Sun Microsystems SL8500 manual System Address, Manually Locating a Drive Bay

System Address

The tape drives are associated with and belong to each LSM (numbered 0-3). Each LSM is assigned 16 drives (0-15). Panel 1 is designated as the drive panel. To mount a cartridge tape in a different LSM, the cartridge must go through an internal pass-thru port (the elevator) to the drive.

System Address

The operating system also assigns system addresses to drives. Because Fibre Channel is the operating mode for drives within a SL8500 library, you can minimize a network re- configuration resulting from the replacement of a defective drive by enabling dynamic World Wide Name (dWWN) through the library configuration process. See “Dynamic World Wide Name” on page 29. A system address, once assigned, is automatically re- assigned when a drive is replaced.

Manually Locating a Drive Bay

If you need to perform a manual mount to a drive, the Library Console provides mapping of the hardware, firmware, and software mapping for all the drives attached to a library.
