Subject: [PATCH] Fix iscsiadm op new report to cannort rename error
Since patched 9009-fix-default-file-corrupt.patch,
In order to solve the abnormal power failure during iscsiadm login,
the node configuration file is cleared, and the target
problem cannot be found after restarting.
The difference between automatically creating target nodes
and the target nodes through the discovery process is not considered.
The automatically created taregt node s is an regual file,
but a directory through the discovery process.
It is incorrect to rename a regual file as a directory
1) Automatically created
