Replace a Drive on a PA-5200 Series Firewall

Learn how to replace a drive on a PA-5200 Series firewall.
The PA-5200 Series firewalls have two solid-state drives (SSDs) used for system files and system logs and two hard-disk drives (HDDs) used for network traffic log storage. Each drive pair is in a RAID 1 array so that if a drive fails, you can replace the failed drive (using the same model drive) without service interruption. The system drives are labeled SYS 1 and SYS 2 and the log drives are labeled LOG 1 and LOG 2.
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.
The procedures to replace a system drive (SSD) and a log drive (HDD) are different.

Replace a Log Drive on a PA-5200 Series Firewall

The following procedure describes how to replace a failed log 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.
In a high availability (HA) configuration, if one log drive fails (or if both log drives fail) in the active firewall, the firewall enters the non-functional HA state and fails over. If the firewall is not in an HA configuration and one log drive fails, the firewall continues to operate. If both log drives fail in a non-HA configuration, the firewall continues to operate but it does not log network traffic and you cannot commit the configuration until there is at least one functioning log drive.
Depending on the size of the drive, it may take several hours for the new disk to be formatted and synced.
  1. Identify the failed drive and determine the drive model by running the following operational command to view the
    status
    and
    model
    fields:
    admin@PA-5220>
    show system raid detail
    The following output shows that the
    Log1
    drive failed and that the model number of that drive is
    ST2000NX0253
    . The system log also shows an error that indicates which drive failed (Log1 or Log2).
    Disk Pair Log Available Status clean, degraded Disk id Log1 Present model : ST2000NX0253 size : 1907729 MB status : failed Disk id Log2 Present model : ST2000NX0253 size : 1907729 MB status : active sync
  2. Remove the failed drive from the RAID 1 array configuration. In this example, run the following command to remove the
    Log1
    drive from the array:
    admin@PA-5220>
    request system raid remove log1
  3. Press the ejector button on the drive carrier to release the carrier handle and gently pull the handle toward you to remove the carrier and drive.
    The illustration shows how to remove a system (SYS) drive. The procedure to remove a log drive is the same.
  4. Remove the replacement drive from the packaging and determine the drive model. You will compare this model number with the model number of the failed drive to determine which replacement procedure to use in 7.
  5. Install the replacement drive in the drive carrier.
    1. Remove the replacement drive from the antistatic bag and place it on an antistatic surface. Place the failed drive next to the replacement drive with the connectors facing the same direction.
    2. Remove the four screws that hold the failed drive in the carrier and remove the drive from the carrier.
    3. Install the replacement drive in the carrier and secure it using the four screws you removed from the failed drive.
    The illustration shows an SSD system drive and an HDD log drive; the procedure to swap the drive is the same for both.
  6. Install the carrier with the replacement drive:
    1. Ensure that the drive carrier lever is in the open position; if it is not, press the ejector button on the drive carrier to release the lever and pull it out until it is fully open.
    2. Slide the carrier assembly into the empty drive bay until it is about 1/4” (.64cm) from being fully inserted.
    3. Before fully inserting the carrier, ensure that the lever attaches to the locking mechanism on the firewall and then close the lever to seat the carrier.
  7. Choose from the following two installation procedures based on your findings in 4:
    • If the replacement drive is the same model number as the failed drive, continue to 8.
    • If the replacement drive is a different model number than the failed drive, continue to 9.
  8. Same model replacement drive only) Add the replacement drive (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 LOG 1 drive to the array:
      admin@PA-5220>
      request system raid add log1
      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. This is because the system will recognize that a drive was missing and it will automatically reformat the newly inserted drive and will add it to the array.
    2. Periodically view the RAID status until you see that
      Disk Pair Log
      shows
      Available
      , the status shows
      clean
      , and the status for each drive shows
      active sync
      status. To view RAID status, run the following command:
      admin@PA-5220>
      show system raid detail
      The following output shows that both log drives are in the
      active sync
      state:
      Disk Pair Log Available Status clean Disk id Log1 Present model : ST2000NX0253 size : 1907729 MB status : active sync Disk id Log2 Present model : ST2000NX0253 size : 1907729 MB status : active sync
  9. Different model replacement drive only) Add the replacement drive (that is a different model than the failed drive) to the RAID 1 array:
    When you initiate the copy command as described in the following steps, logging stops and you cannot view logs until the copy is complete and the disk pair shows
    Available
    .
    1. (Optional)
      Suspend the firewall with the failed drive if it is the active firewall in an HA configuration.
      The firewall will fail over when the copy process in this procedures starts but you can choose to Verify Failover or manually suspend the firewall with the failed drive before you continue.
    2. Copy the data from the other drive in the RAID 1 array to the replacement drive. In this example, run the following command to copy the data from the
      Log2
      drive to the
      Log1
      drive:
      admin@PA-5220>
      request system raid copy from log2 to log1
    3. Run the following CLI command to view the status of the copy:
      admin@PA-5220>
      show system raid detail
      Periodically run this command until the copy is complete and the
      Disk Pair Log
      shows
      Available
      .
      At this point, the
      Log2
      drive shows
      not in use
      because the drive models are not the same.
      Disk Pair Log Available Status clean, degraded Disk id Log1 Present model : ST2000NX0999 size : 1907729 MB status : active sync Disk id Log2 Present model : ST2000NX0253 size : 1907729 MB status : not in use
    4. Replace the other drive in the array so the drive models in the array are the same. In this example, physically remove the Log2 drive, remove it from the carrier, and then install the second replacement drive in the carrier. 9.e shows how to swap drives in a carrier.
    5. Add the second replacement drive to the RAID 1 array. In this example, run the following command to add the Log2 drive to the array:
      admin@PA-5220>
      request system raid add log2
      The system automatically starts to configure the new drive to mirror the other drive in the RAID 1 array.
    6. Periodically view the RAID status until you see that the
      Disk Pair Log
      shows
      Available
      and both drives show
      active sync
      status. To view RAID status, run the following command:
      admin@PA-5220>
      show system raid detail
      The following output shows that both drives are in the
      active sync
      state:
      Disk Pair Log Available Status clean Disk id Log1 Present model : ST2000NX0999 size : 1907729 MB status : active sync Disk id Log2 Present model : ST2000NX0999 size : 1907729 MB status : active sync

