Troubleshooting a Damaged Array

CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product.

1Ensure that the following components are properly installed:

•Hard drives

•RAID controller module s

•Power supply/cooling fan modules

•Control panel

•Backplane

2Ensure that all the cables are properly connected and that there are no damaged pins in the connectors.

3Run diagnostics available in Dell™ PowerVault™ Modular Disk (MD) Storage Manager software. In the AMW, select a component in the Physical pane of the Physical tab. Select Advanced→ Troubleshooting→ Run Diagnostics.

If the test fails, see "Getting Help" on page 253.

Troubleshooting RAID Controller Modules

Conditions

Certain events can cause a RAID controller module to fail and/or shut down. Unrecoverable ECC memory or PCI errors, or critical physical conditions can cause lockdown. If your RAID storage array is configured for redundant access and cache mirroring, the surviving controller can normally recover without data loss or shutdown.

Typical hard controller failures are detailed in the following sections.
