zSeries volumes — Main page

Introduction

If no rows of data are displayed on this page, you must first create volumes by following the steps in the Creating zSeries volumes task. When you complete that task, the new volumes and their related values will be displayed here.

Menu path

Fields

Select

The check boxes for the volumes. Select the volumes that you want to work with for the Select Action options or for which you want to print a report or download a spreadsheet.

Nickname

The unique, user- or system-defined nickname that identifies the volume throughout the system. The link takes you to the zSeries volume properties page, which displays the volume attributes and values.

Number

The unique volume number that identifies this volume throughout the system (for example, 1E3B).

Status (Real-time only)

The label indicates the operational status. The link takes you to the zSeries volume status page, which displays values for the access, data, and configuration states.

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

Base/Alias

The type of logical volume or logical device:

• CKD (count key data) Base describes a logical volume with a host accessible logical device that has an associated logical volume.
• CKD Alias describes a logical device that is an alias for a CKD logical volume.

Volume Type

3380 Mod 2, 3380 Mod 3, 3390 Standard Mod 3, 3390 Standard Mod 9, or 3390 Custom. This is primarily a capacity attribute. For a 3380 cylinder, the logical volume is a CKD device with a 3380 track format and 16–bit cylinder addressing. For a 3390 cylinder, the logical volume is a CKD device with a 3390 track format and 16–bit cylinder addressing.

Binary GB

The volume capacity in binary gigabytes.

Decimal GB

The volume capacity in decimal gigabytes.

RAID

The RAID type of the rank from which this volume is allocated. Mixed appears only if you modified 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; however, since rank RAID type can take some time (Offline, Reconfigure mode), the RAID type remains Mixed until the conversion is complete.

Extent Pool

The unique, user-defined extent pool nickname that identifies the extent pool throughout the system.
