(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.
