4-3.24 Report Density Support command 44h
The REPORT DENSITY SUPPORT command provides a means for the initiator to retrieve informa-
tion maintained by the target about the supported densities for the MTU logical unit.
The support of the REPORT DENSITY SUPPORT command is con-
figuration dependent. In order for this command to be supported, FT4
(Feature Mode 4), bit 6 (0x40) must be set to 1. This bit can be set via
the CHANGE DEFINITION command (VPD page C1h, feature config-
uration byte 4) or via the operator panel, SETTING menu, option
80:S.FT4 (see Chapter 4 of the M2488 User's Guide). If the REPORT
DENSITY SUPPORT command is received when FT4, bit 6 is set to
0, CHECK CONDITION status is generated. The sense key is set to
ILLEGAL REQUEST with the additional sense code set to INVALID
CDB OP CODE.
