Troubleshooting
User Options
There are three hidden eqcli options to control the behavior:
1.
debug >configd ipmi_nmi <seconds>
This sets the IPMI NMI timer. It has no effect on systems that do not have an IPMI (
ipmi0
)
watchdog timer. The default value is 0.
2.
debug > configd require_hw_wd <0 or 1>
Defers loading the network subsystem until after a hardware watchdog has been armed.
Has no effect if the watchdog has been completely disabled (reset timer is 0). Does not do
anything until after the system is rebooted. The user will see "
Waiting for system pro-
cesses... " along with this message in the eq log:
20140127T190024| configd|w|04007413
:
Deferring the system startup until the hardware watchdog timer becomes available applies
to both the PCI (
ichlpcib0
)and IPMI (
ipmi0
) watchdogs timers, although the PCI watchdog
should always be loaded on the first try if it is available and usable in the system. The
default value is 0.
3.
debug > configd debugger_on_panic <0 or 1
>
Sets the
ddb.onpanic sysctl
. The default is 0. If set to 1, the system enters the debugger
on panic or on NMI. Therefore, if set and the IPMI watchdog NMI timer is active, the system
will enter the debugger when the watchdog expires instead of a panic.
Note - The "reset" timer is controlled by the already-existing "hidden watchdog <seconds>" command.
When the system boots, a message (or two messages) will be output to the O/S log:
Jan 27 19:00:08 FADC600E-PROTO root: Starting watchdog timer swwdog0 with interval 30.
...
Jan 27 19:00:47 FADC600E-PROTO root: Starting watchdog timer ipmi0 with interval 30.
All of these options are stored in the configuration file and are synched between failover peers.
An typical example is as follows:
The default behavior is:
NMI timer = 0
debugger_on_panic = 0
require_hw_wd = 0
reset timer = 30 This means that if Equalizer "locks up", the IPMI watchdog will CPU-reset after
30 seconds. No debugging information will be available.
A customer that experiences such a problem may set up their system as follows:
NMI timer = 30
debugger_on_panic = 1
reset_timer = 29
