HLI-PRC Addressing Scheme

Library Complex HLI Numbering

In a library complex, the LSM number increases sequentially with each additional
library. The LSM numbering continues with the following pattern for up to ten
libraries:
Library 1: LSM 0 to 3
■
Library 2: LSM 4 to 7
■
Library 3: LSM 8 to 11
■
When adding an additional library to a complex, you should add libraries from right
to left (viewed from the CAP-side of the library). Expanding left to right re-numbers
the LSMs requiring you to reconfigure hosts.

Drive HLI-PRC Addressing

For drives, the panel value is always equal to 1, the column value is always equal to 0,
and the row value is between 0 and 15.
