       (Linux)  Searches for a set of hosts in the fabric and disables their corresponding switch

Syntax

       opadisablehosts [-h  hfi] [-p  port]  reason  host ...

Options

       --help

                 Produces full help text.

       -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 the text describing the reason hosts are  being  disabled.  reason  is
                 saved in the reason field of the output file.

                 Information  about the links disabled is written to a CSV file. By default, this
                 file is 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.

                 The  list   is   of   the   form:   NodeGUID;PortNum;NodeType;NodeDesc;NodeGUID;
                 PortNum;NodeType;NodeDesc;Reason For each listed link, the switch port closer to
                 this is the one that has been disabled.

       host ...

                 Defines one or more hosts that are affected by the reason.

-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.
