P2000 with Multi Servers

I have to DL380p Gen 8 servers directly connected to a P2000 via 8gb fibre channel. When connecting to a LUN created on the P2000, it allows the LUN to be online on both servers. This creates file system issues, as the LUN can be written to from both servers. Is there a way to make it work like iSCSI? Where  the LUN can only be online on one server at a time, and if the LUN is brought online on one server, it automatically takes it offline on the other? I am just beginning with fibre channel and iSCSI, so pardon my noob-ness.

Re: P2000 with Multi Servers

This is a task of a volume manager or even the (shared) file system, not a task of the array itself.


Hope this helps!

Re: P2000 with Multi Servers

FC or iSCSI makes no difference.

 

You are basically describing a software cluster functionality/shared cluster volumes

 

The disk system won't prevent the servers who has been given access to work with the lun/disk and you will get data corruption on the disk.

 

A failover cluster can be old school Microsoft cluster or an active/active example can be a Vmware ESX cluster with a vmfs datastore. (A bit simplified but you get the idea)

Re: P2000 with Multi Servers

Make sure to remove Default volume mappings, Default mapping maps volume to all ports and hosts. You need to use EXPLICIT mappings in order to map each server to its own port on P2000. That will solve your problem.
