How to Troubleshoot the Disordered IDs of the S5500 Enclosures of the N8000

Publication Date:  2012-07-18 Views:  129 Downloads:  0
Issue Description
During the N8300 deployment, the S5500 is used as the storage device of the background. When the disk enclosures and controller enclosure are powered on in sequence, the IDs of certain disk enclosures are disordered.
Alarm Information
None
Handling Process
Step 1  The S5500 storage device used by the N8000 cannot be logged in to from the Web interface and no command on the CLI can be used to change the disk enclosure ID.
Step 2  The ISM V1R1 of the N8000 cannot be used to modify the disk enclosure ID.
Step 3  Use the command line to enter the storage management interface of the S5500 and run the cleancofferdb command to clear DB information.
Step 4  Power off all disk enclosures but keep the controller enclosure powered on. The controller enclosure ID is 00.
Step 5  Power on the disk enclosure whose ID is to be set to 01, and wait until the ID turns 01.
Step 6  Power on other disk enclosures in sequence.
Root Cause
The power-on sequence of the disk enclosures is different and the IDs are allocated based on the power-on sequence. As a result, if the disk enclosures are not placed as planned, the IDs are disordered.
Suggestions
Perform the preceding operations only during deployment rather on in-service devices.
