paths from hosts to volumes. You may wish to wait until a time of low system
work load before proceeding with the initial setup of the file modules. Consider
updating the Storwize V7000 to the latest software level that has been tested with
the latest Storwize V7000 Unified software before you begin to add the file
modules.
Important:
Because the Storwize V7000 software can not be downgraded, do not
update the Storwize V7000 to the latest level before you add the file modules,
unless that level has been tested with file modules.
Important:
Install and run the
IBM2076_INSTALL_upgradechecker_<version>
utility
before attempting to apply an update to the Storwize V7000 software. Access this
utility from the update wizard, in the management GUI.
The
up2nas
update to network attached storage (NAS) checker utility, verifies that
the current Storwize V7000 software level is older than, or the same as, the level
included in the latest Storwize V7000 Unified software update package. This utility
is also known as the Storwize V7000 to Storwize V7000 Unified Conversion Utility.
1.
Download the latest
up2nas
installable package from www.ibm.com/storage/
support/storwize/v7000/unified; then upload it to the
/home/admin/upgrade
folder on Storwize V7000.
2.
Install the
up2nas
software package. For example:
applysoftware -file IBM2076_INSTALL_up2nas_<version>
.
3.
Run
up2nas
on the Storwize V7000 CLI.
Storwize V7000 Unified Fibre Channel ports
If Fibre Channel port 1 or port 2 on each node canister in the control enclosure is
connected to a fibre channel switch, then plan how to add more fiber channel
paths if needed. This is so that the switch can be disconnected from port 1 and
port 2 to allow connection of the file modules; it should be possible to do this
without requiring an outage.
1 Gbps Ethernet ports and IP address
v
If you only have one of the 1 Gbps Ethernet ports on each node canister in each
Storwize V7000 control enclosure connected to a 1 Gbps Ethernet switch then
you can choose to connect the second port to the switch to allow for a
redundant path from the active management node on a file module to ssh CLI
commands to the Storwize V7000.
v
One or two ports on the same 1 Gbps Ethernet switch to which the control
enclosure is connected to are needed for each file module.
v
One or two IP address for each file module are needed in the same IPv4 subnet
as the system IP address of the Storwize V7000 system.
v
A management IP address to access the Storwize V7000 Unified management
GUI and command-line interface (CLI) is needed in the same IPv4 subnet as the
Storwize V7000 system IP address. The Storwize V7000 Unified management
GUI will be provided by whichever file module takes the active management
node role. If the active management node becomes unavailable, then the other
file module will take over the active management node role and the
management IP addresses, so that administrative users can access the
management GUI and CLI again.
v
The Storwize V7000 Unified system utilizes the other services it needs via the
management IP address. For example, the authentication server, Network Time
Protocol (NTP) server and email server.
