Problem: Unable To Change The System Ip Address Because You Cannot Access The Cli - IBM Storwize V7000 Unified Problem Determination Manual

command, then it is necessary to update the record. The chstoragesystem
command changes the file module record of the control enclosure system IP. Here
is an example:
>[kd01ghf.ibm]$ chstoragesystem --ip1 9.71.18.136 --ip2 9.71.18.136
EFSSG1000I The command completed successfully.
Verify that communication from the file module to the control enclosure is now
possible by running the lssystem command on the Storwize V7000 Unified
management CLI:
>ssh admin@<managment IP address>
[kd01ghf.ibm]$ lssystemip
Problem: Unable to change the system IP address because
you cannot access the CLI
This topic helps you if you plan to change the system IP address using the
chsytemip CLI command but can not ssh to the system IP address to access the
CLI. For example, when another machine on your network is using the same IP
address.
About this task
If you need to change the IP settings on the storage system but can not ssh on to
the current system IP to run the chsystemip CLI command then use a nodes
canister service IP address to access the CLI. Find the service IP address for each
node canister in satask_results.html that was returned on the USB flash drive when
the Storwize V7000 was initialized or any time that you insert the USB flash drive
into the control enclosure. You should also be able to tell which node canister is
currently the main configuration node.
If the control enclosure service IP addresses cannot be reached using ssh, then it
can be set using the InitTool and USB flash drive. Refer to "Procedure: Changing
the service IP address of a node canister" on page 220.
Changing the system IP of the control enclosure using the service CLI:
Login to the service IP of the main configuration node canister using ssh as
superuser. The default password is passw0rd. Issue the chsystemip CLI command
to set new IP values. Here is an example:
>ssh superuser@<service-ip>
$ chsystemip -clusterip 9.20.136.5 -gw 9.20.136.1 -mask 255.255.255.0 -port 1
You may receive the following error:
CMMVC5732E The command cannot be initiated because it was not run on the configuration node.
This may indicate that the node you are currently logged in to is not the
configuration node for the system. Log out and login using ssh to the other node
canister service IP. Then issue the chsystemip command again.
If your system includes file modules that have not been initialized yet (for
example, the blue identify indicators are blinking) then start the USB initialization
process again but this time provide the new Storwize V7000 system IP. This time
there is no need to insert the USB flash drive into the control enclosure because it
will ignore the mknascluster command in satask.txt; the block cluster is already
made but the USB flash drive should be successfully initialized.
