How to check that a device is attached on a port

Q1: can anyone tell me how cfgadm keeps track of the device even if the device is disconnected ,

when we disconnect a device using cfgadm
cfgadm -ys disconnect <ap_id>

then the device disappears from the lshal o/p. HAL uses libdevinfo for the device list. if the device is not there in the /dev i think the system resources assigned to that device are freed. it means we can't keep track of that device. cfgadm does so. we can reconnect it from there... how it is done ?
