If you need virtual machines to access the same raw LUN, they must share the same RDM mapping file. For more information on this type of configuration, see:
The config.vpxd.filter.rdmFilter
and config.vpxd.filter.vmfsFilter
configuration options in the vSphere Client control the LUN filtering mechanism. The options are set to true
by default, but can be individually set to false
when you need to turn off any of the filters.
However, you should not turn the filters off unless you have other methods to prevent LUN corruption.
Note: If you are upgrading your environment, check the values after the upgrade as the values can return to their default setting.
To turn off any of the filters using the vSphere Client:
- In the vSphere Client, click Administration > vCenter Server Settings > Advanced Settings.
- Depending on your needs, add one or both of these key and value pairs:
config.vpxd.filter.rdmFilter
; false
config.vpxd.filter.vmfsFilter
; false
- Click Add, then click OK.
- Highlight the affected ESXi host cluster and click on Rescan for Datastores.
To turn off any of the filters using the vSphere Web Client, see the
Turn off Storage Filters in the vSphere Web Client section in the
vSphere 5.5 Storage guide.
Now, if you create a virtual machine with RDMs, all shared LUNs are displayed as RDM candidates even though they are already being used on a different ESXi/ESX host.
To turn on the filters again, set the values to
true
.
