Server not comming after reboot :(

[bullz]

Hello Guruz,

I have just changed the hostname using set_parms hostname command... After the reboot, server seems to be not booting after changing hostname.

While booting from Alom, i have got the below error as shown below.

/sbin/auto_parms: DHCP access is disabled (see /etc/auto_parms.log)

I guess its something to do with auto_boot?
Please advice

Hi,

What is the configuration in /etc/netconf ?

Is the DHCP enables? if no then do you have a valid IP address configured in /etc/netconf?

try to boot it in single user mod if it is not booting in any other mod.

Hi,

I think DHCP is enabled, ensure DHCP server is up.

If server is up, try to follow Sooraj's step,note that the file is /etc/rc.config.d/netconf

actually, it isn't. DHCP is a method to dynamically assign ip address at boot time. You may not ever have had it configured or used it. If you didn't then that message is normal.

What makes you think that the server didn't come back after reboot? if you're testing by trying to ping (or otherwise connect) via the newly-assigned hostname (and you use DNS) did you update the DNS entries? Can you access it via the ip address? Can you access it via the OLD name?

Again, what do you see that makes you think it didn't come up? And what commands have you tried? What errors (if any) did they generate?

Bultz,
Try booting off single user mode, and revert back the changes , and see what happens.

- what is the version of os. & hw model.
- Did you modified netconf.
- check files under /etc/rc.config.d/

Also pls provide more data to troubleshoot.


Cheers,
Raj.

What, EXACTLY, does the first sentece mean? The server doesn't autoboot?

What command(s) are you issuing to reboot and what action(s) do you take to correct the issue?

[unix adm]

Try to boot the server once again monitor the boot logs carefully via GSP or MP , give last 10 lines of message where it gets stuck during boot.


Whats the hardware model & OS of the server?



Thanks - Rajeev

As old school also indicated, your messages are quite contradictory. If it is rebooting properly, what do you mean by "not coming up after reboot" ? It is up but not accessible over the network ? If you are on the console, could you please elaborate the error messages you see ?
