LUN and Storage Group mapping rule for EMC VNX SAN Storage

emcvnx

LUN and Storage Group mapping rule for EMC VNX  SAN Storage

Product:

CLARiiON AX Series, CLARiiON CX Series,CLARiiON iSCSI Array, VNX, VNXe.

Description:

The rule is that multiple hosts can access one Storage Group, but one host cannot access multiple Storage Groups.

1- One Host can be member of one Storage Group at one time ,it can not be member of multiple storage    group

2- One LUN can be member of Multiple Storage Group at same time .

3- You can not connect one storage group to multiple HOST  which is already connected to another storage group. this will create LUN connection fluctuation and disconnection.

 

Resolution:

For high availability, a server can connect to only one Storage Group per storage system at a time. If you connect a server that already connects to a Storage Group to another Storage Group, the server will disconnect from the first Storage Group. When disconnect a server from a Storage Group, and then connect it to a different Storage Group, the server can no longer perform I/O to the first Storage Group.
