lsarray

Use the lsarray command to list the array MDisks.

Syntax

 lsarray    [  -nohdr  ]   [  -delim  delimiter  ]   [ -bytes ]   [  -filtervalue?  ]   { [  -filtervalue  attribute=value  ] | [  -filtervalue  capacity=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 clustered system (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
  • 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.
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.
