MD3400 and MD3420 Series SAS RAID Controller Module Item Component Function 1 16 Gbps FC IN port (4) Provides host-to-controller FC connection. 2 Seven segment display sequence Displays status or error codes for the storage array. 3 Controller power LED Lights green when controller power is on. Turns off when controller is not powered. 4 Controller fault LED Lights amber when controller fault is detected.
Table 5. Host Channel LED Link Rate Indications (continued) LED 1 LED 0 CommRate Off On 2 Gbps On Off 4 Gbps On On 8 Gbps RAID Controller Module—Additional Features Battery Backup Unit Each RAID controller contains a two-cell Lithium ion nanopolymer battery backup unit (BBU). It provides power to the RAID controller module in the event of a power outage. For information on removing and installing the BBU, see RAID Controller Module Backup Battery Unit .
Cache Functions and Features Cache Mirroring Cache mirroring function copies accepted host-write data from the primary controller to the partner controller. This action ensures that host-write data is safely mirrored to the partner controller before successful completion status is returned to the host. If a controller fails, the surviving controller safely retains all mirrored data. Cache mirroring is enabled by default.
Figure 9. SAS Cable 1. mini SAS connector 2. SAS cable 3. mini SAS HD connector Interoperability of 4 Gbps, 8 Gbps, and 16 Gbps Devices The FC standard specifies a procedure for speedy autodetection. If an 8 Gbps port on a switch or device is connected to a 4 Gbps port, it must negotiate down for the link to run at 4 Gbps. If there are two 16 Gbps ports on either end of a link, the negotiation runs the link at 16 Gbps if the link supports the required specifications.

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.
CAUTION: When handling static-sensitive devices, take precautions to avoid damaging the product from static electricity. NOTE: Before proceeding with this section, see Working With SFP Modules And Fibre Optic Cables in the Dell PowerVault MD3800f and MD3820f Series Storage Arrays Deployment Guide at dell.com/powervaultmanuals. NOTE: Equip yourself with antistatic protection and a replacement small form-factor pluggable (SFP) transceiver before replacing an SFP transceiver in the RAID controller module.
Based on the LED status, perform one of these actions: • • • If at least one of the FC IN LEDs for each port is on, go to step 11. Both the FC IN LEDs on an MD storage array RAID controller module enclosure for a particular port are off. Check that the SFP transceiver is installed correctly. Reinstall the SFP transceiver if necessary. NOTE: If the storage array is not in an Optimal status, click the Recovery Guru toolbar button in the Array Management Window to determine if any other actions are required.
• • External airflow is obstructed. The cooling fan module is removed or has failed. If the problem is not resolved, see Getting Help. Troubleshooting Expansion Enclosure Management Modules 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.
If the Array Status LED is Solid or Blinking Amber 1. In the AMW, select the Summary tab, and click on Storage Array needs attention. 2. Follow the listed procedures in the Recovery Guru(s) and wait for up to 5 minutes to check if the LED has turned blue. 3. 4. 5. 6. 7. 8. If following the Recovery Guru procedures does not solve the problem, complete the following procedure to further troubleshoot the array. Turn off the host server as appropriate.
5. 6. 7. 8. Turn on the expansion arrays and then the storage array and wait until the system is fully booted. Turn on the host server. Check the LEDs of all cabled ports. Replace the fibre optic cables of any port(s) where both LEDs are unlit. Reboot the host server. NOTE: You must turn off the host server before resetting the cables on the storage array or expansion enclosure. If the problem is not resolved, see Getting Help.
• • • • Processor(s) and heat sink(s) Memory modules Hard-drive carriers Hard-drive backplane 4. Ensure that all cables are properly connected. 5. Close the system. 6. Run the appropriate diagnostic test. For more information, see Using System Diagnostics. If the tests fail, see Getting Help. Controller Failure 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.
PCI Errors The storage array firmware can detect and only recover from PCI errors when the RAID controller modules are configured for redundancy. If a virtual disk uses cache mirroring, it fails over to its peer RAID controller module, which initiates a flush of the dirty cache.
