Using the -f option

Use the -f option to test disks that are listed in a text file. For example, you can create a file to test two disks shared by systems north and south that might resemble:

north /dev/sdz south /dev/sdy

north /dev/sdu south /dev/sdw

Where the first disk is listed in the first line and is seen by north as /dev/sdz and by south as /dev/sdy. The other disk, in the second line, is seen as /dev/sdu from north and /dev/sdw from south. Typically, the list of disks could be extensive.

Suppose you created the file named disks_blue. To test the disks, you would enter:

# /opt/VRTSvcs/vxfen/bin/vxfentsthdw -f disks_blue

The utility reports the test results one disk at a time, just as for the -m option.

You can redirect the test results to a text file. Precede the command with "yes" to acknowledge that the testing destroys any data on the disks to be tested.

  Caution   Be advised that by redirecting the command's output to a file, a warning that the testing destroys data on the disks cannot be seen until the testing is done.

For example:

# yes | /opt/VRTSvcs/vxfen/bin/vxfentsthdw -f disks_blue > blue_test.txt
