Remove Channel Adapter

Overview

This function removes a Channel Adapter (CA) while the storage system is operating.

After isolation of the CA to be removed and the controller module (CM) in which the CA is installed, the CA is removed from the storage system.

Caution

  • Perform the start maintenance operation by using the [Start/End Maintenance] function before the removing task. If the operation has not been performed, the removal cannot be started.

  • Only one CA can be removed at a time.

  • For 1CM model, the [Finish] screen is displayed without executing isolation of the CM. Remove the CA according to the displayed procedure. (For the ETERNUS DX100 S5/DX200 S5)

  • This function cannot be used under the following conditions:

    • The status of the CA that is to be removed or the CM to which the target CA belongs is not normal

    • Storage Migration paths are set for the CA that is to be removed

    • No CAs are installed

      (including when the NAS-CAs are installed in the storage system that is not part of a Unified Storage environment)

    • A CM-FC (CM with direct mount CA) has been installed in the ETERNUS DX100 S5 and "CA#0" is selected

    • The port for the CA that is to be removed is used for the Storage Cluster function

    • When removing a NAS-CA and the CA port is being used by the multipath configuration

    • When removing a NAS-CA and the CA port is being used by the Bonding configuration

    • When removing a NAS-CA and the CA port is being used by the NAS interface configuration

    • The CA that is to be removed is directly mounted in the CM (for the ETERNUS DX60 S5)

Note
