Cannot boot in single-user mode
I have Sun 240 server with Solaris 8 installed. I go to OBP and try to boot in single-user mode but it is getting hung in the middle and the only way to get out of this situation is by going to the LOM and resetting the server. Here is what is happening:
{0} ok boot -s
SC Alert: Host System has Reset
SC Alert: CRITICAL ALARM is set

Nothing comes up after that. It is then when I go to the LOM (#.) and reset the server. Can anyone help troubleshoot this?

LEARN ABOUT OPENSOLARIS
sulogin
sulogin(1M) System Administration Commands sulogin(1M)
NAME
sulogin - access single-user mode
SYNOPSIS
sulogin
DESCRIPTION
The sulogin utility is automatically invoked by init when the system is first started. It prompts the user to type a user name and password
to enter system maintenance mode (single-user mode) or to type EOF (typically CTRL-D) for normal startup (multi-user mode). The user should
never directly invoke sulogin. The user must have the solaris.system.maintenance authorization.
The sulogin utility can prompt the user to enter the root password on a variable number of serial console devices, in addition to the tra-
ditional console device. See consadm(1M) and msglog(7D) for a description of how to configure a serial device to display the single-user
login prompt.
FILES
/etc/default/sulogin
Default value can be set for the following flag:
PASSREQ
Determines if login requires a password. Default is PASSREQ=YES.
/etc/default/login
Default value can be set for the following flag:
SLEEPTIME
If present, sets the number of seconds to wait before login failure is printed to the screen and another login attempt is allowed.
Default is 4 seconds. Minimum is 0 seconds. Maximum is 5 seconds.
Both su(1M) and login(1) are affected by the value of SLEEPTIME.
ATTRIBUTES
See attributes(5) for descriptions of the following attributes:
+-----------------------------+-----------------------------+
| ATTRIBUTE TYPE | ATTRIBUTE VALUE |
+-----------------------------+-----------------------------+
|Availability |SUNWcsr |
+-----------------------------+-----------------------------+
SEE ALSO
auths(1), login(1), consadm(1M), init(1M), su(1M), attributes(5), msglog(7D)
NOTES
By default, the root user has all authorizations.
Granting the solaris.system.maintenance authorization to the Console User Rights Profile may have an undesirable side effect of granting
the currently logged in user maintenance mode access. The solaris.system.maintenance authorization should be directly granted to appropri-
ate users rather than through the Console User Rights Profile.
