3ware Raid Ecc Error

Contents

The 3ware RAID controller supports SMART monitoring, whereby the individual drives automatically monitor certain parametric information such as error rates and retry counts.This type of monitoring may be able to predict This may be due to a failed or missing sensor. An incomplete unit is a unit in which the 3ware RAID controller is unable to detect one or more drives. This error can be caused by unrecoverable drive errors. http://theblackinkproject.com/ecc-error/3ware-error.html

During this test the Battery Backup Unit cannot backup the 3ware RAID controller. Action: You should replace the 3ware RAID controller. See your enclosure documentation or contact your enclosure manufacturer to make sure you are following proper operating procedures. 8028 Enclosure temp unknown Event Type: Warning Cause: Applies only to the 9690SA permalinkembedsavegive gold[–]hateexchangeatheist, unless restoring backups[S] 0 points1 point2 points 2 years ago(1 child)Is this something you have to schedule outside the setup of an array, i assumed it would handle that part for http://serverfault.com/questions/332935/what-does-3wares-tw-cli-mean-by-a-degraded-disk-vs-ecc-error

3ware Degraded Drive

An enclosure is now accessible to the 9690SA RAID controller. Action: Reinstall the battery pack. 005C Battery is weak Event Type: Warning Cause: The Battery Backup Unit periodically evaluates the health of the battery and its ability to backup the 3ware Action: None required. 8001 Enclosure fan error Event Type: Error Cause: Applies only to the 9690SA controller. If the unit is non-redundant a unit file system check is recommended.

This indicates that the Battery Backup Unit must be replaced. 049h Battery temperature is normal The Battery Backup Unit measures and evaluates the battery pack temperature on a continuous basis. Action: None required. 0045 Battery voltage is low Event Type: Warning Cause: The battery pack voltage being monitored by the Battery Backup Unit has fallen below the warning threshold. I've had WAY too many punctured RAID arrays. Tw_cli Ignoreecc In some cases, however, this may be your only alternative for recovering as much data as possible from a unit that has become degraded.

During the evolution of the 3ware product line, the format of the Drive Configuration Block (DCB) has been changed to accommodate new features. This AEN is posted to the host when this health check is started. 052h Battery health check completed The Battery Backup Unit evaluates periodically the health of the battery and its If the data becomes corrupted between the drive and the 3ware RAID controller (e.g., an intermittent cable connection) the 3ware RAID controller detects this as a UDMA CRC or cable error. http://titan.physx.u-szeged.hu/opt/3ware/3DM2/help/en/AEN_0026.html If the unit remains incomplete, replace the missing or dead drives and initiate a rebuild. 0007 Initialize completed Event Type: Information Cause: The 3ware RAID controller completed the “synching” background initialization

Drive insertion caused the unit to become operational again. Tw_cli Cheat Sheet Covered by US Patent. RAID 5 and 50. This can be due to a failing power supply or an unreliable power source.

Hard Drive Ecc Error

This message may be seen if error recovery operations initiated by the 3ware RAID controller are unsuccessful. The configuration parameters which are lost will then return to their default values. 3ware Degraded Drive It is recommended to use an uninterruptible power supply (UPS) to protect against power failures. 8037 Enclosure power off Event Type: Warning Cause: Applies only to the 9690SA controller. Tw_cli Start Rebuild However, LSI/3ware recommends that the drives instead be configured as single drives.

One of the enclosure power supplies is not working. Tw_cli U

Action: If this message occurs more than three times a day, collect the system logs and contact Technical Support. 0002 Degraded unit Event Type: Error Cause: An error was encountered and If the 3ware RAID controller cannot commit the data to the drive after it has acknowledged to the host, this message is posted. If an error is found, the controller will attempt to correct the error by reading the primary copy. Check This Out For redundant arrays, this typically means that dynamic sector repair would be invoked (see AEN 023h).

It is no longer cooling the enclosure.

Action: If applicable, replace the failed power supply. This can be due to a failing power supply. Action: Contact 3ware technical support. 004D Battery temperature is too high Event Type: Error Cause: The battery pack temperature being monitored by the Battery Backup Unit is too high. 3ware Rebuild Stuck An insufficient number of operating fans may lead to overheating of the components in the enclosure. 8003 Enclosure fan added Event Type: Information Cause: Applies only to the 9690SA controller.

p0 was a new drive i could not finish the rebuild with it because of ECC errors on the "good drive" # clears the ecc errors. # ./tw_cli /c0 rescan Issue The relavent output of /c0 show all is: Port Status Unit Size Blocks Serial --------------------------------------------------------------- p0 DEGRADED u0 931.51 GB 1953525168 5QJ07MAH p1 ECC-ERROR u0 931.51 GB 1953525168 5QJ0DCW9 p2 OK Alle Rechte vorbehalten.

Hard Disk Drives (HDD) Existing user? this contact form Internal operations such as Background Media Scan post this AEN whenever drive ECC errors are detected.

Bare Metal Image backups support Full and Incremental backups. Take steps to bring the operating environment back within the enclosure manufacturer’s specifications. When this occurs the Battery Backup Unit is still able to backup the 3ware RAID controller but it signals that the battery pack should be replaced soon. 059h Battery capacity is p1 is the "working drive." 0 LVL 7 Overall: Level 7 Linux 7 Disaster Recovery 1 Message Accepted Solution by:martin_21102009-05-04 martin_2110 earned 0 total points Comment Utility Permalink(# a24300102) This

However, because ATA drives can reallocate sectors on write errors, the rebuild failure is most likely caused by the source drive of the rebuild detecting a read error. I do have a secondary backup but it's not crispy fresh. If the voltage is too high to operate, this AEN will be posted to the user. Action: AMCC recommends running the test at least once every 6 months, if the measured battery capacity is longer than 120 hours.

The 3ware RAID controller then retries the failed command three times at the current UDMA transfer rate. See your enclosure documentation or contact your enclosure manufacturer for more details. While typical modern disk drives are designed to allow several hundred grown defects, special attention should be paid to any drive in an array that begins to indicate sector repair messages. Action: Review the list of events on the Alarms page for other entries that may give you an idea of why the migration failed (for example, a drive error on a

If it is desired to continue on error, you can set the Continue on Source Error During Rebuild policy for the unit on the Controller Settings page in 3DM. 005h Rebuild Action: Allow verify to complete to identify any possible data integrity issues. 002A Verify failed Event Type: Error Cause: Verification of a unit has terminated with an error. This AEN indicates that an unsupported drive was detected during rollcall or a hot add. Sucks , but a lesson hard learned that raid-5/6 are the evil when it comes to cost of raid-10 or RAID-ADG/10.

If the drive is not part of a redundant unit, then you will need to backup your data before replacing the drive. 0019 Drive removed Event Type: Warning Cause: A drive The consequence of continuing a rebuild when there is a source error is that there may be corrupt data in your rebuilt unit. Rebuilds are normally paused for ten minutes after a system first boots up and during non-scheduled times when scheduling is enabled. 03Ch Initialize paused This AEN will be sent when the Consistency checks are scheduled to run monthly where possible, patrol reads are enabled otherwise.

Edit. Will Windows have any problems recognizing the new array as the boot drive?
