Upgrade Embedded SCSI to RAID
I currently have an ML370 configured with Windows 2000 Server SP4. The server is configured with one 18GB drive and one 145GB drive connected to the embedded controller.
I wish to perform the following:
Add one 18 GB drive and create a RAID 1 configuration with the existing 18GB drive.
Add an additional two 145GB drives and create a RAID 5 configuration with the 3 145GB drives.
I'm hoping to perform this without performing a server rebuild/restore as the existing 145GB is currently 95% full. Is this possible?
Can anyone provide some advice on the best way to perform this upgrade?
Thanks in advance for any feedback provided.
Cheers,
John

Re: Upgrade Embedded SCSI to RAID
if you are going to add Smart Array controller, the upgrade requires full rebuild/restore.

Re: Upgrade Embedded SCSI to RAID
Zygmunt,
Thanks for the prompt reply.
Given that I have approx. 140 GB of data to restore, I was hoping to avoid doing that.
Do you have any suggestions on how to perform this while avoding a restore? I know it's a longshot, but I would really like to avoid it.
Thanks,
John

Re: Upgrade Embedded SCSI to RAID
The data stays intact and online during the process.
Not the best solution cost wise, but that would be one of the only ways to do it without a restore. 140GB's should not take too long. What kind of media are you using for backup?

Re: Upgrade Embedded SCSI to RAID
That would only be possible if no Smart Array controller is used (i.e. all disks on the onboard SCSI controller and using Software RAID). You cannot migrate disks from SCSI to Smart Array without data loss. It's also not possible to split the disks in the drive cage between controllers.
Regards
Stephen

Re: Upgrade Embedded SCSI to RAID
All,
Thanks for the replies.
Steven C, I have purchased three additional 145GB drives and was planning to use one of them as a hot standby so copying the data sounds like a viable option. I'm using SDLT media for backup.
Since posting, I have pondered using Ghost to clone the 18GB drive once I've connected it to the RAID Controller and then using the method Steven mentioned to move the data across to the new RAID 5 set.
Can anyone comment on this method?
Thanks again for your input guys. It's greatly appreciated.
Cheers,
John

Re: Upgrade Embedded SCSI to RAID
I'm using Ghost software for more than 5 years for DR on the servers and it works very well on RAID1 or NoRAID volumes only, so for your 18gigs is perfect.
At the moment is not possible to do the same with RAID5 arrays, even I've read some posts about Acronis True Image 8 that seems make it possible...
Have to test it.
Even the Ghost 2003 can create images of dynamic partition/disks I suggest to do not update it if possible.
In any case please refer to the link for more info:

I hope that helps
