Remote Access Concentrator DumpsThe Remote Access Concentrator dumps itsm emory image toa host
running load server softwarew hencertain software or hardware events
occur.
Dumpfiles are generated for use by technical support personnel
only.
Events that trigger Remote Access Concentrator dumps are:
• Non-recoverable hardware or software errors.
• Softwarefails to reset the Remote Access Concentrator’s
watchdogtimer.
• Softwarefails one or more internal consistency checks.
• Hardware detects an internal fault.
The Remote Access Concentrator sends a dump fileto a preferred load
dump host. If you do not define this host by specifying an address, the
RemoteAccess Concentrator broadcasts a request and dumps to the first
host that responds.
TheRemote Ac cessConcentrator sends a dump to the /usr/spool/erpcd/
bfsdirectory on the dump host. The /usr/spo ol/erpcd/bfs directory is a
default pathname and can be changed.The receiving Remote Access
Concentrator assignsa unique file name for each device that it receives
a dump from but not for each crash dump.
Rename any crash dumps that you want to save.Erpcd
overwritescrash dumps if the same unit dumps again.
The assigned name depends on the number ofc haractersper file name
thatthe dump host supports. For hosts supporting file names longer than
14 characters (e.g.,most modern UNIX hosts), dump files are named
dump.addr.The file extension addr is the Remote Access
Concentrator’s IP address.
