 How to replace a defective PSA7000 hard drive

The PSA7000 system comes with dual hard drives configured as RAID 1 (mirroring) in software.  The drives are labelled HDD1 and HDD2 and should NOT be removed without first performing the serial console RAID remove and add operations, since this is software RAID implementation.   The software has to be informed of what drive will be removed and added.

Note: Removing the drive without properly removing from software RAID could cause drive partition corruption.

Orderable and RMA-able SKU:  PSA7000-HDD-701
PSA7000 hard drives

Procedure in replacing a defective drive:

  1. Connect a serial console cable to the PSA7000 device.
  2. Identify the defective drive, either HDD1 or HDD2 (Physical check on Drive status indicator - Red status indicates bad drive or via admin UI status - see below *Drive Status description)
  3. From serial console, remove the defective drive from the RAID as follows:
  • Select Menu option: 4. System Operations
  • Select Menu option: 20. Manage RAID
  • A prompt appears: Are you sure you want to manage RAID? (y/n)
  • Enter y for the prompt.
  • Choose Menu option: 1. Remove Disk1 (if removing HDD1) or 2. Remove Disk2 (if removing HDD2).
This will detach the disk in the appropriate slot from software RAID.
  1. Press the release button on the drive tray of the defective drive. This extends the drive tray handle.
  2. Use the handle to pull the drive out of the chassis.
Warning: Except for short periods of time (swapping hard drives), do not operate the server with the hard drives empty. The hard drive tray must have a hard drive or dummy drive installed to not interfere with system cooling.
  1. Find the replacement hard drive.
  2. Slide the drive tray into the empty slot in the chassis.
  3. Close the drive tray handle until it clicks into place.
  4. From serial console, add the defective drive from the RAID as follows:
  • Select Menu option: 4. System Operations
  • Select Menu option: 20. Manage RAID
  • A prompt appears: Are you sure you want to manage RAID? (y/n)
  • Enter y for the prompt.
  • Choose Menu option: 4. Add Disk1 (if adding HDD1) or 2. Add Disk2 (if adding HDD2).
This will attach the disk in the appropriate slot to the software RAID and should start the mirroring process.
Do not remove any drive until mirroring process is completed.
  1. Check the status of RAID and individual disks from the Web UI go to System > Platform.  The status of the disks and RAID are displayed as follows:
Hard drive status

Drive status description:
  • "Active" – The drive is active
  • "Missing" – The drive is missing
  • "Failed" –  The (RAID) drive has failed.
  • "Reconstructing" – RAID is reconstructing drive.
