Configuration and utilities 61 Survey Utility is installed with every SmartStart-assisted installation or can be installed through the HP PSP. ROM functions and utilities Each MSA500 G2 controller has a ROM that contains the controller firmware. Smart Components for ROM Flash To update the firmware on the server, controller, or hard drives, use Smart Components. These components are available on the Firmware Maintenance CD.
HP StorageWorks MSA500 G2 Storage System User Guide 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 storage 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 63 IMPORTANT: During incompatible version cloning, the storage system does not reset the updated controller if the controller is operating and processing I/O. In this case, the storage system does not enter redundant mode and provides an informational message on the controller display. To configure redundancy, cycle the storage system power.
HP StorageWorks MSA500 G2 Storage System User Guide Array Configuration Utility ACU is a browser-based utility with the following features: • Runs as a local application or remote service • Supports online array capacity expansion, logical drive extension, assignment of online spares, and RAID or stripe size migration • Suggests the optimum configuration for an unconfigured system • Provides different operating modes, enabling faster configuration or greater control over the configuration option
Configuration and utilities 65 • The controller is not reading from or writing to any of the spare drives in the array. • The controller is not running capacity expansion, capacity extension, or RAID or stripe size migration. • The controller is using the latest firmware version (recommended). If you want to move an array to another controller, you must also consider the following additional limitations: • All drives in the array must be moved at the same time.
HP StorageWorks MSA500 G2 Storage System User Guide – If an 86 controller display message appears, drive positions were changed successfully and the configuration was updated. – If a 121 controller display (no volumes) message appears, power down the system immediately to avoid data loss, and return the drives to their original positions. 6. Check the new drive configuration by running ORCA or ACU.
Configuration and utilities 67 The expansion process is illustrated in the following figure, in which the original array (containing data) is shown with a dashed border and the newly added drives (containing no data) are shown unshaded. The array controller adds the new drives to the array and redistributes the original logical drives over the enlarged array one logical drive at a time. This process liberates some storage capacity on each of the physical drives in the array.
HP StorageWorks MSA500 G2 Storage System User Guide NetWare Online Array Configuration Utility (CPQONLIN) The NetWare Online Array Configuration Utility, also called CPQONLIN, is an NLM for configuring drive arrays without shutting down the storage system. CPQONLIN also provides information about the status of drives attached to the MSA500 G2 controller. It indicates drive failure, expansion, or waiting for expansion or rebuild (queued). Before loading CPQONLIN.
Configuration and utilities 69 Customizing the chassis name The Chassis Name field is available for a user-defined, customized name that helps define the connection between the server HBA and the storage system controller. This field prevents the user from relying entirely on the adapter ID of the host controller for identification purposes. Enabling chassis identification The Identify Chassis field enables the user to set the Chassis Blink Status.
HP StorageWorks MSA500 G2 Storage System User Guide Accelerator ratio The MSA500 G2 controller has an onboard cache called an Array Accelerator, which performs both write-posting and read-ahead caching. The setting in CPQONLIN determines the amount of memory allocated to the read and write caches. For example, if the Accelerator Ratio is set to Read 75%:Write 25%, 75% of Array Accelerator cache is dedicated to read-ahead cache and 25% is dedicated to the write-posting cache.
Configuration and utilities 71 Migrating RAID level and stripe size online Using CPQONLIN, you can modify both the RAID level and stripe size of an existing logical drive while online. To migrate a drive: 1. Select the drive setting option under the logical drive menu for the drive you intend to modify. 2. Select the new RAID level and/or stripe size from the choices presented. If the new settings are valid, the migration begins when you save the changes.

HP StorageWorks MSA500 G2 Storage System User Guide b. The blowers start up. c. The 2-Port or 4-Port Shared Storage Module LED flashes green. 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 the following table to determine appropriate actions based on the symptoms observed. According to the answers you give, you are directed to the appropriate table.
Troubleshooting 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. 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 is fully seated. The system backplane may need to be replaced.
HP StorageWorks MSA500 G2 Storage System User Guide Is the controller display providing messages? Answer Possible Reasons Possible Solutions No The controller may not be inserted properly, it may have a damaged connector, or it may have failed. Be sure that the controller is undamaged and is fully seated. Be sure that all pins on connectors and components are straight. Contact an authorized service provider for assistance.
Troubleshooting • ADU lists all failed drives. • CPQONLIN identifies failed drives in a NetWare environment. 79 For additional information about diagnosing hard drive problems, refer to the HP ProLiant Servers Troubleshooting Guide. CAUTION: Sometimes, a drive that has previously been failed by the controller may seem to be operational after the system is powercycled or (for a hot-pluggable drive) after the drive has been removed and reinserted.
HP StorageWorks MSA500 G2 Storage System User Guide One example of a situation in which compromised fault tolerance may occur is when a drive in an array fails while another drive in the array is being rebuilt. If the array has no online spare, any logical drives in this array that are configured with RAID 5 fault tolerance will fail. Compromised fault tolerance can also be caused by non-drive problems, such as a faulty cable or temporary power loss to a storage system.
Troubleshooting 81 Factors to consider before replacing hard drives • In systems that use external data storage, be sure that the server is the first unit to be powered down and the last to be powered back up. Taking this precaution ensures that the system does not erroneously mark the drives as failed when the server is powered up. • If you set the SCSI ID jumpers manually: – Check the ID value of the removed drive to be sure that it corresponds to the ID of the drive marked as failed.
HP StorageWorks MSA500 G2 Storage System User Guide • Do not remove a second drive from an array until the first failed or missing drive has been replaced and the rebuild process is complete. (The rebuild is complete when the Online LED on the front of the drive stops blinking.) These cases are the exceptions: – In RAID ADG configurations, any two drives in the array can be replaced simultaneously.
Troubleshooting • The rotational speed of the hard drives • The availability of drive cache • The brand, model, and age of the drives • The amount of unused capacity on the drives • The number of drives in the array (for RAID 5 and RAID ADG) 83 Allow approximately 15 minutes per gigabyte for the rebuild process to be completed. This figure is conservative, and newer drive models usually require less time to rebuild.
HP StorageWorks MSA500 G2 Storage System User Guide Drive failure in a NetWare environment Use CPQONLIN to identify and monitor drive failure status in a NetWare environment. Failed drives or interim recovery mode If a drive fails and hardware fault tolerance is enabled, operation continues. Do the following: 1. Replace the drive as soon as possible. 2. Select a logical drive. 3. Press the F3 key to monitor to the status of drive recovery.
Troubleshooting 85 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. Handling disk drive failures If the MSA500 G2 controller was configured with hardware fault tolerance, complete the following steps after a disk drive failure: 1. Determine which physical drive failed.
