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)  Section 3.4, Using the Detail Tabs (page 50)  Section 3.5, Removing iSCSI Initiators (page 59) xStack Storage Management Center Software User's Guide 27

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:
