Planning to Install and Configure Pathlight VX This chapter contains information-gathering tasks related to installing and configuring the Pathlight VX at the customer site. The Pre-Sales Engineer and, in some cases, the Key Account Program Manager (KAPM), should use these tables to document the installation information gathered during the design phase with the customer. The information can then be available to the resources assigned to the Installation tasks so that the deployment is executed as designed.
Installation, Configuration, and Integration Requirements Pathlight VX installation involves two phases: hardware installation and configuration, and integration of the Pathlight VX in the customer environment. This section provides information about Pathlight VX configurations, and specifies requirements that must be met to successfully install, configure, and integrate the Pathlight VX in the customer’s environment.
Table 20 Virtual Capacity - Libraries, Drives, and Tapes (Continued) Maximum Number of Virtual Librariesa Maximum Number of Virtual Drivesb Maximum Number of LTO-1 Virtual Tapesc Maximum Number of LTO-2 Virtual Tapesc Maximum Number of LTO-3 Virtual Tapesc 18.2 TB 6 40 182 91 45 24.1 TB 6 40 241 120 60 30.0 TB 6 40 300 150 75 35.9 TB 6 40 359 179 89 41.8 TB 6 40 418 209 104 47.7 TB 6 40 477 238 119 53.6 TB 6 40 536 268 134 24.4 TB 6 40 244 122 61 30.
Valid values for the Physical Library Type Being Emulated are: Pathlight VX, Scalar 100, Scalar 1000, Scalar i500, Scalar i2000, and Scalar 10K. Because the customer’s backup application views each virtual library as a physical library, estimate the Number of Slots value by making sure there are no slot limitations and specifying a large number of slots (depending upon the customer’s backup cycle needs and the licensing on the customer’s backup application).
Gathering Configuration Information for FC Port Parameters Once Pathlight VX is attached to the host, the FC port settings are automatically detected. At install, log into Service > Port Configuration > Configure and update Table 22 to record the settings used to define the FC port parameters of the Pathlight VX. You can configure FC ports 1, 3, and 6 on each blade.
Gathering Configuration Information for FC Host Parameters In Table 23, record the settings used to define the FC Host parameters for each Virtual Library created in the Pathlight VX. • Virtual Library Name is the virtual library being mapped to the FC Host. • For the FC Blade for Host column, specify the FC blade that is mapped to the particular FC Host. • For a Pathlight VX-450 or a Pathlight VX-650 (Entry-Level Configuration), the valid value is: FC Blade 1.
Table 23 Configuration Information for FC Host Parameters (Continued) Virtual Library Name FC Blade Host Name Pathlight VX Site Preparation Guide Type WWN Configure LUN Mapping Device LUN 33
Optionally, you can also use Table 24 on page 35 and Table 25 on page 36 to define which hosts will be configured to what virtual device LUNs and their LUN instances. You need to duplicate the information in these tables for every virtual library and its drives that are created. In Table 24 and Table 25, virtual devices are presented to each blade in an alternatively distributed, sequential order by default.

When integrating an FC device to the customer SAN, the SE must document the customer’s SAN configuration using the information provided in Table 26. The SE should then review the completed information with the ADIC Pathlight VX Compatibility Guide on CS Web, and anticipate and resolve any compatibility issues. Please contact Service Program Management for more information. • • Host Parameters: • For the Name parameter, valid values are: any alphanumeric combination allowed by the FC Host.
Gathering Configuration Information for Virtual and Physical Media and gather corresponding virtual and physical media information for libraries. The information in these two tables affects sizing, and should be defined in Pre-Sales design and discussed in the Pre-Installation call. If one or more physical (tape) libraries will be connected to the Pathlight VX, then the barcode label (volser) of each physical tape volume must match the barcode label (volser) of its corresponding virtual tape (volume).

