Clusters > cluster_name > Storage

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 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.
