okay, lets say you have a basic understanding of linux. and you find out you need to have the same uid and gid between a couple of servers for say NFS sharing. At this point i would point out using some shared service, like LDAP, or NIS, for user control would be idle. but it is to late. you have established systems. and you need to change these users to match between all the systems. AND you need to update files after the change.

Say you have a Fibre disk in Solaris. that disk in in sun cluster, is a mirror in veritas to a second disk. now say that disk is removed before you remove it in veritas and on the system. so you have this disk just sitting there in solaris that does not really exist. just sitting there staring at you. Veritas lists the disk as error [since it no longer exists]. and you have removed it from the plex, but other wise have left the disk alone.
