Table 2 LUN information (continued)

Description

Field

Logical Unit Number (LUN) in Hexadecimal, a unique identifier used on a SCSI bus
to distinguish between devices that share the same bus.

Array LUN or LUN ID

A unique 64-bit value used to identify fibre channel devices on an arbitrated loop.
The WWN consists of a prefix issued by the IEEE to uniquely identify the company
and a suffix that is issued by the company.

LUN WWN

Name of the virtual volume.

VV Name

InForm OS version number.

Code Revision

Serial number of the array from which the LUN is exposed to the host.

Array Serial Number

Name of the domain associated with the LUN.

NOTE:

If a domain is not associated, then the value of this field is set to “0”.

Domain Name

Virtual volume identifier

VV ID

Domain Identifier

Domain ID

Name of the User Common Provisioning Group (CPG) associated with the LUN. CPG
is a set of logical disks from which you can create virtual volumes and virtual copies
that are capable of allocating storage on demand.

User CPG Name

Name of the snap CPG associated with the LUN.

Snap CPG Name

Type of the provisioning — Fully Provisioned, Thinly Provisioned, or Snapshot.

Provisioning Type

Thinly Provisioned Virtual Volume allocation unit in kilobytes. If the volume is fully
provisioned, this field displays “NA” (Not Applicable).

TP VV Allocation Unit

Logical size (in megabytes) of user data for thinly-provisioned virtual volume. If the
volume is fully provisioned, this field displays “NA”.

Reserved User Size

Used User Size (in megabytes) allocated to thinly-provisioned virtual volume. If the
volume is fully provisioned, this field displays “NA”.

Used User Size

Indicates whether reclaim support is available on thinly provisioned virtual volumes.

TPVV Reclaim

Indicates whether Atomic Test and Set is supported. This is a VAAI (vStorage API for
Array Integration) capability that is used to off-load work to the storage array, and
thus reduce the host workload.

ATS Support

Indicates whether XCOPY is supported. This is a VAAI (vStorage API for Array
Integration) capability that is used to off-load work to the storage array, and thus
reduce the host workload.

XCOPY Support

Log files

Logs are generated by default whenever you run the HP3PARInfo command. You can find the
log files at the following location:

On Linux, AIX, ESX and ESXi — /var/log/HP3PARInfo/

On HP-UX — /var/adm/HP3PARInfo/

On Windows — Folder in which HP 3PARInfo is installed.

HP 3PARInfo implements a rollover logger; each time HP 3PARInfo is run, the existing log files are
rolled over. At any time, a maximum of five latest log files are present in the log directory.

When you run HP 3PARInfo for the first time, HP3PARInfo.log is created. When you run it for
the second time, the existing log file HP3PARInfo.log is renamed as HP3PARInfo.log.0,
and the new log file HP3PARInfo.log is created. Similarly, whenever a new log file is created,
the older log files are renamed. But, only the five latest log files are retained in the log directory.
