Symptom
CHAP authentication is enabled for initiators on the DeviceManager and the automatic target reconnection is configured on Windows Server 2003. However, after CHAP authentication is disabled on the DeviceManager and the application servers are restarted, the application servers cannot be reconnected to the targets automatically.
Possible Causes
After CHAP authentication is disabled on the DeviceManager, CHAP authentication is not updated on the application servers, causing the application servers unable to access the storage system.
Procedure
Open Microsoft iSCSI Initiator on the application server.
Click the Persistent Targets tab. In the Select a Target list, delete the IP addresses of the iSCSI front-end ports on the storage system.
Click the Targets tab. In the Targets list, select the IP addresses of the iSCSI front-end ports on the storage device.
Click Log On.
The Log On to Target dialog box is displayed.
Select Automatically restore this connection when the system boots and click OK to save the settings. Restart the application server.
If the application server automatically reconnects to the targets after it is started up, the fault is rectified. Otherwise, keep the fault environment intact and contact technical support.
