Issue with MSA2000 VSS provider

[Fabio_S]

Hello,
I have 5 BL460 G1 connected to an MSA2000 SAN (FC). They are all running WS2K3 R2 SP2 x64, and I installed the MSA2000 SES Driver (2.3) on all of them.
It seems only one of them has now the HP MSA2000 VSS provider installed, which causes issues with Symantec BackupExec. Other ones have only Microsoft VSS provider and I can backup them normally.
Is there a way to deactivate-remove the HP VSS Provider? Without of course impacting the connection to the SAN (it's a production server...)
thanks!

Hello,
since the VSS provider was listed by the "VSS list providers" command but was not in the Windows Add/Remove Programs, I could not remove it.
So I installed the new version (2.4), removed it form ARP (now, it was there), and finally tried again to backup with BackupExec.
This time everything was fine.
