Hardware replacement procedures

  • Hot-swapping an internal disk drive
    When a disk drive fails, the storage system logs a warning message to the system console indicating which disk drive failed, the fault LED on the operator display panel illuminates, and the fault LED on the failed disk drive illuminates. You can hot-swap a disk drive while the system remains powered on.
  • Replacing the caching module
    You must replace the caching module in the controller module when your system registers a single AutoSupport (ASUP) message that the module has gone offline; failure to do so results in performance degradation.
  • Replacing the NVMEM battery
    To replace an NVMEM battery in the system, you must remove the controller module from the system, open it, replace the battery, and close and reinstall the controller module.
  • Swapping out a power supply
    Swapping out a power supply involves turning off, disconnecting, and removing the old power supply and installing, connecting, and turning on the replacement power supply.
  • Replacing the controller module
    You must verify the following prerequisites for the replacement procedure.
  • Replacing a DIMM
    You must replace a DIMM in the controller module when your system registers an increasing number of correctable error correction codes (ECC); failure to do so causes a system panic.
  • Replacing the boot media
    The boot media stores a primary and secondary set of system (boot image) files that the system uses when it boots. Depending on your network configuration, you can perform either a nondisruptive or disruptive replacement.
  • Replacing the real-time clock battery
    You replace the real-time clock (RTC) battery in the controller module so that your system’s services and applications that depend on accurate time synchronization continue to function.
  • Replacing the chassis
    To replace the chassis, you must move the power supplies, hard drives, and controller module or modules from the impaired chassis to the new chassis, and swap out the impaired chassis from the equipment rack or system cabinet with the new chassis of the same model as the impaired chassis.
