Online Volume Growth - Compaq N2400 - TaskSmart - 1 GB RAM Administration Manual

Online Volume Growth

The SWVR online volume growth feature directs the operating system to
update the size of a physical drive or virtual disk without requiring a system
restart. Online volume growth can also instruct the operating system to grow
the on-disk partition information for a volume. This feature allows a volume to
grow into unused space made available by either increasing the size of a drive
or by deleting one or more adjacent partitions. With online volume growth,
you can increase storage capacity, as required by your users and applications,
easily and with zero downtime.
Preparing for Online Volume Growth of Basic or
Virtual Disks
Before growing a volume, review the following checklist:
Make a reliable backup copy of the data. If the drive that you plan to
grow contains any data that you want to keep, it is recommended that
you back up the data.
Plan for new storage. Adding capacity can increase the time required to
create backups.
Before performing online volume growth, make sure that the pools that
you have created have adequate free space. When you increase the size
of a virtual disk, it consumes more space in the pool and reduces the
amount of free space that can be used for snapshots of virtual disks.
When replacing hard drives or using the ACU to perform array
expansion, the controller must finish rebuilding/expanding/extending
before online volume growth can be performed.
Using the ACU to modify an array takes time. Examine the current
controller rebuild/expand priority settings. See the documentation for
the Compaq Array Configuration Utility.
