i have a Iscsi Datastore with just some templates that is not used frequently and l prefer the disks to stay parked/spinned down. Problem is every 30 minutes venter refreshes the Datastore waking up the disks and causes it to spin back up. looking at the vpxa logs on the esxi host I can see this datastore is automatically refreshed every 30 minutes Updating time stamp and free space values. is there a vcenter variable I can add to the vcenter server settrings that controls this 30 minute refresh interval? i tried changing the value of the hostd config.xml refeeshinterval to zero to disable it but it appears to only control automatic refreshing from the esxi host. Vcenter vpxa still scan every 30 minutes. How can I change or filter this datastore from getting rescanned so often?
I have never heard of such an option because you have a very specific use case which isn't really seen in live production environments, just home labs. The only thing I can recommend is (if you have it) open an SR and see if engineering has any under-the-hood switches which control this behavior.
I think that vcenter parameter only applies to rescanning of hbas and not datastore refreshing? Am I wrong could the filter stop Datastore refreshes from vcenter every 30 minutes?
i did try setting the datastorerefresh interval to 60 in the config.xml file on the esx host but vcenter still does a refresh of the Datastore every 30 minutes and this caused the local host to do an additional refresh every 60 minutes . It looks like by default hostd local host auto refreshing is disabled so took out the 60 minute refresh parameter.
