Handling Process
1. In the address box of Internet Explorer, enter the IP address of the PTL. Log in to the PTL. The default user name and password are admin and password.
2. Associate the PTL with the driver by performing operations according to arrows in the following figure.
3. After the preceding operations are complete, log in to the VTL Console. Choose Physical Resources > Rescan. In the dialog box that is displayed, select Discover New Devices and click OK.
4. In the Fibre Channel Devices area, check devices that have been detected. Robot arms and the driver can be detected.
Root Cause
The PTL is newly purchased. No settings are made on the PTL. Therefore, you need to log in to the PTL and associate the PTL with a driver on the PTL interface. By default, robot arms of the PTL are associated with a driver of the PTL. If you do not set a control path, robot arms of the PTL cannot be detected at a certain probability.
If a driver of the PTL connects to the VTL through an optical fiber, the VTL can detect robot arms of the PTL.
Suggestions
If the PTL is newly purchased, you are advised to associate the PTL with a driver.
