Using the ARM Command Line Utilities for Windows NT Performing Disk Array Maintenance Tasks Testing a Disk Diagnostics allow you test the operation and integrity of a disk. Three different types of testing can be performed: • Write/read/verify - a destructive test that will destroy data on the disk being tested. The disk must be downed before beginning the test. • Read/verify - a nondestructive test that will not alter any data on the disk being tested. It is not necessary to down the disk before performing a read/ verify test. • Self-test - a nondestructive internal test that checks the operation of the disk. To perform a write/read/verify test of a disk, type: drivetest -D slot -w percent To perform a read/verify test of a disk, type: drivetest -D slot -r percent To perform a self-test of a disk, type: drivetest -D slot -s percent is the percent (0 to 100) of the disk to be tested slot is the cabinet shelf containing the disk drive (A1 through A6, or B1 through B6) Displaying Test Results After the disk testing is complete, the test results can be displayed for analysis by using the dteststat utility.
