[SunHELP] Disk Mirroring and failover

Tue May 11 14:43:31 CDT 2004

Yo,

Naw man, the mirror disk will kick in...not to worry...you don't have to
reboot or anything...this stuff is for high availability, so it keeps
running...depending on the system (if you have hot swap disks), you replace
bad disk, resync, and drive on...even on OS disk...we been doing this for a
few years...

I believe if the main drive fails, you would have to reboot into the ok 
prompt and then get the boot command to boot off of the second drive. Then 
replace the original drive and then rebuild the mirror.

If the mirrored drive fails, you only have to hotswap a new drive in and 
rebuild the mirror.
