VOLUME HIERARCHY DOWNLOAD IN A STORAGE AREA NETWORK
First Claim
Patent Images
1. A method comprising:
- determining by a first network device that the first network device is ready to apply a 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; 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.
