Managing vFlash SD Card

vFlash service is a licensed feature. The vFlash SD card is a Secure Digital (SD) card that plugs into the vFlash SD card

slot on the managed system. You can use a card with a maximum of 16 GB capacity. After you insert the card, you must

also enable vFlash service to create and manage partitions.

For more information on the vFlash SD card, see the Persistent Storage ProfilePersistent Storage Profile.

Displaying Inventory of vFlash SD Card

Perform the Enumerate operation on the DCIM_VFlashView class to display all the properties of the vFlash SD card,

such as:

• Available size

• Capacity

• Licensed

• Health

• Enable or disable state

• Initialized state

• Write-protected state.

Displaying Partitions on vFlash SD Card

Perform the Enumerate operation on the DCIM_OpaqueManagementData class to display all the partitions and their

properties, such as partition ID, its size, and data format.

Creating and Modifying Partitions on vFlash SD Card

To create and modify partitions on a vFlash SD card:

1. Perform the enumerate operation on the DCIM_OpaqueManagementData class to get the list of current

partitions.

2. Before you invoke the CreatePartition() or CreatePartitionUsingImage() method on

DCIM_PersistentStorageService class, construct the input parameters.

3. Invoke the CreatePartitionUsingImage() method to form a bootable image. This creates a bootable partition from

image stored on server shares such as NFS, CIFS, and FTP. Alternatively, invoke CreatePartitionUsingImage() to

create a bootable partition from an ISO image.

If a job is created successfully, code 4096 is returned.

4. Query the status of the job ID output using the job control profile methods.

5. Repeat step 1 to confirm successful execution of the method.

6. Invoke the ModifyPartition() method to change the access type of the partition to Read-Only or Read-Write.
