lssp command

Purpose

Lists and displays information about storage pools.

Syntax

To list all available storage pools:

lssp [ -type PoolType [-field FieldName ] [ -fmt Delimiter ]

To display information about a specific storage pool:

lssp -detail | -bd [-sp StoragePool] [-field FieldName ] [-fmt Delimiter ]

To display the default storage pool:

lssp -default

To display all the VIOS cluster objects in a shared storage pool:

lssp -clustername ClusterName -sp StoragePool -bd [-field FieldName ] [ -fmt Delimiter ]

To display storage pools in a specific cluster:

lssp -clustername ClusterName [-field FieldName ] [ -fmt Delimiter ]

Description

The lssp command displays information about storage pools in the Virtual I/O Server (VIOS). If no flags are specified, a list of all defined storage pools, their total size, free space, minimum allocation size, and number of backing devices contained in the pool and the type of pool is displayed. If the -type flag is specified only storage pools of the indicated type are displayed. If the -detail flag is specified, detailed information about the storage pool is displayed. If the -bd flag is specified, a list of all the backing devices in the specified (or default) storage pool is displayed along with their size and associated virtual target device, or None, and virtual host adapter, or None. If the -default flag is specified, the default storage pool is displayed.

This command provides full scripting support through the use of the -field and -fmt flags.

Note: If the LU is fully written, an additional space including space for metadata is required for a thin-provisioned LU.

Flags

Flag name	Description
-clustername ClusterName	Specifies the cluster name to list the storage pools.
-default	Displays the default storage pool.
-field FieldName	The following fields are supported if no flags are specified: pool Storage pool name size Total size free Free space alloc Minimum allocation size bds The number of backing devices. type Type of pool The following fields are supported if the -detail flag is specified for a logical volume pool: pvname Name of the physical volume. pvid Physical volume identifier size The size of the physical volume. The following fields are supported if the -detail flag is specified for a file pool: name Name of the parent storage pool. The following fields are supported if the -bd flag is specified: bdname Backing device name. size The size of the logical volume. vtd Virtual target device. svsa Server virtual SCSI adapter. The following fields are supported if the -clustername , -spname, and -bd flags are specified: luname The name of the logical unit. size The size of the logical volume. provisiontype The provision type of the logical unit (THIN or THICK). usage The current used data space of the logical unit. unused The current free data space of the logical unit. luudid The unique device ID of the logical unit. The following fields are supported if the -clustername flag is specified without specifying the -sp flag: pool The name of the storage pool.
	size The total size of the storage pool. free The current free data space of the storage pool. total The total size of the logical unit, which is a sum of the size of all the logical units. overcommit The current overcommit size of the storage pool. lus The total number of logical units. type The type of the storage pool. id The ID of the storage pool.
-fmt Delimiter	Specifies a delimiter character to separate output fields.
-bd	Displays information about the backing devices or logical units in the storage pool.
-detail	Displays detailed information about the file that is backed up and the logical volume-based storage pool.
-sp StoragePool	Specifies which storage pool to display information about.
-type PoolType	Specifies the type of pool to list. The following fields are supported: lvpool List only logical volume pools. fbpool List only file pools.

Examples

To list all the storage pools, type the following command:

lssp

The system displays the following output:

Pool             Size(mb) Free(mb) Alloc Size(mb) BDs Type
PRODClient       30624    28576    32    0        LVPOOL
rootvg           30656    14208    64    0        LVPOOL
DEVClient        18352    18352    16    0        LVPOOL

PRODClient_FBP2  1016     1005     32    1        FBPOOL

To display the default storage pool, type the following command:
```
lssp -default
```

To display detailed information about the logical volume storage pool sp_sp00, type the following command:

lssp -detail -sp sp_sp00

The system displays the following output:

NAME       PVID                  SIZE(megabytes)
hdisk3     00cdfd8c85bd4b2e      34624
hdisk2     00cdfd8c525d94a2      34624

To display information about the backing devices in the logical volume storage pool rootvg, type the following command:
```
lssp -bd -sp rootvg
```
The system displays the following output:
```
NAME    SIZE(megabytes)   VTD       SVSA
lv01    96                vtscsi1   vhost0
lv02    64                vtscsi2   vhost0 
```

To list all storage pools within a cluster, type the following command:

lssp -clustername newcluster

The system displays the following output:

POOL_NAME: SP
POOL_SIZE: 714240
MIRROR_STATE: SYNCED
FREE_SPACE: 702047
TOTAL_LU_SIZE: 10240
OVERCOMMIT_SIZE: 0
TOTAL_LUS: 15
POOL_TYPE: CLPOOL
POOL_ID: 000000000903311C000000004F42A526

To list all VIOS cluster objects in a shared storage pool, type the following command:

lssp -clustername newcluster -sp SP -bd | more

Note: If the logical unit is fully written, an additional space including space for metadata is required for a thin-provisioned logical unit.

The system displays the following output:
