The MODE SELECT (6) command (15H) allows the host to specify device parameters to the target. Hosts should issue MODE SENSE (6) (1AH) prior to each MODE SELECT (6) to determine supported pages, page lengths, and other parameters. NOTE See "Mode Sense (6) Command (1AH)" on page 2-29 for a description of the mode page codes. PS = 0 for Mode Select. Table 2-17 Mode Select (6) Command CDB Byte 0 1 7 6 5 4 3 2 1 Operation Code (15H) Reserved (0) PF (0) Reserved (0) 2 Reserved (0) 3 Reserved (0) 4 Parameter List Length 5 Control Byte (0) 0 SP (1) If an application sends a MODE SELECT (6) command that changes any parameters applying to other initiators, the device server will generate a unit attention condition for all initiators, except the one that issued the MODE SELECT (6) command. The device server will also set the additional sense condition to MODE PARAMETERS CHANGED. NOTE Changing fibre channel configurations may result in a different device address after the host computer is rebooted. It is recommended to change fibre configurations through the library front panel or remote management card. Chapter 2 2- 23
