Replistor causing VSS service to stop and start

Question

Has anyone seen this issue before - it's only started since upgrading to 6.1. It on a windows 2003 SP1 server with KB891957. Within the specification window I have 'unticked' VSS enabled. We do not use VSS at all so would liek to disable the service but Replistor is trying to use it for something? Any ideas/pointers?

VSS is Volume Shadow Service which enables you to protect system files; can you explain the symptoms you are seeing here. What is Replistor doing at time of starting the service and of stopping the service?

Replistor is running as normal all day and the VSS service is still stopping and starting thats the issue I haven't got a clue why. 6.1 must be doing with VSS as described in the admin guide. How do you disable this
In general, the RepliStor/VSS sequence of events that occurs in the
creation of a shadow copy on the target is the following:
1. On the source side, the RepliStor Requestor (initiated via the
RepliStor GUI) requests a VSS shadow copy.
2. VSS then asks the Exchange VSS Writer to freeze and flush all its
I/O.
3. When this is completed, VSS asks the System Provider to take a
shadow copy.
4. The RepliStor kernel interfaces with the VSS System Provider to
determine when the I/O is that of a VSS shadow copy. This is the
consistent data that is denoted by a marker which is passed to the
target RepliStor server.
5. When the kernel marker is received at the target side, this
indicates that the replicated data on the target is at the same state
as the source at the time the data was frozen. This data is the
consistent data for Exchange.
6. The target RepliStor server then optionally uses the RepliStor VSS
Requestor to initiate a shadow copy on the target.
7. Once the shadow copy is on the target, the shadow copy can be
mounted (if configured) and a user-supplied script can be run (if
configured).

After raising this call with EMC Support - It appears this is a bug fixed in 6.1.1 (due for release soon)bug is LGTpa80520

yito1 · Answer

RpliStor6.1.1 of warning of the VSS service is not solved in LGTpa85020 either.

In my environment, RepliStor6.1.1 is installed.

However, VSS waring ID:12290 is output.

It is thought that this is a bug.

6.1.1 lists LGTpa85020 (The event log fills rapidly with VSS messages) as addressed. If you have the same issue peraps it is a different than original one so you will probably need to fill new escalation with support.

dramjass · Answer

This issue has actually been resolved and will be in the next release verion of RepliStor. The LGTpa85020 you mentioned is different from the one described here.

Keep an out out for the software as RepliStor does not have patches to release.
