Checking that IP addresses are not already in use
It is very important to check that the IP addresses that you give to the InitTool.exe
are not already in use.
About this task
If you provide an IP address that is already in use then the initial setup may
appear to be successful and the system could work for some time before random
problems start to happen, which could be very hard to troubleshoot.
A reliable way to check that an IP address is not already in use is to logon to a
machine that is in the same subnet as the Storwize V7000 Unified system will use
for management communications. Then ping the new IP addresses. For example,
ping each of the IP addresses that you intend to use in the InitTool.exe. Note that
the security setup of your network may not allow IP hosts to respond to ping.
Follow this process:
1. Log on any machine which is on the same network subnet that the Storwize
2. Ping the network Gateway IP address that the Storwize V7000 Unified system

should also be checked utilizing the nslookup command to ensure that the
DNS names match what you expect. nslookup can be used the same way in
Linux, Windows and MacOS):
nslookup<IP Address> For example, Output from Windows 7:
nslookup 123.123.123.10
Server: mydns.mysite.com
Address: 123.123.123.102
Name: mysys.mysite.com
Address: 123.123.123.10
