lsarray

Use the lsarray command to list the array MDisks.

Syntax

lsarray [ -nohdr ] [ -delimdelimiter ] [ -bytes ] [ -filtervalue? ] { [ -filtervalueattribute=value ] | [ -filtervaluecapacity=value -unit { b | kb | mb | gb | tb | pb } ] } [ { mdisk_id | mdisk_name } ]

Parameters

-nohdr

(Optional) By default, headings are displayed 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.

-delim delimiter

(Optional) 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. In a detailed view, the data is separated from its header by the specified delimiter.

-bytes

(Optional) Requests output of capacities in bytes (instead of rounded values).

-filtervalue?

(Optional) Includes all of the valid filter attributes in the report. The following filter attributes are valid for the lsarray command:

balanced
capacity
distributed
mdisk_id
mdisk_name
mode
mdisk_grp_id
mdisk_grp_name
fast_write_state
raid_status
raid_level
redundancy
spare_goal
spare_protection_min
status
strip_size
tier
easy_tier_load

Any parameters that are specified with the -filtervalue? parameter are ignored.

-filtervalueattribute=value

(Optional) Specifies a list of one or more filter attributes match the specified values; see -filtervalue? for the supported attributes. Only objects with a value that matches the filter attribute value are returned. If capacity is specified, the units must also be included. Use the unit parameter to interpret the value for size or capacity.

Note: Some filters allow the use of a wildcard when you enter the command. The following rules apply to the use of wildcards when you use the 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 you use a wildcard character, you must enclose the filter entry within double quotation marks (""):
```
lsarray -filtervalue  "name=md*"
```

-filtervaluecapacity=value

(Optional) Specifies a list of one or more filter capacities (size) values matching the specified values for the unit parameter. Use the unit parameter to interpret the value for size or capacity.

-unitb | kb | mb | gb | tb | pb

(Optional) The units that are used when you specify the -filtervalue capacity, where:

b = bytes
kb = 1,024 bytes
mb = 1,048,576 bytes
gb = 1,073,741,824 bytes
tb = 1,099,511,627,776 bytes
pb = 1,125,899,906,842,624 bytes

mdisk_id

(Optional) The identity of the array MDisk.

mdisk_name

(Optional) The name of the array MDisk.

Description

This command returns a concise list or a detailed view of array MDisks visible to the system. This table provides the attribute values that can be displayed as output view data.

