User input messages User input messages indicate that the system has encountered a situation that allows user input. The user can select from a number of choices. If the user does not select one of the choices in a set amount of time, the system selects the default setting. These user input messages only occur during system power on, and not during runtime.
Message Type Description Action Yes = the volume is enabled (regardless of the issue.) The volume attempts to return to its normal operating state and the data is accessible. No = not selecting any option within the time-out period = the volume remains disabled. The volume stays in the failed state and the data is not be accessible. During this time, the user can attempt to fix the issue.
Message Type Description Action 10 FIRMWARE FLASH FAILED Error ROM flash failed. Download new firmware from the HP website and initiate the firmware update again. If the issue persists, contact HP support. 11 CLONING REFUSED SYSTEM HALTED Error A firmware mismatch was detected, message 07 CLONE FIRMWARE? '<'=NO, '>'=YES was displayed, and the user selected < for “No”. Firmware on the controllers must be updated to be the same.
Message Type Description Action 24 BAD SCSI BUS MODE NON-LVD DEVICE FOUND Error The MSA does not support SCSI Single Ended (SE) devices; it only supports SCSI Low Voltage Differential (LVD) devices. The MSA should be powered off and then all SCSI devices attached to it should be examined. Any SE devices found should be removed and replaced with LVD devices.
Message Type Description Action 32 CHASSIS NVRAM CONTENTS CORRUPTED Error The MSA has non-volatile memory on it that contains required information needed to operate. This non-volatile memory appears to be corrupted and the information is not valid. The MSA cannot continue to operate and halts. 40 INITIALIZING REDUNDANCY SUPPORT Informational Two array controllers are installed, and the they are attempting to enter redundant mode.
Message Type Description Action 44 REDUNDANCY FAILED MISMATCH HARDWARE Error Both array controllers must contain the same hardware for them to successfully enter redundant mode. The current array controllers do not contain the same hardware, possibly because one has an attached Fibre Channel daughter card and the other does not.
Message Type Description Action 48 REDUNDANCY HALTED FIRMWARE CLONED Informational Both array controllers must run the same version of firmware for them to successfully enter redundant mode. A process called firmware cloning has been successfully completed in order to make them both the same firmware level. The standby array controller is restarted automatically so they can attempt to achieve redundancy again.
Message Type Description Action 52 REDUNDANCY FAILED PCI BUS ERROR Error While either attempting to enter redundant mode or already operating in redundant mode, one of the array controllers encountered a PCI bus error on the communication channel used between the two array controllers. Redundancy is disabled at this time. If the MSA is currently involved in host I/O, remove the standby array controller, wait 10 seconds, and then reinsert it, ensuring that it is fully seated in the chassis.
Message Type Description Action 60 NO CACHE MODULE FOUND Error The array controller requires at least one cache module in order to operate. Either one is not present or it has failed. Remove the failed array controller, either add a cache module or replace the failed one, wait 10 seconds, and then reinsert it, ensuring that it is fully seated in the chassis. Should the issue persist, contact HP support.
Message Type Description 67 CACHE HARDWARE TEMPORARILY DISABLED Informational The cache memory hardware has temporarily been disabled, typically because the battery is not charged or a capacity expansion operation is occurring. The cache automatically enabled once the condition has been corrected. 68 OBSOLETE CACHE DATA DELETED Informational Old data that no longer belongs to any current configured volumes was found in the cache memory at power up. This data has been deleted.
Message Type Description Action 72 CACHE ERROR IGNORE? <=NO, >=YES User input During power up, data was found in the cache that could not be flushed to the hard drives. The reason is either because the data does not belong to this array controller (the cache module was moved from a different array controller) or the cache data is partial (the rest of the data is in another cache module that was removed from the array controller). This error could occur if cache modules are moved improperly.
Message Type Description Action 81 SMART DRIVE ALERT BOX #, BAY Informational A SCSI hard drive may be close to failing. This was determined either by the hard drive firmware itself using SMART technology or by the array controller using monitor and performance testing. 82 DRIVE HOT ADDED BOX #, BAY Informational A SCSI hard drive has been added to the MSA chassis or attached external storage enclosure.
Message Type Description Action 89 INVALID CONFIG BOX #, BAY Error For the MSA1500, before using an attached MSA20, the MSA20 is checked to see if any hard drives contain configuration data from a source other than the MSA1500. If so, the enclosure is failed and this message is displayed. An MSA20 attached to an MSA1500 must be configured by the 1500.
Message Type Description Action 106 VOLUME # STATE WAITING TO REBUILD Informational The configured volume is waiting to start rebuilding data on a SCSI hard drive that replaces a previously failed drive. The rebuild may not have started yet because the array controller is already performing a rebuild on another configured volume. 107 VOLUME # STATE WAITING TO EXPAND Informational The configured volume is waiting to start a volume expansion operation.
Message Type Description Action 112 VOLUME # REBUILD FAILURE Error The rebuild operation on the configured volume has failed. If the volume is still operating in regenerative mode, remove the new SCSI hard drive that was added as a replacement for the original failed hard drive and replace it with a different new drive. 113 VOLUME # EXPANSION FAILURE Error The volume expansion operation on the configured volume has failed.
