Issues Specific to EMC Symmetrix Storage Systems
The following issues are specific to EMC Symmetrix Storage Systems:

• ”LUN Provisioning Is Not Supported with Solutions Enabler 4.3” on page 388
• ”“Process Has an Exclusive Lock” Message” on page 388

About Provisioning on EMC Symmetrix Storage Systems
EMC ships its Symmetrix storage system with volumes already created. When the software first
discovers an EMC Symmetrix storage system, it assumes the devices on the Symmetrix storage
system are volumes.
This software refers to the term “device” to define a piece of hardware in the storage network. EMC
uses the term “device” to refer to a volume on one of its storage systems. In this section, the term
“device” is used in the context of EMC storage systems.
When you use the software's “create a volume” feature, you are assigning the already created
volume. If necessary the software will create a meta device, which is a device that is a
concatenation of several devices.
The software does not delete the volumes created by EMC. When you use the software's “delete a
volume” feature, the software marks the volume as hidden in its repository. These “hidden volumes”
are stored in the “Free Device” list.
If you use a device in the “Free Device” list when you create a volume, that device is removed from
the “Free Device” list. The device was moved from the list because it is now assigned.
LUN Provisioning Is Not Supported with Solutions Enabler 4.3
LUN mapping and LUN Masking works only when SYMAPI server version 5.0 or later is used.
SYMAPI version 4.3 does not allow LUN provisioning, even though it shows existing LUNs. It also
does not show existing LUN maskings.
