Operating Systems AIX won't mount /usr...won't boot fully Post 302245052 by rbruder on Thursday 9th of October 2008 08:31:13 AM

I believe you should be pressing "1" to go into SMS mode not F5. Once you get into maintenance mode, there is a very limited set of commands you can use if /usr cannot be mounted. Your only option may be a restore at this point.

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. SunOS 5.11 21 Aug 2008 sulogin(1M)
