1  SET_Command
   Sets WWID characteristics

   SET WWID /PRODUCT_ID=<product-id-substring>
            /PORT=<wwid> 
            /CAP=<cap>
            /[NO]WAIT
            /DEFAULTS

2  /PORT=<wwid>
   Select WWIDs to modify by fully matching the specified Port WWID.
   /PORT may not be used with /NODE

2  /PRODUCT_ID=<product-id-substring>
   Select WWIDs to modify by fully matching (including case) the
   specified substring to any portion of the WWID's product ID

2  /CAP=<cap>
   Specifies the maximum number of I/Os which will be allowed to be
   active at any time across all paths to all LUNs on the selected 
   WWIDs. SANCP and the port drivers will enforce minimum and maximum
   values, are currently 8 and 65,535 (decimal) respectively

   Changing a WWID's I/O cap to other than the stock value can greatly
   impact I/O performance, so, to ensure that only intended WWIDs are
   modified, unless /DEFAULTS is used /CAP is only supported with some
   combination of /PORT, /NODE and /PRODUCT_ID 

2  /[NO]WAIT
   /WAIT and /NOWAIT are only supported with /CAP

   /WAIT - the I/O cap value set with /CAP will not take effect until
   at least one Queue Full has been seen on the selected WWIDs; if the
   Queue Full count is non-0 when this qualifier is processed, the cap
   will take effect immediately

   /NOWAIT - the I/O cap value set with /CAP will take effect 
   immediately

2  /DEFAULTS
   Restore default values for all fields of the selected WWIDs.
   /DEFAULTS cannot be used with /CAP
