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 29.
• There is a constant scraping or grinding sound when you access the hard
drive. See "Getting Help" on page 253.

Troubleshooting Loss of Communication

"Troubleshooting Array and Expansion Enclosure Connections" on page 247.

Troubleshooting External Connections

• Verify that the cables are connected to the correct ports before
troubleshooting any external devices. For the location of 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.
