Replace a System Drive in a PA-5450 MPC

Identify the failed drive and determine the drive model using the
show system raid detail
CLI command.
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.

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-5450> 
request system raid remove sys1
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-5450> show system raid detail

Ensure that you have access to an ESD work surface for placement of the Management Processor Card (MPC).
Put the provided ESD wrist strap on your wrist ensuring that the metal contact is touching your skin. Then attach (snap) one end of the ground cable to the wrist strap and remove the alligator clip from the banana clip on the other end of the ESD grounding cable. Plug the banana clip end into one of the ESD ports located on the back of the appliance before handling ESD sensitive hardware. For details on the ESD port location, see PA-5450 Back Panel.
Remove the MPC from card slot 7 of the appliance. See Replace a PA-5400 Series Management Processor Card (MPC) for details on removing the MPC.
Place the MPC on an ESD work surface. Detach your wrist strap’s ground cable from the ESD port on the appliance and securely attach the alligator clip to the new ESD surface.
Flip the MPC over and locate the two SSDs on the bottom surface of the card. Remove the retention screw for the SSD you intend to replace.

The plastic standoff becomes loose after the retention screw is removed. Do not lose the standoff as it is needed when installing the new SSD.
Gently pull the SSD away from its mating connector. Place the old SSD to the side.
Slide the new SSD into the vacant mating connector. Ensure that the SSD aligns with the plastic standoff on the MPC.
Fasten the retention screw back into place at a torque of 4 in-lbs.
Exceeding a torque of 4 in-lbs will damage the equipment.

Before re-installing the MPC, plug the banana clip end of your ESD wrist strap into one of the ESD ports located on the back of the appliance.
Slide the MPC back into slot 7. See Install a PA-5400 Series Firewall Management Processor Card (MPC) for more information.
