disktest

7

The disktest verifies the functionality of hard disk drives and floppy drives using two subtests. Most disk drives, such as SCSI disks, native or SCSI floppy disks, IPI, and so on, are supported. The type of drive being tested is displayed on the top of the option menu. The media subtest verifies disk media by writing data to and reading data from the disk. The media subtest treats a disk as one large chunk of contiguous data. The File System subtest verifies the disk system's integrity.
Initially, disktest probes the disks under /dev/rdsk. It checks all of the partitions of each disk. If any partition has a file system not yet mounted, disktest pre-mounts these partitions for the File System subtest. The pre-mount point bears the name of the disk partition appended with a system-wide unique number. For example, if the disk name is /dev/dsk/c0t3d0, disktest mounts it as superuser under the name /c0t3d0.XXXXXX. Where XXXXXX is a six-digit system-wide number. The option menu shows all partitions available for testing. The File System subtest can only be run if the selected partition is mounted. The Write option of the Media subtest is allowed only if selected partition is not mounted.
The disktest tests the floppy drive regardless of whether or not the Volume Management software is running.
  • If the Volume Management software is running, disktest tests the disk drive with the mount point name in the /etc/mnttab file.
CAUTION Caution - If a power failure occurs while the Media subtest is being run in write mode, disk data will be destroyed.
  • If the Volume Management software is not running, disktest tests the disk drive with the device name dev=/dev/diskette. Do not edit the /etc/vold.conf file to change the floppy drives. Currently, the sunvts software is hard-coded to use these path names as the default logic name.
The disktest performs a random seek check followed by a read test or a read after write test. The Media subtest is a scalable test; so you can run multiple copies of it in read/write mode on the same disk partition. To avoid data corruption, all simultaneous instances of disktest communicate through a shared memory service. This ensures that different copies of the Media subtest do not overlay the same disk block at the same time.
The File System subtest exercises the partition being tested determine if it is mounted. If the partition is not already mounted or pre-mounted, then the test is blocked.

The disktest has different option menus for different test modes.
Partition: The partitions for the Media subtest are displayed. If a partition is mounted, it's mount point is appended after the partition number, such as 1(/usr). Where 1 is the partition number, and /usr is the mount point.
Test Media: Enable or Disable of Media subtest.

disktest Test Modes

The disktest supports all three modes. It performs different test schemes on the network device, according to the mode you select.
Connectivity Mode This mode is only available for the hard disk test. There is no Connectivity Mode for floppy driver test. Only one instance of disktest is allowed for each disk device. A disktest monitors UNIX error messages. The disktest displays messages and reports errors. The test also opens the hard disk, checks the disk configuration, reads a few blocks, and then closes the hard disk. No File System subtest will be run. No Write option is available in Connectivity Mode.
Online Mode The Online Mode is only available for the hard disk test. There is no Online Mode for the floppy driver test. Only one instance of disktest is allowed for each disk device. A disktest monitors UNIX error messages. disktest displays messages and reports errors.
In this mode, disktest also opens the hard disk, checks the disk configuration, and executes the Media subtest. Next, disktest performs some random seek checks. Only Read Only mode is allowed. The default coverage is 10%. No File System subtest will be run. When the test finishes, disktest closes the disk device being tested. No Write option is available in Online Mode.
Offline Mode More than one instance of disktest is allowed for one disk device. Both File system subtest and Media subtest can be run in Offline mode. The disktest does not monitor UNIX error messages in this mode. Floppy test can be run in Off-line mode.
