Format Flexible Tier Pool (All Area)

Overview

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

Caution

  • When formatting all areas in an FTRP, data stored in the FTVs in the FTRP will be deleted. Format FTV to use them again when data in FTV is deleted.

  • An FTRP cannot be formatted if data migration with the Flexible Tier function is being performed on one of its FTVs. Start FTRP formatting after the data migration is complete.

  • An error will stop the RAID migration when an FTRP, in which the currently migrating FTV belongs, is formatted. Stop the RAID migration session or wait until the RAID migration session is complete, and then format the FTRP.

  • When an FTRP that is being balanced is formatted, an error occurs and the FTRP balancing session is stopped. Stop the FTRP balancing session or wait until the FTRP balancing session is complete, and then format the FTRP.

  • This function cannot be used under the following conditions:

    • No FTSPs are registered in the FTRP

    • No FTRPs can be formatted

    • 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 this function to reformat the relevant FTRPs.

    • For the "Partially Readying" state, wait until the current formatting process is completed and then use the [Format Flexible Tier Pool (Unformatted Area)] function to reformat the relevant FTRPs.

Note

  • FTRPs with the status of "Available", "Partially Readying", "Readying" or "Exposed" can be formatted.

  • 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.

  • To format FTVs, use the [Format Volume] function.

  • When an FTRP is created using the ETERNUS SF Storage Cruiser, the FTRP is formatted automatically. In this case, it is not necessary to format the FTRP by using this function.
