HP StorageWorks SAN Virtualization Services Platform Manager User Guide (5697-0454, May 2010)

DescriptionProperty
The state of the virtual disk. Possible values:
• Create—The active VSM server is creating the virtual disk. The VSM server
allocates the required capacity from the selected storage pools and updates
the setup database.
• Normal—The virtual disk is in a normal operational state.
• Delete—The virtual disk is being deleted. The VSM server marks the virtual disk
for deletion and waits for an acknowledgement from all the hosts that use it.
Once acknowledged, the VSM server deletes the virtual disk and marks the
capacity that it used as free space available for allocation. When the deletion
is complete, the virtual disk disappears from the Virtual Disk list.
• Migrate—A virtual disk is being created as part of Import-in-Place operation,
in which a native LUN becomes a VSM virtual disk and all data is preserved.
State
The storage capacity of the virtual disk.Capacity
Yes indicates that the virtual disk is defined as a cluster resource. This setting tunes
the SVSP system behavior when the virtual disk is permitted to multiple hosts
(configured as a resource in a cluster application). For a description of configuring
virtual disks for cluster applications, see “Defining virtual disks as
clustered” on page 119.
Clustered
Shows which hosts have permission to access the selected virtual disk. If a single
host has access permission for the virtual disk, the name of that host is displayed.
If multiple hosts have access permission, the word “multiple” appears.
Owned by Host
A free text display field. To modify the text that appears here, right-click the virtual
disk and select Manage > Edit Comment. You can use this field for any purpose.
Comment
The PiT granularity of the virtual disk. PiT granularity affects the capacity required
to store virtual disk updates after the creation of a snapshot PiT. The PiT granularity
is set to Large I/Os (1 MB) and is not configurable.
PiT granularity
If the virtual disk is a member of a virtual disk group, the name of the virtual disk
group.
VDG
The application associated with the virtual disk. For information about adding
application types and associating them with virtual disks, see “Adding applications
to virtual disks” on page 120.
Application Type
Yes indicates that this virtual disk is a thin provisioned virtual disk type.Is Thin Provision
This setting indicates whether the virtual disk is a SAN API virtual disk. SAN API
virtual disks are created to enable hosts to direct SAN API commands to VSM
through a DPM. For information about creating SAN API virtual disk, see “Creating
the setup virtual disk” on page 373.
SAN API Virtual Disk
The virtual disk's OpenVMS Unit ID (OUID). Possible values:
• 0—The virtual disk is considered as having no OUID assignment. This is the
default value.
• 1–32767
