`
`Chapter 1. Quick start
`
`Prerequisites
`
`Getting started
`
`This guide assumes that the hardware has been set up successfully using the IBM
`TotalStorage IP Storage 200i Installation Guide and you have set the initial IP
`address.
`
`The IBM TotalStorage IP Storage 200i requires a web browser to access the
`Administrative Console. The supported web browsers are the Microsoft® Internet
`Explorer 5.x (and later) and Netscape 4.5 (and later) running on Windows 98,
`Windows Millennium, Windows NT, and Windows 2000. An Internet connection is
`recommended.
`
`Note: The IBM IP Storage requires a direct connection from the browser, not
`through a proxy server. If a proxy server is used for the Internet, the IBM IP
`Storage must be excluded.
`
`The Administrative Console requires the following plug-ins, which are available
`online at www.sun.com:
`v Java™ Swing 2
`v Sun Java Plug-in 1.3
`
`Note: The Sun Java Plug-in 1.3 is a product of Sun Microsystems, Inc. IBM does
`not distribute, support or maintain the Sun Java Plug-in 1.3 and your use of
`this product is subject to license terms and conditions imposed by Sun
`Microsystems, Inc. Contact Sun Microsystems, Inc. directly if you have any
`questions about this product.
`
`Code updates are installed from a local FTP server. This FTP server must support
`anonymous FTP.
`
`The IBM IP Storage is configured and managed through the Web-based
`Administrative Console. You can access this console through a Web browser, either
`Netscape or Internet Explorer. An Internet connection from the Administrative
`Console to the Internet is recommended. If you have an Internet connection, the
`browser must connect to the Internet directly rather than through a proxy server.
`Because the appliance is headless, configuration must be completed from another
`machine, known as the management workstation.
`
`Before the IBM IP Storage can be fully functional as an iSCSI server, you must
`complete a set of required configuration tasks using the Administrative Console.
`Refer to the initial configuration section in the IBM TotalStorage IP Storage 200i
`Installation Guide for instructions.

`
`Accessing the Administrative Console
`You can access the Administrative Console from any supported Web browser by
`performing the following steps:
`1. Point your browser to the appliance at:
`
`http://hostname:1959/IBM200i
`
`where hostname is the host name or IP address of the appliance.
`2. Type your user ID in the User Name field. The default user ID is “administrator.”
`Note that the user ID is case sensitive.
`3. Type your password in the Password field. The default password for the
`administrator user ID is “password.” Note that the password is case sensitive.
`4. Click OK.
`
`Introducing the Administrative Console
`The Administrative Console is a Web-based management tool that aids you in
`setting up and reconfiguring an IBM IP Storage appliance. The Administrative
`Console is divided into three frames: the Toolbar, Navigator, and Workspace.
`
`Toolbar
`
`The toolbar is located at the top of the page. It contains the following
`buttons:
`
`Logoff
`
`Logs you off of the Administrative Console.
`
`Help Displays help for elements on the current page.
`
`Navigator
`The Navigator is located on the left side of the page. It contains a
`navigation tree that allows you to make your way through the configuration
`pages. This tree is made up of the following items:
`
`Network
`Enables you to set IP addresses and configure the domain and
`SNMP.
`
`Storage
`Enables you to manage logical drives, virtual disks, and user
`access.
`
`System
`
`Enables you to identify the appliance, set the date and time, create
`administrators, manage code and configuration files, control locks
`on the Administrative Console, and reset the appliance.
`
`Logs Enables you to view various log reports.
`
`Workspace
`Displays the frames that require input from the administrator. Although
`some frames include buttons that are specific to the task you are
`performing, these main buttons are included on each frame within the
`workspace:
`
`Apply Activates the changes that you want to make.

