Change the Control Station hostname
You can change a VNX server’s Control Station hostname. The following procedure
uses the CLI. However, if you use the Unisphere software to manage the server,
use it to make the hostname change instead.
In the following procedure, the Control Station hostname was changed from Eng_1
to cs100.
!
CAUTION
!
If you use the CLI to change the Control Station hostname and use the Unisphere
software to manage the server, ensure that you follow this procedure carefully.
Otherwise, you will not be able to create file systems by using the Unisphere
software.
Step Action
1. Add the new hostname to either DNS or the VNX system. To make changes to DNS,
check the DNS documentation. This procedure adds the new hostname to the VNX
system only.
Log in to the Control Station as root.
2. To verify the current environment, type:
# hostname
Output:
Eng_1
3. To display information about the Control Station, including its hostname and ID, type:
# nas_cel -list
Output:
id name owner mount_dev channel net_path CMU
0 Eng_1 0 172.24.101.100 APM04490091900
4. Open the /etc/hosts file with a text editor to see the entry for the current hostname. Add
the entry for the new hostname.
For example, add the new hostname cs100 to the file:
id name owner mount_dev channel net_path CMU
0 cs100 0 172.24.102.236 APM000420008180000
3 cs110 0 172.24.102.240 APM000438070430000
5. Save the file and exit.
