With ESI, you can expand host disks that meet the following criteria:
The disk has only one volume. The volume can be expanded if the host is connected.
The disk has an associated LUN that can either be expanded or is a file-based disk which is supported by VMware.
Note: With VMware systems, ESI does not support expanding RDM disks that are attached with virtual compatibility mode.
To expand disks in ESI:
In the left pane of the ESI window, select the host.
In the center pane, click Host Disk, and then select a disk from the list.
From the menu bar, select Action > Expand Disk.
In the New Disk Capacity page, type the new capacity for the disk, select a unit of measurement, and then click Next.
Note: For example, change the disk capacity from 3 GB to 4 GB.
In the Review Input Parameters page, review the settings, and then click Next to confirm them.
In the Progress page, click Next.
Note: Click More Information for more progress details. If a problem occurs while you are expanding a disk, an error message appears along with options to resume or roll back the process. After the error is resolved, click Resume to resume the process. Click Rollback to revert to the previously executed step.
In the Summary
page, click Finish.
The expanded storage capacity for the disk will display in the Host Disks tab.
