To work with ESXi, EMC Symmetrix storage systems require certain specific settings. Use EMC software to configure the storage system.

The following settings are required for ESXi operations on the Symmetrix networked storage system:

Common serial number (C)

Auto negotiation (EAN) enabled

SCSI 3 (SC3) set (enabled)

Unique world wide name (UWN)

SPC-2 (Decal) (SPC2) SPC-2 flag is required


The ESXi host considers any LUNs from a Symmetrix storage system that have a capacity of 50MB or less as management LUNs. These LUNs are also known as pseudo or gatekeeper LUNs. These LUNs appear in the EMC Symmetrix Management Interface and should not be used to hold data.
