NAME

       opadisablehosts

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

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.