`
`Chapter 2. System configuration
`
`This chapter describes how to configure the IBM IP Storage.
`
`Administration
`
`You can define and manage administrators using the Administrative Console. The
`edit and browse modes are especially useful when you have multiple administrators
`accessing the system and making changes. As the names indicate, browse mode
`only allows viewing, while the edit mode enables the user to make changes in the
`system. You can initiate the edit mode by taking control of any system locks. See
`“Control locks” for additional information about locks.
`
`Viewing the list of administrators
`To view the list of administrators that are defined in the system using the
`Administrative Console, click System —򐂰 Administrators.
`
`Adding an administrator
`To add an administrator using the Administrative Console:
`1. Click System —򐂰 Administrators.
`2. Click Add to add a new administrator.
`3. Type the user name of the administrator in the Administrator field.
`4. Type the password in the Password field.
`5. Type the password again in the Verify password field.
`6. Click Apply.
`
`Changing an administrator’s password
`To change an administrator’s password using the Administrative Console:
`1. Click System —򐂰 Administrators.
`2. Select the radio button to the left of the administrator’s user ID.
`3. Click Edit to edit the administrator configuration.
`4. Type the new password in the Password field.
`5. Type the new password again in the Confirm password field.
`6. Click Apply.
`
`Removing an administrator
`To remove an administrator using the Administrative Console:
`1. Click System —򐂰 Administrators.
`2. Select the radio button to the left of the administrator’s user ID.
`3. Click Remove to delete the administrator.
`
`Control locks
`
`Administrators can lock access to certain system configuration elements so that
`only one person is assigned editing ability to those specific elements. After one
`administrator takes control of locks, others only see the system in browse mode
`and are unable to make changes (that is, no action buttons will appear). Other
`administrators can make changes by taking control themselves.
`

`
`LENOVO ET AL. EXHIBIT 1007
`
`Page 5
`
`

`
`The person who takes control of the system does not have to release it. Any other
`administrator with system access can take control and lock the system out to
`others. Locks simply enable multiple administrators to better coordinate system
`configuration changes.
`
`Notes:
`1. Every time you close the browser and reopen, you lose control of locks. To
`make additional system configuration changes, you will need to take control of
`locks each time you open the browser.
`2. Before taking control of locks, be sure that no other administrator has changes
`pending. Taking control before these changes have been activated will result in
`the changes not taking effect. Other administrators are not warned when control
`of is taken.
`If you have control of certain elements and you close your browser without first
`logging off, you still have control of those elements.
`
`3.
`
`To control locks on the Administrative Console:
`1. Click System —򐂰 Control locks.
`2. Click Take Control.
`
`System settings
`
`Viewing the model and serial number
`To view the model and serial number of the IBM IP Storage using the Administrative
`Console, click System—򐂰 Settings.
`
`Setting the date and time
`To set the date and time using the Administrative Console:
`1. Click System —򐂰 Date and time to display the current date and time settings.
`2. Type or select the month in the Month field.
`3. Type or select the day in the Day field.
`4. Type the year in the Year field.
`5. Type or select the hour in the Hours field.
`6. Type the minutes in the Minutes field.
`7. Type the seconds in the Seconds field.
`8. Click Apply.
`
`Configuring network settings
`To configure the network settings, including the domain, gateway, and domain name
`server (DNS), using the Administrative Console:
`1. Click Network —򐂰 Settings.
`2. Type the IP address of each DNS server in the Name Server x fields. You can
`define up to three DNS servers.
`3. Type the domain name in the Domain field.
`4. Type the IP address of the gateway in the Gateway field.
`5. Select the Rip listen enabled check box to enable RIP or clear the check box
`to disable it.
`6. Click Apply.
`7. Restart the appliance (see “Restarting the appliance” on page 7).

