RAID 1 mirroring

Hello,

I have a Sun system running Solaris 9. It has two 36 Gb scsi disks in it;
c0t0d0 and c0t1d0.

I have installed the O/S to c0t0d0.

I'd like to mirror these disks (RAID 1) using Solaris Volume Manager. Can
someone tell the simplest (no frills) method, and commands to achieve this?


Thank you.

Read Sun document 806-3205.pdf or later (that one is actually the
User's Guide for SDS 4.2.1 for Solaris 8 but its all much the
same). The basic commands are metadb first then metaroot and
metattach etc.

All the docs for Solaris 9 (including Solaris Volume Manager) are online
at docs.sun.com if you don't have other copies.

You might want to read the overview of SVM if you haven't used DiskSuite
in the past, but basically you need to allocate space for the database
that the volume manager uses, and then activate it.

The overview of it.

How to create it.

Then when volume manager is initialized, you'll create a Mirror/RAID0
object with the root filesystem, swap, and any other filesystems on your
root disk.
