Know i have a question about the behaviour: I have two luns from to different storage systems via dm multipath Lets say 50 GB each. Now i want to mirror them. Should i use dmraid or dmmirror? How can i find out in which state the lvs are? How does the system behave like, when a lun is missing? If a want to switch a vg, is a vgchange -an on host a sufficient? As u can see, there are many questions.
