How to add a new RAID on P400

Hello



On Proliant ML570 G4 I have a P400 Smart Array on which 3 RAIDs are set , the 1st RAID 1+0 is made of 2 disks,the 2nd and 3rd are RAID 5 made
of 4 disks each, all disks in those RAIDs are 72 GB 15K SAS . i want to expand the space on the server and i've got 2 new 72 GB 10K SAS disks each to prevent unrecovereble crash , i dont wont to mix 72 GB 15K SAS and 72 GB 10K SAS in same RAID by expanding existing RAIDs, instead i want to setup a new group of disks
using those new disks,


my problem here is it possible to setup a 4th RAID(say RAID 1+0 )made of the 2 disk 72 GB 10K wich will be expandable with disks of
same specifications (disk 72 GB 10K)




below is the of RAIDs configuration:

Re: How to add a new RAID on P400

Yes, you can do that. No problem.

Just open ACU, and create new array and logical drive. You don't even need to reboot.

ps.
There's no problem in using different disk within an array.
And you can replace disks in an array on-line to larger disks, and then extend the logical drive, if you operating system support it.
