Troubleshooting EMS HA over ATM
Chapter 9 267
NOTE EMS High Availability over ATM (EMS HA-ATM) is managed by the
EMS HA-ATM functionality incorporated into the core ATM software
running on the HP ATM adapter. EMS HA-ATM handles local recovery
within a system. MC/ServiceGuard handles remote recovery from one
system to another, when EMS HA-ATM notifies EMS that local recovery
is no longer possible. This section covers only troubleshooting of local
recovery managed by EMS HA-ATM. For details about troubleshooting
remote recovery, see your MC/ServiceGuard documentation and “D” later
in this section.
A Examine the EMS HA-ATM log files. A log file for each primary
ELAN interface is in this file:
/var/opt/hatmmon/log/ ELAN_interface _hatmmon.log
To check all the log files on a system, type this command:
more /var/opt/hatmmon/log/*hatmmon.log*
Table 9-3 below shows the events that can be displayed in the log file:
