rx6600 internal boot disk and SAS config

[Tim Nelson]

The rx6600s and SAS controllers for internal drives are new to me.

Just wanted to see what others are doing with this newer hardware.

My intention is to mirror ( raid1 ) my two internal drives that I will be using for booting the OS using the SAS controller features configured by the drvcfg command in the EFI shell. This is in lieu of using LVM mirroring of ol'.

Is configuring the mirroring from the SAS controller the new better practice ?

Comments / experiences welcomed.

Thanks all..

In case of a internal SAS controller I would configure an internal RAID.
See

http://docs.hp.com/en/J6369-90045/index.html

This makes things much easier.
Be aware that the procedures for different array controllers (e.g. SA P400) are different.

Of course you can use the internal SAS disks with LVM too, but in case of a disk replacement the procedures will become very "technical", see

http://docs.hp.com/en/J6369-90045/ch04s05.html

Notice a command line like this

# sasmgr replace_tgt -D /dev/sasd0 -q old_tgt=/dev/dsk/c3t2d0 -q new_tgt_hwpath=0/4/1/0.0.0.1.0

Compared to the swap-out and swap-in - what is easier?

I set up the raid1 at the controller level via the drvcfg. Pretty simple..

Thanks as always for the input.
