Add a replacement drive to the RAID array

After you have physically replaced a faulty drive with a new one from F5, you add the replacement drive to the software RAID array.
  1. Connect to the system using a management console or console server.
    The default baud rate and serial port configuration is 19200/8-N-1.
  2. Log in to the command line interface (CLI) of the system using an account with admin access.
    When you log in to the system, you are in user (operational) mode.
  3. View the status of the drives.
    show system raid raid-array-status
    A summary similar to this example displays:
    appliance-1# show system raid raid-array-status ARRAY ARRAY NAME BAYID SERIAL NUMBER MEMBER STATUS SIZE ---------------------------------------------------------- ssd1 0 PHLJ912345PK1P0FGN true ok 684.7G ssd2 1 PHLJ912345Q61P0FGN true undefined 684.7G
    The status of the replacement drive is
    undefined
    , and the serial number should match that of the replacement drive.
    If after a few seconds, you do not see the replacement drive in the disk summary, the drive might not be seated properly. If this occurs, remove and reinsert the drive.
  4. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  5. Add the replacement drive to the array.
    system raid add drive ssd2
    A summary similar to this example displays:
    appliance-1(config)# system raid add drive ssd2 status Add RAID SSD2 initiated.
    The array status for the new drive should change to
    replicating
    , and the STAT LED should change to solid green. The replication process typically takes between 15 and 45 minutes.
  6. Return to user (operational) mode.
    end
  7. Verify that the new drive is added to the RAID array.
    show system raid raid-array-status
    A summary similar to this example displays:
    appliance-1# show system raid raid-array-status ARRAY ARRAY NAME BAYID SERIAL NUMBER MEMBER STATUS SIZE ---------------------------------------------------------- ssd1 0 PHLJ912345PK1P0FGN true ok 684.7G ssd2 1 PHLJ967890Q61P0FGN true ok 684.7G
  8. Check if there are any active system alarms.
    show system alarms
    If there are any active alarms, they display in a summary similar to this example:
    appliance-1# show system alarms ID RESOURCE SEVERITY TEXT TIME CREATED -------------------------------------------------------------------------------------------- 66306 lcd ERROR Fault detected in LCD module 2021-11-11 10:11:28.602630317 UTC
