.
On the virtual I/O server, remove the mapping between HDLM devices
and virtual target devices. To inherit the hdisk configuration of the virtual
I/O client, inherit the mapping between virtual target devices and HDLM
devices.
¢
To inherit the mapping between virtual target devices and HDLM
devices:
$ rmdev -dev virtual-target-device-name -ucfg