`

`
`Restarting the appliance
`To shut down and restart the appliance using the Administrative Console:
`1. Click System —򐂰 Reset.
`2. Click Restart.
`3. Click OK.
`4. Wait several minutes.
`5. Click Reconnect to reconnect to the Administrative Console.
`
`Note: If you receive an error message, you attempted to reconnect to the
`Administrative Console before the appliance finished restarting. Close the
`browser, and wait a few more minutes before restarting the browser and
`connecting to the Administrative Console.
`
`Shutting down the appliance
`To shut down and restart the appliance using the Administrative Console:
`1. Click System —򐂰 Reset.
`2. Click Shut down.
`3. Click OK.
`
`Note: When you shut down the appliance, you lose your connection to the
`Administrative Console through your Web browser.
`
`RAID
`
`The redundant array of independent disks (RAID) configuration allows you to
`dynamically manage the logical drives. A logical drive is a unit of virtual storage that
`is made available to the network. Logical drives consist of multiple physical disks
`combined using RAID level 0, 1, 1E, 5 or 5E technology. A physical disk cannot
`hold any user data unless it belongs to a logical drive.
`
`The IBM IP Storage Model 200 supports up to 48 physical disks in a fully
`configured system. The minimum number of logical drives is one, and the maximum
`number is eight. (If any logical drive has a RAID configuration of 5E, then the
`maximum number of logical drives is seven.) Each logical drive can have a
`maximum of 16 physical disks, although a maximum of eight is recommended.
`
`The Model 100 supports up to 6 physical disks.
`
`The following types of disks are shown:
`
`Physical disks
`A disk that has not been assigned as a hot-spare, standby hot-spare, or to
`a logical drive.
`
`Hot-spare disks
`A disk that is not part of a logical drive but can be mapped to a logical drive
`if one of the logical drive’s disks goes offline. The logical drive runs in a
`degraded, or exposed, condition until all data on the new disk is
`regenerated.
`
`A hot-spare disk can also be defined as a standby hot-spare disk. A
`standby hot-spare can be mapped to a logical drive if no suitable hot-spare
`disk is available.
`
`Chapter 2. System configuration 7
`
`LENOVO ET AL. EXHIBIT 1007
`
`Page 7
`
`

`
`Except for RAID 0, a single disk failure can be recovered by replacing the
`failed disk. No configuration changes are necessary. If a hot-spare disk is
`available, it is automatically used to replace the failed disk. Data is
`automatically rebuilt for the hot-spare disk. If a hot-spare disk is not
`available, data is rebuilt when the failed disk is replaced with a new disk.
`
`Logical drives
`A disk that has been assigned to a logical drive. These disks are displayed
`under the logical drive in the RAID Configuration tree.
`
`The RAID panel is divided into two subpanels: the RAID Configuration tree
`containing a graphical representation of the RAID controller, logical drives, and
`physical disks in the system and the Properties table that shows the information
`about the selected component.
`
`Refreshing the configuration
`The RAID configuration panel is refreshed each time the panel is opened and after
`each task. It is not automatically updated after a given period of time. It is
`recommended that you refresh this panel after an extended period of time.
`
`To refresh the RAID configuration displayed on the Administrative Console:
`1. Click Storage —򐂰 RAID.
`
`Note: Displaying this pane for the first time may take several minutes,
`depending on your network-connection speed.
`2. Click Controller 1 to highlight it.
`3. Right-click Controller 1.
`4. Click Refresh the configuration from the pop-up menu.
`
`Scanning for physical disks
`When you add or remove disks, you must update the RAID configuration by
`scanning the appliance for current physical disks.
`
`Note: Physical disks that are part of a logical drive must not be disrupted by
`removal or replacement. Adding, removing, and replacing physical disks
`must be restricted to free disks.
`
`To scan the appliance for new and removed disks in the Ready state using the
`Administrative Console:
`1. Click Storage —򐂰 RAID.
`
`Note: Displaying this pane for the first time may take several minutes,
`depending on your network-connection speed.
`2. Click Controller 1 to highlight it.
`3. Right-click Controller 1.
`4. Click Scan for ready disks from the pop-up menu.
`5. Click Scan to scan for disks. When scanning is complete, the dialog box reports
`the number of new and removed disks found.
`6. Click Close. The dialog box closes, and any new disks are moved to the
`Physical disks folder in the RAID Configuration tree.