Message Type Description Action 123 TOO MANY VOLUMES DETECTED Error The array controller only supports a maximum of 32 configured volumes. More volumes than that were detected at power up. This typically occurs when migrating a set of volumes from one array controller to a different array controller that already has configured volumes on it. The migrated volumes have not been added. Remove the migrated volumes and run the Array Configuration Utility (ACU).
Message Type Description Action 151 BEACON OFF Informational The LEDs on the MSA and all connected hard drives are no longer blinking because the host-based application is no longer identifying or configuring this MSA. 201 ARRAY CONTROLLER TEMPERATURE OK Informational The temperature sensor on the array controller indicates that the temperature that was previously exceeding the normal operating range is now back within the range.
Message Type Description 301 RECOVERY ROM AUTOFLASH DONE Informational The array controller has successfully completed the process of copying the current active firmware image into the backup recovery ROM. 302 RECOVERY ROM AUTOFLASH FAILED Error The array controller failed to copy the current active firmware image into the backup recovery ROM. Recovery ROM support is disabled.
Message Type Description Action 306 FIRMWARE FLASH STARTED Informational The array controller in the MSA has started the firmware flash process. Do not turn off power to the system until it has completed. This could take several minutes. 307 FIRMWARE FLASH DONE Informational The array controller in the MSA has completed the firmware flash process. It is now safe to restart the MSA and begin using the new firmware.
Message Type Description Action 402 STORAGE BOX # FAN DEGRADED Error A fan in the specified storage enclosure is not operating at full efficiency. The fan may eventually fail. 403 STORAGE BOX # FAN HOT INSERTED Informational An fan in the specified storage enclosure has been hot-added. 404 STORAGE BOX # FAN HOT REMOVED Informational A fan in the specified storage enclosure has been removed.
Message Type Description Action 412 STORAGE BOX # EMU NOT RESPONDING Error An EMU in the specified storage enclosure is not responding to commands. 413 STORAGE BOX # EMU VERSION Informational The version of firmware running on the EMU. This is only displayed for the internal EMU of the MSA chassis. It is not displayed for externally connected storage boxes. 414 STORAGE BOX # HOT REMOVED Informational An external storage enclosure has been hot-removed from the back of the MSA.
Message Type Description Action 511 FIBRE CHANNEL SUBSYSTEM HARDWARE FAILURE Error The array controller's Fibre Channel subsystem has encountered a critical error during the power up sequence. Remove the failed array controller and its associated Fibre Channel module, reseat the Fibre Channel daughter card on the array controller, wait 10 seconds, then reinsert the Fibre Channel module and the array controller, ensuring that they are fully seated in their respective bays in the chassis.
Message Type Description Action 518 PERSISTENT MEM ENABLED Informational Persistent memory data has been successfully initialized. 519 PERSISTENT MEM DISABLED Informational Persistent memory data has not been successfully initialized. Some configuration data may not be available. 520 UNKNOWN I/O MODULE DETECTED Error The MSA cannot determine the type of I/O module installed in the bay. Do the following: 1.

When a device weighs more than 22.
WARNING! Verify that the AC power supply branch circuit that provides power to the rack is not overloaded. Overloading AC power to the rack power supply circuit increases the risk of personal injury, fire, or damage to the equipment. The total rack load should not exceed 80 percent of the branch circuit rating. Consult the electrical authority having jurisdiction over your facility wiring and installation requirements.
CAUTION: To properly ventilate the system, you must provide at least 7.6 centimeters (3.0 inches) of clearance at the front and back of the device. CAUTION: When removing or replacing a failed component, allow 30 seconds to pass before inserting a replacement component. This time is needed to allow the device to clear out the system registries. CAUTION: Schedule physical configuration changes during periods of low or no activity.
Determining whether a component is hot-pluggable Before removing any serviceable part, determine whether the part is hot-pluggable or non-hot-pluggable. • If the component is hot-pluggable, a power shutdown of the device is not required for replacement of the part. • If the component is not hot-pluggable, the device must be powered down. CAUTION: Be sure the replacement is available before removing a component or blanking panel from the chassis.
Connecting power to the MSA HP strongly recommends using the power cord shipped with the MSA. If using a different power cord, your power cord should be approved for use in your country. The power cord must be rated for the product and for the voltage and current marked on the electrical ratings label of the product. The voltage and current rating of the cord should be greater than the voltage and current rating marked on the product. In addition, the diameter of the wire must be a minimum of 1.
Applying power to the MSA Before applying power to the MSA, all components of the storage system must be installed and connected to the supported interconnect options. Hard drives should be installed in the enclosures so that they can be identified and configured at power up. The MSA and the other network components must be powered on in the following sequence: 1.
Removing power from the MSA CAUTION: System power to the MSA does not shut off completely with the power switch. The two positions of the front panel power switch should be considered as On and Standby, rather than On and Off. The standby position removes power from most of the electronics and the hard drives, but portions of the power supply and some internal circuitry remain active. • To remove all power from the system, you must disconnect the power cord from the storage system.
