LOCLAN and ZASLAN connections exist in the HNC. From the BS2000 viewpoint these
connections are presented as emulated BS2000 devices. A service engineer creates the
BS2000 connections when the HNC is placed in service.
A BS2000 connection consists of a device pair, i.e. of a write and a read device. A
connection therefore always has two unit IDs on the HNC and, possibly, two BS2000
mnemonics in BS2000.
Assignment of the BS2000 MNs when configuration takes place is optional and is only done
for documentation purposes. Consequently it is not an error and it has no repercussions on
ongoing operation if no BS2000 MNs are assigned. They can also be configured subse-
quently (by Customer Support) during ongoing operation.
WWPN and virtual WWPN
An unambiguous WWPN (World Wide Port Name) which identifies the connection is
assigned to each Fibre Channel connection. If you have the hardware for a Fibre Channel
connection exchanged and if the old FC controller will certainly no longer be used, you can
continue to use the old WWPN as a virtual WWPN. Discuss the specific procedure with
Customer Support when you replace the hardware.
Configuring connections in BS2000
The device pair of a ZASLAN or LOCLAN connection must be generated in the BS2000
system. This can be done statically via the IOCF file (see the "System Installation" manual
[1]) or during ongoing operation for the current BS2000 session using
the "Commands" manual [5]). BS2000 MNs are defined for the unit IDs which implement
the ZASLAN or LOCLAN device. In the example below the MNs are referred to as
and
<mn2>
In VM2000 mode the communication devices must be assigned exclusively to the guest
system concerned (possibly by and entry in the RUN file for starting the VM), see the
"VM2000" manual [3]:
/ADD-VM-DEVICES UNITS=(<mn1>,<mn2>), VM-ID=<vm-id>
