HP Surestore Bridge FC 2/1 LV and FC 4/1 HV Installation and Operations Guide

Appendix B In-Band Management 215
In the situation where the SCSI host is unable or unwilling to talk to any LUN
except for the known controller LUN, the host can perform a REPORT LUNS
command (See Table 14 ). The bridge will respond with a list of all
addressable LUNs. Each of these LUNs reported can then be queried for
inquiry data. The first two bytes of each SCC LUN are inserted into the FCP
Logical Unit Number field on the Virtual Inquiry Command. The bridge will
forward the inquiry to the device and return that device's Inquiry Data back.
EVPD - CmdDt: The combination of EVPD and CmdDt determine the use of the
Page Code or Operation code field, and the type of Inquiry data returned:
(CmDt | EVPD):
00: return standard Inquiry Data (as shown below)
01: return Vital Product Data (VPD) for the specified Page Code
10: return Command Support Data for the specified Operation Code
11: invalid bit combination
