Understanding Array building - Help

[Dan_394]

Hi,

I've got an MSA 2012sa with about 12 TB of disk space. When I configured an raid level 6 it asked me whether I want the array to be online or offline, I chose online. Right now the array is building and it says that because it is online I can start using it. However when I boot up my dl380 g6 server it can see the msa 2012sa, but can't see the array I created. So my question is what does being online and ready mean if I can't see it on the server?

Thanks
Dan

you have to present the volume to the server.
you can do this through the volume management section.

how it is attached to the MSA?

SAN switches? FC? SCSI?

while creating the lun, didn't ask to presento to a server or all?

That's a SAS interface array. Some information is needed about the connection between server and array (server SAS interface controller, direct connection, etc) as well as LUN security settings (presentation).

Hi Diego,

You're a star!. I didn't realise that I had to map it.

Now that I've mapped it is there a way for rhel 5.2 to pck up the partition while booted up?

Thanks
