Recover MSA60

Dear Experts

Our MSA60 is down due to one disk fail, now I got a new disk and plugg it in to MSA60, i need to reboot the server to make the SAN recover, now i need to ask is how long time will the recover process take? Its a raid 5+0 config and 750GB disks SATA 7200RPM and 12 of those disks in MSA60.

Thx for the answer

4GB/hour is an often quoted figure although it's probably more like 10GB/h, but it really depends on the amount of I/O from the users as it's a background task. You can change the rebuild priority using the array configuration utility.

You shouldn't have to reboot though, a Smart Array Controller should automatically rebuild, the ACU will give you an indication as to whether it's doing that or not.

By the way, it's DAS, not SAN.

Ya you are right its DAS, the problem was I powered off the MSA60 and now I powered on the server need to reboot the server to get the DAS working again, otherwise the server can not recognize the DAS.

Pity you turned the MSA off but that's done now. Powercycling the server shouldn't take more than a few minutes, you shouldn't have to wait for rebuild to complete before you can access the data although it will be a bit slower than normal until rebuilding is complete.

I hope the rebuilding MSA shouldn´t stop the server from booting, the OS is in the lokal disk, Im just worrying IF it happens.

I don't see why you would have problems, the only problem that occurs normally is it won't accept the replacement disk if it's added when powered off, but that's only if it's second hand with data on it - the controller will disable the array by default if that's the case as it doesn't want to overwrite it.
