4 Configuration and Utilities Server Utilities HP utilities provide reporting functions that enable event-focused management and diagnostics. To install and run these utilities, refer to the server documentation. • Diagnostics Utility—This utility tests and verifies proper operation of the system hardware. If problems are found, the utility isolates failure(s) down to the replaceable part, whenever possible. When an operating system is installed with SmartStart Version 5.
Configuration and Utilities • Survey Utility—This utility gathers critical hardware and software information on servers running Microsoft Windows and Novell NetWare operating systems. If a significant change occurs between data-gathering intervals, the Survey Utility marks the previous information and overwrites the Survey text files to reflect the latest changes in the configuration.
Configuration and Utilities ROM Functions and Utilities Each MSA500 controller has a ROM that contains the controller firmware. Recovery ROM The Recovery ROM feature stores two complete firmware images in the ROM: one active image and one backup image. When the controller is powering up, it checks both firmware images to be sure they are valid. If either image is invalid, the system overwrites the invalid image with the valid image.
Configuration and Utilities Controller Firmware Auto Cloning In a redundant controller configuration, both controllers must execute the same version of firmware. During power up (or when a redundant controller is installed as a hot-plug procedure), the system compares the controller firmware versions. If the versions differ, the controller displays a user input message seeking to initiate Controller Firmware Auto Cloning.
Configuration and Utilities Selective Storage Presentation SSP is a controller firmware feature that enables the administrator to control access from multiple hosts to logical drives on the MSA500 system. The administrator selects which server host or hosts can access the stored data, restricting access as needed to assure data integrity and security. Each logical drive on the controller has an access control list that contains the IDs of the server host adapters that have access to the drive.
Configuration and Utilities Enabling SSP After choosing the configuration that best suits your needs, enable SSP with ACU Version 6.0 or later. Locate ACU on the SmartStart CD. For instructions, refer to the HP Array Configuration Utility User Guide on the Documentation CD. Array Configuration Utility ACU Version 6.
Configuration and Utilities Drives can be moved to other ID positions on the same array controller. You can also move a complete array from one controller to another, even if the controllers are on different servers or storage devices. Arrays on different controllers can also be moved to another controller. Before moving drives, observe the following requirements: • No drives are failed, missing, or degraded. • The move does not result in more than 14 physical drives.
Configuration and Utilities Expanding and Extending Capacity CAUTION: Back up all data before removing drives or changing configurations. Failure to do so could result in permanent loss of data. Before moving drives and arrays, run ACU. Array Capacity Expansion is the addition of physical drives to an array that has already been configured.
Configuration and Utilities Array Diagnostics Utility ADU collects all possible information about the array controllers in the system and generates a list of detected problems. You can save this data to a file for analysis. In most cases, ADU provides sufficient information for troubleshooting procedures. To obtain ADU, download the utility from the HP website www.hp.
Configuration and Utilities Auto-configuration If no logical drives are configured, a CPQONLIN auto-configuration wizard appears and prompts you to select fault-tolerance information. CPQONLIN then configures arrays optimally for the selected fault tolerance.
Configuration and Utilities Custom Configuration Custom configuration allows you to create arrays and assign fault tolerance one array at a time. To custom configure an array: 1. Go to the Main Configuration View screen. 2. Highlight the controller, array, or logical drive to be configured. 3. Make a selection from the Options menu located on the right side of the screen.
Configuration and Utilities Drive Rebuild, Expand Priority, and Accelerator Ratio To set the drive rebuild priority, expand priority, or accelerator ratio for a controller: 1. Go to the Main Configuration View screen. 2. Highlight the controller. 3. Select the Controller Settings option listed below Controller Options. The Controller Settings screen appears. Drive Rebuild Drive rebuild occurs after a physical drive fails and is replaced.
Configuration and Utilities Priority Settings To set the drive rebuild priority: 1. Highlight the MSA500 controller. 2. Select the controller settings. — If you choose low priority for drive rebuild, drive rebuilding takes place when I/O to the drive is inactive. — If you choose high priority, drive rebuilding occurs faster, at the expense of normal I/O operations.
Configuration and Utilities Adding or Configuring Spare Drives When adding a spare drive to an array, there must be an unassigned drive or a drive already assigned as a spare on another array. You can assign a single spare to any number of arrays or assign separate spares. When you select Assign Spare Drive, only drives that qualify will appear (for example, only those spares that are large enough will appear).
Configuration and Utilities Drive status messages include: • Interim Recovery: The logical drive is operating, but a failed drive has not been replaced. Replace drive as soon as possible. • Ready for Recovery: The logical drives are queued for recovery. This status is displayed when another logical drive is already rebuilding or expanding. • Rebuilding: The array is operating and rebuilding a replacement drive or an online spare, if one was assigned.
Configuration and Utilities NOTE: A failed status can occur on drives protected by fault tolerance if two or more physical drives fail concurrently. Some status messages are available without pressing the F3 key. For example, on the Main menu, the FAILED status appears next to the logical drive that has failed. EXPANDING and REBUILDING appear next to the array in which the activity is occurring.
Configuration and Utilities Optimizing Array Controller Performance To improve system performance, keep these tips in mind before creating NetWare volumes or partitions: • If you selected a fault-tolerance option, such as mirroring or distributed data guarding, when using the System Configuration Utility, do not select mirroring while using INSTALL.NLM. The fault-tolerance capabilities of the MSA500 controller provide performance improvements and automatic data recovery features.

D Troubleshooting This appendix provides specific troubleshooting information for the HP MSA500 system. Use it to find details about startup and operation errors. For a list of error messages specific to this system, refer to Appendix C, “Display Messages.” For information on LEDs, refer to Chapter 1, “Component Identification.
