4. Use SCVMM 2012 to Discover the Dell SMI-S Provider
Verify SCVMM 2012 Prerequisites
Verify that the following requirements are met before you to use Microsoft SCVMM 2012 to discover the Dell SMI-S provider and
Storage Centers.
• Microsoft SCVMM 2012 server and the Storage Manager Data Collector must be installed on separate servers, and both servers
must be members of the same Active Directory domain.
• SMI-S must be enabled and congured for the Storage Manager Data Collector.
• The Storage Centers you want to manage with SMI-S must be added to the Storage Manager and mapped to the SMI-S user.
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.
