DL560 MSA30 drive array Hard drive upgrade to 146GB 15k drives

I have two DL560 servers with 6402 controllers (firmware 2.34) with a MSA30 attached to each server with a mixture of 15k and 10drives.

One server is a 4 cpu 2.8ghz SQL server

One server is a 2Ghz DATA server

The problem I have is that I would like to upgrade all the drives in SQL DL560 MSA30 drive array with 146GB 15k drives

I would like to implement this with some form of role back plane.

My plane is to use one of the servers to restore the data

I would like to temporally remove all the drives form my DATA server. And install the new 14 drive into the data server.

Backup the SQL server and restore onto the DATA servers new drives. Verify that the restore has been successful, and move the 14 new drives from the data server to the SQL server.

Re-install the DATA server drives.

Could you tell me the best way to carry out the above procedure. Will I have to backup and restore the 6402 configuration. At each change of hardware configuration. Or will I just have to reboot the server at each stage in the process.

Or has anyone one have a simple solution to my upgrade problem

The server is MS 2003

Fabain:


WHat do you mean by role back plan? You want to be able to go back to the mix of drives you currently have? or you just want a backup recovery stratagy?

Possibly, the simplest way to get your array to have all new 146GB 15k drives is to replace each existing drives one by one. I.E. pop a drive out, replace it with the new and wait for it to rebuild. Once rebuild, start the second one and continue the process.

After you replace all the drive, you should be able to increase the size of your logical drives and then eventually your OS partitions. If your running Windows, it is a very easy process and can be done usually without any downtime.

Within windows, all the tools you need are the ACU and diskpart.exe from the Windows Resource Kit (if your running Windows 2000). I believe it is part of the standrad files in Windows 2003.


As for doing it the way you laid out... It is possible. You should not have to back up any SA configu as the config is stored on the drives themselves. Once you replace the original set with the new set, the 6402 should say... "hmm... new drives... with a config... nice... let's spin them up".

Many thanks for your help

My main reason for the role back plan is that restore time from tape is 8 hours plus. So if I can find some way of upgrading without making any changes to the data on the old dives

Hi all!

Steven suggested the good plan with minimal risk of corruption data and continiouos proccessing data...

BUT

Fabian, note that the rebuild process can take a lot of time and decrease perfomance (in case when high rebuild option enabled)in production enviroment. What your current RAID level? Do you have BBWC option on your RAID-controller? It can greatly increase rebuild perfomance.
