Re: RAID config on HP 2300 Disk System
I don't believe it has any RAID capability. Look at the following document.
http://h200007.www2.hp.com/bc/docs/support/SupportManual/lpg29283/lpg29283.pdf
You may have to do mirror or stripe or extent level striping on the OS if you need RAID configuration. VxVM offers more options.

Re: RAID config on HP 2300 Disk System
Hi Karl,
Yes, there is a Raid Card installed in your system.
disk 5 0/10/0/1.0.0.0 sdisk CLAIMED DEVICE I2O RAID5
/dev/dsk/c4t0d0 /dev/rdsk/c4t0d0
Your Raid Configuration is Raid-5.
For getting a detailed information on the Raid configuration, login as root
then, issue a command irm at the # prompt.
this will give you a menubased option for viewing the Raid Configuration.
Do not make any changes, without knowing the actual configuration of your existing setup, since it can destroy your entire data in that external disks.
Regards
Raneesh Vijayan

Re: RAID config on HP 2300 Disk System
I have checked with irm. It shows that it has a configuration of RAID5.
Thanks for the help.
Here are your points. :-D
