It calls the svctask chsystemip command if the USB flash drive is inserted in the
configuration node canister, Otherwise it will blink the amber identify LED of the
node canister that is the configuration node.
If the amber identify LED for a different node canister starts to blink then move
the USB flash drive over to that node canister because it is the configuration node.
When the amber LED turns off you can move the USB flash drive to one of the file
modules so that it will use the clitask.txt file to change the file module
management IP addresses.
Leave the USB flash drive in the file module for at least two minutes before you
remove it. Use a workstation to check the clitask_results.txt and satask.txt results
files on the USB flash drive.
If the IP address change was successful then you must run the startmgtsrv -r
command to restart the management service so that it will not continue to ssh
commands to the old system IP address of the volume storage system.
For example, on a Linux workstation with network access to the new management
IP address:
satask setsystemip -systemip 123.123.123.20 -gw 123.123.123.1 -mask 255.255.255.0 -consoleip
123.123.123.10
You should now be able to access the management GUI which you can use to
change any other IP address that need to be changed.
Here is an example of what could be in the clitask.txt file:
chnwmgt --serviceip1 123.123.123.11 --serviceip2 123.123.123.12 --mgtip 123.123.123.10 --gateway
123.123.123.1 --netmask 255.255.255.0 --force
chstoragesystem --ip1 123.123.123.20
Here is an example of what could be in the satak.txt file:
satask setsystemip -systemip 123.123.123.20 -gw 123.123.123.1 -mask 255.255.255.0 -consoleip
123.123.123.10
Query status command:
Use this command to determine the current service state of the node canister.
Syntax
sainfo getstatus
Parameters
None.
Description
This command writes the output from each node canister to the USB flash drive.
This command calls the sainfo lsservicenodes command, the sainfo
lsservicestatus command, and the sainfo lsservicerecommendation command.
