Gathering Configuration Information for Virtual Libraries

Pathlight VX enables virtual libraries to be created that emulate physical (tape) libraries and to enable the

virtual libraries to be visible to one or more FC Hosts in the customer environment. To successfully create

and configure virtual libraries on Pathlight VX, certain configuration information needs to be gathered.

In Table 21

on page 30, for each virtual library to be created on the Pathlight VX, record the type of physical

library it emulates, the virtual library name, the type of physical library it emulates, the number of slots

available in the physical library it emulates, the number of drives available, the system name of each FC

blade (on the SNC hosting the backup application), and whether extended bar codes will be used.

a. Up to 6 virtual libraries can be created in Pathlight VX without engaging the ADIC Technical Assistance Center (ATAC). To

create more than 6 virtual libraries, contact ATAC. Refer to Getting More Information or Help

on page 3.

b. The maximum number of virtual drives spans the number of virtual libraries created. For example, a system with 40 virtual

drives and 6 virtual libraries must span the 40 drives across all 6 libraries.

c. If the Disk Extension (Storage Policies) Advanced Feature will be enabled on the Pathlight VX, tape capacity will be

significantly increased. For more information, contact ATAC. Refer to Getting More Information or Help

on page 3.

CAUTION

Switching devices across FC blades changes the device path to the virtual

device and impacts the Host’s view of devices from the SAN network. Making

these changes requires reconfiguration of both the FC Host(s) and the

backup application.
