Multisystem Configuration
•
Regardless of the CPU configuration for the Parallel Library TCP/IP (TCPSAM)
process, the QIO sockets interface is used by the IOP to access the Parallel
Library TCP/IP process.
Multisystem Configuration
A SWAN configuration can be accessed alternately by more than one system. The
WAN configuration allows you to issue an SCF command to instruct another system to
take control of the SWAN configuration. This method assumes that system was not
already controlling the SWAN configuration. Multisystem configuration is executed as
follows:
•
The WANBoot process does not reply to BOOTP requests when the server is in
the STOPPED state. Also, the WANBoot process does not issue BOOTP requests
to the SWAN concentrator if an ADD or ALTER command is issued on the adapter
or path.
•
The WANBoot process issues a request to the WAN manager process to ABORT
SERVER when a BOOTP request is received from another system for a path on a
server supported by the WANBoot process.
•
A START SERVER command causes a system to take control of the SWAN
configuration. The START SERVER command issues a BOOTP request to the
CLIP, therefore taking control of the CLIP.
•
A SWAN firmware update can be initiated as follows:
°
For the OSM Service Connection, use either the Multi-Resource Actions dialog
box (for updating multiple SWAN CLIPs) or the Actions dialog box (for
individual SWAN CLIPs).
°
For the TSM Service Application (G-series RVUs only), use the SWAN Fast
Firmware Update guided procedure or the Firmware Update dialog box.
Note. The SWAN Fast Firmware Update guided procedure is supported only on G06.13
and subsequent software RVUs.
For more information about updating SWAN firmware, see the SWAN Concentrator Instal-
lation and Support Guide or the SWAN 2 Concentrator Installation and Support Guide,
depending on the type of concentrator.
