Introduction
The HP StorageWorks ESL9000 Series pass-through mechanism (PTM) enables
the transfer of a single tape cartridge between two HP StorageWorks ESL9000
Series Tape Libraries. Any combination of ESL9000 Series libraries can be
connected as long as the total number of elements does not exceed 2500, or 5
library cabinets. This includes the robotics/picker (medium transport element),
drives (data transfer elements), slots (storage elements), and load port
(import/export element).
Caution: If any library is to utilize Multi-Unit (MUSL) functionality, all libraries
must be running firmware 3.10 or later. In order to utilize MUSL functionality,
all libraries must have the proper backplanes (PN 6310520-04 or newer),
proper robotic controller boards (PN 6221710-21 or newer) and QSPI cables.
All libraries running firmware 1.30 or earlier that upgrade to 3.10 or later that
will utilize MUSL functionality with another library must reinitialize NV RAM
and use the new memory module (PN 6312910-06). To support the new
memory module, boot block version 2.01 must be installed. If a library is
configured in Single mode, then there is no need to upgrade the boot block or
memory module, but the NV RAM must still be reinitialized.
Ensure you understand the capabilities of your application software before
enabling autoclean. If the tape drive autoclean feature is to be supported, be
sure that at least one cleaning tape exists in each library that will support
autocleaning.
Before connecting any libraries together, check with your software application
vendor to ensure that the application will work with scaled libraries and the
higher element count.
