1. A method comprising:
- determining, by a first network device, that the first network device is ready to apply a volume hierarchy, wherein determining that the first network device is ready includes performing one or more sanity checks on the volume hierarchy;
sending, by the first network device, a notification message to at least one other network device, wherein the notification message indicates that the first network device is ready to apply the volume hierarchy;
receiving a command at the first network device to apply the volume hierarchy, wherein the command indicates that one or more other network devices are also ready to apply the volume hierarchy, wherein the command is received from a second network device in response to receiving the notification message from the first network device; and
applying the volume hierarchy at the first network device so that the first network device processes input/outputs (IOs) using the volume hierarchy.

Abstract
In one embodiment, a solution is provided wherein a volume hierarchy may be received at a network device in a storage area network. Once the network device is ready to apply the volume hierarchy, a message so indicating may be sent. Later, a command to apply the volume hierarchy may be received and the volume hierarchy may be applied so that the network device processes IOs using the volume hierarchy.

15. An apparatus comprising:
-
a processor; and a memory, wherein at least one of the processor or the memory is adapted for; determining, by a first network device, that the first network device is ready to apply a volume hierarchy, wherein determining that the first network device is ready includes performing one or more sanity checks on the volume hierarchy; sending, by the first network device, a notification message to at least one other network device, wherein the notification message indicates that the first network device is ready to apply the volume hierarchy; receiving a command at the first network device to apply the volume hierarchy, wherein the command indicates that one or more other network devices are also ready to apply the volume hierarchy, wherein the command is received from a second network device in response to receiving the notification message from the first network device; and applying the volume hierarchy at the first network device so that the first network device processes input/outputs (IOs) using the volume hierarchy. - View Dependent Claims (16)
