Nimble Storage VSS backup error

[katbert]

I have Nimble Storage HF20H-2OBT-22T-1440F, with iSCSI connection to Windows Server 2012 R2 with NTW installed (Setup-HPEStorageToolkit-x64.7.1.1.68.exe). Firmware version is 5.2.1.800-930936-opt  - last version.

When my third-party backup software starts backup job, I get VSS error in Application windows log, and backup task fail.

Sourece: Nimble VSS Hardware Provider

Event ID: 4380

Unable able to read Group Management Credentials for array IP =10.0.0.2.Please reset the credentials using 'Set-NWTConfiguration'.

I try combination of Clear-NWTConfiguration and Set-NWTConfiguration, it accept my Nimble web interface credential, but backup jobs fail again and again.

I opened ticket 04781914 at supportcase@nimblestorage.com - but no useful answer for 15 days

Using procmon, I see - Nimble.VssProvider.exe try to read login and password from HKLM\SOFTWARE\Nimble Storage\Configuration\GrpMgmtProfileList\

[katbert]

Maybe update NWT 7.1.1.68 can help me?

NimblePowerShell.log - no errors in Clear-NWTConfiguration and Set-NWTConfiguration
