Problem-isolation and debug functions
The IPSSEND problem-isolation and debug functions include the following:
eraseevent Use the eraseevent function to clear all logged entries in the
designated event log. See getevent help for information about the
contents of the device event log and the controller soft and hard
event logs.
Supported operating systems: Windows NT, Windows 2000
Command: ipssend eraseevent controller options
where:
v
controller is the ServeRAID controller number (1–12)
v
options is the designated event log:
– DEVICE for the device event log
– SOFT for the ServeRAID controller soft event log
– HARD for the ServeRAID controller hard event log
getbst Use the getbst function to display the number of bad stripes in the
bad stripe table for each logical drive.
Supported operating systems: Windows NT, Windows 2000
Command: ipssend getbst controller
where:
controller is the ServeRAID controller number (1–12)
getevent Use the getevent function to display information about various
unexpected events. IBM service representatives use the soft and
hard event logs for development and debugging purposes only. The
device event log contains event counters for each attached physical
device. These counters include:
v
Parity: An unexpected event occurred while data was being
transferred on the SCSI bus. This usually indicates a problem
with the SCSI cable, connectors, or terminators.
v
Soft: A SCSI device detected a check-condition event.
v
Hard: The SCSI controller detected an unexpected event. The
controller is the most likely cause.
v
Misc: The ServeRAID controller detected an event that was most
likely caused by the device.
The device event log also provides PFA alerts, which indicate that
the device has signaled the ServeRAID controller that it might fail in
the near future.
Supported operating systems: Windows NT, Windows 2000
Command: ipssend getevent controller options
where:
v
controller is the ServeRAID controller number (1–12)
v
options is the designated event log:
– DEVICE for the device event log
