Disk Drive Replacement

Last modified
<< PrevNext >>

This page explains how a user can remove and replace a malfunctioning or failed disk drive for a StorSimple system. The procedure to swap a disk drive is identical irrespective of where the drive is located - in the head unit or the EBOD enclosure.

The detailed process of swapping a failed disk drive is explained in the following sections:

Disengaging the Anti-Tamper Lock

This procedure explains how the Anti-Tamper locks can be engaged or disengaged prior to replacing the disk drives. The anti-tamper locks are fitted in the Drive Carrier handles and are accessed through the small cutout in the latch section of the handle. Drives are supplied with the locks set in the locked position.
  • Carefully insert the lock key (a T10 screwdriver) provided by StorSimple into the cutout in the handle and into its socket. Note that if the anti-tamper lock is activated, the "red" indicator is visible in the aperture.
  • Rotate the key counterclockwise until the “red” indicator is not visible in the aperture above the key. 
  • Remove the key.
  • The disk drive can now be removed.
Follow the steps in reverse to engage the lock.

Removing a Disk Drive

 Note.png Note: Your StorSimple appliance supports a RAID-10 configuration. This implies that it can operate normally with one failed disk, SSD or HDD. If there are more than one failed disks in the system, please do not remove more than one SSD or HDD from the system at any point in time. Doing so could result in loss of data.

Note.png Note: Please ensure that a replacement SSD should always be placed in the slot that previously contained an SSD. Likewise a replacement HDD should be placed in a slot that previously contained an HDD.

Disk drives can be removed and replaced while the system is operational. To remove a disk drive, perform the following steps:

  • Identify the failed disk. In Web UI, navigate to Manage Hardware. Since the disk can fail in the head unit and/or in an EBOD enclosure (if using a 7520), look at the status of the disks under 'Shared Components' and under 'EBOD Enclosure'. A failed disk in an appliance unit will show up with red status. The figure below shows a 'failed' disk in Slot 5 of the appliance. All the disks in the EBOD enclosure in this case are 'healthy'.





  • Locate the disk drives in the front of the appliance or the EBOD enclosure. For the disk in question, the amber LED will be lit.




  • If the disk is unlocked, proceed to the next step. If the disk is locked, unlock the disk by following the procedure under 'Disengaging the Anti-Tamper Lock'.
  • For the failed disk, now keeping the black latch on the drive carrier module depressed, pull the drive carrier handle out away from the front of the chassis. 




  • Once the drive carrier handle is fully extended, slide the drive carrier out of the chassis.

Installing a Disk Drive

  • To insert a disk drive, ensure the drive carrier handle is fully extended.




  • With the handle extended, slide the drive carrier all the way into the chassis. 




  • With the drive carrier inserted, close the drive carrier handle while continuing to push the drive carrier into the chassis, until the drive carrier handle snaps into a locked position.




  • Verify the replacement was successful and the drive is operational by accessing Web UI and navigating to Manage Hardware. The disk replaced under 'Shared Components' and 'EBOD Enclosure Shared Components' should show up as green indicating it is 'healthy'.
