Adaptec RAID 2810SA Software Reference Manual page 213

/wait{=boolean}
Specifies whether to clear the disk synchronously or
asynchronously. If you set this switch to TRUE, the command
clears the disk synchronously and the command prompt does
not return until the clear disk task completes.
The default is FALSE; the command clears the disk
asynchronously and the command prompt returns
immediately.
Examples
The following example clears SCSI disk (0,2,0). There is data on the
disk. However, the data is not deemed important and thus the
/always switch is used:
AAC0> disk zero /always /wait (0,2,0)
Executing: disk zero /always=TRUE /wait=TRUE (CHANNEL=0,ID=2,LUN=0)
As the command executes, note the title bar of the DOS window
displays the status of the command. For example:
Stat:OK!Task:100,Func:SCZ,State:RUN 97.2%
See page 3-10 for detailed information on the status information that
the command displays in the title bar as it executes the task.
