Re: Unload/Reload



fixed

Rob,

How long it takes to recover is a big question. I have customers were it fits the rule of thumb, about 1.5 times the save time to recover (not including creating RAID sets or drive initialization) but if I remember correctly, you have Domino and I suspect you use SAVDOMBRM. In this case you will run into some intrigue restoring depending on your directory structure. SAVDOMBRM does not save the parent directories, so ownerships and authorities might not get put down as you expect.

One customer I just did recovery testing for took about 8 hours total for a "21" save. Over 70 hours to recover because there were a shade over 50 million IFS objects DB/2 went down in a snap, but the rest of the system, not so much. This customer is now installing a brand new CBU box with PowerHA to replicate his system since 3 - 4 days of downtime would not be acceptable to the business. (remember disk init is not all that fast and in a real recovery you will have to do it)
