Symptoms

Possible issues: RecoverPoint Appliances may not be able to see/add the Unity (splitter*)Latency and unstable flow between RecoverPoint and the UnityUnity SPlogs streaming with the following error: "12b000f [INFO] System: SANCopy Disk Driver: Search failed : could not find or access FC Port xxxxxxxLUN xx : status = 7E11F013" Error code 0x7e11f013 is EMCPAL_STATUS_NO_SUCH_DEVICE What is the RecoverPoint Splitter? A RecoverPoint component that resides on the Unity array.It is in charge of splitting write I/Os (sending one copy to the Unity and one copy to the RecoverPoint Appliances) and keeping consistency for the replication copies.

Cause

From the Dell EMC Unity: Replication Technologies White Paper in the RecoverPoint with Dell EMC Unity section (page 74): "RecoverPoint should not be configured to use the Dell Unity Synchronous Replication Port on either storage processor." In the same document, the Synchronous Replication Interfaces section explains which port is reserved for Native synchronous replication:"Native synchronous block replication is performed over the first Fibre Channel (FC) port configured on the system."For Virtual RecoverPoint (vRPA), the same concept applies to the first Eth/iSCSI ports on each Storage Processor (SP) on the Unity array. Since these are part of the SP and cannot be changed, they are always the first Eth ports on each SP (SPA/B Ethernet Port 2).

Resolution

The array ports must be reorganized so that this conflict is removed. Disregarding this may result in unexpected behavior.Zone RecoverPoint to ports other than the Array Native Replication ports.
