You perform some maintenance tasks in response to conditions discovered
during system monitoring, you can change certain settings as needed to meet changing
operational requirements, and you can perform different tasks on pairs in day to day
operations as a Storage Administrator.
Pair operations cannot be performed when changing the firmware, nor if firmware changes are cancelled. If you start a firmware change, make sure it is complete before performing pair operations. An exception is that you can perform pair operations from CCI even while changing the firmware or when firmware changes are canceled. If you want to use a volume connected to a host with NVMe/TCP, specify the paired volume in the dummy LU. For more information, see the Command Control Interface User and Reference Guide.
