Fields

Select storage unit

Provides a list of the storage unit that can be configured. This field acts as a primary filter for the information that is displayed on this page.

Select secondary filter

Provides a list of the type of objects that can be modified: LSSs, Hosts, Volume groups or all volumes associated with the storage unit.

Select LSS

Provides a list of individual LSSs that are associated with the storage unit. Select an LSS to provide a list of its associated volumes that can be modified.

Select host attachment

Provides a list of individual host attachments that are associated with the storage unit. Select a host attachment to provide a list of its associated volumes that can be modified.

Select volume group

Provides a list of individual volume groups that are associated with the storage unit. Select a volume group to provide a list of the associated volumes that can be modified.

Select All

Provides a list of all the volumes that are associated with the storage unit that can be modified.

Select

Provides the selection method (a check box) for specifying the volume you want to modify. When you click a check box, the Select Action drop down list is refreshed with a list of modifying actions that you can enact on each volume that you select.

Nickname

Specifies the user- or system-designated nickname. The link takes you to a properties page for the selected value.

Number

Specifies a logical subsystem number and a logical device number (for example, 1E3B). The volume number is four hexadecimal characters (0 - 9 or uppercase A - F).

Status (Real-time only)

Specifies the operational status. The link takes you to a volume status page.

Normal

The volume is in the following state:

• Access state
  • Online
• Data state
  • Normal
  • Read only
• Configuration state
  • Normal
  • Configuring
  • Deconfiguring

Attention

The volume is in the following state:

• Data state
  • Pinned
  • Rank failed
  • Rank repairing
  • Rank repaired
  • Unknown

Failed

The storage unit is in the following state:

• Access state
  • Fenced
• Configuration state
  • Configuration error

Note: The configuration error state indicates that the initial configuration of the volume did not complete successfully. If one or more of the configured volumes displays the configuration error state, you must delete each one. You can recreate them later.

Inaccessible

The storage unit is in the following state:

• Access state
  • Fenced
• Data state
  • Inaccessible

Type

Specifies the type of the capacity unit at the time of volume creation. One of the following volume types is displayed:

DS

Supported DS logical volume sizes range from 1 to 2048 binary gigabytes (1GB = 2³⁰ bytes). This allocation uses the storage capacity of DS systems most efficiently.

ES

Supported Enterprise Storage System (ESS) logical volume sizes range from 0.1 to 982.2 decimal gigabytes (1GB = 10⁹ bytes). You can calculate the exact number of 512 byte blocks as INT((INT(GBx10⁹/512)+63)/64)x64. The size of the volume that is created on the ESS is identical to the size of the volume that is created on the DS. However, the last extent on the volume might not be fully used because these sizes are not an integral multiple of the extent size.

Blocks

Supported block logical volume sizes range from 1 to 4 binary gigablocks (1 gigablock = 2³⁰ 512-byte blocks). If a specified size matches a supported DS or ESS logical volume size, the volume is identified as a DS or ESS logical volume, even though it is created by specifying the blocks volume type.

iSeries

Indicates that this volume uses a capacity algorithm that is specific to iSeries volumes.

I-protected

Indicates that this volume uses a capacity algorithm specific to iSeries volumes and that the volume is in the protected state.

I-unprotected

Indicates that this volume uses a capacity algorithm that is specific to iSeries volumes and that the volume is in the unprotected state.

GB (2³⁰)

Specifies the volume capacity in binary gigabytes.

Decimal GB (10⁹)

Specifies the volume capacity in decimal gigabytes.

RAID

Specifies the type of RAID array (for example, 5 or 10). A mixed RAID type is displayed when you modify the RAID type of the ranks in the extent pool. The label remains mixed if you chose not to convert the existing ranks to the newly selected RAID type. Even when you initiate the conversion, the processing time can take some time to complete. The RAID type remains mixed until the conversion is complete.

Extent Pool

Specifies the user- or system-designated extent pool nickname.

Volume Groups

Specifies the volume group nickname. If the quantity of volume groups exceeds 1, the value is the quantity of volume groups with which this volume is associated. The link takes you to Volume Groups — Main page.

Host Attachments

Specifies the quantity of host attachments to which the designated volume is attached using volume groups. This is a function of the number of host attachments that are associated with the volume groups to which this volume belongs. The link takes you to Host Systems — Main page.

Actions

The following actions are available from the Select Action drop-down list after you have selected your LSS, host, or volume group. To initiate one of these actions, click it and then click GO.

Create

When Create is selected, the Create open systems volumes Wizard page is displayed. This action can be selected before you select a specific LSS, host, or volume group.

Delete

When Delete is selected, a confirmation dialog in invoked and if confirmed, the selected open system volumes are deleted.

Note: If all volumes on a particular LSS are deleted, the LSS is deleted if the storage type is fixed block but not if the storage type is CKD.

Add to volume group

When this action is selected, the Add to Volume Group page is displayed.

Note: This action is only available when at least one volume group already exists and you have specifically selected one or more volume groups from the list.

Status

When Status is selected, the status page for open systems volumes with detailed information for the selected volumes is displayed.

Advanced operations

When Advanced operations is selected, the advance operations page for open systems volumes is displayed. You select advanced operations when a volume is reported with an unfenced status.

Properties

When Properties is selected, the Volume Properties page where you can change the nickname that is associated with the volume is displayed.

Note: This action is not available when you select more than one volume.
