21       -h hfi    Specifies the HFI, numbered 1..n. Using 0 specifies that  the
22                 -p port port is a system-wide port number. (Default is 0.)
23

25       -p port   Specifies  the  port,  numbered  1..n.  Using 0 specifies the
26                 first active port. (Default is 0.)

34                 Information about the links disabled  is  written  to  a  CSV
35                 file.   By   default,   this   file  is  named  /etc/opa/dis‐
36                 abled:hfi:port.csv where the hfi:port part of the  file  name
37                 is replaced by the HFI number and the port number being oper‐
38                 ated on (such as 1:1 or 2:1). This CSV file can  be  used  as
39                 input to opaenableports.

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