Detailed Recovery Of A Board In Case Of Fault - Sun Microsystems Netra CT 820 Administration Manual

Printing PMS Recovery Configuration Information
The pmsd infoshow -s slot_num|all command can be used to print the recovery
configuration and alarm status for the recovery configuration.
The pmsd historyshow -s slot_num|all command can be used to print a recovery
configuration and runtime message log. The log is printed to the ChorusOS terminal
performing the operation.

Detailed Recovery of a Board in Case of Fault

You can perform detailed, manual recovery operations on a board or instruct PMS to
perform detailed, automatic recovery operations on a board using the CLI. The
operations are performed across the hardware, the operating system, and the
applications.
For manual recovery, use the pmsd recoveryoperset -s slot_num|all command.
This command can only be run when the board is in maintenance mode or none mode
(PMS applications are offline). You specify the recovery operation to be performed
on the specified slot by using the option -o with the parameters: pc (power cycle),
rst (reset), rstpc (reset, then power cycle), pd (power down), or rb (reboot).
For automatic recovery, use the recoveryautooperset -s slot_num|all
command. This command instructs PMS what to do in response to a fault when the
board is in operational mode (PMS applications are active).
You specify the automatic recovery operation to be performed on the specified slot
by using the option -o with the parameters: pc (power cycle), rst (reset), rstpc
(reset, then power cycle), pd (power down), or rb (reboot), rbpc (reboot, then
power cycle), none (no recovery), or trg (manually simulate a fault to trigger a
recovery). Optional parameters for automatic recovery include: -d startup delay
(the time in deciseconds between a fault occurrence and the start of a recovery
operation; default is 0 deciseconds), -f off|on (whether a power down operation
will occur if the recovery operation fails; on specifies power down will occur and
off specifies that power down will not occur; the default is off), -r retries (the
number of times a recovery operation can occur and fail before it is terminated; the
default is one try), -n inter_op_delay (the time in deciseconds between one and the
next operation for an operation with multiple retries; the default is 0 deciseconds [1
decisecond equals 10 milliseconds]; you should change the default to a number other
than 0, for example, 4000 [equals 40 seconds], to allow time between the operations),
and -p reset_power-cycle_delay (the time in deciseconds to be waited between the
reset and power cycle portions of the recovery operation before a failed reset is
declared and the power cycle portion of the operation starts; default is 0
deciseconds).
