HOSTNAME configuration in Unix B.11.31

[jason-dr]

Greetings to all,

I am facing an error with Hostname in one of our HPVM server.

Here we can see Hostname and uname -a command's are giving different hostname's insted of same. 
# hostname
meccapp106
# uname -a
HP-UX meccapp1 B.11.31 U ia64 1508026702 unlimited-user license
#

I hope everyone understand my problem
Kindly share any suggestions regarding this.

Thanks ,
Jason

That's a standard feature to ensure backwards compatibility. You can override if you want by changing a kernel tuneable. All the details, including the things you will need to think about, are decribed in this white paper:

Hello jason-dr,

Output of command hostname shows meccapp106 (10 characters) while uname -a shows only 8 of them meccapp1 .

Please change the kernel tunable expanded_node_host_names set to 1, followed by running # uname -S meccapp106.
This will help you get entire 10 characters for uname -a output .

You may refer the document https://support.hpe.com/hpesc/public/docDisplay?docId=c01925495&docLocale=en_US for details .
