Description
This document helps the user verify that the RAID controllers in the NAS array are online and active. This is not meant to be a complete document to troubleshoot problems but instead to help identify problems with the backend RAID controllers.


Steps to Follow
The document lists out the the basic checks that need to be done on the different NAS backend controllers modules before contacting Sun[TM] Support.

5210:
The NAS server contains the Raid controller unlike the other NAS products.The LCD in the front will display (R12 Ctlr failure) in case of a RAID controller failure. Also check the LEDs on the front panel and also the rear panel.

Front Panel:
System status - One LED on front panel and one at rear corner
Colour : Green or amber
Off = POST in progress or system stop
Green steady on = no fault
Green blinking = degraded
Amber steady = critical or non-recover

CPU 1 and 2 fault
function: Identify CPU failure
Location: Back corner of processor socket on main board
Amber On = fault

Rear Panel:
POST LEDs (four) Multicolor (Red/Green/Amber)
Function: To help diagnose power-on self test (POST) failures, a set of four bi-color diagnostic LEDs is located on the back edge of the server Main Board. These LEDs are visible through holes in the rear panel. Each of the four LEDs can have one of four states: Off, Green, Red, or Amber.

5310:
Check the lights on the front of the module. A green light indicates a normal
status; an amber light indicates a hardware fault.

On the drive faceplate, there are 2 leds - Drive active les and drive fault led
Drive active - steady green - no data is bein processed.
flashing green - data is being processed.
Drive fault - Steady amber - drive fault
flashing amber - locate function

Check on any visible amber leds on the controllers.
LED 9 at the rear of the is the fault led. Its normal status is OFF. If there is a problem, it is ON. Color - Amber
Led 11 at the rear is the Expansion port bypass led. Normal status is Off. If there is a problem is it ON. Color - Amber

Check for the Tray ID settings. Each enclosure must have a unique ID.

5320
Check for any visible amber leds on the CSM1 (Model 2882) modules or CSM2 ( Model 3992) modules. Refer to documentation for details.

CSM1 trays:
The Tray ID switch enables you to assign each module a unique tray ID,
which is required for proper operation of the storage array. The settings for each digit (X10 and X1) in the Tray ID range from 0 through 7. Recommended unique ID numbers range from 01 through 77.

It is recommended that CSM1 5300 RAID EU tray have Tray ID 00 and then for each expansion unit (EU) added be set with a Tray ID in sequential order. For example, RAID EU is set for 00, the first EU is set for 01, the second EU is set for 02, and so on.

CSM2 trays:
The CSM2 uses two LEDs to display the Tray ID. The Tray ID LEDs are located above (bottom controller, 'B') or below (top controller, 'A') the Expansion Ports on the controller modules. The Tray ID LEDs for the ESM (EU) modules are located above (bottom ESM module) and below (top ESM module) the Reserved Expansion Ports. The Tray ID LEDs enable you to see what the assigned ID is for each module.This ID is unique to each tray. The controller modules Tray ID should come up as 85, but the acceptable range is 80 - 99. The ESM modules Tray ID range is 00 ? 79

Important: The mixing of CSM1 trays and CSM2 trays in the same array stack is NOT supported.

We can have up to two controller modules attached to a single NAS head, and up to four controller modules attached to a clustered NAS setup and still maintain High Availability. If you add more than two or more than four controller modules you will need to use a fibre switch to attach them to the NAS heads.
If you have two or more controllers attached to a NAS setup each controller's Tray ID should be 85, the default, but the acceptable range of Tray ID s that can come up is between 80 - 99 for CSM2 trays.

5220:
The 5220 is a single controller unit. Optional expansion units can be connected to the RAID controller. The 5220 is what is referred to as a simplex array due to the fact that it contains only 1 controller.

This array necessarily uses SATA drives.

The following configuration rules apply to the Sun StorageTek 5220 NAS appliance:
 - Only 1 Controller Tray is supported within the Sun StorageTek 5220 NAS system.
 - A partially populated controller tray is supported as an entry level option. (8 drive configuration minimum)
 - Partially populated expansion tray is supported. (8 drive configuration minimum)
 - Sun StorageTek 5310 EU-F expansion trays are not supported.
 - Mixing drives of different capacity within a tray is not allowed.
 - Mixing of trays of different drive capacity is allowed.
 - RAID sets in all trays are pre-configured.

Note applicable for all the NAS arrays.

In case a problem has been detected with the Raid controllers and you are unsure of the corrective action, then please contact Sun Support after collecting data as per <Document: 1005474.1>

Internal Comments
For internal purposes, use sunsolve.central to search for documents listed above.

Be aware of CR 6491533
Synopsis:4.21 B59 does not recognize any CSM2 RAID controller with Amethyst-3 F/W
The above bug caused the NAS OS to not be able to communicate effectively with the controller firmware.
This was fixed in the NAS OS version 4.20 M3 B1. Refer to the relevant patches for obtaining the patch.
