Command Line User Interface 153
Command Line User Interface
Command Aborts Received (1.05
release)
Abort Sequences Received (prior
to 1.05)
OPAQUE
(7100/
7400/7110)
FRONTEND-
PORT (7410)
The number of SCSI abort requests received.
Usage
This metric can be compared with the “Command Frames
Received” and “Queue Full Statuses Sent” metrics to see if
there is a significant issue in the current operation of the
array. If Queue Full or Abort is more than a very minor
portion of the commands being received, then there is a
problem that needs to be addressed.
Command Frames Received OPAQUE
(7100/
7400/7110)
FRONTEND-
PORT (7410)
The number of SCSI commands received.
Usage
This includes all commands not just the read and write
commands. This metric can be compared with the “Queue
Full Statuses Sent” and “Abort Sequences Received”
metrics to see if there is a significant issue in the current
operation of the array. If Queue Full or Abort is more than
a very minor portion of the commands being received,
then there is a problem that needs to be addressed.
Commands Timed Out BACKEND-
PORT
The number of commands to targets on the back end loop
that were aborted before they completed due to excessive
execution time.
Usage
A high number of back end aborts may effect
performance and may be an indication that hardware
repair is needed.
Compatibility
BACKEND-PORT metrics are available for VA 7410 only.