Table 1. Array output
Attribute	Values
capacity	Indicates the value for the capacity you specify by using the -unit parameter.
status	Indicates the array status. The values are: online offline excluded degraded (applies only to internal MDisks)
mode	Indicates the mode. The values are: `unmanaged` `managed` `image` `array`
quorum_index	Indicates the quorum index. The values are: `0` `1` `2` Blank if the MDisk is not being used as a quorum disk.
block_size	Indicates the block size. The value is `512` bytes (or blank) in each block of storage.
ctrl_type	`4`, `6`, where `6` is a flash drive attached inside a node and 4 is any other device.
raid_status	Indicates the RAID status. The values are: offline The array is offline on all nodes. degraded The array has deconfigured or offline members; the array is not fully redundant. syncing The array members are all online. The array is synchronizing parity or mirrors to achieve redundancy. initializing The array members are all online. The array is initializing; the array is fully redundant. online The array members are all online, and the array is fully redundant.
fast_write_state	Indicates the cache state of the array. The values are: `empty`, which indicates that the array disk data is not changing. `not_empty`, which indicates that the array disk data might change. `corrupt`, which indicates that the array disk data is lost and the array is corrupt. Repair can be initiated by using the recoverarray or recoverarraybysystem command.
raid_level	Indicates the RAID level of the array. The values are: `RAID0` `RAID1` `RAID5` `RAID6` `RAID10`
redundancy	Indicates the number of member disks that can fail concurrently without causing the array to fail.
strip_size	Indicates the strip size of the array (in KB).
spare_goal	Indicates the number of spares that the array members must be protected by. For distributed arrays, this value is blank.
spare_protection_min	Indicates the minimum number of spares that an array member is protected by. For distributed arrays, this value is blank.
balanced	For nondistributed arrays, this value indicates whether the array is balanced to its spare goals: `exact` indicates that all populated members have the same (matching) capability and location. `yes` indicates that all populated members have at least the same capability and chain, but a different enclosure or slot. `no` indicates that it is unbalanced. For distributed arrays, this value indicates whether a superior drive class is being used for the array: `exact` indicates that the same drive class is in use. `yes` indicates that at least one array member exceeds the array drive class. For distributed arrays, the array must also be balanced to its rebuild area goals.
tier	Indicates the tier that this array is assigned to by auto-detection (for internal arrays) or by the user: `tier0_flash` `tier1_flash` `tier_enterprise` `tier_nearline` Note: Use the chmdisk command to change this value.
replacement_date	Indicates the date of a potential array failure. The format must be `YYMMDD`.
easy_tier_load	Indicates the value for Easy Tier settings, and is either blank (for arrays) or one of the following values (for MDisks): `low` `medium` `high` `very_high`
slow_write_priority	Indicates the response time goal: `latency` indicates that the array is taken out of synchronization to quickly complete write operations that take excessive time. `redundancy` indicates slow write operations are completed in normal time and the arrays remain synchronized.
site_id	Indicates the site value for the storage pool. This numeric value is `1`, `2`, `3`, or blank.
site_name	Indicates the site name for the storage pool. This value is alphanumeric or is blank.
fabric_type	Indicates a Fibre Channel (FC), SAS, or another type of array. `fc` indicates an array from an FC controller. `sas_direct` indicates an array from an SAS direct-attached controller.
distributed	Indicates whether the array is distributed. The values are `yes` or `no`.
drive_class_id	Indicates the drive class that makes up this array. If -allowsuperior was used during array creation, the lowest used drive class ID is displayed. This value is blank for nondistributed arrays.
drive_count	Indicates the total width of the array, including rebuild areas. The value is a number from `4` to `128`. The minimum value for RAID-6 and RAID-10 arrays is `6`.
stripe_width	Indicates the width of a single unit of redundancy within a distributed set of drives. The values are: Any number from `3` - `16` for RAID-5 arrays. Any number from `4` - `16` for RAID-6 arrays. An even number from `2` - `16` for RAID-10 arrays.
rebuild_areas_total	Indicates the total number of rebuild areas set when the array is created. These rebuild areas provide performance but no capacity. The value is `1` - `4` for distributed array RAID-5 and distributed array RAID-6. The value is blank for nondistributed arrays.
rebuild_areas_available	Indicates the number of remaining rebuild areas within the set of drives. The value is `1` - `4` for distributed array RAID-5 and distributed array RAID-6. The value is blank for nondistributed arrays.
rebuild_areas_goal	Indicates the rebuild areas threshold (minimum limit) at which point the array logs an error. The value is `1` - `4` for distributed array RAID-5 and distributed array RAID-6. The value is blank for nondistributed arrays.
over_provisioned	Shows `yes` if the MDisk is thin-provisioned. Shows `no` if the disk is marked as fully allocated, resource-provisioned, or the information cannot be determined.
supports_unmap	Shows `yes` if the MDisk indicates UNMAP support. Shows `no` if the disk indicates it does not support UNMAP, or the information cannot be identified.
provisioning_group_id	System allocated identifier of the provisioning group that relates to the MDisk. This identifier is used to identify the list of MDisks that are provided by the same provisioning group.
physical_capacity	The total physical storage capacity of the provisioning group providing this MDisk. If this disk is not `over_provisioned`, then logical capacity is reported here.
physical_free_capacity	The amount of formatted available physical space in the provisioning group providing this MDisk. If this disk is not `over_provisioned`, then remaining logical capacity is reported here.
write_protected	Shows `yes` if the array is in the write protected state, otherwise `no`.
data_reduced	Indicates that the MDisk data is reduced. The values are `yes` or `no`.
effective_used_capacity	The amount of logical data that is written to the MDisk. If this MDisk is not `over_provisioned`, then this field is blank.
allocated_capacity	The amount of logical capacity that is allocated (by a pool) from this array for volume data and quorum.

This list defines the status fields:

online: The MDisk is online and available.
degraded: (Internal MDisks only) The array has members that are degraded, or the raid_status is degraded.
degraded_ports: There are one or more MDisk port errors.
degraded_paths: One or more paths to the MDisk are lost; the MDisk is not online to every node in the system.
offline: All paths to the MDisk are lost.
excluded: The MDisk is excluded from use by the system; the MDisk port error count exceeded the threshold.
