Chapter 2. Planning for adding file modules
Plan for bandwidth, Fibre Channel ports, and system requirements when you add
file modules to an existing Storwize V7000 system to make a Storwize V7000
Unified system.
System requirements for adding file modules
You must define your requirements prior to, and during, the adding of file
modules.
Purpose
To define and understand the requirements associated with adding file modules,
including best practices.
Access
v
You must have access to the:
– Storwize V7000 Management GUI and command-line interface (CLI), to help
with planning, preparing, and adding the file modules
– Physical access to the Storwize V7000 system, and the associated network
switches
– Fibre channel hosts that may need their multi-pathing driver restarted or
rescanned (to find added or removed paths)
– Fibre channel storage systems providing MDisk
– Fibre channel switches that require zoning changes to provide any new paths,
and for removing the paths to ports 1 and 2 of the control enclosure.
Storwize V7000 and file module software levels
v
File modules are loaded with IBM Storwize V7000 Unified software at IBM
Manufacturing.
v
File modules with any level of IBM Storwize V7000 Unified software can be
added to an IBM Storwize V7000 at any level of software after 6.3.0.0. However,
file modules have only been tested with the IBM Storwize V7000 software levels
that are included in the Storwize V7000 Unified software update package.
Tip:
From the support page (www.ibm.com/storage/support/storwize/v7000/
unified), search for the document:
Concurrent Compatibility and Code Cross
Reference for Storwize V7000 Unified
. Then, refer to the Software
Cross-Reference table to see the version of Storwize V7000 software included in
each of the Storwize V7000 Unified software update packages.
After the file modules have been added to the system, you must update the
Storwize V7000 Unified software as soon as you have completed the initial
configuration of the system, and can access the update software panel in the
management GUI. When you update the Storwize V7000 Unified software, it will
automatically update the Storwize V7000 software to the level which has been
tested with that level of the Storwize V7000 Unified software.
If the Storwize V7000 software is updated as part of the initial setup of the file
modules, there will be some rebooting of the node canisters, and failing over of the
