Adaptec SCSI RAID Software Reference Guide disk blink To cause a SCSI disk access light to blink (or stop blinking), use the disk blink command. Syntax disk blink [/wait{=boolean}] {scsi_device} {integer} Parameters {scsi_device} Specifies the ID for the SCSI disk you want to blink. A SCSI ID consists of a SCSI channel number (for example, 0, 1, 2, 3, etc.), SCSI device ID (0 through 15 inclusive), and SCSI device logical unit number (0 through 7 inclusive). See the scsi_device section on page 3-7 for more information on how to specify the SCSI device. {integer} Specifies the number of seconds you want the SCSI disk to blink. A value of zero (0) stops the SCSI disk from blinking. Switches /wait{=boolean} Specifies whether to perform verification synchronously or asynchronously. If you set this switch to TRUE, the command performs the block verification synchronously and the command prompt does not return until the block verification operation completes. The default is FALSE; the command performs the block verification asynchronously and the command prompt returns immediately. Examples The following example causes SCSI channel number 1, SCSI device ID 2, and SCSI device logical unit number 0 to blink for fifty-five seconds: AAC0>disk blink (1,2,0) 55 Executing: disk blink (CHANNEL=1,ID=2,LUN=0) 55 7-2
