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.
