This strategy reduces the use of limited resources like port connections. The patch provides a common infrastructure which could be used for all WKA ports in future. Also reduce the number of nameserver lookups by changing the zfcp behaviour of always querying the nameserver for the corresponding destination ID of the remote port. If the destination ID has changed during the reopen process we will be informed and then trigger a nameserver query on demand.
