Mirroring Drives on a SunBlade 150

[Michael42]

Hello,
On a SunBlade 150 running Solaris 8 is it possible to mirror two identicle 40 gig IDE drives?

What software is required?
What are the steps?

I am not sure where to start.


Thanks,

Yes, you will need to either use Solaris Solstice or Veritas Volume Manager.

Your other option would be do run a manual 'offline' mirror. Slice your alternate disk the same as your primary and then do a dd copy of each slice on the primary disk to the alternate disk. You can easily script this and run it periodically via cron.

If you're doing manual duplicating via a cron, then it's
a lot quicker to use rdist than dd.

I guess using the Veritas Volume Manager strength is near Real-time data mirror perhaps it's cons are loss of performance and extra software to install\maintain.

The dd/rdist method looks promising. It looks more fleixble perhaps. I could cron a "sync" at least once a day. Does anyone know how rdist would behave in this scenario if data is changing while using rdist? I'd like to sync at noon also.




Thanks,
