Checking Disk Domain Status

Checking Disk Domain Status

By checking the status of a disk domain, you can understand its health status, operating status, total capacity, and used capacity. The operating status of a disk domain directly affects that of a storage pool.


Log in to DeviceManager as a read-only user.


  1. Go to the Disk Domain page.
    1. In the navigation tree on the right, click Provisioning.
      The Provisioning page is displayed.
    2. Click Disk Domain.
      Go to the Disk Domain page.
  2. Check disk domain status.
    1. On the Disk Domain page, check Health Status and Running Status of disk domains to ensure that all disk domains are working correctly. If an alarm is displayed, handle it in time based on the alarm information.

      • For details, click next to the table heading. From the drop-down list, select indicators you are concerned with.
      • If the free capacity of a disk domain is insufficient, expand the disk domain within the licensed capacity limit to ensure that the storage pools and LUNs in the disk domain provide adequate storage space.

    2. If you select a disk domain, the bottom area shows details about its capacity distribution and contained storage pools and disks.

      You can also view the task progress of the disk domain you have selected. Click Properties, click the General tab in the dialog box that is displayed, and view the progress of Precopy, Reconstruction, and Balancing in the Progress area.
