Re: allle RAID Partitionen weg und nun?
Hallo, @JürgenL: Es stimmt natürlich, das es nicht am OS liegt! Ich wollte nur nicht in der Linux- Liste ein Loblied auf Windoof anstimmen => war also nicht ganz ernst gemeint...Sorry
Leider hat der Kontroller intern kein Log (so weit ich das beurteilen kann). Es handelt sich um einen 3ware 8006-2 (2 Kanal SATA1) Kontroller ohne BatteryBackupUnit, der schon 4 Jahre Dauerbetrieb auf dem Buckel hat. Auf die Platten kommt man gar nicht mehr drauf! Also sollte dort ein Log gespeichert sein, dann komme ich dort nicht ran!

AEN Messages The AEN messages issued by the ATA RAID controller when an error is detected are summarized in the table below. Descriptions of each are provided at the end of the table.

Soft resets are normal at driver load and unload time. If the ATA RAID controller fails to respond to the device driver within a reasonable amount of time, the device driver may issue a soft reset to the ATA RAID controller and retry the command packet. AEN 002h AEN_DEGRADED_UNIT An error has been encountered and the array is operating in degraded (nonredundant) mode.The user should replace the bad drive as soon as possible and initiate a rebuild. AEN 003h AEN_CONTROLLER_ERROR The ATA RAID controller has encountered an internal error. Please contact 3ware customer support. AEN_UNIT_NOT_ZEROED 02Fh AEN_UDMA_DOWNGRADE 021h AEN_SECTOR_REPAIR 023h AEN_SBUF_FAIL 024h AEN_LOST_CACHED_WRITE 025h AEN_DRIVE_ECC_ERROR 026h AEN_DCB_XSUM_ERROR 027h AEN_DCB_BAD_VERSION 028h AEN_VERIFY_STARTED 029h AEN_VERIFY_FAILED 02Ah AEN_VERIFY_DONE 02Bh AEN_SECTOR_OVERWRITE 02Ch AEN_RBLD_SOURCE_ERROR 02Dh AEN_DRIVE_NOT_SUPPORTED 030h AEN_QUEUE_FULL 0FFh Table 1: AEN Error Messages Message Value Troubleshooting: Problems and Solutions 102 3ware Escalade ATA RAID Controller User Guide AEN 004h AEN_REBUILD_FAIL The ATA RAID controller was unable to complete a rebuild operation. This error can be caused by drive errors on either the source or the destination of the rebuild. However, due to ATA drives ability to reallocate sectors on write errors, the rebuild failure is most likely caused by the source drive of the rebuild detecting some sort of read error. The default operation of the ATA RAID controller is to abort a rebuild if an error is encountered. If it is desired to continue on error, the Ignore errors on rebuild radio button can be checked prior to initiating a rebuild. AEN 005h AEN_REBUILD_DONE The ATA RAID controller has successfully completed a rebuild. The completion of the rebuild changes the state of the array from rebuilding to OK. The data is now redundant. AEN 006h AEN_INCOMP_UNIT At power on initialization time, the ATA RAID controller performs a “rollcall” of all drives attached to the card. After detection of the drives, the ATA RAID controller then uses an internal algorithm to logically connect drives that belong to the same array. If after rollcall a member of an array is not found, the INCOMPLETE UNIT AEN is sent. Examples of incomplete units are as follows: ■ 4 drive RAID 5 with 1 drive missing. ■ 2 drive RAID 1 with 1 drive missing. Replacing the missing or dead drive and initiating a rebuild will change the state of the array from an incomplete unit to OK. AEN 007h AEN_INIT_DONE The ATA RAID controller has completed the initialization sequence and performs the initialization step at array creation time of RAID levels 1, 10 and 5. For RAID 5, the data on the array is read and the resultant parity is written to the parity area on the array. For RAID 1 and 10, one half of the mirror is copied to the other half (mirrors are synchronized). AEN 008h AEN_UNCLEAN_SHUTDOWN The ATA RAID controller has the ability to detect if the system has been shutdown via the standard shutdown mechanism of the operating system (clean shutdown). If the system loses power or is reset without going through the normal shutdown procedure, it is possible that the data on a redundant array may be out of synchronization. The unclean shutdown detection will detect Screen display messages www.3ware.com 103 this case and force the array to enter the rebuilding state. This has the effect of synchronizing the array back to a fully redundant state. To prevent unclean shutdowns, the user should always go through the normal shutdown procedure for the operating system in use and use an uninterruptible power supply (UPS) to prevent unclean shutdowns due to sudden power loss. AEN 009h AEN_APORT_TIMEOUT The ATA RAID controller has a sophisticated recovery mechanism to handle various types of failures of a disk drive. One such possible failure of a disk drive is a failure of a command that is pending from the ATA RAID controller to complete within a reasonable amount of time. If the ATA RAID controller detects this condition, it notifies the user, prior to entering the recovery phase, by displaying this AEN. Possible causes of APORT time-outs include a bad or intermittent disk drive, power cable or ATA interface cable. AEN 00Ah AEN_DRIVE_ERROR As part of the recovery mechanism of the ATA RAID controller, various drive failures can be detected and if possible corrected. One such drive failure is when the