RAID Statistics

RAID statistics are available to assist an administrator in assessing the status of the service platform RAID array, including each physical drive. The information within the RAID statistics screen is polled by the service platform from the RAID controller hardware, then forwarded to the WiNG operating system.

RAID controller drive arrays are available within NX 7510 and NX 95XX models only. However, they can be administrated on behalf of a profile by a different model service platform or controller.

For information on setting the service platform drive array configuration as well as the diagnostic behavior of its member drives, refer to RAID.

To view RAID statistics:

  1. Select the Statistics menu from the Web UI.
  2. Expand the RF Domain node.
  3. Select Wireless Controller .
  4. Select RAID from the left-hand side of the UI.
    The Statistics → Controller → RAID screen displays.
    Click to expand in new window
    The Status field displays the following information:
    Size

    Lists the size of the RAID drive array. The size is the total physical memory space available on the two physical drives comprising the active RAID controller.
    State

    Displays whether the drive array is currently in an optimal operation state or degraded, and in need of administration to perform diagnostics and perhaps prepare a standby drive for hot spare replacement.
    Alarm Enabled

    Displays whether the RAID alarm has been enabled to sound the service platform's chassis alarm upon detection of a RAID controller degradation event. The RAID alarm is enabled by default.
    Refer to the Last Check field to assess the time, progress and results of the RAIS array's most recent consistency check:
    Date

    Lists the date and time of the RAID controller's most recent consistency check on the integrity of the drive array.
    Result

    Displays true for a successful RAID array consistency check and false for a failed consistency check. A false indication would trigger the service platform's chassis alarm if RAID alarm is enabled.
    Progress

    Displays the progress of an in process consistency check in both percentage completed and minutes utilized (for example, 78%/116min).
    Use the Physical Drives field to assess the RAID array's drive utilization and whether the drives are currently online:
    Slot

    Lists RAID array's drive slot utilization. Since there is only one RAID array controller reporting status to the service platform, its important to know if other drive slots house hot spare drives available as additional resources should one of the dedicated drives fail.
    State

    Displays whether a physical slot within the RAID array has a drive installed, and whether the drive is currently online.
  5. Select Refresh at any time to update either the screen's statistic counters to their latest value.
