B.1 ALPHAbook 1 (Alpha Only)
V7.1
The following sections contain release notes specific to the ALPHAbook 1
notebook computer.
B.1.1 Using the SCSI_MODE Utility
The OpenVMS Alpha operating system includes a generic SCSI_MODE utility
that allows privileged users to modify a SCSI device’s mode pages. By using this
utility to enable automatic disk spindown, users can save approximately 2 watts
of power. Because mode pages are saved on the disk drive, the state is saved
across power cycles.
The following example shows how to enable automatic SCSI disk spindown after a
1-minute timeout period. (To select a spindown time other than 1 minute, replace
the ‘‘01’’ following the " - offset f" with the desired number of minutes expressed
as a 2-digit hexadecimal value.) Use this procedure only on the internal drive of
the ALPHAbook 1 notebook computer. Note that the parameter values shown in
this example apply only to DVAS-2810 devices. To identify the SCSI disk devices
on your system, use the SHOW DEVICE/FULL DK command.
