Working with Clusters
Clustering is the connecting of two or more computers together in such a way that
they behave like a single computer. Clustering is used for parallel processing, load
balancing, and fault tolerance.
The supported clustering software for Windows is Microsoft Cluster Server
(MSCS). See the platform-specific release notes for the specific version of the
supported clustering software.
Be sure to install the Windows Kit on each server in the cluster. Refer to the
documentation that came with the clustering software for more specific
information.
Expanding Volumes
You can increase the volume size of the virtual disk with the Command View
EVA. You simply change the size parameter in the particular virtual disk’s
property page. However, only Windows 2000 supports volume expansion.
Note: After a virtual disk is created, you can only increase the size, not decrease it.
Windows NT does not support dynamically growing a virtual disk volume. If you
need to increase the size of a virtual disk, use the workaround that follows (see
“Volume Expansion Workaround” on page 32).
Note: As with any large-scale operation, it is always best to first create a backup of
your data.
The disk management utility DiskPart is necessary to expand volumes on
Windows 2000. DiskPart is included in the Microsoft Windows 2000 Resource
Kit or from the Microsoft website. If this utility is not installed, install it before
attempting to expand virtual disks on the Enterprise Virtual Array.
Only Basic Disk volumes formatted with NTFS can be expanded with the
procedure described here. You do not need to stop applications while expanding
the volume.
1. Increase the virtual disk size using the Command View EVA.
