False Drive Offline status on some Q-series models

Description 

Some drives may show an “offline” status on the hardware tab in ExacqVision Client when Server Version 23.03.1.0 is installed on Q-series models, though data can be read from and written to the drive.

Note: This issue manifests itself cosmetically by appearing as if the drive is offline but has no bearing on functionality for video searching.

Product 

ExacqVision Server Version 23.03.1.0

Steps to Reproduce 

Update to Server Version 23.03.1.0 from a previous server software version.

Expected Results

Drives should populate hardware tab with a healthy status.

Actual Results 

One or more drives may appear as “Offline” on the hardware tab.

Solution

Update to ExacqVision Server 23.03.2.0 if SSA is current and up to date, or alternatively rollback to ExacqVision Server 20.12.8.0 as a workaround.

How to Determine if a Drive is Read-Only

In Linux systems a filesystem error may cause a storage volume to be re-mounted by the operating system as Read-Only. This could be evident on the Storage page under the Drives tab when the volume status changes to ‘Write Error’ or when you attempt to search for video and find the system does not appear to be recording recent video.

<br>

How can you determine if the volume is now Read-Only?

Make a note of the volume you suspect as being Read-Only. Open a Terminal window and change directory to that volume. If the storage label is /mnt/edvr/1, enter:

cd /mnt/edvr/1

Attempt to make a new file in this location by entering:

sudo touch test.txt

If the command prompt returns without any other message, the file was created successfully and this volume is not currently in a Read-Only state.

If you get a return message that the file was unable to be created because it is Read-Only you may want to run fsck on the volume to try to correct any filesystem errors and remount it.

ExacqVision A-Series 4U Drive Replacement Guide

NOTE: This article assumes that you already know which drive number must be replaced, and that you have a replacement drive ready to install in the system.

NOTE: The photos in this article illustrate the replacement of Drive 3.

To replace a hard drive in an exacqVision A-Series 4U system manufactured on or after 07/30/2015, complete the following steps:

  1. Shut down the system and remove all power cables.
  2. Use a screwdriver to remove the screws that hold the system lid in place. Remove the lid.
  3. Locate the drive that needs to be replaced. Drives are labeled by numbers 0 up to 7 (the Drive 3 label is circled in the blue oval in the following image).

    Power and communication cables must be removed from all drives in the same cage — drives 0-3 or drives 4-7. Power cables are on top (circled in red) and communication cables are on the bottom (one example is shown in a green oval). Note the labels on the communication cables, as they must be plugged in later in the same order.
  1. Remove the screws that hold the cage in place. There are two screws on the side of the chassis and four screws on the bottom. For better access to the screws on the bottom, you can tilt the system on its side as shown. CAUTION: If you tilt the system on its side, hold the cage in with your hand as you remove the screws so that the cage does not fall out of the system.

<br>

  1. Slide the cage up and out of the chassis.
  1. Remove the screws that hold the drive in its cage. There are two screws on the bottom of the cage and two screws on top of the cage. Remove the drive from the cage.

<br>

  1. Slide the replacement drive into the empty slot in the cage. Secure it in the slot using the four screws removed in the previous step.
  2. Slide the cage back into the chassis and affix it with the six screws removed in step 4.
  3. Plug the communication cables into the drives. Note the labels on the cables and plug them in order according to the drive numbers.
  4. Plug the power cables (in any order) into the drives.
  5. Secure the system lid using the screws removed in step 2.
  6. Connect the power cable and start the system.
