Issue Description

After the storage device is restarted, the Error dialog box appears and prompts Fail to communicate with the device or Fail to authenticate when certain operations are performed in the ISM installed on the maintenance terminal.

Product and version information:
  • S2600
  • S5000 series
Alarm Information
None
Handling Process
  1. Click the Physical tab in the ISM, and select the storage device node that is inoperable.
  2. Choose Configuration > Stop Monitoring to open the Warning dialog box.
  3. Type yes in the Warning dialog box, and then click OK to stop monitoring on the storage device.
  4. Choose System > Discover Device to open the Discover Device dialog box.
  5. Enter the information of the storage device in the Discover Device dialog box, and then try to discover the storage device again.
Root Cause

It is found that the ISM has already performed Discover Device on the storage device; however, the ISM doesn't perform Discover Device again after restarting the storage device, causing the Error dialog box to appear and prompt Fail to communicate with the device or Fail to authenticate when performing certain operations.

Suggestions

This fault can also be removed by restarting the ISM to discover devices again.
