Lock Element Addressing
Lock Element Addressing should be used on a CLM library with 3 or more cabinets. When enabled,
Lock Element Addressing ensures that if a secondary cabinet goes off-line, locations and counts of
drives, hosts, and all other elements in the remaining cabinets stay the same. If a cabinet fails when this
feature is disabled, these elements will likely change.
To enable or disable Lock Element Addressing:
1. From the OCP of the primary cabinet, select Menu, then Setup.
2. From the Setup screen, select Lock Element Addressing.
3. Use the Up and Down arrows to highlight Enabled or Disabled, the press Select.
Disable Lock Element Addressing in order to change locked elements such as load ports, number of
drives, or number of cabinets.
Library storage locations and slot numbering
The HP StorageWorks ESL E-Series standalone tape library is an automated tape storage and retrieval
library that may consist of up to 24 tape drives and up to 718 Ultrium tape cartridges, or 636 SDLT tape
cartridges, or a combination of Ultrium and SDLT tape cartridges in a mixed-media system.
NOTE:
CLM libraries have different storage capacities and requirements depending on how many cabinets are
in the library, among other considerations. Due to the number of variations possible, slot numbering
for CLM libraries is not provided. The panel and general slot information presented here does apply
to each cabinet within a CLM library.
The library stores tape cartridges in the following locations:
• Left panels
• Right panels
• Back panels