drive indicates back to the ATA RAID controller that it was unable to complete a command. If the drive returns an error to the ATA RAID controller, the user is notified by this AEN. AEN 00Bh AEN_REBUILD_STARTED The ATA RAID controller notifies the user whenever it starts a rebuild. The rebuild start may be user initiated (by selecting the rebuild button in the 3DM Disk Management Utility) or it may be auto initiated by a hot spare failover. In either case, the user is notified of the event by this AEN. AEN 00Ch AEN_INIT_STARTED The ATA RAID controller notifies the user by this AEN whenever it starts an Initialization. Initialization occurs at array creation time. AEN 00Fh AEN_SMART_FAIL The ATA RAID controller supports S.M.A.R.T. Monitoring. whereby the individual drives automatically monitor certain parametric information such as error rates and retry counts. By monitoring this data, SMART may be able to predict a drive failure before it happens, allowing a user to schedule service of the array before it becomes degraded. The SMART status of each drive attached to the ATA RAID controller is monitored daily. If a failure of any drive is determined to be likely, the user is notified by this AEN. Troubleshooting: Problems and Solutions 104 3ware Escalade ATA RAID Controller User Guide AEN 02Eh AEN_REPLACE_DRIVE_TOO_SMALL The ATA RAID controller notifies the user by this AEN when the replacement drive capacity is smaller than required. The replacement drive must be equal to or greater capacity than the drive it's replacing. For more information refer to the Hint on page 32. AEN 02Fh AEN_UNIT_NOT_ZEROED The ATA RAID controller notifies the user by this AEN when verification fails because the array has not been initialized. This is normal for the first verification that occurs on a RAID 1 or RAID 10 array. AEN 021h AEN_UDMA_DOWNGRADE The ATA RAID controller communicates to the ATA disk drives through the Ultra DMA (UDMA) protocol. This protocol ensures data integrity across the ATA cable by appending a Cyclical Redundancy Check (CRC) for all ATA data that is transferred. If the data becomes corrupted between the drive and the ATA RAID controller (e.g., an intermittent cable connection) the ATA RAID controller detects this as a UDMA CRC or cable error. The ATA RAID controller then retries the failed command three times at the current UDMA transfer rate. If the error persists, it lowers the UDMA transfer rate (e.g., from UDMA 100 to UDMA 66) and retries another three times. This AEN is sent to the user when the ATA RAID controller lowers the UDMA transfer rate. Possible causes of UDMA CRC errors are intermittent or bad ATA interface cables or cable routing problems through electrically noisy environments (e.g., cables are too close to the power supply). AEN 023h AEN_SECTOR_REPAIR The ATA RAID controller supports a feature called dynamic sector repair to allow the unit to recover from certain drive errors that would normally result in a degraded array situation. For redundant arrays such as RAID 1, 10 and 5, the ATA RAID controller essentially has two copies of the users data available. If a read command to a sector on a disk drive results in an error, it reverts to the redundant copy in order to satisfy the host’s request. At this point, the ATA RAID controller has a good copy of the requested data in its cache memory. It will then use this data to force the failing drive to reallocate the bad sector, which essentially repairs the sector. When a sector repair occurs, the user is notified by this AEN. The fact that a sector repair AEN has been sent to the user is an indication of the presence of grown defects on a particular drive. 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. This may be an indication of a drive that is beginning to fail. The user may wish to replace the drive, especially if the number of sector repair errors exceeds 3 per month. Screen display messages www.3ware.com 105 AEN 024h AEN_SBUF_FAIL The ATA RAID controller, as part of its data integrity features, performs diagnostics on its internal RAM devices. Once a day, a non-destructive test is performed on the cache memory. Failure of the test indicates a failure of a hardware component on the ATA RAID controller. This AEN is sent to notify the user of the problem. AEN 025h AEN_LOST_CACHED_WRITE To improve performance, this ATA RAID controller features caching layer firmware. For write commands this means that it acknowledges it has completed a write operation before the data is committed to disk. If the ATA RAID controller can not commit the data to the media after it has acknowledged to the host, this AEN is posted to the user. Typically, the LOST CACHED WRITE notification would be an indication of a catastrophic failure of the drives in the array, such as loss of power to multiple drives in an array. AEN 026h AEN_DRIVE_ECC_ERROR This AEN may be sent when a drive returns the ECC error response to a ATA RAID controller command. The AEN may or may not be associated with a host command. Internal operations such as Background Media Scan post this AEN whenever drive ECC errors are detected. Drive ECC errors are an indication of