When you can ssh to the storage system IP then use the lssystem CLI command
on the storage system CLI to show you what it thinks that its system IP address is:
IBM_2076:tbcluster-ifs4:superuser>lssystemip
Check that these IP addresses and sub net mask are as expected. Use the
chsystemip CLI if you must change anything. Use ping to check the path back to
the management IP address.
IBM_2076:tbcluster-ifs4:superuser>ping 9.71.18.160
If the ping from the storage system CLI back to the management IP has 100%
packet loss then investigate the physical 1 Gbps Ethernet cabling and the
configuration of the Ethernet switch. Also check the Ethernet port LEDs on:
v Built in Ethernet port 3 of each file module
v Ethernet port 1 on each node canister of the control enclosure
If the ping from the Storwize V7000 to each file module has 0% packet loss, then
the ssh key should be reset. Follow the "Resetting the NAS ssh key for
configuration communications" on page 402 procedure in the Infomation Center to
reset the NAS key.
If you need to change the IP settings on the storage system but cannot use ssh to
access 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:
