Getting false positives on Veeam ONE from vCenter on Nimble datastores/LUNs/Devices that do no l

[UCL]

Hello.

Veeam One which is a reporting tools sees esx.problem.storage.connectivity.lost events from vcenter. This happens accross all eight ESXi 6.7 U3 hosts in vcenter connected to two Nimble HF40 boxes. VMware found a folder on each host containing a sort of SCSI databasefile with all the non-existing datastores/LUNs/Device in it. Clearing those files and rebooting the Host did not solve the problem as it returned within 12 hours. The files got repolulated. Then VMware found SCSI related files from Nimble. We use FC for datastore connection. These files are:

May we delete these files or what are their function?

Hello,

Please open a Nimble support case to investigate properly.

Do not delete these files.  They are files/scripts used by the Nimble Connection Manager.  For more details/information, please read the VMware Integration Guide you can find on InfoSight.

As Nick mentioned, to investigate the esx.problem.storage.connectivity.lost events, please reach out to Nimble Support.
