z/OS V1R9.0 UNIX System Services Command ... - Christian Grothoff

Note: These results only apply when the IGW022S message indicates an
Error Loc: EXTEND value. If it indicates an Error Loc: ARPN value, it
will go into the Out of Space error state and require an unmount
followed by a mount to reset the error condition and make the
reusable. The updates applied to the HFS since the last successful
SYNC will also be lost.
2. Unlike most z/OS UNIX commands, which reside in /bin, confighfs is found in
the /usr/lpp/dfsms/bin directory. You can symbolically link to the actual location
of confighfs. The symbolic link is found in /usr/sbin:
/usr/sbin/confighfs -> /usr/lpp/dfsms/bin/confighfs

Files
configstk {–s} Configuration_file_name
configstk is used to configure the AF_UEINT stack. This command should initially
be run from the /etc/rc script, which is executed as part of z/OS UNIX System
Services initialization. It should also be run each time the AF_UEINT network
topology changes after z/OS UNIX services have been initialized.
This command requires superuser authority.
–s Does syntax checking only.
configstk uses the following file:
Configuration_file_name
Specifies the configuration for the AF_UEINT stack. As with any
system-wide configuration file, it should have the appropriate permissions
set.
Syntax for Configuration Files
This file has two types of specifications, HOME and GATEWAY. Be careful when
modifying the configuration file to insure that the F_UEINT environment is not
corrupted due to user error.
HOME ip_address BUFFERS(number) blocking
This statement is required but you can only specify it once. The entire
statement must be on a single line.

ip_address
Defines the single virtual IP address to be used by all RS/6K clients
when accessing the z/OS host, independent of how many RS/6K
gateways are connected to a given z/OS image. This
implementation differs from the standard IP model which defines an
IP address per physical adapter.
number
Defines the maximum number of 32K page-fixed buffers (in OMVS
private memory) that are to be used by the protocol stack. The
