lsmdiskgrp

Use the lsmdiskgrp command to display a concise list or a detailed view of storage pools that are visible to the clustered system (system).

Syntax

lsmdiskgrp [ -filtervalue attribute=value ] [ -nohdr ] [ -bytes ] [ -delim delimiter ] [ -filtervalue? ] [ { object_id | object_name } ]

Parameters

-filtervalueattribute=value

(Optional) Specifies a list of one or more filters. Only objects with a value that matches the filter attribute value are returned. If a capacity is specified, the units must also be included.

Note: Some filters allow the use of a wildcard when you enter the command. The following rules apply to the use of wildcards when using the command-line interface (CLI):

The wildcard character is an asterisk (*).
The command can contain a maximum of one wildcard, which must be the first or last character in the string.
When using a wildcard, you must enclose the filter entry within double quotation marks (""), as follows:
```
lsmdiskgrp -filtervalue  "name=md*"
```

-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 there is no data to be displayed, headings are not displayed.

-bytes

(Optional) Specifies that you want the report to display all capacities as bytes.

-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 possible 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 one 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.

object_id | object_name

(Optional) Specifies the name or ID of an object. When you use this parameter, the detailed view of the specific object is returned and any value specified by the -filtervalue parameter is ignored. If you do not specify the object_id | object_name parameter, the concise view of all objects matching the filtering requirements specified by the -filtervalue parameter are displayed.

-filtervalue?

(Optional) Displays a list of valid filter attributes. The valid filters for the lsmdiskgrp command are:

name
id
mdisk_count
vdisk_count
status
storage_pool_id
easy_tier
easy_tier_status
site_id
site_name
parent_mdisk_grp_id
parent_mdisk_grp_name
child_mdisk_grp_count
type
encrypt
owner_type

For more information about filtering attributes, see Attributes of the -filtervalue parameters.

Description

This command returns a concise list or a detailed view of storage pools visible to the system.

Command output includes values for the following attributes:

status

The state of the MDisk with the highest-priority status in the group, excluding image mode MDisks.

VDisk_count

The number of volume copies that are in the storage pool.

capacity

The total amount of MDisk storage that is assigned to the storage pool.

extent_size

The size of the extents for this group: 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, or 8192 (MB).

free_capacity

The amount of MDisk storage that is assigned to the storage pool that is unused. MDisk storage can be used for system quorum data and volumes.

real_capacity

The amount of MDisk storage that is assigned to the storage pool that is assigned to volumes.

virtual_capacity

The total virtual size of all the volume copies that are associated with the storage pool. This is the same as the real_capacity value unless you have configured thin-provisioned volume copies in this storage pool.

used_capacity

The total used size of all the volume copies that are associated with the storage pool. This is the same as the real_capacity value unless you have configured thin-provisioned volume copies in this storage pool.

overallocation

Expressed as a percentage, the ratio of the virtual_capacity value to the capacity. An storage pool overallocation of over 100 is only possible if you have configured thin-provisioned volume copies.

warning

This field is a percentage. A warning is generated when the amount of space in the storage pool that has been assigned exceeds this level.

easy_tier

This value is set by the user and determines whether Easy Tier is permitted to manage the pool.

Note: The values are:

on, which indicates Easy Tier actively manages the extents (including single-tier storage pools), and the Easy Tier status should be active - unless a license is required.
off, which indicates Easy Tier does not actively manage the extents, and the Easy Tier status should be inactive .
auto, which indicates the value of Easy Tier status is determined by the number of tiers an storage pool has.
Note: auto, which indicates:
- on if Easy Tier is licensed or no license is required
- off if Easy Tier requires a license and none exists
measure indicates Easy Tier s collects statistics on that storage pool but does not move any extents in the storage pool.

easy_tier_status

Whether the Easy Tier functions are active on an storage pool:

active indicates a pool is being managed by Easy Tier to provide tier management performance-based pool balancing (for example, extents can be moved).
inactive indicates Easy Tier is inactive
measured indicates Easy Tier statistics are being collected but no Easy Tier management is detected.
balanced indicates 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:

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 2)
Off	One	On	inactive (see note 2)
Off	Two	Off	inactive (see note 2)
Off	Two	On	inactive (see note 2)
Measure	One	Off	measured (see note 3)
Measure	One	On	measured (see note 3)
Measure	Two	Off	measured (see note 3)
Measure	Two	On	measured (see note 3)
Auto	One	Off	measured (see note 3)
Auto	One	On	balanced (see note 4)
Auto	Two	Off	measured (see note 3)
Auto	Two	On	active (see note 5)
On	One	Off	balanced (see note 4)
On	One	On	balanced (see note 4)
On	Two	Off	measured (see note 3)
On	Two	On	active (see note 5)
Note: If the volume copy is in image or sequential mode or is being migrated then the volume copy Easy Tier(tm) status is `measured` instead of `active`. When the volume copy status is `inactive`, no Easy Tier(tm) functions are enabled for that volume copy. When the volume copy status is `measured`, the Easy Tier(tm) function collects usage statistics for the volume but automatic data placement is not active. When the volume copy status is `balanced`, the Easy Tier(tm) function enables performance-based pool balancing for that volume copy. When the volume copy status is `active`, the Easy Tier(tm) function operates in automatic data placement mode for that volume. The default Easy Tier setting for a storage pool is `auto`, and the default Easy Tier setting for a volume copy is `on`. This means that Easy Tier functions other than 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.
