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. 

This is a scalable test that can run multiple copies 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.

File System Subtest 

Verifies the disk system's integrity. The file system subtest exercises the partition being tested to determine if it is mounted. If the partition is not already mounted or pre-mounted, then the test is blocked. The test opens two temporary files (of the size specified on File System File Size) and performs a Read/Write test.

Asynchronous I/O Subtest 

Uses the asynchronous read/write feature of the Solaris disk driver to exercise the disk. In read-only mode, the test sends a maximum of four asynchronous read packets, each with a random size and a random offset into the selected partition. The test then waits for all outstanding I/O activity to complete before issuing another round of packets. This process continues until the whole area is tested. In read-write mode, one write packet is issued in every four read packets as a spot check of the write operation. Before data is written to a particular location, data is backed up, write-verified, and restored to its original state. 

Partition 

Displays the partition for the Media subtest. If a partition is mounted, its 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 

Enables or disables the Media subtest. 

Media Write Read Mode 

Enables Read-Only or Read mode after write, with or without backup. 

Media Coverage (%) 

Enables users to test all or part of a partition (in percentages). 

Test File System 

Enables or disables the File System subtest; File System File Size: creates a file system file size twice the size as what is specified. 

File System Transfer Size 

Displays the transfer size of the File System subtest. File System Test Pattern: Test pattern of File System subtest.

NOTE: The floppy disktest can only be run in Functional test mode.

Connection Test 

This mode is only available for the hard disk test. There is no Connection test for the floppy driver test. Only one instance of disktest (which monitors UNIX error messages) is allowed for each disk device. 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 is run. No Write option is available in Connection test.

Functional Test 

This mode does not allow disktest to monitor UNIX error messages. More than one instance of disktest is allowed for one disk device. Both the File System and Media subtests can be run in Functional test.The floppy test can also be run in Functional test mode.

If you invoke SunVTS through SyMON, the following Functional Test description applies:  

This 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, which 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 random seek checks. By default the media sub-test performs a read-only test on 30% of the partition under test. No File System subtest is run. When the test finishes, disktest closes the disk device being tested. No Write option is available in Online mode.
