During the FC-SCM discussions at T11, we noticed that Annex D contains
some incorrect discovery steps (specifically in the area of step 6 and
step 7).
6)For each Port Identifier returned in the accept CT_IU for the GID_FF,
perform login and Process Login, and issue an INQUIRY command to LUN 0
to identify the type of target (see 6.2 and SPC-4);
7)If the INQUIRY succeeds, issue a REPORT LUNS command to LUN 0 to
obtain a list of the logical units accessible through the target
FCP_Port (see SPC-4);
This assumes things that SPC does not require.
6) the INQUIRY command should be sent to either LUN 0 or to the REPORT
LUNS well known logical unit (and this will NOT identify the "type of
target"; step 8 is what tells you the type of each LUN).
7) the REPORT LUNS command should be sent to either LUN 0 or to the
REPORT LUNS well known logical unit.
