Mac clients flooding Quantum MDCs with requests on startup.

We have an assortment of Mac clients that connect to Quantum MDCs (M440/5) for the volumes. When these Macs (running Mavericks) startup , they flood the MDCs with request for their LUNS. Something in the startup of the OS isn't showing the fiber LUNs at that time, so the client asks the MDCs again, and again, and so on. When the LUNs finally do show up on the fiber ports, Xsan connects to the volumes just fine.

Is there a way to delay Xsan startup until the fiber ports have been initialized properly?

We are using ATTO CelerityFC8 fiber cards, and zoned via Brocade DCX switches.

Thanks

Are you ports set init/target? Is this causing issues with the storage? Crashing etc? What did quantum say?
