Collecting physical disk data

You can use the Collect Physical Disk Data option to collect log sense data from all the physical disks on your storage array. Log sense data consists of statistical information that is maintained by each of the physical disks in your storage array. Your Technical Support representative can use this information to analyze the performance of your physical disks and for troubleshooting problems that may exist.

1. In the AMW, perform one of these actions:
   • To collect data from all of the physical disks in the storage array, select Monitor > Health > Collect Physical Disk Data > All Physical Disks.
   • To collect data from a single physical disk that is selected in the Hardware tab, select Monitor > Health > Collect Physical Disk Data > Selected Physical Disks.
   The Collect Physical Disk Data window is displayed.
2. Enter a name for the physical disk data filename in Specify filename or click Browse to navigate to a previously saved file to overwrite an existing file.
   The suffix *.bin is added to the file automatically if you do not specify a suffix for the file.
3. Click Start.
   The physical disk data collection is completed and saved at the location that you entered.
4. Click OK.
