NAME

       opadisableports

       (Linux) Accepts a CSV file listing links to disable. For each HFI-SW link, the switch side
       of the link is disabled. For each SW-SW link, the switch  port  closer  to  this  node  is
       disabled.  This  approach generally permits a future opaenableports operation to re-enable
       the port once the issue is corrected or ready to be retested. The list of  disabled  ports
       is tracked in /etc/opa/disabled*.csv.

Syntax

       opadisableports [-R] [-h  hfi] [-p  port] [ reason] < disable.csv

Options

       --help

                 Produces full help text.

       -R

                 Does not attempt to get routes for computation of distance. Instead, it disables
                 the port of the switch with the lower LID (which is often the  side  closest  to
                 the SM) assuming that it is closer to this node.

       -h hfi

                 Specifies  the  HFI, numbered 1..n. Using 0 specifies that the -p port port is a
                 system-wide port number. Default is 0.

       -p port

                 Specifies the port, numbered 1..n. Using 0  specifies  the  first  active  port.
                 Default is 0.

       reason

                 Specifies  optional  text describing why ports are being disabled. If used, text
                 is saved in the reason field of the output file.

       disable.csv

                 Specifies the input file listing the links to disable. The list is of the  form:
                 NodeGUID;PortNum;NodeType;NodeDesc;NodeGUID;PortNum; NodeType;NodeDesc;Reason

                 The  reason  field  is  optional. An input file such as this can be generated by
                 using opaextractbadlinks, opaextractmissinglinks, or opaextractsellinks.

       Information about the links disabled and the reason is saved (in the same  format)  to  an
       output  file named /etc/opa/disabled:hfi:port.csv where the hfi:port part of the file name
       is replaced by the HFI number and the port number being operated on (such as 1:1 or  2:1).
       This CSV file can be used as input to opaenableports.

-h and -p options permit a variety of selections:

       -h 0

                 First active port in system (Default).

       -h 0 -p 0

                 First active port in system.

       -h x

                 First active port on HFI x.

       -h x -p 0

                 First active port on HFI x.

       -h 0 -p y

                 Port y within system (no matter which ports are active).

       -h x -p y

                 HFI x, port y.
