ABSTRACT:
Provided are a method, system, and article of manufacture for copying writes from primary storages to secondary storages across different networks. A failure notification is communicated, using a first network protocol, from a primary device in a first group of at least one primary device and at least one corresponding primary storage managed by the at least one primary device to a control system in response to the primary device determining that a write to the primary storage cannot be copied to a corresponding secondary storage. A failure notification is communicated, using a second network protocol, from a primary device in a second group of at least one primary device and at least one corresponding primary storage managed by the at least one primary device to the control system in response to the primary device determining that a write to the corresponding primary storage cannot be copied to a corresponding secondary storage. A freeze command is received, from the control system using the first network protocol at the at least one primary device in the first group. A freeze command is received, from the control system using the second network protocol at the at least one primary device in the second group. The copying of writes from the primary storages in the first and second groups to the corresponding secondary storages is suspended in response to receiving the freeze commands.
