Drive Bay Locations
The SL8500 library features automatic detection of drives that are added or replaced.
There are four types of addressing schemes for drives:
■
Bay address (the physical location)
■
Internal address (assigned by the library firmware)
■
HLI-PRC (Host LMU Interface - panel, row, column address assigned by the host
software)
■
System addresses (assigned by the operating system)
Bay Address
The drive bay address is a two-digit number (01-64) representing the physical locations
into which drive tray assemblies are inserted. The bay number of a drive is strictly
internal to the library, defined by a drive’s position within a drive array. A drive is
automatically assigned a number from 1– 64 by the library controller after the drive is
installed and the library is re-initialized.
A decal on the rear of the Drive and Electronics Module depicts the bay numbers, as
shown in TABLE B-1 on page 125 . The bay numbers indicate the physical location of
drives. You have to be familiar with the bay numbers to locate a drive to perform a
manual mount (see “Manual Mode of Operation” on page 59 ).
