Netware 5.0 SP6A
Not new to Netware, but just learning about mirroring and am curious about the following:
I have a server that had one drive in it. I added second drive, brought up server, load nwconfig, mirrored the original drive to the new one. That seemed to go OK. It re-mirrored and the system is running fine.
One of the reasons for mirroring is when I do an install of an upgrade, I want to break mirror, do the upgrade. If all OK, remirror. If not, switch drives (make the former mirror the primary) and I'm back to the original working system.
As a test I did this (broke mirror) and it asked me do I want to preserve the volume sys information on the mirrored drive. Since the reason I did this was to use the drive in case of a problem with the install, I said yes. I then
got a bunch of error messages to the effect that I have two volumes named sys (well, I assumed I would since that is the very nature of a mirror - everything the same). Anyway, I hit OK and then got a message something to the effect that volume sys is mismatched, starts at sector 0 and ends at sector so and so. I hit OK again and the mirror was broken. At this point is the mirrored drive a valid drive to use if the other one had a bad install and I wanted to get back to my starting point?
After a while, I remirrored. As soon as I added the mirror drive back to the set in nwconfig, I got all these same error messages again about there being two volumes named sys and the sectors not being right. I kept pushing OK til no more messages. The drives re-mirrored and things are
running along fine. Is this mirror set good?
All these messages were very cryptic to me and I really could find no references to them on the internet. At this point I am not sure if the mirroring is OK or not or if I am doing this right or not. The system seems to be mirrored and is running fine, but it doesn't seem right that I should get all these error-type messages when breaking mirror or setting up the mirror again.
Thank You
