PowerVault ML6000 Maintenance Guide 57
There are some configuration settings to take into account when adding a 9U Expansion Module to an
existing library.
• All COD licenses remain the same. If the current license key does not cover the expanded capacity,
you will need a new license key to use the newly available slots.
• Partition, I/E station slot, and cleaning slot assignments do not change; however, unassigned slots
may change location.
• Modifying partitions can cause the storage slots to be scattered throughout the library.
• I/E station slots in the new module(s) are assigned as data storage slots. You can reconfigure these
slots as I/E station slots after the 9U Expansion Module has been added to the library.
A library can use up to four 9U Expansion Modules to a maximum height of 41U.
There are no restrictions on where the control module can be installed in the library configuration. However,
the recommended placement of the control module for library configurations up to 32U is on top of all
installed 9U expansion modules. The recommended placement of the control module for 41U library
configurations is on top of three 9U expansion modules and below the top 9U expansion module.
When adding additional 9U expansion modules to an existing library configuration, the recommended
placement of the new 9U expansion module is at the bottom of the existing library configuration (except for
the 41U library configurations, where recommended placement is on top). Installing the new 9U expansion
module at the bottom of the existing library configuration will logically assign slot numbering within the
library.
The maximum number of 9U Expansion Modules supported in a library
depends on the level of firmware the library is running. The latest firmware
must be installed on the library if you are upgrading from a 5U or 14U
configuration to a larger configuration. The latest firmware can be found on the
Dell Support Website. For the Dell Support Website address, see Contacting
Dell. See the library Users Guide for more information.
