What Should I Do If the Disk of a Windows ECS Becomes Offline After the ECS Specifications Are Modified?

Scenarios

After the specifications of a Windows ECS were modified, disk attachment may fail. Therefore, check disk attachment after specifications modification. This section describes how to check disk attachment after ECS specifications are modified.

Procedure

  1. Check whether the number of disks displayed on the Computer page after specifications modification is the same as that before specifications modification.
    • If yes, the disks are properly attached. No further action is required.
    • If no, an error has occurred in disk attachment. In such a case, go to step 2.

    For example:

    An ECS running Windows Server 2008 has one system disk and two data disks attached before specifications modification.

    After the specifications are modified, check disk attachment.

    Only one system disk is displayed. Data disks failed to attach after the specifications modification.

  2. Set the affected disks to be online.
    1. Click Start in the task bar. In the displayed Start menu, right-click Computer and choose Manage from the shortcut menu.

      The Server Manager page is displayed.

    2. In the navigation pane on the left, choose Storage > Disk Management.

      The Disk Management page is displayed.

    3. In the left pane, the disk list is displayed. Right-click the affected disk and choose Online from the shortcut menu to make it online.
