Adding drives to DL380 G5 P400 Smart Array Controller

Dear Experts,

We have an HP DL380 G5 with a P400 Smart Array controller. There are currently one 146Gb SAS drive in the system as 0. In this disk RHEL 5.3 64 bit OS was installed & it is now in production. Now we want to add a new 146GB SAS disk into bay 2 & want to build RAID 1+0 with these two disks. My query is after building RAID 1+0 is Data of Old Disk (Bay 1) will be lost or It will sync data from Bay 1 disk to Bay 2 Disk without Data loosing.

Thanks
Minhaz

Hi Md. Minhaz Khan,
If you have set the Drive as RAID 0, and you have BBWC(Controller cache) installed with P400. You would be able to expand and extend array from RAID 0 to RAID 1, using HP Array Configuration Utility, without loosing data.
It will sync with second drive that you will add to the server.
Please take a look at Array Configuration Utility Users Guide below to know about array expansion and extension;
http://www.google.co.in/url?sa=t&source=web&cd=1&sqi=2&ved=0CBYQFjAA&url=http%3A%2F%2Fbizsupport1.austin.hp.com%2Fbc%2Fdocs%2Fsupport%2FSupportManual%2Fc00709035%2Fc00709035.pdf&ei=SBU_Tcf_A4nTrQf-6aTSCA&usg=AFQjCNHAvSqR-_4949uNoUY3HkDQgDxsRQ&sig2=5Kh7Q2HAlJae7eUq7lZGYg

In case you haven't set existing drive as RAID 0, then you will have to re-create RAID 1 with additional drive, and data will be lost.

Please assign points if you think information provided was useful!

Hi Minhaz,

just an addition to the previous post.

YOu got two options :

1. Migrate existing Raid 0 (with 1 disk) to Raid 1 by adding 1 more drive.

2. increase the capacity of an existing array by expanding it. So you may add 1 drive to existing Raid 0.

please let me know if you need more clarification
thanks
