Use the lssevdiskcopy command to list the thin-provisioned
copies of the specified volumes.
Syntax
lssevdiskcopy [ -nohdr ] [ -bytes ] [ -delimdelimiter ] [ -copyid ] [ -filtervalue? ] [ { 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 is
available 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.
- -copyid
- (Optional) Specifies the volume copy to list
thin-provisioned copies 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
lssevdiskcopy command are valid:
- mdisk_grp_id
- mdisk_grp_name
- overallocation
- autoexpand
- grainsize
- deduplicated_copy
- vdisk_name | vdisk_id
- (Optional) Specifies the volume name or ID to list
thin-provisioned copies for. You must specify this
parameter last on the command line. If you do not
enter this parameter, the command lists all
thin-provisioned copies in the clustered
system.
Description
The lssevdiskcopy command lists all
thin-provisioned copies of the specified volume. If you do not
specify a volume, the command lists all thin-provisioned volume
copies in the clustered system.
The command provides a concise
view of the thin-provisioned properties of the selected volume
copies. Run the lsvdiskcopy command to see a
concise view of the properties that are common to thin-provisioned
and non-thin-provisioned volume copies. See the description of the
lsvdisk command for a description of the
fields that are shown in the view.
The command returns values
for the following volume copy attributes:
- copy_id
- Indicates 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
field is blank for thin-provisioned and 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
field is blank for thin-provisioned and compressed
volume copies in a data reduction pool.
- free_capacity
- Indicates the difference between the
real_capacity and
used_capacity
values.
Remember: This
field is blank for thin-provisioned and compressed
volume copies in a data reduction
pool.
- 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 zero for thin-provisioned and 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, for thin-provisioned
volume copies only, indicates that a warning is
generated when the ratio of
used_capacity to
volume capacity reaches the specified level.
Remember: This
field is zero for thin-provisioned and 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
field is blank for compressed volume copies in
regular storage pools.
- se_copy
- Indicates whether the copy is thin-provisioned.
The value can be yes
or no.
- 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.
- 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).
This table describes the storage pool Easy Tier
settings.
If the volume copy is in image or
sequential mode or is being migrated, 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.
These settings mean 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.
- compressed_copy
- Indicates whether the volume copy is
compressed.
- uncompressed_used_capacity
- For
compressed volume copies, indicates the amount of
data that is 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 that is written
to a thin-provisioned or compressed volume copy in
a data reduction storage pool before data
reduction occurs. This field is blank for fully
allocated 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.
- encrypt
- Indicates whether the volume and its copies are
encrypted. The values are yes or
no.
- deduplicated_copy_count
- Indicates the number of data deduplicated volume
copies.
- deduplicated_copy
- Indicates whether the volume copy is data
deduplicated. The values are:
