EMC Symmetrix storage systems work with ESXi hosts in FC SAN configurations. Generally, you use the EMC software to perform configurations.
The following settings are required on the Symmetrix networked storage system. For more information, see the EMC documentation.
Common serial number (C)
Auto negotiation (EAN) enabled
Fibrepath enabled on this port (VCM)
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 array with 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.
