Unable to Log in to Storage Devices Due to Disabled CHAP Authentication

Publication Date:  2012-07-22 Views:  122 Downloads:  0
Issue Description

The CHAP authentication is enabled for initiators in the ISM, while the targets are configured to be reconnected automatically on the AS installed with Windows. However, the targets are not reconnected automatically after the AS is restarted.

Product and version information:
  • S2600
  • S5000 series
  • The OS of the AS is Windows 2003
Alarm Information
None
Handling Process
  1. On the AS, check and record the IP addresses of iSCSI host ports that fail to reconnect to the targets automatically.
  2. Open the Microsoft iSCSI Initiator software on the AS.
  3. Click the Persistent Targets tab.
  4. Locate the entries for the IP addresses recorded in step 1 in the Select a Target list box, and then delete them.
  5. Click the Targets tab.
  6. Locate the entries for the IP addresses recorded in step 1 in the Targets list box.
  7. Click Log On... to open the Log On to Target dialog box.
  8. Select Automatically restore this connection when the system boots and click OK to save the settings, and then restart the AS.
  9. If the AS automatically reconnects to targets after it is restarted, the fault is removed. Otherwise, keep the fault environment intact and contact technical support.
Root Cause

By checking the settings of the Microsoft iSCSI Initiator software, setting errors are found.

Suggestions
  • The universally unique identifier (UUID) of the file system can be used to avoid the sequential error of mounting iSCSI disks.
  • The iscsi-mountall script supplied with the Linux iSCSI Initiator is defective, in which the line for disk detection needs to be commented out.
  • The execution sequence for startup in Linux should be boot.local -> S08iscsi -> S22myrctest.