`
`

`
`Creating a logical drive
`You can create a maximum of eight logical drives on one appliance.
`
`To create a logical drive using the Administrative Console:
`1. Click Storage —򐂰 RAID.
`
`Note: Displaying this pane for the first time may take several minutes,
`depending on your network-connection speed.
`2. Click Controller 1 to highlight it.
`3. Right-click Controller 1.
`4. Click Add logical drive from the pop-up menu.
`5. Select the RAID level from the RAID level drop-down list. You can choose one
`of the following levels:
`
`RAID 0
`
`RAID 1
`
`Stripes the data across all physical disks in the logical drive. This level
`offers substantial speed enhancements, but provides no data
`redundancy. It provides the largest capacity of the RAID levels because
`no room is taken for redundant data or data-parity storage.
`
`RAID level 0 requires a minimum of one physical disk, and supports a
`maximum of 16 physical disks. If you have a logical drive that contains
`only one physical disk, you can assign only RAID level 0 to that logical
`drive.
`
`This level is recommended for data stores primarily used for sequential
`data operations where data stores require no redundancy (for example,
`program-file repositories and daily backups).
`
`Provides data redundancy using disk mirroring. The first half of a stripe
`is the original data; the second half of a stripe is a mirror (copy) of the
`data that is written to another disk in the RAID level 1 logical drive. If
`one physical disk fails, the ServeRAID™ controller switches read and
`write requests to the remaining functional disk in the RAID level 1
`logical drive.
`
`RAID level 1 requires two physical disks. If you have three or more
`physical disks in the logical drive, you cannot select RAID level 1. You
`can, however, select RAID level 1 Enhanced (RAID level 1E).
`
`This level is recommended for high-performance and write-intensive
`random-access applications (for example, database applications).
`
`RAID 1E
`Combines mirroring with data striping. This RAID level stripes data and
`copies the data across all of the disks in the logical drive. If one of the
`physical disks fails, the ServeRAID controller switches read and write
`requests to the remaining functional drives in the RAID level 1E logical
`drive.
`
`RAID level 1E requires a minimum of three physical disks and supports
`a maximum of 16.
`
`RAID 5
`
`Stripes data and parity across all physical disks in the logical drive. The
`capacity of the logical drive is reduced by one physical disk, for
`data-parity storage.
`
`Chapter 2. System configuration 9
`
`LENOVO ET AL. EXHIBIT 1007
`
`Page 9
`
`

`
`RAID level 5 requires a minimum of three physical disks and supports a
`maximum of 16.
`
`RAID 5E
`Is the same as RAID level 5 with a built-in hot-spare disk. Like RAID
`level 5, RAID level 5E stripes data and parity across all physical disks in
`the logical drive. The capacity of the logical drive is reduced by two
`physical disks: one for data-parity storage and one for hot-spare. This
`RAID level is more efficient than RAID level 5 (three physical disks) with
`an idle hot-spare. This spare cannot be shared with the other logical
`drives.
`
`RAID level 5 requires a minimum of four physical disks and supports a
`maximum of 16. You can have a maximum of seven RAID level 5E
`logical drives.
`6. Select the write-cache method from the Write cache method drop-down list. You
`can choose one of the following values:
`v write back
`v write through
`7. Add physical disks to the logical drive:
`a. Select one or more physical disks that you want to add to the logical drive
`from the Available disks list.
`b. Click >>> to add the selected disks to the Selected Disks list.
`
`The size of the logical drive displayed below the Selected Disks list is
`calculated each time you move a disk from either list.
`
`Note: Depending on your choice of RAID levels, there might be restrictions on
`the number of physical disks that can be used to create the logical drive.
`The Administrative Console warns you of invalid assignments. You can
`assign a maximum of 16 physical disks to one logical drive.
`8. Remove a physical disk from the selected list.
`a. Select one or more physical disks you want to remove from the Selected
`Disks list.
`b. Click <<< to move the selected disks back to the Available disks list.
`9. Click Add. The new logical drive appears in the RAID Configuration tree with
`the assigned disks nested beneath it.
`
`Removing a logical drive
`
`Note: If virtual logical units (VLUNs) are assigned on the selected logical drive, you
`are
