Chapter 3 Managing Volumes

This chapter describes how to manage volumes on an xStack Storage system. A volume

is a set of storage blocks organized and presented for use by a customer’s server (an

iSCSI initiator node). The iSCSI initiator node sees the volume as a contiguous series of

numbered blocks, called Virtual Logical Block Numbers (VLBNs), in the same way that it

would see the storage space on a single disk drive. The xStack Storage system builds a

volume from extents. A volume typically consists of extents from several drives.

Volumes are managed in the Volume View. Volume View is the initial view that appears

when you log in to the xStack Storage Management Center. If you are in a different

console view, you can display the Volume View by performing any of the following

steps:

 Clicking Volume on the View menu.

 Clicking an xStack Storage IP address in the View panel.

 Clicking the Volume View button on the toolbar:

The topics covered in this chapter are:

 Section 3.1, Understanding the Volume View (page 28)

 Section 3.2, Creating Volumes (page 29)

 Section 3.3, Performing Volume Actions (page 41)
