How to manually sys-unconfig when single-user mode not an option?
Hi Gurus,
QUESTION
Although sys-unconfig is great, due to remote-site limitations
(no console) I cannot reboot into single user mode to input new
hostname/IP/etc... settings, what are *ALL* of the little things
sys-unconfig touches that I would need to manually modify before
initiating a reboot?
BTW: I am currently running on another disk/OS-install than the
one I plan to modify then reboot from. See "Additional Details"
further below.
RESEARCH SO FAR
According to sys-unconfig man page, the following files are
involved. Most are straightforward, but I'm not familiar with
some:
Comfortable changing these...
/etc/default/init
/etc/defaultdomain
/etc/defaultrouter
/etc/hostname.interface
/etc/inet/hosts
/etc/inet/netmasks
/etc/nodename
/etc/shadow
/etc/vfstab
/var/nis/NIS_COLD_START
/var/yp/binding/*/ypservers
Not so sure about mucking around with these...
/etc/net/*/hosts
/etc/.rootkey
Other files or areas not mentioned in the man page that will
cause trouble?
/?/?/???
ADDITIONAL DETAILS
E-450 SunOS 5.9 Generic_112233-08 sun4u sparc SUNW,Ultra-4
I've been asked to duplicate a remote E-450 onto another
remote E-450. Unfortunately, I do *not* have console access.
I am running on disk0 of the E450 I'm building (default
install of Solaris 9). I have created the boot block and
restored the root file system of the original server onto
disk1 of the new E450 (also Solaris 9).
The original server is still online. IF I were on-site, I
would disconnect the new 450 from the network, boot up as the
original host, sys-unconfig (auto-reboot into single user
mode), assign name/IP/etc, reboot and connect back to network.
But I'm not on-site and don't have console access.
Since I have the new root filesystem mounted, I *can* go in and
manually modify /etc/hosts and other files to the new settings,
use the eeprom command to set the host to boot from this newly
ufsrestored slice, and reboot. (Actually, I'll set boot-device
to "disk1 disk0" in case disk1 doesn't work.)
AGAIN, MY QUESTION IS
Since I cannot reboot into single user mode to input new
hostname/IP/etc... settings, what are *all* of the little things
sys-unconfig touches that I would need to manually modify before
initiating a reboot?
TIA for tips. I will summarize useful info.
