Checking VMFS for errors might arise when you are unable to modify or erase file on a VMFS datastore or problems accessing specific files.
Typically using VOMA should be done when one of the following occurs:
SAN outage
Rebuilt RAID
Disk replacement
** Important ** Before running voma ENSURE that all VM's are turned off on the datastore or ideally migrated onto a completely different datastore.
You should also ensure that the datastore is unmounted on ** ALL ** ESXI hosts (you can do this through vSphere)!
SSH into the ESXI host and run the following:
voma -m vmfs -d /vmfs/devices/disks/naa.00000000000000000000000000:1 -s /tmp/analysis.txt
(Replacing 'naa.00000000000000000000000000:1' with the LUN NAA ID and partition to be checked.)
