Instructions

If multiple alerts are received for several different disks with the same message, check for the following:
 
  1. other alerts that may indicate / isolate where the issue is
  2. the status of enclosure I/O modules
  3. the cabling to the enclosures
  4. the status of I/O ports on the controllers that connect to the enclosures
 
For a Single Disk Alert:
Each disk should have two paths for I/O.  One of those paths for the disk indicated in the alert has become unavailable. 
To identify the physical location of the disk(s) and verify status:
 
  1. Go to Storage Tab in Dell Storage Manager
  2. Expand Disks / Disk Folder
  3. Look for the disk index number indicated in the alert.
  4. Record the enclosure number and enclosure position the disk is located
  5. Right click disk and choose ‘Show in Hardware Tab’
  6. Review status of ‘Bypass A Side’ and ‘Bypass B Side’
  • If both sides show ‘No’, the issue has cleared, acknowledge alert
  • If one of the sides show ‘Yes’, the disk still has one path available, contact technical support for additional help
