(2) Removing Devices from VxVM on a Controller Basis

If physical paths connected to one LU go through different HBAs, devices are removed

from VxVM on a controller or path basis. The procedure for removing devices from

VxVM on a controller basis is described below by using the configuration example

shown in Figure 3-23: When HBA ports on the alternate path differ from those on the

primary path connected to the Hitachi storage system. This figure shows a

configuration that is recognized by VxVM before devices are removed.
