How best to copy a boot hard drive?
Posted on 1998-11-11
I am using solaris 2.5.1 x86 and would like to make a mirror copy of my main hard drive (it has /, /usr,/tmp,etc., on it).
I would like to know how best to make a copy of this drive, so that if the one running the system crashes, I can jsut throw the copied drive in there and fire the machine up again. These are SCSI drives in a Dell 4200.
I don't want to use 'ufsdump' because it requires the drive to be unmounted, and these sytems can't be taken down for long periods of time - do maybe 'dd' would work?
Anyway, a detailed response would be appreciated, including how to make the drive bootable, and what order I need to take to get the os to recognize the blank drive, do I need to format it if its going to be an exact duplicate of the drive I want to copy, etc...
Thanks in advance,
