Torsten is correct. You create raid 0 for each disk then they will show up in sam.

Hmmm, but why not mirroring the logical drives?



This will be much more secure.

Hi,

I have created raid0
by using below command

# saconfig /dev/ciss0 -R 0 -p 0x5000c5001d44a9e5
Logical drive 1 created

But its device file is showing NA.

How to i use this logical volumne?


---------- LOGICAL DRIVE 1 ----------

Device File = NA
RAID Level = 0
Size = 139982 MB
Stripe Size = 128 KB
Status = OK

Participating Physical Drive(s):

Ct Enc Bay WWID

Once create you need to run "insf" to create the device file.

# insf -e -H

[shikhar_1]

should be /dev/ciss1??
