The RAID card configuration has been lost and the first drive inserted into the array is >750GB. We must utilize a 1TB harddrive at 750GB capacity.

Product Line

Pelco Video Management


  • Endura NVR5100
  • Endura DVR5300
  • Endura SEB5100


  • The latest firmware installed on the LSI cards used in the NVR5100, DVR5300 and SEB5100 series does NOT support 1TB harddrives.
  • The 750GB hard drive has been obsolete from our inventory. It is very difficult to find a manufacture that still produces this drive size in the required quantity. 
  • Pelco will NOT be releasing new firmware for the LSI RAID card that supports 1TB drive capacity.


note: ALL of these methods will result in 750GB capacity being utilized of the 1TB hard disk drive. 

Use only 1 of the following methods, as desired for the specific scenario...

Method 1: If a single drive has failed in an array and needs to be replaced with a 1TB drive:

1. Replace the defective 750GB drive with a 1TB drive.

2. Allow it to fully rebuild.

3. After rebuild is completed any other drive failures may be replaced in the same manner.

Method 2: Recommended method if more than 1 drive must be replaced at the same time within either of the two 6 drive sets (drives 1-6 or 7-12):

!! WARNING: This method results in loss of video data from drives 1-6, 7-12, or both !!

Use the NVR-DVR_large_drive_support.exe. The instructions below are included with the utility when it starts. These are not necessarily required but they are the steps that will most likely produce the desired result in a verity of scenarios. 

1. Power off the recorder.

2. Remove ALL storage drives. (You can slide the tray half way out)

3. Power on the recorder. It will begin to alarm, this is okay.

4. Wait for the recorder to respond to a ping.

5. Insert the storage drives for the array that you plan to configure.

6. Continue with the on screen prompts.

7. The system will halt after the restore completes.

8. Power on the recorder.

Method 3: Use instead of Method 2 if no internet access is available to obtain the required "NVR-DVR_large_drive_support.exe" file:

!! WARNING: This method results in complete system wipe, meaning all video and network configurations are lost !!

1. Insert a 750GB drive into slot 0 of the array.

2. Insert 1TB drives into slots 1-5 of the array.

3. Run the ship_prep script.

      Note:This will wipe the array of video and should only be used as a last resort


4. After rebooting the unit, confirm that the volumes are mounted and functioning properly with df and nsdterm at the command line (use "o" once in nsdterm).




5. Remove the 750GB from slot 0.

6. Insert a 1TB drive into slot 0 an allow it to fully rebuild.

Method 4: Use this method for SEB5100 units, or if you only need to do one of the two drive-sets (1-6 or 7-12 but not both), and don't want to lose network configurations

!! WARNING: This method results in loss of video data from drives 1-6, 7-12, or both !!

This method is the manual process of what the NVR-DVR_large_drive_support.exe performs.

1. Right click the recorder device in Endura Utilities and select SCP.

2. Select Copy files to.

3. Copy the 750Array_cfg to the recorder device. Example remote path: /root

4. Run the following commands. Replace "X" with the desired controller card (i.e. a0 or a1)

/etc/init.d/hald stop

/etc/init.d/nsdd stop

/etc/init.d/acpid stop
