Use this page to view and edit volume groups or disks.
The Storage page provides a View field
where you can select either the Volume groups option
or the Disks option. After you select one of
these options, you can view and edit the properties for volume groups,
logical volumes, file systems from the Volume Groups page.
From the Disks page, you can view and edit
the properties for disks.
Most of the PowerHA® configurations
require shared storage. Shared storage configurations support access
from multiple nodes. Storage resources consist of volume groups. Volume
groups are containers for logical volumes, file systems, and shared
disks.
Disks reside in a volume group and are associated with a file system.
File systems reside entirely in a logical volume. Logical volumes
reside entirely in a volume group.
Note: IBM® Systems Director
provides some tasks that start outside of the IBM Systems Director Web interface. These tasks
are launched tasks. They are identified on menus by the
Launched
tasks icon

. For more information on resolving launched task
issues, see
Launched tasks troubleshooting in the IBM Systems Director V6.2.x information
center.
Volume group tasks
- Create a Volume Group
- Use this task to create a volume group by specifying a set of
cluster nodes and disks.
- Create a Volume Group with Data Path Devices
- Use this task to create a volume group by specifying a set of
cluster nodes and data path devices disks.
- Add a Logical Volume
- Use this task to add a logical volume to a volume group.
- Import a Volume Group
- Use this task to import a volume group on all nodes belonging
to a resource group.
- Mirror a Volume Group
- Use this task to mirror all logical volumes in a volume group.
- Un-mirror a Volume Group
- Use this task to un-mirror all logical volumes in a volume group.
- Enable/Disable Concurrent Access
- Use this task to convert an existing non-concurrent volume group
to an enhanced concurrent mode to take advantage of fast disk takeover.
- Synchronize a Volume Group Definition
- Use this task to verify that the LVM definition of a volume group
is the same on all cluster nodes before a failover occurs.
- Synchronize Mirrors
- Use this task to synchronize all logical volume mirrors in a volume
group.
- Properties
- Use this task to view the properties of a volume group.
Logical volume tasks
- Add a File System
- Use this task to add a file system to a logical volume.
- Add a Disk
- Use this task to add a disk to a specified cluster node or nodes.
- Increase Size
- Use this task to increase the size of a logical volume by adding
unallocated physical partitions from within the volume group.
- Synchronize Mirrors
- Use this task to synchronize all logical volume mirrors in a volume
group.
- Add a Copy
- Use this task to increase the number of physical partitions per
logical partition within a logical volume.
- Remove a Copy
- Use this task to de-allocate copies from each logical partition
in a logical volume.
- Rename
- Use this task to rename the logical volume.
- Remove
- Use this task to remove a logical volume from a volume group.
If the logical volume contains a file system, it must be unmounted.
- Properties
- Use this task to view the properties of a logical volume.
File system tasks
- Remove
- Use this task to remove a file system from a logical volume.
- Properties
- Use this task to view the properties of a file system.
Disk tasks
- Add Paths
- Use this task to dynamically add paths to virtual path (VPATH)
devices belonging to active volume groups.
- Configure as Data Path Device
- Use this task to define and configure a disk as a data path device
used by the operating system for selected nodes in the cluster.
- Convert to VPATH
- Use this task to convert a volume group from hard disk (HDISK)
to VPATH by specifying a set of cluster nodes and a volume group.
- Convert to HDISK
- Use this task to convert a volume group from VPATH to HDISK by
specifying a set of cluster nodes and a volume group. Use this task
when you want to configure your applications back to original HDISK,
or when you want to remove the VPATH from your host system.
- Replace
- Use this task to replace a failed cluster disk in a volume group.
You must be the root user to perform this task.
- Remove
- Use this task to remove a disk (HDISK or VPATH) from a specified
cluster node or nodes. The disk can also be made unavailable, but
still defined.
- Properties
- Use this task to view the properties of a disk.
