Limitations for SCVMM 2012
Review the following limitations before you use Microsoft SCVMM 2012 to discover the Dell SMI-S provider and Storage Centers.
Thin Provisioning
The SCVMM 2012 console limits the maximum volume size at creation time to the available capacity of the storage pool. Storage Center
thin provisioning does not have this restriction. This limitation can also cause the SCVMM 2012 console to display an error for "Allocated
Storage" if allocated storage exceeds the available physical storage.
To create a volume that is larger than the available storage pool, use the PowerShell cmdlet New-SCStorageLogicalUnit instead of
the SCVMM 2012 console.
Adding Server WWNs
If a WWN is not associated with a Storage Center server object, SMI-S creates one new server object for each available WWN. If a server
has more than one WWN, SMI-S creates one server object for each WWN instead of creating one server object with multiple WWNs.
If a server has more than one WWN, create the server object manually instead of allowing SMI-S to automatically create the object(s).
Volume Names
SCVMM 2012 does not allow spaces or special characters such as underscores or dashes in volume names. However, volumes that have
been created prior to discovery can include spaces in their names.
When creating LUNs using SCVMM 2012, do not include spaces in volume names.
Storage Center Controller Failover
In the event of a Storage Center controller failover, some operations may appear to fail in SCVMM due to timeouts. For instance, if
controller failover occurs when creating a volume in SCVMM, the volume is created successfully on the Storage Center but the operation
appears to fail in SCVMM.
In the event of a Storage Center controller failover, refresh the Dell SMI-S Provider in SCVMM. Refreshing the provider after failover helps
ensure that the information in SCVMM remains accurate.
Modify the SCVMM 2012 Management Server Registry to
Allow HTTPS
If you congured the Data Collector to use HTTPS for SMI-S connections, certicate errors can occur when SCVMM 2012 imports the Dell
SMI-S Provider certicate. To prevent these errors, edit the registry on the SCVMM 2012 management server.

CAUTION
: Serious problems might occur if you modify the registry incorrectly. For added protection, back up the registry before
you modify it.
