Apply Configuration

Overview

This function applies the configuration information to the storage system.

The following configuration information can be applied.

  • The configuration file that is obtained by the [Export Configuration] function

  • "1 time before", "2 times before", or the "Latest" configuration information stored in the storage system

  • The backup file stored in the Bootup and Utility Device (BUD) of the CM using the [Backup Configuration] function.

"Configuration (1 time before)" and "Configuration (2 times before)" are updated when applying the configuration information using this function. "Configuration (Latest)" is updated when this function is executed and then applied to the storage system.

Caution

  • Do not use this function during host access.

  • The storage system must be rebooted after this function is executed. Any setting processes cannot be performed until the applied configuration information is enabled by rebooting the storage system.

  • If this function is used while the Advanced Copy function is used, the copy session information is deleted after a reboot even if the copy session is in the "Active" or "Suspend" state.

    In this case, ask your system administrator to recreate the copy sessions and perform the initial copy process of REC.

  • Do not use this function when using functions that modify the configuration (e.g. RAID migration) or functions that change data (e.g. format).

  • Do not use this function during rebuild, copy back, or redundant copy operation.

  • This function cannot be used under the following conditions:

    • No configuration file is selected

    • No data exists in the configuration file

    • An error exists with the configuration file size

    • An error exists in the configuration file

  • The configuration information cannot be applied in the following conditions:

    • The storage system model does not match the model in the configuration information

    • Snap Data Volume (SDV), Snap Data Pool Volume (SDPV), or REC Disk Buffer is specified in the configuration information even though the Advanced Copy function license has not been registered in the storage system

    • Thin Provisioning Pool (TPP) or Thin Provisioning Volume (TPV) is specified in the configuration information even though the Thin Provisioning function has been disabled for the storage system

    • Encrypted volume or encrypted TPP is specified in the configuration information even though the "Encryption Mode" has been disabled for the storage system

    • The REC disk buffer information for the associated REC buffer in the configuration information does not match the actual storage system configuration

    • The volume encryption status (encryption by CM/unencrypted) in the configuration information does not match the actual storage system configuration (Restore mode selected)

    • The Thin Provisioning configuration in the configuration information does not match the actual storage system configuration (Restore mode selected)

      [Example]

      • TPP (Thin Provisioning Pool): The drive type or number of drives does not match

      • TPV (Thin Provisioning Volume): The TPP number does not match

      • FTRP (Flexible Tier Pool): The drive type or number of drives does not match

      • FTSP (Flexible Tier Sub Pool): The drive type or number of drives does not match

      • FTV (Flexible Tier Volume): The FTRP number does not match

    • The SDP capacity in the configuration information exceeds the maximum SDP capacity of the storage system

    • The TPP capacity in the configuration information exceeds the maximum TPP capacity of the storage system

    • The configuration information contains a CM that is failed in the actual storage system

    • The configuration information includes unknown parameters

  • If "Initialize" is selected for the Apply Mode, formatting of all the volumes is required after rebooting the storage system.

  • If "Initialize" is selected for the Apply Mode, formatting of all TPP and all TPV is required after rebooting the storage system.

  • Do not use this function if different RAID groups are registered in the key group of the storage system and the configuration information. If the configuration information is applied under these circumstances, the status of the SEDs that configure the relevant RAID group changes to "Broken". The RAID groups that are registered in the key group can be checked by using the "SED Key Group" screen.

Note

  • When an incorrect apply mode is selected or the wrong configuration information is specified, use the [Cancel Applying Configuration] function to cancel the [Apply Configuration] process before rebooting the storage system. The [Cancel Applying Configuration] function is only available when the [Apply Configuration] function has been executed but the storage system has not been rebooted yet.
