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
This topic identifies the commands that can be run from a USB flash drive.
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. The commands that
you use are the same as the service CLI commands except where noted. Not all
service CLI commands can be run from the USB flash drive. The satask.txt
commands always run on the node that the USB flash drive is plugged into.
Reset service IP address and superuser password command:
Use this command to obtain service assistant access to a node canister even if the
current state of the node canister is unknown. The physical access to the node
canister is required and is used to authenticate the action.
