Creating Pools
and Virtual
Disks
StorageWorks NAS utilizes a software program named SANworks Virtual Replicator to
virtualize storage at the host based level. Once LUNS have been presented to the nodes
it is possible to create Pools of storage. Pools can be comprised of up to eight LUNS.
From the Pools Virtual Disks can be created. Up to eight virtual Disks can be created
from a single pool. In a cluster configuration, when a Pool is created it will show up as a
SCE Pool resource in Cluster Administrator. Additional information about SWVR can be
located in the Administration Guide for the respective product.
Creating a SWVR Pool through the WEBUI
Note: Ensure that a local administrator’s account is logged in locally ON BOTH NODES
before creating any SWVR resources remotely. The server console may be locked after
the local administrator’s account has logged in. This can not be accomplished through
terminal services; it must be done locally at the console or through the RIB board.
• Open the WEBUI and select the Virtual Replicator link from the menu on the left
hand side
• Select Pools
• Select New
• Select the storage unit or units that will compose the pool, name the pool and
specify the segment size and select OK.
Creating a SWVR Virtual Disk through the WEBUI
Note: Ensure that a local administrator’s account is logged in locally ON BOTH NODES
before creating any SWVR resources remotely. The server console may be locked after
the local administrator’s account has logged in. This can not be accomplished through
terminal services; it must be done locally at the console or through the RIB board.
• Open the WEBUI and select the Virtual Replicator link from the menu on the left
hand side
• Select Virtual Disk
• Select NEW, then select NEXT
• In the drop down list select the Pool the virtual disk is going to be created from
and select NEXT
• Name the Virtual Disk and specify the capacity. The capacity available is the
figure listed under free space – 30%. The 30% is the snapshot reserve. Select
the driver letter and specify if it is to be formatted. Select Next
• Confirm that all of the settings are correct and select Finish.
Creating Cluster
Virtual Servers
and Cluster
aware file share
resources.
Once the cluster installation is complete it is possible to create Virtual Servers and Cluster
aware file share resources.
Virtual Servers
Through server clusters, StorageWorks NAS enables the creation of virtual servers.
Unlike a physical server, a virtual server is not associated with a specific computer and
can be failed over like a group. If the node hosting the virtual server fails, clients can still
access its resources using the same server name. A virtual server is a group that
contains:
• A Network Name resource.
• An IP Address resource.
• The physical disks and file shares to be accessed by the clients of the virtual
server.
A virtual server acts like a physical server in the following ways:
