Library SCSI-3 Command Set Mode Select (10) Command (55H) If a host sends a MODE SELECT (10) 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 (10) command. The host server will also set the additional sense condition to MODE PARAMETERS CHANGED. Page Format (PF) Zero indicates that all parameters after the block descriptors are vendor-specific. One indicates that the MODE SELECT (10) parameters that follow the header and block descriptor(s) are structured as pages of related parameters. Save Pages (SP) Zero indicates the device server shall perform the specified MODE SELECT (10) operation and not save any pages. One indicates that the device server shall perform the specified MODE SELECT (10) operation and save as non-volatile. Table 2-119 Byte 7 0-5 6 7 Parameter List Length The parameter list length field specifies the length in bytes of the mode parameter list. The device server will terminate the command with CHECK CONDITION status if the parameter list length truncates the mode parameter header, mode parameter block descriptors, or mode page. Mode Sense (10) Parameter Header 6 5 4 3 2 1 0 Reserved (0) Block Descriptor Length (MSByte) (0) Block Descriptor Length (LSByte) (0) Block Descriptor Length This byte is not valid for libraries.
