ALTER ADAPTER Command
The WAN manager process uses the persistence principle to resolve the file in the
current SYSnn/CSSnn to locate the files. This keeps the most recent files being
used even when the SYSnn/CSSnn changes.
The WAN manager process resolves the subvolume using this algorithm:
1. First, the WAN manager process checks for the file in the current
SYSnn/CSSnn.
2. If the file does not exist in the current SYSnn/CSSnn, then the WAN manager
process checks for the file in the SYSTEM subvolume.
3. If the file does not exist in the SYSTEM subvolume, then the WAN manager
process checks for the file in the specified subvolume.
4. If the file does not exist in any of these subvolumes, an error is generated and
the WAN manager process does not exit.
5. If the file was located in one of the subvolumes, the WAN manager process
configures the object with the file resolved and saves the resolved subvolume
in the system CONFIG database.
6. The WAN manager process applies this algorithm, while accepting SCF ADD
and ALTER commands and during the coldload of the system (and restart of
WANMGR). This action ensures that the files are taken from the current
SYSnn/CSSnn or SYSTEM subvolumes.
•
The file name specified in the KERNELCODE attribute is
$SYSTEM.CSSnn.xxxxxPxx when specifying the SWAN microcode file name and
$SYSTEM.CSSnn.xxxxxQxx when specifying the SWAN 2 microcode file name.
•
The file name specified in the KERNELCODE attribute must be secured with N
read access.
•
If the KERNELCODE attribute specified does not match the ADAPTER TYPE
configured, the command fails and an error is generated.
•
The value for TRACKID is case-sensitive. If you specify the value incorrectly, you
cannot use the SWAN concentrator. In this case, the WAN subsystem and the
OSM discovery processes and TSM (G-series RVUs only) discovery processes will
not find the SWAN concentrator when it is powered on.
•
If the ALTER ADAPTER command changes the subnet (HOSTIP and TCP/IP),
WanMgr automatically configures WANBoot, TFTP, and SNMP trap multiplexer
processes if the subnet configured has no WANBoot, TFTP server, or SNMP trap
multiplexer processes. The combinations of the HOSTIP and TCP/IP attribute
generate an error if the altered HOSTIP is already configured with a different
TCP/IP (in other ADAPTER configurations) than the one being altered.
•
The ALTER ADAPTER command does not allow you to change the TYPE of
adapter from SWAN 2 to SYNC or FWTCL and vice versa.
Note. This algorithm applies only if the volume is a system disk (usually $SYSTEM).
