Testing the shared disks listed in a file using the vxfentsthdw -f option
Use the -f option to test disks that are listed in a text file. Review the following example procedure.
To test the shared disks listed in a file
- Create a text file
disks_test
to test two disks shared by systemssys1
andsys2
that might resemble:sys1 /dev/sdz sys2 /dev/sdy sys1 /dev/sdu sys2 /dev/sdw
where the first disk is listed in the first line and is seen by
sys1
as/dev/sdz
and bysys2
as/dev/sdy
. The other disk, in the second line, is seen as/dev/sdu
fromsys1
and/dev/sdw
fromsys2
. Typically, the list of disks could be extensive. - To test the disks, enter the following command:
# vxfentsthdw -f disks_test
The utility reports the test results one disk at a time, just as for the -m option.
