Windows 2016 VMware slow performance. Disks listed as unspecified
Hi Everyone, I am having performance issue with Node 1 in a two nodes database cluster. They both has identical VM hardware settings and sitting on the same datastore. However, I noticed differences on Node1 compare to Node2 is that all VM disks on listed as unspecified devices under Devices and Printers While Node 2 seems to be fine as expected. Also, on Node 1, there are some volume shadow copies (does not exist on Node2) that has error 45 as below My concerns are: What could cause Windows listed all disks as unspecified on Node 1. Have already reinstalled latest VM Tools Volume shadow is disabled on disks, what are those shadow copies in the list? Do they cause disks become unspecified. Is the slow performance (read/write to any disks, login, Windows update ) on Node 1 because of the unspecified disks? Any ideas to solve the problem is very much appreciated. Regards, Ken.
