Format Flexible Tier Pool (Unformatted Area)

Overview

This function formats unformatted areas in the Flexible Tier Pool (FTRP).

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

    • No FTSPs are registered in the FTRP

    • No FTRPs can be formatted

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

    • Shrinking is being performed in the FTRP

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

    • The FTRP includes a volume that is used for the Virtual Volume function

  • If the error message "An internal resource is insufficient." appears after FTRPs are formatted, a format of FTRPs may have failed. Check the "Status" of the formatted FTRPs in the [Flexible Tier Pool] screen. Refer to the [Flexible Tier Pool (Basic Information)] function for details. FTRPs 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 Flexible Tier Pool (All Area)] function to reformat the relevant FTRPs.

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

Note

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

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

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