Format Thin Provisioning Pool (Unformatted Area)

Overview

This function formats unformatted areas in the Thin Provisioning Pool (TPP).

Caution
  • This function cannot be used under the following conditions:

    • No TPPs can be formatted

    • The status of the TPPs that are to be formatted is "Available"

    • The TPP includes a volume that is used for the Storage Cluster function

  • If the error message "An internal resource is insufficient." appears after TPPs are formatted, a format of TPPs may have failed. Check the "Status" of the formatted TPPs in the [Thin Provisioning Pool] screen. Refer to the [Thin Provisioning Pool (Basic Information)] function for details. TPPs in the "Readying" or "Partially Readying" state have not been formatted. Perform either of the following procedures according to the status.

    • For the "Readying" state, wait until the current formatting process is completed and then use the [Format Thin Provisioning Pool (All Area)] function to reformat the relevant TPPs.

    • For the "Partially Readying" state, wait until the current formatting process is completed and then use this function to reformat the relevant TPPs.

Note

  • TPPs with the status of "Partially Readying" or "Readying" can be formatted. Even if formatting is performed, the data that is stored in the TPVs of the target TPP is not deleted. The "Unformatted area" is a new area that is added to a TPP by the capacity expansion function.

  • This function is only used when an error occurs during TPP capacity expansion and the expanded area cannot be formatted. When TPP capacity is successfully expanded, the TPP is automatically formatted. In this case, it is not necessary to format the TPP by using this function.

  • Progress of formatting ("Progress", "Estimated Time Left", and "Remaining Size") can be checked in the [Thin Provisioning Pool (Basic Information)] function. Click the TPP name to display the basic information.
