Parameters

-nohdr
(Optional) By default, headings are displayed for each column of data in a concise style view, and for each item of data in a detailed style view. The -nohdr parameter suppresses the display of these headings.
Remember: If no data exists to be displayed, headings are not displayed.
-bytes
(Optional) Displays all capacities as bytes. Capacity values that are displayed in units other than bytes might be rounded.
-delim delimiter
(Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a 1-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.
-copy copy_id
(Optional) Specifies the volume copy to list information for. You must specify a vdisk_name | vdisk_id value with this parameter.
-filtervalue?
(Optional) Displays a list of valid filter attributes. The following filters for the lsvdiskcopy command are valid:
  • primary
  • status
  • sync
  • mdisk_grp_id
  • mdisk_grp_name
  • type
  • easy_tier
  • easy_tier_status
vdisk_name | vdisk_id
(Optional) Specifies the volume to list copy information for. You must specify this parameter last on the command line. If you specify a vdisk_name | vdisk_id value only, all copies for the volume are listed.

Description

The lsvdiskcopy command lists information for volume copies. If you specify the command with no parameters, all volumes and copies in the clustered system are listed.

The command returns values for the following volume copy attributes:
copy_id
Specifies a system-assigned identifier for the volume copy. The value can be 0 or 1.
status
Indicates the status. The value can be online, offline, or deleting. A copy is offline if all nodes cannot access the storage pool that contains the copy.
sync
Indicates whether the volume copy is synchronized.
auto_delete
Indicates that the primary copy is deleted after the secondary copy is synchronized. The values are yes or no.
primary
Indicates whether the volume copy is the primary copy. A volume has exactly one primary copy. The value can be yes or no.
mdiskgrp_id
Indicates the ID of the storage pool that the volume copy belongs to.
mdiskgrp_name
Indicates the name of the storage pool that the volume copy belongs to.
type
Indicates the virtualization type of the volume. The value can be striped, sequential, or image.
mdisk_id
Indicates the MDisk ID that is used for sequential and image mode volumes.
mdisk_name
Indicates the MDisk name that is used for sequential and image mode volumes.
fast_write_state
Indicates the cache state of the volume copy. The value can be empty, not_empty, corrupt, or repairing. The value is always empty for non-thin-provisioned copies. A cache state of corrupt indicates that the volume is thin-provisioned and requires repair that is initiated by a recovervdisk command or the repairsevdiskcopy command.
used_capacity
Indicates the portion of real_capacity that is being used to store data. For non-thin-provisioned copies, this value is the same as the volume capacity. If the volume copy is thin-provisioned, the value increases from zero to the real_capacity value as more of the volume is written to.
Remember:
  • This value is the same as the volume capacity value for standard-provisioned copies.
  • This field is blank for volume copies that are thin-provisioned or compressed volume copies in a data reduction pool.
real_capacity
Indicates the amount of physical storage that is allocated from a storage pool to this volume copy. If the volume copy is not thin-provisioned, the value is the same as the volume capacity. If the volume copy is thin-provisioned, the value can be different.
Remember:
  • This value is the same as the volume capacity value for standard-provisioned copies.
  • This field is blank for volume copies that are thin-provisioned or compressed volume copies in a data reduction pool.
free_capacity
Indicates the difference between the real_capacity and used_capacity values.
Remember:
  • This value is 0 for standard-provisioned copies.
  • This field is blank for volume copies that are thin-provisioned or compressed volume copies in a data reduction pool.
Remember: This value is zero for standard-provisioned copies.
overallocation
Expressed as a percentage, indicates the ratio of volume capacity to real_capacity values. This value is always 100 for non-thin-provisioned volumes.
Remember: This field is blank for storage pools that are not thin-provisioned or compressed volume copies in a data reduction pool.
autoexpand
Indicates whether autoexpand is enabled on a thin-provisioned volume. The value can be on or off.
warning
Expressed as a percentage of the volume capacity for thin-provisioned or compressed volume copies, indicates that a warning is generated when the ratio of used_capacity to volume capacity reaches the specified level.
Remember: This field is blank for storage pools that are not thin-provisioned or compressed volume copies in a data reduction pool.
grainsize
For thin-provisioned volume copies, indicates the grain size that is chosen for the volume copy when it was created.
Remember: This value is always blank for compressed volume copies in regular storage pools.
se_copy
Specifies whether the copy is thin-provisioned.
easy_tier
Indicates whether Easy Tier® is permitted to manage the pool.
Remember:
  1. If easy_tier is on, then easy_tier_status can take on any value.
  2. If easy_tier is off, then easy_tier_status is measured or inactive.
easy_tier_status
Indicates which Easy Tier functions are active for the volume copy:
  • active indicates that a pool is being managed by Easy Tier to provide tier management performance-based pool balancing. For example, extents of this volume copy can be moved for performance (automatic data placement).
  • inactive indicates that no Easy Tier function is active.
  • balanced indicates that a pool is being managed by Easy Tier to provide performance-based pool balancing (for example, extents can be moved).
  • measured indicates that statistics are being gathered for this volume copy, but no extents are moved.
Table 1. Easy Tier setting for storage pools and volumes
Storage pool Easy Tier setting Number of tiers in the storage pool Volume copy Easy Tier setting Volume copy Easy Tier status
Off One Off inactive (see note 1)
Off One On inactive (see note 1)
Off Two Off inactive (see note 1)
Off Two On inactive (see note 1)
Measure One Off measured (see note 2)
Measure One On measured (see note 2)
Measure Two Off measured (see note 2)
Measure Two On measured (see note 2)
Auto One Off measured (see note 2)
Auto One On balanced (see note 3)
Auto Two Off measured (see note 2)
Auto Two On active (see note 4)
On One Off measured (see note 2)
On One On balanced (see note 3)
On Two Off measured (see note 2)
On Two On active (see note 4)
Notes:
  1. When the volume copy status is inactive, no Easy Tier functions are enabled for that volume copy.
  2. When the volume copy status is measured, the Easy Tier function collects usage statistics for the volume but automatic data placement is not active.
  3. When the volume copy status is balanced, the Easy Tier function enables performance-based pool balancing for that volume copy.
  4. When the volume copy status is active, the Easy Tier function operates in automatic data placement mode for that volume.

