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:
- Log on any machine which is on the same network subnet that the Storwize V7000 Unified system will use for management communications. That is, it
has the same network gateway IP address set and the same subnet mask
set as the Unified system will use.
- Ping the network Gateway IP address that the Storwize V7000 Unified system will use. This should indicate 0% packet loss. For example:
ping
123.123.123.1
- If 2 was
successful then ping each of the following IP addresses that you will
be providing to InitTool.exe. Each should indicate 100 % packet loss.
- Storwize V7000 system primary IP address
- Storwize V7000 system secondary IP address 2 (if you intend to set this )
- Storwize V7000 node canister 1 service IP address ( if you intend to set
this )
- Storwize V7000 node canister 2 service IP address ( if you intend to set
this )
- Storwize V7000 Unified management IP address
- File module 1 IP address
- File module 2 IP address
- If you are utilizing DNS on your network, then the DNS entry for
each IP in 3 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
