NOTE Table 2-101 Library SCSI-3 Command Set Log Select Command (4CH) Parameter List Length The parameter list length field specifies the length in bytes of the parameter list that shall be located in the Data-Out Buffer. A parameter list length of 0 indicates that no pages shall be transferred. The parameter list length shall not result in the truncation of any log parameter. The application client should send pages one page code at a time. Initiators should issue LOG SENSE commands prior to issuing LOG SELECT commands to determine supported pages. The target does not support independent sets of log parameters and if any log parameters are changed that affect other initiators, then a unit attention condition for all initiators will be generated. This unit attention condition shall be returned with an additional sense code of LOG PARAMETERS CHANGED. Log Select Data Format The Log Select shall have the following format or the format of the Log Sense in Table 2-102 on page 2-123. Log Select Page Data Format Byte Description 0 Page Code 1 Reserved 2 Number of bytes to follow (MSByte) (0) 3 Number of bytes to follow (LSByte) (0) 2- 122 Chapter 2
