Tips For Troubleshooting SCSI Bus Parity Errors

Last week, some users encountered a SCSI bus parity error. This issue can occur due to a number of factors. We will discuss this below.

    SCSI DATA IN Bus Phase Parity Error

    Reason

    scsi bus parity error

    The most common cause of this annoyance is unapproved hardware. SCSI devices designed for the specialized PC niche do not meet the UNIX market requirements for high I/O speeds. Other possible causes for this problem include an incorrect power supply or power interruption and fluctuations. Possible data corruptionbut highly unlikely as this equality error prevents the transfer.

    Action

    Make sure all SCSI devices connected to the bus are Sun approved. Then make sure all cables are no longer than twenty feet and have experts verify that all SCSI connections are properly connected. If power surges are possible, purchase an uninterruptible power supply.

    Make sure that many of the SCSI devices in your RV are approved by Sun. So this

    SCSI Failure: Migration Reason “reset”

    Cause
    This message proves that the system sent data over the SCSI bus, but normally the data
    never reached the destination because none of the SCSI buses were reset. The most common cause of this condition is a SCSI target conflict. Data corruption is possible, although unlikely, as it interferes with data transfer.
    Action
    Make sure all wires and cables are less than twenty feet long and all SCSI connections
    are securely terminated. . Power supply If power surgesFor solutions related to this problem, buy a surge protector or an uninterruptible power supply.
    The machine’s internal file drive is usually a four SCSI target. Make sure external and secondary file drives are aligned on 1, pair or 0 and don’t conflict with each other.
    Also make sure tape drives are aligned on 4 or 5 and CD tape drives should not be 6 as they conflict with each other. with friend. others or readers. If such targeting of an internal drive is considered questionable, turn off the machine, remove all external hard drives, power up fully, and watch the probe start up from the PROM. scsi-all or probe-scsi
    command.
    If targeting a SCSI device is acceptable, the problem may be in the memory settings. 4 MB). . are in the lower banks, and smaller RAM (eg 1MB SIMM type chips) are typical of the upper
    banks.
    SPARC systems do not always support booting third-party discs,
    CDs mayt generate a similar error message from an unknown vendor. Check with your CD vendor for specific configuration requirements.
    Some third-party disk drives have a read-ahead cache that interacts with
    Solaris device drivers. In fact, make sure that all existing cache read-ahead features are disabled.

    I keep getting “SCSI bus parity errors” on our own 4GB external hard drive. Sometimes the house fits, sometimes it doesn’t. When a problem occurs, I get heaps or I/O errors. I tried xfs_repair (which will be in IRIX) but it failed to complete the disk scan.
