Symptoms

After newly installing or upgrading to Oracle VM 3.4.2, the length of time to perform storage refresh or physical LUN refresh of a Fibre-Channel (FC)/SCSI connected storage array increases considerably.
The more LUNs/paths/devices and Oracle VM Servers in use, the longer the time it takes for storage/physical LUN refresh to complete.

For example, when previously running Oracle VM 3.4.1, storage refresh of an array with a large number of LUNs took ~50 seconds.
However, after upgrading the server to Oracle VM 3.4.2, storage refresh of the same storage array now took more than 1 hour and 40 minutes to complete.

This issue affects new installations of, as well as upgrades to Oracle VM version 3.4.2.
Note that this issue does not affect iSCSI-based storage arrays.

Changes

Oracle VM, specifically, Oracle VM Server, is newly installed with or upgraded to version 3.4.2.
