Quantum Atlas 10K II Ultra160/m SCSI Hard Disk Drives
MODE SELECT (6) Command (15h) (continued)
5.14.1 Initiator-Changeable Mode Pages
Table 5-26 lists the mode pages that are supported by the drive. An initiator can
change these pages by supplying them, with the desired changes included, in the
MODE SELECT command’s data-out buffer transfer.
The initiator should first use a MODE SENSE command to read the appropriate
pages and leave non-changeable values as read when the initiator subsequently
writes the changeable pages with the MODE SELECT command. If a non-
changeable field contains an invalid value, the drive returns a CHECK
CONDITION status.
