For logical device files of HDLM devices, the number of such files to be

created is the same as the number of slices for one LU.

The following figure shows the devices that are recognized by VxVM after the

non-HDLM devices are disabled.

Figure 3-24 Devices Recognized by VxVM after Removal of Devices from

VxVM

Only HDLM devices (c5t0d0) that are actually created are recognized. In this

case, HDLM functions, such as load balancing and failover, work normally.

Note

After VxVM is installed, if the vxdiskadm utility has not been used to

suppress a device or DMP from VxVM, the settings files such as /etc/vx/
vxvm.exclude may be absent. If these settings files do not exist, you

may be unable to suppress devices correctly.
The settings files necessary for device suppression are created by

selecting menu task 17 (Prevent multipathing/Suppress devices
from VxVM's view) or 18 (Allow multipathing/Unsuppress devices
from VxVM's view) from the vxdiskadm main menu, and then by

selecting menu task 8 (List currently suppressed/non-multipathed
devices) from the VolumeManager/Disk/ExcludeDevices or
VolumeManager/Disk/IncludeDevices menu.

Removing Devices from VxVM on a Controller Basis

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

removing devices from VxVM on a controller basis is described below by using
