Building new ldom server--many questions

Hi All,

I am just starting to build T5240 servers with ldoms in the hope of consolidating some of my older hardware (280Rs, 220Rs, etc).

These old servers are currently set up using disksuite mirroring to backup all root and data drives.

I am new to Ldoms, zpools, zfs, raidctl, et al.

In ldom i/o best practices guide there is a reference to starting your system build with hardware raid so I setup one using the following command prior to installing solaris10 from dvd:

# raidctl -c -r 1 c1t0d0 c1t1d0

I next proceeded to install solaris10 on this raid using the zfs root option.

Using Solaris 10 5/09 with ldom 1.2 and all appropriate patches/firmware.

Questions:

1--How do I monitor/administer the hardware raid? Are there similar admin commands like metastat that I'm familiar with in disksuite?

2--how do I setup root for my guest domains? Based on readings, I think create a virtual disk from a file built on the raid drive would make sense, but not sure how...or if this is best.

3--how does zfs/zpools relate or work with hardware raid? does the use of both make sense?

Thanks for help

Jim

raidctl -l ...

It is the way to do it.

They don't.

Not that much. Better to let ZFS handle the RAID alone.

Thanks for the info jlliagre...I'll use raidctl -l , in a script to check drive health.
