Examples--Checking Disk Activity
These two examples illustrate the sar -d output. The first example is from a computer with a non-SCSI (Small Computer System Interface, pronounced "scuzzy") integral disk; that is, a disk that does not use a SCSI interface. This example illustrates data being transferred from a hard disk (hdsk-0) to the floppy disk (fdsk-0).

The following example is from a computer with SCSI integral disks; that is, disks that use a SCSI interface. The example illustrates data being transferred from one SCSI hard disk (sd00-0) to another SCSI integral disk (sd00-1).
