, as shown in Figure 4-19.
