Table 1. Basic HyperSwap commands
Command Action
HyperSwap Triggers a HyperSwap where I/O is redirected from the source volume to the target volume, without affecting the application using those volumes. You can use this command if you want to perform maintenance on the original source volumes.
Refresh States

Refreshes the states of the role pairs that are in the session (if applicable for the session type) and refreshes the state of the session if it is incorrect. This command queries the states of the copy sets on the hardware. You are not required to run this command under typical circumstances; Copy Services Manager refreshes the states of its sessions through multiple means. However, if you discover an inconsistency between Copy Services Manager and the hardware, you can use this command to enable Copy Services Manager to update itself.

This command triggers multiple queries on the hardware, which can impact hardware performance. Do not run this command more frequently than every few minutes in each session.

This command is not available if the session is in the Defined state.
Start H1->H2 Starts copying data synchronously from H1 to H2 in a Metro Mirror session.
Note: A session might go into a Severe state with error code 1000000 before the session returns to Normal/Prepared State and HyperSwap Capable. The duration of the Severe state depends on how large of a session is running.
Start H2->H1 Starts copying data synchronously from H2 to H1 in a Metro Mirror session. You can issue this command only after the session has been swapped and the production site is H2. To enable data protection when the H1 volumes are available again, start I/O to the H2 volumes, and issue this command to replicate data from the H2 volumes to H1 volumes.
Stop Suspends updates to all the targets of pairs in a session. You can issue this command at any time during an active session.
Note: After you issue the stop command, targets might not be consistent.
Terminate Removes all physical copies and relationships from the hardware during an active session.
