Timeout when running "Rescan datacenter HBAs"

Hi there!

When I run the workflow "Rescan datacenter HBAs" I get the following error message after the first ESXi Host (I replaced our hostname) is scanned:

[2015-11-11 10:51:33.300] [I] Rescanning HBAs on : HOSTNAME

[2015-11-11 10:51:33.325] [I] rescanning HBAs on host 'HOSTNAME'... please wait...

[2015-11-11 10:53:02.019] [E] Error when rescanning VMFS. Reason: InternalError: ; nested exception is:

   java.net.SocketTimeoutException: Read timed out (Dynamic Script Module name : rescanHostHBAs#4)

[2015-11-11 10:53:02.044] [I] Error when rescanning VMFS. Reason: InternalError: ; nested exception is:

   java.net.SocketTimeoutException: Read timed out (Dynamic Script Module name : rescanHostHBAs#4) (Dynamic Script Module name : rescanHostHBAs#9)

But the rescan HBAs and VMFS of this host runs just fine within the vCenter. OK it takes some time because we have a lot of Datastores but there is no error.

Is there a way to increase the timeout value or do I have to modify the workflow somehow?

Sorry for my bad english ;-)