Replace a System Drive on a PA-5200 Series Firewall

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.
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.
In a high availability (HA) configuration, if one system drive fails (or if both system drives fail) in the active firewall, the firewall enters the non-functional HA state and fails over. If the firewall is not in an HA configuration and one system drive fails, the firewall continues to operate. If both system drives fail in a non-HA configuration, you will need to replace the systems drives and restore the firewall configuration from a recent configuration backup.
  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-5220> 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-5220>
    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-5220> 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. Press the ejector button on the drive carrier to release the carrier handle and gently pull the handle toward you to remove the carrier and drive.
  5. 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 7.
  6. Install the replacement drive in the drive carrier.
    1. Place the failed drive next to the replacement drive with the connectors facing the same direction.
    2. Remove the four screws that hold the failed drive in the carrier and remove the drive from the carrier.
    3. Install the replacement drive in the carrier and secure it using the four screws you removed from the failed drive.
      The illustration shows an SSD system drive and an HDD log drive; the procedure to swap the drive is the same for both.
  7. Install the replacement drive in the firewall.
    1. Ensure that the drive carrier lever is in the open position; if it is not, press the ejector button on the drive carrier to release the lever and pull it out until it is fully open.
    2. Slide the replacement drive and carrier assembly into the empty drive bay until it is about 1/4” (.6cm) from being fully inserted.
    3. Before fully inserting the drive carrier, ensure that the lever attaches to the locking mechanism on the firewall and then close the lever to seat the carrier.
  8. Choose from the following two installation procedures based on your findings in 5:
    • If the replacement drive is the same model number as the failed drive, continue to 9.
    • If the replacement drive is a different model number than the failed drive, skip to 10.
  9. 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-5220>
      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-5220>
      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
  10. 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-5220>
      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 (see 6). 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-5220>
      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-5220>
      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
