INFORMATION RELEASE AB 167
REMOVE EXISTING AB167 COMPLETELY AND REPLACE WITH THIS AB 167/1
DISABLING RIO CONSOLE MESSAGES
RIO host adapters continually poll RTA's to ensure that a Communications Path exists.
In the event that a RTA fails to respond then a rio disconnect message is displayed on the system console. Once a RTA responds then a rio reconnect message will be displayed on the system console.
Remote RTA's, connected via LDMs and kilostream links, generate large numbers of these connect/disconnect messages. This is apparently due to timing issues associated with the clocks which are delivered from the kilostream link.
NO DATA LOSS IS APPARENT
The quantity of these messages have been causing concern at some users sites. Therefore, effective from the date of this release, all rio messages and the system console are to be disabled.
To disable rio console messages:-
#/etc/config.rio -l 2
To disable rio console messages as a part of system boots:-
vi/etc/rc2.d/S99RIO
- add the line:-config.rio -l 2
Rio messages are still written to /etc/.osm
This can be displayed by:-
#pg /etc/.osm
Console messages can be enabled for diagnostic/ configuration purpose by entering:-
#/etc/config.rio -l 1
