Environment: Solaris 5.8 Sunfire V1280. VRTSvxvm VERSION: 3.5,REV=06.21.2002.23.14 (yes, I know. very very old)
Server has encapsulated root/root mirror disks. Somehow critical files were removed or permissions changed so that the server boots, but nobody can login "No shell" is the reply. Also during boot other "missing directory" messages pop up.
I am booted from CDROM in single user mode, and want a procedure to get into the root filesystem; then I will explore what is missing and attempt to restore it, and then try to boot and login again. Also, because we were locked out, we did a reset-all on the system and now some of the filesytems want fsck, but it cannot be done from the boot sequence because we get "No shell" when trying to get into single user mode. I suspect the fsck will be the first thing we need to do.
The issue I need help with is determining how to do that, considering that the root disk is encapsulated. It would likely be the same procedure as if you were trying to recover the root password manually; one disk is now different from the other one. How do you get them all working, assuming that the changes to root disk were effective?
Prompt reply is appreciated, this production server is in the middle of a change window and we are running out of time.
