About This Task - IBM Storwize V7000 Unified Problem Determination Manual

If the responses show more than one MAC address (in the square brackets) then
there is a duplicate IP address in the local network.
To check for a duplicate IP address in your wider network you can disconnect
Ethernet port 1 from each node canister and attempt to ping the IP address from
another system in the same subnet.
If you plan to change the IP settings on the storage system but can not ssh to the
current system IP to run the chsystemip CLI command then refer to "Problem:
Unable to change the system IP address because you cannot access the CLI."
If you plan to change the system IP address and can ssh to the current system IP
address, then you can run the chsystemip CLI command. Here is an example:
>ssh superuser@<system IP address>
$ chsystemip -clusterip 9.20.136.5 -gw 9.20.136.1 -mask 255.255.255.0 -port 1
The default password for superuser is passw0rd.
Update the file module's record of the control enclosure system IP:
To find the file module's current record of the control enclosure system IP address,
use the Storwize V7000 Unified management CLI to issue the lsstoragesystem
command. Here is an example:
>ssh admin@<management_IP>
[kd01ghf.ibm]$ lsstoragesystem
name
StorwizeV7000 9.11.137.130 9.11.137.130 00000200A2601508
EFSSG1000I The command completed successfully.
If the primary and secondary IP address shown by the lsstoragesystem CLI do
not match the system IP addresses shown in the output of the lssystemip CLI
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