If the volume copy is in image or sequential mode or is being migrated, then the volume copy Easy Tier status is measured instead of active.

The default Easy Tier setting for a storage pool is auto, and the default Easy Tier setting for a volume copy is on. If the setting is on, it means that Easy Tier functions except pool performance balancing are disabled for storage pools with a single tier, and that automatic data placement mode is enabled for all striped volume copies in a storage pool with two or more tiers.

tier
Indicates which tier information is being reported:
  • tier0_flash
  • tier1_flash
  • tier_enterprise
  • tier_nearline
  • tier_scm
tier_capacity
Indicates the total MDisk capacity that is assigned to the volume in the tier.
Important: For thin-provisioned copies, the capacity by tier is the real capacity.
Important: By design, tier_capacity reports blank for thin-provisioned and compressed copies in data reduction pools.
compressed_copy
Indicates whether the volume copy is compressed.
uncompressed_used_capacity
For compressed volume copies, indicates the amount of data written to the volume copy before compression. This field is blank for volume copies in a data reduction storage pool.
used_capacity_before_reduction
Indicates the total amount of data written to a thin-provisioned or compressed volume copy in a data reduction storage pool before data reduction occurs. This field is blank for standard-provisioned volume copies and volume copies not in a data reduction pool.
parent_mdisk_grp_id
Indicates the physical storage pool ID that the volume extents are allocated from. This value is a numeric string (in the range 0 - 127 characters) or blank.
parent_mdisk_grp_name
Indicates the physical storage pool name that the volume extents are allocated from. This value is an alphanumeric string (in the range 1 - 63 characters) or blank.
