be using the system IP address" on page 202 for how to check for a duplicate IP
address on your network and how to change the control enclosure IP address if
necessary.
If the file modules can no longer ssh CLI commands to the storage system CLI
then the first thing to do is make sure that the management IP addresses are
correctly set. You may find the GUI works very slowly in this case, so access the
CLI by using ssh to the log on to the management IP address as admin (default
password admin).
For example:
Use the lsnwmgt CLI command to show you the IP addresses used by the file
modules for management. For example:
Use the lsstoragesystem CLI command to show you the IP address that the active
management node, running on one of the file modules, will use to ssh commands
to the storage system CLI. For example:
Check that these 5 or 6 IP addresses and sub net mask are as expected. Attempt
the lssystemip CLI command which will probably fail when the active
management node running on a file module attempts to ssh it to the storage
system CLI running on a control enclosure. For example:
However, if this CLI command now works then the original problem with ssh to
the storage system CLI may have gone away. Otherwise, use ping to check the
network connections between the storage system and the file modules. It does not
work from the management CLI but it should work from the storage system CLI.
From an external computer ssh as superuser to the primary IP given by the
lsstoragesytem CLI. The IP that the active management node will be trying to ssh
commands to the storage system CLI. For example (default password is passw0rd):
If you can not ssh to the storage system primary IP or secondary IP (that was
given by the lsstoragesystem CLI command) then follow the procedure to use the
USB flash drive to discover the state and settings of the Storwize V7000. Make sure
that there is no satask.txt file on the USB flash drive before you plug it into the
control enclosure.
