HP-UX vPars and Integrity VM V6.3 Administrator Guide

6.5 Using vPars and Integrity VM storage
The following sections describe the roles of individuals accessing virtual storage, the commands
they use, and some examples of using vPars and Integrity VM storage.
6.5.1 Storage roles
This section describes the roles of individuals in working with vPars or VM guests storage. Each
role has different responsibilities in using vPars or VM guests storage. The roles might be played
by one or more individuals depending on security requirements and skill sets. The three roles are:
• VSP administrator
• Guest administrator
• Guest user
For more information about creating vPar or VM guest administrator and operator accounts, see
Section 13.10 (page 225).
6.5.1.1 VSP administrator
The VSP administrator is responsible for the proper configuration and maintenance of the VSP for
running vPars and VM guests. As such, this person needs complete access to the VSP to install
hardware and software. This person must also know about HP-UX system maintenance, hardware
configuration, and setting up and using various software applications and tools.
The VSP administrator uses the following commands to manage vPar or VM guest storage devices:
Integrity VM commandManagement function
hpvmmodify (see Section 9.4 (page 142))Add, delete, manage, and modify vPar/VM storage
devices.
hpvmstatus (see Section 13.1 (page 217))Display information about the storage devices for a
vPar/VM.
After a resource is added or attached to a vPar or VM guest and it is online, the storage resource
seen by the guest is owned by the guest administrator. That is, the guest OS may access that
storage resource at any time. A deletion, detachment, or modification fails if any guest I/O is
active on the resource. Dynamic storage changes on an active vPar or VM must be approved by
the guest administrator.
6.5.1.2 Guest administrator
The vPar or VM Guest Administrator is responsible for the proper maintenance of a guest OS. The
VSP administrator must provide the guest administrator access to the virtual console to control the
vPar or VM. The guest administrator must know how to maintain the guest OS, install patches and
applications, and set up security for the guest users of the guest OS. Additionally, vPar or VM
guests storage requires you to:
• Install any specific guest OS patches required by vPars and Integrity VM for proper OS
operation on the virtual platform.
• Review and understand any vPar or VM guests storage release notes that are specific to the
guest OS.
• Work with the VSP administrator to complete virtual storage changes, including managing
attached VSP devices.
The guest administrator uses the virtual console to modify virtual storage. The virtual console is
used to change discs of a virtual DVD device type. All modifications are bound by the configurations
created by the VSP administrator for the VM.
