LUN Utilization Summary for EMC VPLEX Arrays

Detail reports are related to a specific enterprise object, such as a backup job. You can only access detail reports through a link presented in the context of a main report, providing additional information that augments the main report. Detail reports cannot be generated, customized, or saved, as they are specific to the report from which they were derived. They are not available in search results.

Explore your data center using IT Analytics customizable report templates or by using parts of your IT infrastructure as entry points. Use Search to find reports, templates and dashboards across the portal.

Use the Reports tab to examine the IT Analytics catalog of templates, dashboards and reports - organized by products along with user-created, and system folders. The main report is located here:

Table: LUN Utilization Summary for EMC VPLEX Arrays

Column name

Description

Cluster

Name of the storage array.

Virtual Volume

Name of the virtual volume.

Mirror Cluster

Name of the mirror cluster of the distributed virtual volume.

# of Blocks

The number of blocks in the extent.

Block Size

The size of a single block, in kilobytes.

Capacity

The total number of bytes in the virtual volume. This total represents the block size multiplied by the block count.

Used

The total amount of used capacity.

Consistency Group

The name of the consistency group to which this volume belongs, if any.

Expandable

Indicates if the virtual volume is expandable.

# of Devices

Number of devices in the virtual volume.

Health State

Health state of the virtual volume. Possible values:

Major Failure = One or more of the virtual volume's underlying devices is out-of-date, but will never rebuilt.

Minor Failure = One or more of the virtual volumes underlying devices is out-of-date, but will rebuild.

Non-Recoverable Error = VPLEX cannot determine the virtual volume's health state.

OK = The virtual volume is functioning normally,

Unknown = VPLEX cannot determine the virtual volume's health state, or the state is invalid.

Locality

Locality of the virtual volume. Possible values:

Local = The virtual volume relies completely on storage at its containing cluster.

Remote = The virtual volume is a proxy for a volume whose storage resides at a different cluster. I/O to a remote virtual volume travels between clusters.

Distributed = The virtual volume is the cluster local representation of a distributed RAID-1. Writes to a distributed volume travels to all the clusters for which it has storage; reads derive, if possible, from the local leg.

Oper State

Operational status of the virtual volume. Possible values:

Degraded = The virtual volume may have one or more out-of-date devices that will eventually rebuild.

Error = One or more of the virtual volume's underlying devices is hardware-dead.

OK = The virtual volume is functioning normally.

Starting = The virtual volume is not ready.

Stressed = One or more of the virtual volume's underlying devices is out-of-date and will never rebuild.

Unknown = VPLEX cannot determine the virtual volume's operational state, or the state is invalid.

Storage Tier

The storage tier for the virtual volume.

Supporting Device

The local, remote, or distributed device underlying this volume.

Volume Type

Volume type, which is always set to virtual volume.

# of Hosts

Number of hosts that allocated LUNs.

Host LUN

The LUN to which the host is mapped.

Array Port WWN

List of Array Port WWN for each logical unit This is the list of Array Port WWN List for all logical unit.
