Replace a System Drive in a PA-5400 Series Firewall

Learn how to replace a drive on a PA-54 00 Series firewall.
The PA-5410, PA-5420, and PA-5430 firewalls use a pair of solid-state drives (SSDs) to store the PAN-OS system files, system logs, and network traffic logs. If one of these drives fail, you must replace it to restore functionality to the firewall.
When ordering a replacement drive from Palo Alto Networks or your reseller, you receive two drives. This ensures that if the replacement drive is not the same model as the failed drive, you can install two new matching drives. If the replacement drive model is the same as the failed drive, you need only replace one failed drive and can store the second drive as a spare. For firewalls in an HA pair, there is no requirement that the drive sizes match between the paired systems.
If you replace a system drive with a different model drive, you must boot the firewall into the Maintenance Recovery Tool (MRT) to copy data between drives. In a high availability (HA) configuration, suspend the firewall with the failed drive as described in this procedure.
The replacement drive ships with a factory default PAN-OS image with the default configuration. After you install the new drive, you will either need to copy configuration data from one drive to the other or obtain a backup configuration that you saved from the failed firewall to restore your configuration.
To avoid injury to yourself or damage to your Palo Alto Networks® hardware or the data that resides on the hardware, read the Product Safety Warnings.
The following procedure describes how to replace a failed system drive. There are two scenarios: one where the replacement drive is the same model as the failed drive and one where the replacement drive is not the same model.
  1. Identify the failed drive and determine the drive model.
    When the system drives are functioning normally, all system drive partitions show both drives with the status
    clean
    . If a system drive fails, the
    Overall System Drives RAID status
    shows
    degraded
    , one or more failed partition array shows
    clean
    ,
    degraded
    , and one of the drives will be missing (Sys1 or Sys2).In this example, the output from the
    show system raid detail
    command shows that the drive model is
    MICRON_M510DC_MT
    , the panlogs partition shows the status
    clean
    ,
    degraded
    , and drive
    Sys1
    is missing from the panlogs array; together, these indicate that you need to replace the Sys1 drive.
    admin@PA-5420> show system raid detail Overall System Drives RAID status degraded ----------------------------------------------------------------------------- Drive status Disk id Sys1 Present (MICRON_M510DC_MT) Disk id Sys2 Present (MICRON_M510DC_MT) ----------------------------------------------------------------------------- Partition status panlogs clean, degraded Drive id Sys2 active sync maint clean Drive id Sys1 active sync Drive id Sys2 active sync sysroot0 clean Drive id Sys1 active sync Drive id Sys2 active sync sysroot1 clean Drive id Sys1 active sync Drive id Sys2 active sync pancfg clean Drive id Sys1 active sync Drive id Sys2 active sync panrepo clean Drive id Sys1 active sync Drive id Sys2 active sync swap clean Drive id Sys1 active sync Drive id Sys2 active sync
  2. Remove the failed drive from the RAID 1 array. In this example, run the following command to remove drive
    Sys1
    from the array:
    admin@PA-5420>
    request system raid remove sys1
  3. Confirm that the failed drive is removed from all partitions. In the following output of the
    show system raid detail
    , you see that
    drive id Sys1
    is now missing from all partitions.
    admin@PA-5420> show system raid detail Overall System Drives RAID status degraded ----------------------------------------------------------------------------- Drive status Disk id Sys1 Present (MICRON_M510DC_MT) Disk id Sys2 Present (MICRON_M510DC_MT) ----------------------------------------------------------------------------- Partition status panlogs clean, degraded Drive id Sys2 active sync maint clean, degraded Drive id Sys2 active sync sysroot0 clean, degraded Drive id Sys2 active sync sysroot1 clean, degraded Drive id Sys2 active sync pancfg clean, degraded Drive id Sys2 active sync panrepo clean, degraded Drive id Sys2 active sync swap clean, degraded Drive id Sys2 active sync
  4. Disconnect power from the firewall, then remove the AC power cords.
  5. Unscrew the captive screw on the system drive cover on the front side of the firewall. See PA-5400 Series Front Panel for help locating the system drive cover.
  6. Pull the SSD module out of the firewall.
  7. Remove the replacement drive from the packaging, determine the drive model, and place it on an antistatic surface. Then compare this model number with the model number of the failed drive to determine which replacement procedure to use in Step 9.
  8. Slide the replacement SSD module onto the rails and gently push it into the firewall. Re-fasten the captive screw until the module is secure in the appliance.