Troubleshooting When the System Does Not Start WARNING: A risk of personal injury exists from hazardous energy levels. The installation of options and the routine maintenance and service of this product must be performed by individuals who are knowledgeable about the procedures, precautions, and hazards associated with equipment containing hazardous energy circuits. If the system does not start: 1. Be sure that the attached server and monitor are working properly. 2.
Troubleshooting 7. The controller display provides a “Startup Complete” message. Diagnostic Steps If the storage system does not power up, or powers up but does not complete POST, answer the questions in Table D-1 to determine the appropriate actions. The flow of questions reflects the usual flow of events during a power-up sequence. According to the answers you give, you are directed to the appropriate table in this section.
Troubleshooting Table D-2: Are the Power Supply/Blower Assembly LEDs Green? Answer Possible Reasons Possible Solutions No The power cords are not connected or AC power is not available. Be sure that the power cord is connected to the power supply. A power supply problem exists. The power supply may not be inserted properly, it may have a damaged connector, or it may have failed. Be sure that the power supply is undamaged and that the power supply is fully seated.
Troubleshooting Table D-3: Is the System Power LED Green? Answer Possible Reasons Possible Solutions No The Power On/Standby button has not been pressed firmly. Firmly press the power button. The power button/LED assembly has failed. A power supply problem exists. The power supply may not be inserted properly, it may have a damaged connector, or it may have failed. The system may have experienced a short. Controller firmware may be corrupted.
Troubleshooting Recovering from Hard Drive Failure CAUTION: Back up all data before removing drives or changing configurations. Failure to do so could result in permanent loss of data. Before moving drives and arrays, run ACU 6.0. The purpose of fault-tolerant configurations on the HP MSA500 controller is to protect against data loss due to drive failure.
Troubleshooting • Spare hard drive configuration guidelines include: — Always assign a spare to each individual array separately. — Always be sure that the capacity of the spare is greater than or equal to the capacity of any drive that it is intended to replace. — Always be sure that a spare assigned to multiple controllers is of greater or equal capacity to any drives in that array. NOTE: Only remove hard drives that have been failed or marked as degraded by the controller.
Troubleshooting Compromised Fault Tolerance Compromised fault tolerance commonly occurs when more physical drives have failed than the fault tolerance method can endure. In this case, the controller fails the logical volume and returns “unrecoverable disk” error messages to the host. Data loss is likely to occur. An example of this situation would be a RAID 5 logical drive, where one drive on an array fails while the controller is rebuilding another drive in the same array.
Troubleshooting 6. Replace any failed drives. 7. After the failed drives have been replaced, the fault tolerance may again be compromised. If so, cycle the power again, and if the #02 or #04 controller display message is displayed, press the right push button. This action re-enables the logical drive(s). Automatic Data Recovery Automatic Data Recovery is an automatic background process that rebuilds data onto a spare or replacement drive when another drive in the array fails.
Troubleshooting Failure of Automatic Data Recovery If the online LED of the replacement drive stops flashing during Automatic Data Recovery, two possible causes are: • The replacement drive is failed (amber failure LED illuminated or other LEDs not illuminated) and is producing unrecoverable disk errors. Remove and replace the failed replacement drive.
Troubleshooting Always perform disk drive replacement as soon as possible. In addition, all logical volumes on the same array as the drive being replaced should have a current valid backup. If another drive in the array fails while you are rebuilding a previously failed drive, fault tolerance is compromised and all data on the array is lost, with the following exceptions: • In a mirrored (RAID 1) configuration, failure of a drive that is not mirrored to any other failed drives.
Troubleshooting If a drive fails and you have hardware fault tolerance enabled, system operations continue. However, you should replace the drive as soon as possible to prevent failure of the array. If you do not replace the failed drive, the only option using CPQONLIN is to delete logical volumes. Do not delete logical volumes that contain valid data, or the data will be lost. To monitor the status of a drive recovery, select the logical drive on the Main Configuration screen and press F3.
Troubleshooting Hardware-Based Fault Tolerance 1. Identify and document which physical drive has failed. (On hot-plug drives in a ProLiant server or storage system, this is indicated by an amber drive failure LED on the drive tray.) Note the drive type and capacity. NOTE: Storage systems using hardware-based fault tolerance in NetWare cannot detect failure of a single physical drive. In this case, the data will still show as valid and accessible during the rebuilding process.
Troubleshooting 2. Failed hot-plug drives in a ProLiant server or storage system are identifiable by an amber LED on the drive tray. Record the location of the drive bay containing the failed physical drive. This is where the new physical drive must be inserted. 3. Choose one of the following methods: — If the failed drive is a hot-plug drive, go directly to step 4. — If the failed drive is not a hot-plug drive, schedule storage system down time, take the storage system offline, and power off the unit.
Troubleshooting 9. On the INSTALL.NLM Available Disk Drives menu, select the previously failed logical drive, which has now been repaired. The device information was recorded in step 1. For example: NWPA: [V503-A2-D1:0] Compaq SMART-2 Slot 8 Disk 2 NFT 10. Select the Delete Partition menu option. INSTALL.NLM may display several error messages. Since you will delete this partition, do not update any Volume Definition Table information. Continue until the partition has been deleted. 11. If INSTALL.
Troubleshooting The expansion process is illustrated in the following figure, where the original array (containing data) is shown with a dashed border, and the newly added drives are shown unshaded (they contain no data). The array controller redistributes the original logical drive over the enlarged array, using the same fault tolerance method. The unused capacity on the new (enlarged) array can then be used to create an additional logical drive, with a different fault tolerance setting if necessary.