Pathlight VX Advanced Features Pathlight VX offers the following Advanced Features that can be enabled through either the Pathlight VX Service Interface or the Pathlight VX User Interface. • Archive enables you to remove physical application media from a library while retaining their virtual counterparts in a defined operation window. • Early Tape Creation enables exports of virtual media to complete faster by expediting the creation of their physical counterparts in a defined operation window.
Preparing for Early Tape Creation Settings Table 30 assists in gathering information for Early Tape Creation (ETC). • Maximum number of Physical Drives to use, the maximum value is equal to 1 less than the total number of physical drives. • The valid values for the Media Percentage parameter are percentages from 75 to 99. Specify the percentage at which ETC initiates for the associated media.
• The Minutes Before Copy parameter refers to the number of minutes that virtual media must be idle before the Pathlight VX backup application is done using it. For example, if media is used for multiple backup jobs, but it might be unloaded between jobs, then this parameter should be set to 0 minutes. If the media is usually filled during a single job, or is only used for a single job, then this parameter should be set to a low value.
Preparing for Physical Exports and Virtual Imports As part of system tuning, specify the maximum number of physical exports and virtual imports. Valid values are 1 to 1 less than the total physical drives in the attached physical libraries. You specify this number through the Service login only. The default value is half the number of physical drives.
Planning to Configure Physical Libraries and Remotely Manage the Pathlight VX This section specifies information needed to configure one or more physical (tape) libraries attached to the Pathlight VX, determine when an aggregation device is required, and remotely manage the Pathlight VX. This information must be gathered before the Pathlight VX is installed. The Systems Engineer (SE) and the Key Account Program Manager (KAPM) should gather the specified information and assign tasks to installers.
Pathlight VX Connectivity to an External Aggregation Device Up to four physical (tape) libraries can be connected to the Pathlight VX. Depending on the library type and number of libraries attached to the Pathlight VX, the customer may need to provide an external aggregation device so the required number of port connections are available. The aggregation device must be an FC switch. ADIC recommends that a Brocade FC switch be used as an aggregation device.
Figure 2 Aggregation Decision Path: Pathlight VX-450 / Pathlight VX-650 (Entry-Level Configuration) Configurations with one blade that has one FC port for physical libraries.
Figure 4 Aggregation Device Path: Pathlight VX-650 (High-Performance Configuration) Configurations that use an internal switch with three FC ports for physical libraries. A Can all device LUNs in all physical libraries be accessed on 3 or fewer FC ports on the Pathlight VX internal switch? yes Aggregation device not required no Aggregation device required Finish If the customer will use an external aggregation device with the Pathlight VX, then record information about the device in Table 33.
Use Table 34 to record the model and firmware information about the aggregation device. Table 34 Aggregation Device Model Information Description Model Information Aggregation Device Model: Aggregation Device Manufacturer: Aggregation Device Firmware: Follow these guidelines when connecting an aggregation device: • The aggregation device must be dedicated exclusively to a Pathlight VX physical library. The aggregation device cannot be used for Inter-Switch Link (ISL) connections to customer SANs.
Pathlight VX Connectivity to Physical Libraries CAUTION Physical libraries must be operating in native mode in order to function properly with Pathlight VX. For example, a Scalar i2000 cannot be set up to emulate a Scalar 100; it must be operating as a Scalar i2000.

Pathlight VX and Physical Library Remote Management The Pathlight VX’s connection to the customer network enables the system to be remotely configured, managed, and monitored. If Pathlight VX will be attached to one or more physical (tape) libraries, then the IP address and network information for the library and library components must be recorded (in Table 40) to be able to perform operations on the libraries.
Use Table 43 to prepare to configure the partitions on the physical library. When attaching physical libraries on Pathlight VX that is running Policy Management, the best practice is that DET should have a separate dedicated partition. Note • For the Number of Drives values, the best practice is to specify a maximum of 4 drives for DET. • For the Media Type Checking and Return Identifier values, note that the settings can vary from site to site and across firmware versions.
