Storage control session states

The following states apply to the XRC storage control sessions for a primary volume in an XRC session.
Session state . . . Description . . .
Quiesced A non-ESS storage control session is in quiesced state after an XSUSPEND command has completed. The session remains quiesced until either you issue an XSTART command and the storage control session becomes active, or the quiesce timeout condition expires and the storage control session ends.
Suspended storage control session An ESS storage control session is in a suspended state after either receiving a system reset or when the XRC session becomes suspended. When XRC stops reading from the ESS, the ESS suspends the storage control session. The session remains suspended until you issue an XADDPAIR command for a volume that is associated with the storage control session.
Active The state in which normal mirroring is done.
Terminated The session has ended.
