Passwd Recovery

I need to recover my Root Paswd.
I am in the SingelUser mode. When I try to say Mount -a.
it only mounts /proc. and /usr and /var doesnt get mounted.
I am new to Tru 64 but have been on HPUX for along time.
When I say mount -a it gives me a device file name of one of the Vol grp and says invvalid device file.
But it works fine when I boot to multiuser mode.
Can U tell me how to recover my root passwd

Re: Passwd Recovery


Have you tried mount -u?

From the man page

-u Requests that the system remount a file system so that it can update any incore data blocks for ufs and AdvFS type file systems. This flag works only for ufs and AdvFS file systems that are currently mounted read-only and updates the file systems from read-only to read-write.

For example, the mount -u / command updates the root file system from read-only to read-write.

Live long and prosper