  9. Choose from the following two installation procedures based on your findings in Step 7:
    • If the replacement drive is the same model number as the failed drive, continue to Step 10.
    • If the replacement drive is a different model number than the failed drive, skip to Step 11.
  10. (
    Same model replacement drive only
    ) Add the replacement drive (one that is the same model as the failed drive) to the RAID 1 array:
    1. Add the replacement drive to the RAID 1 array. In this example, run the following command to add the SYS 1 drive to the array:
      admin@PA-5420>
      request system raid add sys1
      If the replacement drive was previously used in a different Palo Alto Networks firewall, include the
      force
      option in this command to force the system to reformat the drive and add it to the array. If you reboot the firewall after removing the failed drive from the array, the force option is not required. Because the firewall recognizes that a drive is missing and it will automatically reformat the newly inserted drive and adds it to the array.
    2. Periodically view the RAID status until you see that the
      Overall System Drives RAID status
      shows
      Good
      , all partitions show
      clean
      , and both drives show
      active sync
      . To view RAID status, run the following command:
      admin@PA-5420>
      show system raid detail
      Do not reboot the firewall until all partitions are ready; otherwise, the system drives may become out of sync and the firewall will not boot.
      Overall System Drives RAID status Good --------------------------------------------------------------------------- Drive status Disk id Sys1 Present (MICRON_M510DC_MT) Disk id Sys2 Present (MICRON_M510DC_MT) --------------------------------------------------------------------------- Partition status panlogs clean Drive id Sys1 active sync Drive id Sys2 active sync maint clean Drive id Sys1 active sync Drive id Sys2 active sync sysroot0 clean Drive id Sys1 active sync Drive id Sys2 active sync sysroot1 clean Drive id Sys1 active sync Drive id Sys2 active sync pancfg clean Drive id Sys1 active sync Drive id Sys2 active sync panrepo clean Drive id Sys1 active sync Drive id Sys2 active sync swap clean Drive id Sys1 active sync Drive id Sys2 active sync
  11. (
    Different model replacement drive only
    ) Add the replacement drive (one that is a different model than the failed drive) to the RAID 1 array:
    1. Connect a serial cable from your computer to the Console port on the firewall and connect to the firewall using terminal emulation software that is configured to use 9600-8-N-1 settings.
    2. (
      Optional
      ) Suspend the firewall with the failed drive if it is the active firewall in an HA configuration.
      The firewall fails over when you boot into the Maintenance Recover Tool (MRT) as described in the following step but you can choose to Verify Failover or manually suspend the firewall that contains the failed drive.
    3. Reboot the firewall with the failed drive into the MRT by running the following command:
      admin@PA-5420>
      debug system maintenance-mode
    4. Press
      Enter
      on
      CONTINUE
      and then navigate to
      RAID
      and press
      Enter
      again.
    5. Navigate to the Migrate Drive section and select the drive to migrate. In this example, select
      Migrate drive Sys2 -> Sys1
      to initiate the process of copying the system data from the Sys2 drive to the Sys1 replacement drive.
    6. After migration is complete, remove the other system drive. In this example, remove the Sys2 drive.
    7. Press
      Esc
      to go back to the main menu and then press
      Enter
      on
      Reboot
      .
    8. After the firewall boots PAN-OS, replace the other drive in the array so the drives in the array are the same model. In this example, first remove the Sys2 drive from the carrier and install the second replacement drive (one that is the same model as Sys1) into the carrier. Then, install the second replacement drive in slot Sys 2.
    9. Add the second replacement drive to the RAID 1 array. In this example, run the following command to add drive Sys2 to the array
      admin@PA-5420>
      request system raid add sys2
      If the replacement drive was previously used as a system drive in a different Palo Alto Networks firewall, include the
      force
      option in this command to force the system to reformat the drive and add it to the array. If you reboot the firewall after removing the failed drive from the array, the force option is not required. Because the firewall recognizes that a system drive is missing and automatically reformats the newly inserted drive and adds it to the array.
      The system automatically starts to configure the new drive to mirror the other drive in the RAID 1 array.
    10. Periodically view the RAID status until you see that the
      Overall System Drives RAID status
      shows
      Good
      , all partitions show
      clean
      , and both drives show
      active sync
      . To view RAID status, run the following command:
      admin@PA-5420>
      show system raid detail
      Do not reboot the firewall until all partitions are ready; otherwise, the system drives may become out of sync and the firewall will not boot.
