Storeoncesoftware store(gateway) failed to start

Error: When you try to start the store in HP Data protect storeoncesoftware (Depdupe) it fails and gets an error message “ Failed to start the store” and when you execute the command

C:\> storeoncesoftware –list_store the store status will be in stopped state.”

Root cause: This problem occurs due to bad integrity in the backup file and we need to remove those files.


The following are the solution to remove the bad integrity files and the diag files in task_hk folder.

To identify this file we need to run the gokhans collector tool, the url link is given below.

To run this js file the steps are given below.

a. Open an MS-DOS prompt
b. Run the script using the following syntax:
c.  c:\> cscript //B //Nologo sosdc_win.js >sosdc.html

After getting the html result you can identify the filepath of bad integrity file and do the procedure given below.

1.Stop all stores using command “StoreOnceSoftware –stop_store –name=StoreName”

2.Stop StoreOnceSoftware service

3. Remove s.bad_integrity file

4. Delete all the files and directories under the folder $StoreRoot/StoreOncelibrary/dvol_000000x/committed/storemgr/store.d/store_x/ (you will see one xml file)

(x is 01, if the store is the first store; 02 for the second store; and so on)

5. Start StoreOnceSoftware service with debug

On Windows using command “sc start StoreOnceSoftware –log_level=tracing”

On Linux using command “/opt/omni/lbin/StoreOnceSoftware –daemon –log_level=tracing”

6. Check if the store can be started or not using command “StoreOnceSoftware –list_stores”, check the status of the store.

“[10054] Connection reset by peer” – HP Dataprotector B2D

In HP dataprotect the B2D backup fails with the error message “[10054] Connection reset by peer.”

This failure cause can be due to high network or computer usage, unreliable network or connection between different OS.


You can configure the TCP/IP protocol to use 8 instead of the default 5 retransmissions. It is better not to use higher values because each increment doubles the timeout. The setting applies to all network connections, not only to connections used by Data Protector.

On Windows, apply the change to the Cell Manager first.

1. Add a new DWORD parameter TcpMaxDataRetransmissions and set its value to 0x00000008(8) under the following registry key:


Making a mistake in editing the registry can cause your system to become unstable and unusable.

2. Restart the system after making this change.
