The IBM® Spectrum
Control Base Edition introduces a comprehensive storage virtualization
support, using VMware Virtual Volume (VVOL) technology.
Before you begin
- Verify that all required ESXi hosts are connected and defined
at the XIV® side.
- Verify that the Spectrum Control time is synchronized with the
time, used by the vCenter server.
About this task
This section details how to create a VVOL-enabled storage
service. The service or a group of services can be used to define
storage spaces, serving as virtual datastores for VM deployment.To create a VVOL-enabled storage service:
- Enable VVOL utilization at the XIV side.
- Create the service, using Spectrum Control.
Procedure
- Launch the XIV management
GUI and log in as a storage administrator.
- Create a domain with required soft and hard capacity. Make
sure that the soft capacity is four times larger than the hard capacity.
- Define a user with category storageintegrationadmin.
- Associate the storageintegrationadmin user
with the domain.
- Associate all ESXi hosts with the domain.
Important: The managed domain that
you created cannot be used for traditional volumes without virtualization.
You must create a separate regular domain for them. This domain must
have the same user and the ESXi hosts that you intend to manage. However,
you need to create a separate storage resource and a new service on
the regular domain via Spectrum Control for subsequent use by the
VMware vWC.

- Launch the XIV XCLI
tool.
- Enable the metadata service for the XIV, using the metadata_service_enable command.
- Close the he XIV XCLI
tool and return to the XIV management
GUI.
- Change the storage administrator user to storageintegrationadmin user and re-launch the XIV XCLI tool
- Create a new Administrative Logical Unit (ALU) per each
ESXi host. Use the following XCLI format: alu_create alu=<alu-name>
host=<host-name> lun=logical-unit-number. Make sure
that the LUN is in the 512–755 range.
- Launch Spectrum Control.
- Configure a fully qualified domain name for the Spectrum
Control server and define a high-availability group. See GUI – Defining a high-availability group.
- Generate a self-signed Spectrum Control server certificate.
See GUI – Managing server certificates.
- Set up VASA credentials. See GUI – Setting the VASA credentials.
- Enable the storageintegrationadmin to access
the XIV storage resources. See GUI – Entering the storage array credentials.
- Add the XIV array
to the Spectrum Control. See GUI – Adding a storage array.
- Add a new storage space. See GUI – Adding a storage space.
- Add a VVOL-enabled service to the storage space. See GUI – Adding a storage service.
- Define a storage resource and attach it to the VVOL-enabled
service. See GUI – Defining and attaching storage resources.
- Register Spectrum Control as a storage provider on VMware
vCenter server. See Registering Spectrum Control as a storage provider in vCenter server.
- Launch the vWC and create a VVOL-enabled datastore. Select
the storage space that you defined as an underlying storage resource
for the datastore.
