Degraded Physical Disk Channel

What Caused the Problem?

A physical disk channel status was set to Degraded either because of excessive I/O errors, or at the instruction of a technical support representative for diagnostic or other support reasons. It is important to correct this failure as soon as possible. The physical disks are still operational, but a level of path redundancy has been lost. If the other channel to the physical disks fails, then the physical disks themselves may fail. The Recovery Guru Details area provides specific information you will need as you follow the Recovery Steps.

Important Notes

You must contact your technical support representative to correct this failure. DO NOT attempt to fix this problem yourself.
If a Loss of Path Redundancy failure is also being reported in the Summary area of the Recovery Guru, you MUST fix this failure first; otherwise, you could lose both paths to the physical disks.
DO NOT manually set the physical disk channel to Optimal until you have consulted with your technical support representative.

Recovery Steps

1	Check the Summary area of the Recovery Guru to see if there is a Loss Of Path Redundancy failure being reported. If this failure is being reported, fix it first before going to step 2.
2	From the Support tab, click the Gather support information link. In the Specify file field, enter a name for the file to be saved or browse to a previously saved file if you want to overwrite an existing file. Use the convention "filename.zip" for the name of the file. (The suffix .zip will be added to the file automatically if you do not specify one.) You may also specify another physical disk and directory if you want to save the file in a location other than the default.
3	Click the Start button.
4	After the process completes, click the OK button.
5	Contact your technical support representative and indicate that a "Degraded Physical Disk Channel" problem is being reported. The support representative will have you send the file you saved in the steps above and wait for further instruction.
