Veritas Volume Manager 5.0 Release Notes
Unsupported Features
Chapter 1 11
Disks that have been duplicated outside the VxVM environment (usually using
specialized hardware) are referred to as cloned disks. The vxdisk and vxdg commands
have been enhanced to allow such cloned disks to be identified, tagged, and more easily
managed. For example, a subset of the disks in a disk group that are similarly tagged can
be imported together in a single operation.
• ISP enhancements
The following enhancements have been made to the Intelligent Storage Provisioning (ISP)
feature:
—The vxassist command may be used instead of the vxvoladm command to create ISP
volumes as well as non-ISP volumes. Any vxassist specification attributes are
converted into equivalent ISP rules.
— The creation of a large number of volumes in a single operation, and retrieval of
information have been speeded up.
— Annotation of storage devices may now be performed by assigning tags and optional
tag values to disks and LUNs.
—The vxassist print rules or vxvoladm print rules commands may be used to display
the raw set of ISP rules that were used to allocate storage to a volume.
— A specified number of volumes with a given intent can be created at the same time.
— Additional information retrieval commands are provided to support queries such as:
— Given a template, return all template sets that refer to that template.
— Given a template, list all the templates on which the specified template is
dependent.
— The linked break-off snapshot volume feature allows ISP feature to support fast
resynchronization (FastResync) with snapshot operations such as refresh and restore.
— The ISP intent version number has been increased to 30.
— Migration between non-ISP and ISP volumes is supported.
