HI,
We have in our infrastructure :
- Production Luns on a PureStorage Bay , on each Lun the SIOC option is deactivated.
- 3 luns from another bay with the SIOC option enabled
Nevertheless, for several days, we have warning messages concerning our PureSTorage luns
An unmanaged I/O workload is detected on a SIOC-enabled datastore: XXXXX-PUR-XX-XXXX" |
Do you know why ?
Yes, you will be able to disable the alarm related to these events. But makes sure there is no misconfiguration. Run through the article and make sure of same.
Though alarm can be disabled, I'm not sure if there is any way to prevent message from appearing in logs. Let other folks suggest for any way around here.
Do you have the LUNs presented to ESXi hosts to any other device or servers like backup etc.? This message is seen when LUN is presented to servers other than ESXi where I/O observed from outside host.
Refer VMware Knowledge Base
Yes, we have a NETBACKUP solution.
So do not consider all these alerts. Is there a way to disable them?

Thank you, because I had read this article, but I was sure to understand.
Scenario 2
The array being used for vSphere is also being used for non-vSphere workloads. The non-vSphere workloads are accessing a storage volume that is on the same disk spindles as the affected datastore.
Read through the below article to understand more towards what you have pointed out.
