Some question about the Lefthand

Some question about the Lefthand

Dear all:
I have three Lefthand P4300 storage system.
And I have some question about it.
1.What will happen if I make a mistake to use an exist iqn to create a new server.
2.I create an 100GB volume which provisioning type is thin and assign it to three host.
What's the assign relation of this volume for these three host?
Whether the capacity of these three host reach to the 100GB that none of them can write more data to the volume?
Is there any way to control it such as the quota.

Thanks & Best Regards

Re: Some question about the Lefthand

Your question is that clear, not sure what you mean by point 1.

Question 2 You should only assign the same volume to operating systems that support clustered file systems, such as VMware ESX. The capacity is at the volume level. It would not make any differnence to the number of hosts assigned to it.

Thanks dears.
I mean that I had already create an server(server1) by use an iqn(iqn1).What will happen If I make a mistake to use the same iqn(iqn1)to create another server(server2).Whether the system will tell you that the iqn has already exist.

Thanks & Best regards

Re: Some question about the Lefthand

Answer 1 : If you have already created a Sserver in CMC with a particular IQN, then CMC will not allow you to create another Server with the same IQN.

Answer 2: If you are providing Read/Write Access to more than 1 Hosts/Servers, then they need to in a Cluster Configuration.
They need to be part of Windows/Linux/ESX Cluster.

Else there would be data corruption.

There is no Assign relationship/Quotas for Volumes that one can specify on the SAN Side.

If the 3 Hosts/Servers are in a Cluster they see the same volume and you should be able to know how much space is used from within the Operating System.
