Use the lsvdiskcopy command to list volume copy
information.
Syntax
lsvdiskcopy [ -nohdr ] [ -bytes ] [ -delim delimiter ] [ -filtervalue? ] [ { { vdisk_name | vdisk_id } | -copy copy_id { vdisk_name | vdisk_id } } ]
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.
Note: 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.
- -delimdelimiter
- (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.
- -copycopy_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 system status. The value can be online or
offline. 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 fully allocated copies.
- This field is blank for storage pools that are not 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 fully allocated copies.
- This field is blank for storage pools that are not 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 fully allocated copies.
- This field is blank for storage pools that are not thin-provisioned or compressed
volume copies in a data reduction pool.
Remember: This value is zero for fully allocated 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.
- se_copy
- Specifies whether the copy is thin-provisioned.
- easy_tier
- Indicates whether Easy Tier is permitted to
manage the pool.
Note: - If easy_tier is on, then easy_tier_status can take on any
value.
- 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.
- balanced indicates that a pool is being managed by Easy Tier to provide performance-based pool balancing (for
example, extents can be moved).
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_capacity
- Indicates the total MDisk capacity that is assigned to the volume in the tier.
Note: For
thin-provisioned copies, the capacity by tier is the real capacity.
Note: By design,
tier_capacity reports 0.00MB for
thin-provisioned and compressed copies in data reduction pools.
- compressed_copy
- Indicates whether the volume copy is compressed.
- uncompressed_used_capacity
- For compressed volumes, indicates the amount of data that is written to the volume before
compression.
Remember: This field is blank for storage pools
that are not thin-provisioned or compressed volume copies in a data reduction
pool.
- used_capacity_before_reduction
- Indicates the total amount of data that was written to thin-provisioned and compressed
volume copies in the storage pool before data reduction occurs. This value does not include
fully allocated volumes (that can be created in a data reduction pool) because they are not
eligible for reduction. This field is blank for storage pools that are not thin-provisioned
or compressed volume copies 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.
- encrypt
- Indicates whether the volume and its copies are encrypted. The values are
yes or no.