Removing or installing a Fibre Channel interconnect blank Before you begin CAUTION: • Before removing a component or blanking panel from an operational device, make sure that you have the replacement part available. Removing a component or blank impacts the airflow and cooling ability of the device. To avoid possible overheating, insert the new or replacement component within one or two minutes.

Replacing the SCSI I/O module CAUTION: The SCSI I/O module with an integrated EMU is not hot-pluggable. Before replacing the module, all I/O from the servers must be stopped and the MSA must be powered down. Before you begin CAUTION: • Before removing a component or blanking panel from an operational device, make sure that you have the replacement part available. Removing a component or blank impacts the airflow and cooling ability of the device.
Installing the component 1. Slide the replacement SCSI I/O module into the bay until it clicks into place. 15560 2. Reconnect all SCSI cables. NOTE: Ensure that all of the SCSI cable connectors are fastened tightly. Verifying proper operation After replacing the failed SCSI I/O module, verify that: • The module status LED is solid green. • No new error messages are displayed on the array controller LCD panel. Replacing the power button module CAUTION: The power button module is not hot-pluggable.
Verifying component failure Before replacing the power button module: • Verify that the module status LED is not illuminated or is flashing amber. • Check the array controller LCD display panel for error messages and take appropriate action. Removing the component 1. Review all warnings, cautions, and preparation procedures as detailed in Warnings and precautions. 2. Stop all access to and remove power from the MSA. For instructions, see Removing power from the MSA.
Installing the component 1. Slide the replacement power button module into the bay until it clicks into place. 2. Reinstall all hard drives in slots 10–14. CAUTION: To prevent data loss, each hard drive must be installed in the same slot from which is was removed. 3. Reinstall the MSA in the rack. 4. Reconnect he SCSI, Fibre Channel, and power cables. 5. Apply power to the MSA as instructed in Applying power to the MSA.

7 Enclosure and hard drive migrations This section describes the following: • Adding a new storage enclosure • Migrating existing enclosures • Moving hard drives or arrays NOTE: For the most up-to-date information on supported enclosures, see the MSA website. Adding a new storage enclosure New storage enclosures with unconfigured hard drives are hot-pluggable. Perform the following steps to attach and install a new enclosure to an existing MSA: 1. Install the new storage enclosure in the rack.
4. Attach SCSI cables to the MSA expansion SCSI connectors. 5. Attach the SCSI cables to the expansion storage enclosures. 6. Attach the power cords to the power supplies at the rear of the enclosures. 7. Power on each enclosure and wait for it to complete its startup routine. 8. Power on the MSA array controller system using the power button on the front of the system. 9. Wait for the MSA to complete its startup routine. 10. Power on the host servers and allow them to boot. 11.
8 Capacity expansion and extension Array expansion is the addition of physical hard drives to an array that has already been configured. The capacity of these added physical hard drives may then be added to an existing LUN on the array or configured into a new LUN. LUN extension is the enlargement of an existing LUN after the corresponding array has undergone capacity expansion. Expansions and extensions are performed through the ACU or MSA-CLI.
Capacity expansion and extension
9 Hard drive failures and faulted LUNs The purpose of fault-tolerant array configurations is to protect against data loss due to hard drive failure. Each RAID configuration has inherent limitations on the number of hard drive failures that it can tolerate. If the fault-tolerance level of a particular LUN or array configuration is exceeded, the array will be locked from any further I/O.
• RAID 6 configurations can tolerate simultaneous failure of two hard drives in the array. Compromised fault tolerance Each RAID configuration has inherent limitations on the number of physical hard drive failures that it can tolerate. If more hard drives fail than the fault-tolerance method allows, fault tolerance is compromised. When the MSA determines that the fault tolerance of a LUN is compromised, the LUN is taken offline and subsequent I/O requests are rejected.
b. Make copies of important data, if possible. c. Replace any failed hard drives and allow the Automatic Data Recovery (ADR) process to rebuild the data onto replacement drives. d. After failed hard drives have been replaced, fault tolerance may again be compromised. If so, power cycle the system, and if the #02 or #04 ENABLE VOLUME LCD message is displayed, press the right push button to re-enable the LUNs. 7. If using the ACU: a. Open the ACU and highlight the faulted LUN (shown with a red drive symbol.
• When RAID 6 (ADG) is used, two drives can fail simultaneously (and be replaced simultaneously) without data loss. • If the offline drive is a spare, the degraded drive can be replaced. • Do not remove a failed second hard drive from an array until the first failed or missing hard drive has been replaced and the rebuild process is complete. (When the rebuild is complete, the online LED on the front of the hard drive stops blinking.
Failure of another drive during rebuild If a non-correctable read error occurs on another physical drive in the array during the rebuild process, the Online LED of the replacement drive stops blinking and the rebuild abnormally terminates. If this situation occurs, restart the server and the storage system. The system may temporarily become operational long enough to allow recovery of unsaved data. In any case, locate the faulty drive, replace it, and restore data from backup.
