Disaster recovery
have a 2 drive mirror set, drive 0 and 1.
The system is using a Smart Array 5304. I have created a drive rotation of 3 drives for the purpose of Disaster recovery. What I do is once a week I remove drive 1 and replace it with the next drive in the rotation and it the new drive is rebuilt with the information currently on drive 0 and thus I'm back to a mirror set.
Now here is my question: I want to do a failover test and my understanding is that I can do this by shutting down the system, removing the current 2 drive set and replacing them with the last drive from rotation set. Now I would place this single drive in slot 0 and I should be able to just boot normally and basically have the system as it was the week prior. Remember I'm taking the week before drive 1 and placing it where drive 0 would go. After the test was completed successfully, I should just be able to shut-down the system remove this drive and replace with the original two drives and reboot back into the current system.
No problem to do that if I use a integrate array controller
but with the 5304 smart array controller big problem this controller don't boot.
If I clear the system with erase utility and put back the original disk no problem to boot.
but if I try to do with one disk only nothing work
Thanks

Re: Disaster recovery
Why don't you try drive in slot 1 instead of slot 0.

Re: Disaster recovery
I try this is the same problem,
If your search in this forum 4 people ask this question
and Compaq give 2 answer
answer #1 this should be work no prolem.
answer#2 this is very hard to do and we don't support take your tape backup.
But Compaq never try.

Old compaq and integrate smart array controller support drive roaming
