Our company has created a procedure for creating a backup root disk called BROOT. All new boxes are put into production with this functionality.
It was meant for an add'l recovery disk for VG00, but it can be used to copy from one disk to another, when you might ever upgrade a Disk to a larger one.
Here is the script. We have a script that creates this script, but this can be edited and reused. This should give you something to work with.
I didn't write this, but it is very good for this type of work

I have a SunOS 5.8 server. I suspect there may be errors with one of the physical disks (based on someone reporting hearing a "clicking sound" during the night shift, however I do not hear anything this morning).
Which log would show this?
Thank you. (2 Replies)
