ESX servers rescan HBAs when adding new Datastore
Got this tip from Duncan from Yellow Bricks. If you make any changes to a datastore add/delete/extend all the ESX servers will automatically do a HBA/VMFS rescan. You can imagine that it is pointless to rescan your HBA 25 times in a row when you are adding more than 1 new datastore. Open up the vSphere Client
1. Go to Administration -> vCenter Server
2. Go to Settings -> Advanced Settings
3. If the key “config.vpxd.filter.hostRescanFilter” is not available add it and set it to false
Make sure to set it to “true” as soon as you are done!!!!
To change it back to true you will have to edit the vpxd.cfg file unless VMware fixed the bug to change the Value to true.
C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter
<hostRescanFilter>true</hostRescanFilter>
