If you did enter the wrong IP address for the gateway of this subnet and you have
the correct gateway IP address ready, then it is possible to re-configure the control
enclosure and file module to use the correct management gateway IP address.
If you have access to a computer that is plugged into the same Ethernet switch as
the 1 Gbps Ethernet port 3 of each file module and the 1 Gbps Ethernet port 1 of
each node canister in the control enclosure, then you may be able to ssh from it to
the management IP address and log on as admin.
In this example, the default password is admin001:
ssh admin@<management IP address>
Use the lssystemip CLI command to show you the current management IP address
setting on the control enclosure:
[kd52v6h.ibm]$ lssystemip
cluster_id cluster_name location port_id IP_address subnet_mask
IP_address_6 prefix_6 gateway_6
00000200A9E0089E ifscluster-svt2 local 1 9.71.16.208 255.255.255.0 9.71.16.2
00000200A9E0089E ifscluster-svt2 local 2
If this command fails because the file module could not ssh to the control
enclosure then refer to Troubleshooting > Getting started troubleshooting >
Installation troubleshooting > Problems with initial configuration from the
Problem Determination Guide.
Use the chsystemip CLI command to change the managed gateway IP address
setting on the control enclosure. (This must be done first before you change the
management gateway IP address setting on the file modules):
[kd52v6h.ibm]$ chsystemip -gw 9.71.16.1 -port 1
The active management node on the file module is not able to ssh CLI commands
to the control enclosure until you change the management gateway setting to
match the setting on the control enclosure. Use the lsnwmgt CLI command to
show you the current management IP address setting on the file modules.
[kd52v6h.ibm]$ lsnwmgt
Interface Service IP Node1 Service IP Node2 Management IP Network Gateway LAN ID
ethX0 9.71.16.204 9.71.16.205 9.71.16.216 255.255.255.0 9.71.16.2
EFSSG1000I The command completed successfully
Use the chnwmgt CLI command to change the managed gateway IP address
setting on the file modules.
[kd52v6h.ibm]$ chnwmgt --gateway 9.71.16.1
EFSSG0015I Refreshing data.
EFSSG1000I The command completed successfully
The active management node on the file module should now be able to ssh CLI
commands to the control enclosure again. You should be able to access the
management GUI or CLI from a computer, which is on a different subnet or
different Ethernet switch to the Storwize V7000 Unified system. The link to the
management GUI from the InitTool.exe panel should now work.
satask.txt commands
If you are creating the satask.txt command file by using a text editor, the file
must contain a single command on a single line in the file.
