6. To ping both the new and the old Control Station hostnames, type:
# ping cs100
PING cs100.nasdocs.emc.com (172.24.101.100) from 172.24.101.100 :
56(84) bytes of data.
64 bytes from Eng_1.nasdocs.emc.com (172.24.101.100): icmp_seq=0
ttl=255 time=436 usec
# ping Eng_1
PING Eng_1.nasdocs.emc.com (172.24.101.100) from 172.24.101.100 :
56(84) bytes of data.
64 bytes from Eng_1.nasdocs.emc.com (172.24.101.100): icmp_seq=0

7. Change the hostname on the Control Station by typing:
# /bin/hostname cs100
8. To verify the new hostname, type:
# hostname
Output:
cs100
9. Change the hostname to the new hostname in the /etc/sysconfig/network file, using a text
editor. This will make the hostname permanent when there is a restart:
NETWORKING=yes
FORWARD_IPV4=false
GATEWAY=172.24.101.254
GATEWAYDEV=eth3
DOMAINNAME=nasdocs.emc.com
HOSTNAME=cs100
10. Save the file and exit.
11. Remove the old hostname from DNS or the /etc/hosts file.
Open the /etc/hosts file with a text editor and delete the old hostname.
Example:
There will be only one Control Station hostname entry in the file after you delete the old
hostname, cs100.
172.24.101.100 cs100.nasdocs.emc.com cs100
12. Save the file and exit.
13. To update the local hostname, type:
# nas_cel -update id=0
Output:
id = 0
name = cs100
owner = 0
device =
channel =
net_path = 172.24.101.100
celerra_id = APM04490091900