a problem with grown defects on a particular drive. For redundant arrays, this typically means that dynamic sector repair would be invoked (see AEN 023h). For non-redundant arrays (JBOD, RAID 0 and degraded arrays), drive ECC errors result in the ATA RAID controller returning failed status to the associated host command. AEN 027h AEN_DCB_XSUM_ERROR The ATA RAID controller stores certain configuration parameters on a reserved area of each disk drive called the Drive Configuration Block (DCB). As part of power-on initialization, the ATA RAID controller performs a checksum of the DCB area to ensure consistency. If an error occurs, please contact 3ware technical support. The drive’s DCB has been corrupted. AEN 028h AEN_DCB_BAD_VERSION During the evolution of the Escalade product line, the format of the DCB has been changed to accommodate new features. The DCB format expected by the ATA RAID controller and the DCB that is written on the drive must be compatible. If an array that was created on a very old Escalade product is connected to a newer Escalade ATA RAID controller, this AEN is posted and the ATA RAID controller rejects the drive. Please contact 3ware technical support if this event occurs. Troubleshooting: Problems and Solutions 106 3ware Escalade ATA RAID Controller User Guide AEN 029h AEN_VERIFY_STARTED The ATA RAID controller allows the user to verify data integrity on an array.The verification functions for different RAID levels are as follows: ■ JBOD. Verify = Media Scan ■ RAID 0. Verify = Media Scan ■ RAID 1. Verify = Compare of Mirror Sides ■ RAID 10. Verify = Compare of Mirror Sides ■ RAID 5. Verify = Parity Data = User Data When the verification starts, this AEN is posted to the user. AEN 02Ah AEN_VERIFY_FAILED This AEN indicates that the data integrity verification function (see AEN 029h) has terminated with an error. For each RAID level being verified, this may mean: ■ JBOD. A single drive returned an error, possibly because of a media defect. ■ RAID 0. A single drive returned an error, possibly because of a media defect. ■ RAID 1. One side of the mirror does not equal the other side. ■ RAID 10. One side of the mirror does not equal the other side. ■ RAID 5. The parity data does not equal the user data. For JBOD and RAID 0, the most likely cause of the error is a grown defect in the drive. For out-of-synchronization mirrors, the error could be caused by improper shutdown of the array. This possibility applies to RAID 1, 10 and 5. A rebuild will re-synchronize the array. AEN 02Bh AEN_VERIFY_DONE This AEN indicates the data integrity verification function (see AEN 029h) was completed successfully. No errors were encountered. AEN 02Ch AEN_SECTOR_OVERWRITE If a read error is encountered during a rebuild and the user chooses to ignore the error, the sector in error is reallocated. The user is notified of the event by this AEN. Screen display messages www.3ware.com 107 AEN 02Dh AEN_RBLD_SOURCE_ERROR If an error is encountered during a rebuild operation, this AEN is generated if the error was on a source drive of the rebuild. Knowing if the error occurred on the source or the destination of the rebuild is useful for troubleshooting. AEN 030h AEN_DRIVE_NOT_SUPPORTED Escalade 8000 series Serial ATA Controller only support UltraUDMA-100/ 133 drives. This AEN indicates that an unsupported drive was detected during rollcall or a hot add. This AEN also could indicate that the Serial to Parallel converter was jumpered in the wrong place.

Hallo, Wir haben nun ein neues RAID aufgesetzt (natürlich mit neuen/anderen Platten) und das "3ware 3dm2" installiert. Leider sind die Einträge vom Tag des Vorfalles nicht mehr im Log. Es gibt i.ü. kleinere Fortschritte mit Hilfe der SystemRescueCD: mit "gpart" konnte zumindest die Cluster- Nummern der Datenpartition ermittelt/erraten (wie es so schön auf der Homepage des Tools heisst) werden. Nun habe ich aus diesen Daten die Partitionstabelle mit fdisk erstellt. Diese wird nun auch von Testdisk erkannt, aber der Datenzugriff funktioniert nur "bitweise" mit "formost" und "grep -oba 'suchname' /dev/sda". Da sind die Daten zu sehen, aber nicht zugeordnet oder gar auslesbar. Es geht im wesentlichen darum aus der zweiten Partition ein Verzeichnis auszulesen und dann auf der neuen Installation zu installieren. Nun brennen mir zwei Fragen unter den Nägeln: 1. wie bekomme ich die Partition wieder hin, oder 2. wie kann ich die Dateien aus dem Verzeichnis so auslesen, dass die teilweise fragmentierten Dateien zusammenhängen und als Datei abspeicherbar sind? Da die professionellen Datenretter 3 bis 5 Tage veranschlagt haben, haben wir eine gute Chance schneller zu sein... -- Mit freundlichen Grüßen Sebastian Reinhardt LMV Landmaschinenvertrieb- und Service GmbH Hauptstrasse 13 (OT Hartmannsdorf) 01762 Hartmannsdorf- Reichenau Geschäftsführer: Bernd Reinhardt Amstgericht: Dresden Handelsregisternummer: HRB 2574 Umsatzsteuer- Identnr.: DE 206/261/04100 Tel: +49 373 26 1567 Mobil:+49 172 357 3107 Fax: +49 373 26 1567 Mail: snr@lmv-hartmannsdorf.de Web: www.lmv-hartmannsdorf.de Hinweis: Nach aktueller Rechtslage ist das Versenden von unaufgeforderter Werbung strafbar!
