My storage admin just told me that they are seeing possible corruption (maybe false positive) on a m disk in a v7000 SAN.
As they cant see inside a LUN they have presented to my hosts the SAN admin is suggesting I should run a chkdsk equivalent on my LUN/Datastore.
I have never come across this before and a bunch of googling didn't make me any smarter in this matter.
Now, I am not seeing any corruption of my VM's running on that datastore and obviously they would not see anything as they are abstracted from the storage.
Would this be a chkdsk from the console of the ESXi host? or perhaps something I can do via powercli. Any kind of service interruptions to expect or perhaps i should vacate the LUN/Datastore.
I spoke with my SAN admin and he mentioned he have seen false positives of corruption before on this array.

You can use VOMA utility on esxi hosts to check luns or vmfs datastore metadata checks VMFS file system metadata check. Here is VMware KB VMware Knowledge Base
Note: when you perform checks make sure you move all vms to another datastore or power off the vms and then perform the check against datatstore.
