Introduction

Chapter 1
Introduction
1.1 Overview
StorView
®
Storage Management software is a full-featured graphical HTML-based software suite
designed to configure, manage, and monitor storage subsystems. StorView is built on a modular design
and currently supports the RAID Module. Other modules available in the future are separately
documented.
The RAID Module provides an extensive set of configuration and management tools. StorView’s RAID
Module is available in two versions: host-based and embedded. The host-based version is installed on
the host computer system, while the embedded version is installed on the RAID Controller.
StorView’s server component discovers storage solutions, manages and distributes message logs, and
communicates with other server components installed on the same local network and external subnet
networks. StorView has an HTML-based front end, accessed with a web browser, and provides the
interface to the end user.
StorView incorporates web server software as part of the installation, Apache 2.0, which provides the
interface between the server component and HTML interface. During installation the web server is
automatically configured and requires no further management.The installation of the web server software
is self contained and will not conflict with other web server software currently installed on your system.
1.2 Inter-Server Communication
1.2.1 Multicast
StorView’s server component uses multicasting technology to provide inter-server communication with
other servers when the Global Access license is installed. During the server’s initial start-up, it performs
a multicast registration using the default multicast IP address of 225.0.0.225 on port 9191. Once
registration is complete, the server is able to receive all packets sent to the multicast address.

StorView RAID Module
2
All packets sent to the multicast address remain in the local network, unless an explicit server IP address
outside the subnet is added in the “Inter-Server Communication” Explicit StorView Server IPs >
Preference Settings, see 4.7 ”Monitoring Settings” beginning on page 37. The inter-server
communication abilities provide StorView with remote monitoring of other installations of StorView and
their monitored storage solutions.
StorView has the ability to communicate with any StorView installation on the local network. These other
StorView server’s are displayed on the Main screen and are listed under the “Other Servers” section.
They display the IP address, name, and a overall status of that server’s monitored storage solution. They
indicate the status of a monitored server storage solution, by the server icon changing to one of a few
different states, see 2.1.4 ”Server Sidebar and Top Section” beginning on page 17.
Each server sends a “check-in” packet in 10 second intervals. Once an initial check-in packet is received,
all StorView servers will know the existence of the other servers. If a server fails to send three check-in
packets, the other servers will mark that server as “missing.” This is indicated by a white “Server” icon
displayed on the Main screen under the “Other Servers” section.
When the server service that “owns” the monitored storage solution is down for any reason and three
check-in packets are not received, the monitoring will automatically be transferred to another StorView
server.
1.3 License Manager
StorView has two different licenses, a General Access License and the Feature License.
1.3.1 Access License Limits
The StorView General Access License which has different limits for the two RAID module versions of
StorView. The host-based version has Local Access and Global Access, and the embedded version has
Remote Access and Global Access. Refer to Section 4.2, ”Upgrading the Access License”, on page 27.
The Local Access is the default license of the host-based software. It provides the basic control,
management and monitoring of the locally attached storage solution.
The Remote Access is the default license included with the embedded version. It provides the same
functions as the Local Access license except it adds support for server failover and remote login. Remote
Access does not support features such as E-Mail notices, SYSLOG, and SNMP, however it does offer
an upgrade path to the Global Access license.
The Global Access license is offered for the above systems through a licensing program and provides
the capabilities of the Local Access features plus remote login, configuration, and monitoring, and it
provides alert notifications via E-Mail, SYSLOG and SNMP. With Global’s remote login and
management, the user can focus or log-in to a different storage solution that is not locally attached to the
host, allowing you to manage and monitor other solutions from just one location.

Introduction

1.3.2 Feature License
The Feature License enables the full use of the Snapshot feature incorporated into the RAID Controller
firmware. To access License Information, click the Controller icon on the Main screen and then the
LICENSE INFORMATION button at the bottom of the Controller Information window.
A limited free license is included with the system that allows for one (1) Overwrite Data Area (ODA) to be
created. Or you can purchase a full license which provides for up to eight (8) Overwrite Data Area (ODA)
to be created. With the limited free license, you can have up to four Snapshots for the single ODA. With
the maximum full license you can have up to twenty-four Snapshots for each of the eight ODAs. Each
ODA is paired to a physical Logical Drive allowing the user to create up to 4 or 24 Snapshots of their
logical drives, depending on the license.

A licensing upgrade path to the maximum full feature license is provided from the License Information
screen. To upgrade, you will need to provide your Configuration WWN and Serial Number for the specific
feature to obtain a license key. The serial number is found on the label affixed to the license certificate.
You will find the Configuration WWN displayed in the License Information window.
Below is an explanation of the fields of the licensing information window.
Once your license key is entered, click the Submit License Key button and the current licensing
information is displayed (Figure 1-4).
If you attempt to exceed the limited license you will receive a message. You will have the option to
upgrade the Limited Free license from that screen. Click the “UPGRADE LICENSE” button and enter a
new license key to enable the maximum license. Or you may upgrade any time by clicking the Controller
icon and then the LICENSE INFORMATION button. (Figure 1-5)

Drive Status Icon (continued)
• Rebuilding - Drive members of an array are in rebuild mode.
• Locate - Clicking the “arrow” icon next to the “specific array” in
the Arrays section will display an “arrow” icon on all the drive
members of that array in the front enclosure view.
• Critical - Drive(s) are members of a fault tolerant array and are
in a non-fault tolerant state.*
*NOTE : With RAID 6 disk arrays, the loss of a single drive does
not place the array in a non-fault tolerant state. The drive status
icon is the same for single or dual drive failures. To verify
whether the array is in a Non Fault Tolerant vs. Fault Tolerant
Warning state, identify the number of drive failures for the array.
Two drive failures will put the RAID 6 array in a non fault tolerant
state. Passing the mouse pointer over the status icon (yellow)
will display the array’s status, also in the Array Information
screen the status is displayed.
• Updating Firmware - This icon will appear when the subject
drive’s firmware is being updated.
• Failed Array Member - This icon will appear on all disk drives
that are members of an array that has failed. For example if you
remove a drive from a RAID 0 array or a drive in that array fails,
the remaining drive members will have this icon displayed
indicating that array has failed. If you accidentally remove the
wrong drive in a critical redundant array (RAID 5) instead of the
failed drive, that array will have failed and its member drives will
have this icon displayed. Re-inserting the drive that was
accidentally removed will put the drive members back to a critical
state in which the array is being rebuilt.
• Queued to Initialize - This icon is displayed on the drive
members whose array is to be initialized and is placed in a
queue for the process to be started and completed.
• Expanding - This icon is displayed on the drive members whose
array is expanding.
• Verifying - This icon is displayed on the drive members whose
array’s parity data is being verified.
• Unsupported - This icon is displayed when a drive does not
match the other drives for the array.
Enclosure Component Icons The following icons appear on the Main screen in the Enclosure
section. They provide an instant view of the operating status of the
