NetServer LH Pro Mirror-Raid 5 Help

[Steven Chen_1]

Hi gurus,

I would appreciated it if someone could give me some procedures to break mirror (2 HDs) and then add 3 HDs for Raid 5 on HP netserver LHPro.

The server contains Exchange Server and its files. It is important that the files are not lost.

Any comment are appreciated.

Do you have a hardware RAID configured (= RAID controller) or a software RAID (done with the operating system)?
If this is hardware RAID, what RAID controller is being used?

Steven,

If you have a Netraid configuration and the Mirror only has 1 logical drive, then you can just drag 'n drop the 3 extra disks to the logical drive (in Netraid Assistant) and migrate to RAID5.
The extra disk space will appear as unused space on the disk in disk administrator, so you can create a partition on it.

Marco.

Thanks for the help.

I have NetRaid, hardware raid controller. Do not remember what version is. Any detail procedures I should follow?

Thanks a lot.

Take a look at the Netraid User's Guide at http://netserver.hp.com/docs/download.asp?file=netrdusergd.pdf Chapter 6 tells you all about capacity expansion.

hi
first, I will be sure: you have 2 hdd in raid one (I suppose 4 GB) you need to expand your raid to reach a raid 5 with 2 + 3 hdd >> 5 hdd 4 gb >> 16 gbyte total capacity.

If this is the case, you didn't need to break the raid.

You have to Backup all your data (for precaution), then install netraid assistant, then start the program, it will perform a scan and dive you the situation of the hdd on the scsi channel, you should see two hdd configured a0-0 and a0-1 + tree hdd in ready.

you select the tree hdd in ready and drag/drop on the logical device, a pop-up window will ask you which kind of raid level you want to reach, you select 5 and tre operation will start.

this operation can also performed off-line, starting with cd-navigator and running netraid assistant (better from a last revision of cd)

bye
