>> How do i verify that RAID 0+1 is configure on it.

At the SRM prompt (hardware prompt) run:

show dev

You will see some DK* devices. If you see the same number of disks as the number of physical disks, you don't have a hardware RAID configured. When you configure a raid, two or more disks will be shown as one in the SRM.

>> s it done at the OS level or the hardware prompt?

You can create software mirror using the O.S. LSM, or you can create hardware mirror if you have a RAID controller.

As I recall, those Mylex controllers had a special utility that you had to use to set up your RAID to present to the host. Do you have a CD with something called ACU (Array Configuration Utility) on it? Boot from that CD and you should be able to see your configuration.

Re: Alpha ES 40

1)Locate an Alpha Firmware CD which has the UTILITY\SWXCRMGR\RA200RCU.EXE file.

2)At POO>>>, type arc and you will get a menu
from which you should choose the option 'Run Program'. When prompted for a filename, type:

CD:\UTILITY\SWXCRMGR\RA200RCU.EXE

This will provide you with a menu to perform several tasks.
