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.

** NOTE **

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.
