1. A method for supporting subnet management in a network environment, comprising:
- providing a first switch and a second switch in a subnet, wherein the second switch includes a subnet manager in a dry-run mode, and wherein the first switch is associated with a set of disabled secret keys, wherein the set of disabled secret keys causes the first switch to be inactivated from the perspective of the second switch;
performing, via the subnet manager of the second switch, one or more dry-run operations, wherein the one or more dry-run operations includeat least one operation configured to initialize the first switch by providing configuration and policy information for each port in the first switch, andat least one operation configured to determine that the subnet has required properties and connectivity; and
activating the first switch by enabling the set of disabled secret keys, in response to the subnet manager that has determined that the subnet has the required properties and connectivity.

Abstract
A system and method can support subnet management in a network environment. One or more inactivated switches can be included in a subnet, wherein each of the inactivated switches is associated with an empty set of known secret keys. A subnet manager (SM) in a dry-run mode can perform one or more dry-run operations on the one or more inactivated switches, before activating the one or more inactivated switches.

10. A system for supporting subnet management in a network environment, comprising:
-
one or more microprocessors; a subnet manager, running on the one or more microprocessors, wherein the subnet manager operates to provide a first switch and a second switch in an activated subnet, wherein the second switch includes a subnet manager in a dry-run mode, and wherein the first switch is associated with a set of disabled secret keys, wherein the set of disabled secret keys causes the first switch to be inactivated from the perspective of the second switch, perform, via the subnet manager of the second switch, one or more dry-run operations, wherein the one or more dry-run operations include at least one operation configured to initialize the first switch by providing configuration and policy information for each port in the first switch, and at least one operation configured to determine that the subnet has required properties and connectivity, and activate the first switch by enabling the set of disabled secret keys, in response to the subnet manager that has determined that the subnet has the required properties and connectivity. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A non-transitory machine readable storage medium having instructions stored thereon that when executed cause a system to perform the steps comprising:
-
providing a first switch and a second switch in a subnet, wherein the second switch includes a subnet manager in a dry-run mode, and wherein the first switch is associated with a set of disabled secret keys, wherein the set of disabled secret keys causes the first switch to be inactivated from the perspective of the second switch; performing, via the subnet manager of the second switch, one or more dry-run operations, wherein the one or more dry-run operations include at least one operation configured to initialize the first switch by providing configuration and policy information for each port in the first switch, and at least one operation configured to determine that the subnet has required properties and connectivity; and activating the first switch by enabling the set of disabled secret keys, in response to the subnet manager that has determined that the subnet has the required properties and connectivity.
