Remove a faulty drive from the RAID array

Before you remove a faulty storage drive from your system, you should identify the faulty drive and remove it from the 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. Show the current 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 RAID array includes both storage drives as members. Note the serial number for the faulty drive and in which bay it is installed.
  4. Change to config mode.
    config
    The CLI prompt changes to include
    (config)
    .
  5. Remove the faulty drive from the RAID array.
    system raid remove drive ssd2
    A summary similar to this example displays:
    appliance-1(config)# system raid remove drive ssd2 status Remove of RAID SSD2 initiated. [11084.434517] md/raid1:md121: Disk failure on nvme1n1p3, disabling device. [11084.434517] md/raid1:md121: Operation continuing on 1 devices. [11084.449528] md/raid1:md122: Disk failure on nvme1n1p4, disabling device. [11084.449528] md/raid1:md122: Operation continuing on 1 devices. [11084.464098] md/raid1:md123: Disk failure on nvme1n1p5, disabling device.

[11084.492509] md/raid1:md127: Operation continuing on 1 devices. status Remove of RAID SSD2 initiated.
Now you can physically remove the drive and replace it with the new one that you received from F5. You do not have to power down the system before you remove the drive.
