This error is received because of bug 14852156. The error is corrected in version 220.127.116.11.4. You can apply a patch for the error or you can generate a solution by following the procedure below.
Make a backup of $GI_HOME/lib/osds_acfslib.pm.
The required change in the osds_acfslib.pm file is:
Find the following line in this file.
my ($vers) = "unknown";
my ($kver) = $UNAME_R;
my ($supported) = 0;
my ($test_mode, $test_release, $test_version, $test_patchlevel) = @_;
In this line, change the value “my ($supported) = 0;” to “my ($supported) = 1;”.
When you repeat the process, you will see that it is done smoothly.
