WARNING: CBT: 2056: Unsupported ioctl 61

[sguk]

Hi there, we are getting these errors

2016-07-26T07:45:07.296Z cpu5:85313)WARNING: CBT: 2056: Unsupported ioctl 61

2016-07-26T07:45:07.296Z cpu5:85313)WARNING: CBT: 2056: Unsupported ioctl 60

They appear when backups are run

It seems to relate to

https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=20585...

VMWare say to ignore them, however, they state

• The only unsupported Input Output Control (ioctl) numbers reported are 58, 43, 59, and 60.

Our numbers are 44,60,61 so wondered if the “ignore the errors” still applies?

Appreciate any help.
