Pathlight VX Site Preparation Guide 49

Use Table 34 to record the model and firmware information about the aggregation device.

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.

• If the device is zoned, the zone must allow access between Pathlight VX I/O blades, the physical

library controller, and any of the respective drive resources.

• Physical drives and libraries dedicated to Pathlight VX can be attached only to internal switch ports

12, 13, 14 (not used as ISLs to aggregation switches).

• Aggregation devices can connect only to the FCB1-FC6 and FCB2-FC6 ports.

• Both Pathlight VX I/O blades and the Pathlight VX MS HBA must be mapped from the physical

library to have access to all physical library controllers and drive LUNs.

• When mapping multiple partitions from a physical library to each Pathlight VX FCB and the MS

HBA, the strategy must always map the drive members after each respective partition to ensure

Pathlight VX can properly associate the correct drive members to the correct physical library.

• When Disk Extension Tape (DET) policy management is enabled, best practice is to dedicate a

partition for DET media. This partition should not have more than four drives.

CAUTION

The aggregation device must be dedicated to the Pathlight VX; it

cannot be used as an aggregation device for the broader fabric

domain, even when the device is zoned. Any non-compliance with

this guideline could result in the loss of data.

CAUTION

If the components of the Pathlight VX cannot communicate as

described in this guideline, the Pathlight VX will not function.

CAUTION

The aggregation device must not be connected to a Pathlight VX

internal switch.

Note

When you configure port 6 on the FC blade to communicate with an

aggregation device, the Connection Options field must be set to Point to

Point. Refer to "Configuring FC Port Parameters" in Pathlight VX

Installation Guide.

Note

Consult "Configuring a Physical Library for a Pathlight VX" in Pathlight VX

Installation Guide for cabling information.
