Mirroring Problems with rx2620

Ralf Buchhold — Wed, 09 Mar 2005 03:35:35 GMT

Hello
I have a problem when i want to mirror the root disk with an other disk in a disksubsystem.
I do everything from the sw-Rec-Handbook Chapter 29. But when I want to boot from the mirror-disk. No system is found. Any idea ?
Thank Ralf

Hi Ralf,

What does setboot say about the boot settings on the disks.

# setboot
Primary bootpath : 0/0/1/1.2.0
Alternate bootpath : 0/0/2/0.2.0

Autoboot is ON (enabled)
Autosearch is ON (enabled)

Best regards,
Robert-Jan

Hi Ralf

I have included the doc I made up for this.

It also includes the process to break a mirror

Did you try to recreate it?
Maybe something gone wrong.
