After I placed two new 146 GB SAS hard disks to an ESXi 4.1 host, configured a new array, try to add a new datastore with my vSphere Client I received this warning:

Call “HostDatastoreSystem.QueryVmfsDatastoreCreateOptions” for object “ha-datastoresystem” on ESXi “SERVERNAME” failed.

After reading VMwareKB 1008886 and following the instructions I solved the issue..

Solution:

Commandline:

dd if=/dev/zero of="/vmfs/devices/disks/vml.0000000000766d686261313a313a30" bs=512 count=34 conv=notrunc

Output:

34+0 records in
34+0 records out
