Troubleshooting Storage Array Startup Failure
If your system halts during startup, check if:
• The array emits a series of beeps.
• The array fault LEDs are lit. See "RAID Controller Modules" on page 31.
• There is a constant scraping or grinding sound when you access the hard
drive. See "Getting Help" on page 265.
Troubleshooting Loss of Communication
For information about troubleshooting loss of communication, see
"Troubleshooting Array and Expansion Enclosure Connections" on page 259.
Troubleshooting External Connections
• Verify that the cables are connected to the correct ports before
troubleshooting any external devices. To locate the back-panel connectors
on your array, see Figure 3-1.
• Ensure that all the cables are securely attached to the external connectors
on your array.
