Operating Systems Solaris Failed to mount /usr Post 302640383 by juan.brein on Monday 14th of May 2012 04:34:39 PM

Try to fsck all the filesystems multiple times, sounds crazy but sometimes just one time is not enough. Then mount all the filesystems and try to check files and directory contents. if you have similar installation on another system you can try to count the files and sizes and see if they differ a lot with the problematic one. Check the content of the most important files in /etc directory like system, passwd, shadow, vfstab, svc/repository.db, hosts, inittab.. etc.
If you still have problems take the disk out and try to boot on another HW... if it works then the problem is on the other cabinet.
If it doesn't boot restore from backup.
You can also try to boot with boot -m debug, or boot -v
Hope it helps... there are many other things you can try but that's a beginning
