LSI1064 RAID 1 V215 HowTo?
So I've got a shiny new V215 server, jumpstarted to Solaris 10 Update 3. I try to mirror the OS disk:
# raidctl -f -c c1t0d0 c1t1d0
Cannot create RAID volume, disk "c1t0d0" is mounted .
Are we for real? I feel a rant coming on. Every box Sun builds has some insane defect or some engineering flaw that just makes it so hard to stand behind their hardware. Why can't they get it? Something as simple as a RAID controller! Look at an HP DL-360. The RAID controller is flawless. It's controlled in the BIOS, which makes OS interaction with the controller moot. We were set to buy a few hundred of the V215's, but guess what? Not on your life.
Sorry, vent off.
Does anyone know of a (argh...) work-around? How do I mirror the OS disk with this piece of dung RAID controller? (Is there a secret document somewhere?)
TIA....

Hello,
incidiently you already explained why creating a RAID works on the x64 system: When you configure the RAID in the BIOS none of the volumes is mounted. Invoking raidctl from the disk that is/becomes member of the RAID won't work.
Have you tried to boot from the Solaris CD and invoke raidctl to create the RAID ?
Alernatively you can add this disk preparation to jumpstart.
The procedure is to create the RAID and then install the OS.
I don't have access to a Sun with this (hardware) RAID capability, therefore I can't try if it works (and destroy the disk contents).
There are basically few choices:
- Try the above procedure
- Post to the next thread and maybe get an answer from Toze (who didn't return)
- Open a service case with Sun, either on contract or paid per incident
- Someone else post a direct answer
This is link to another thread about the LSI1064

Quote from a quote from the above thead
The LSI1064 HBA can enable up to two RAID volumes and, in
addition to IM volumes, also supports the RAID 0 volume
type, called an Integrated Stripe, or IS. Volumes of either
RAID type can be created on an LSI1064 only when no member
disks have mounted file systems, as the volume initializa-
tion destroys any data on member disks.
