Raid Group- Per Raid Type we pck the drives and make them a group.
Bind LUN-Create a logical LUN, specify LUN Size, Create LUN ID.
Storage Group(Access Logix)-Specify Which Specific Host accesses the Specific LUN.
CLARiiON: Enabling Access Logix
Access Logix software allows you to manage CLARiiON Storage Groups and connected servers, which you can do through the ControlCenter Console. Ensure that Access Logix is enabled on each CLARiiON array you want to manage. If Access Logix is not enabled, you can enable it from the ControlCenter Console.
To enable Access Logix from the Console:
Explore the CLARiiON arrays.
Right-click the CLARiiON array on which you want to enable Access Logix and select Enable Access Logix. If Access Logix is already enabled on the selected CLARiiON array, an information message appears.
For Solaris hosts that are connected to the CLARiiON array and running the Host Agent for Solaris, make sure that Access Logix's Unit Serial Number (USN) is set to Array. If the USN is set to LUN, the ControlCenter Console will incorrectly display the CLARiiON array being managed (each device on the array will appear as an individual array in the Agents view of the Console). If the Solaris host is also running Sun Cluster software, then you must set the USN to LUN. You set the USN through Navisphere CLI. See your Navisphere CLI, Access Logix, and Sun Cluster software documentation for more information.
You must have administrator privileges to enable Access Logix.
If Access Logix fails to run after enabling it through the Console, ensure that Access Logix is installed properly. See your CLARiiON and Access Logix documentation.
Masking is enabled or disabled on each EMC CLARiiON storage array by enabling or disabling the Access Logix software. Make sure that Access Logix is enabled on all CLARiiON storage arrays for which you want to control host access.
Before a host can be bound to a CLARiiON storage group, the host HBA must be registered with the CLARiiON storage port on which the storage group resides.
Masking CLARiiON storage arrays is performed in user-defined storage groups created on the CLARiiON array itself. Host access is granted and removed by adding and removing LUNs to and from the storage group, and then binding and unbinding hosts to the same storage group. Storage group management actions are typically created in the CLARiiON Storage Group Configuration wizard, then assigned to a task list, and sent to the ECC Server for execution.
CLARiiON is Active/Passive-If Storage Processor B fails then Storage Processor tresspasses to Storage Processor A usually by configuration or can be done manually from Navisphere or Navcli.
Symmetrix is Passive/Passive.
A LUN can be available in Multiple Storage Groups.
A Host cannot be available n Multiple Storage Groups.
Multple Hosts can be present in one Storage Group
New CLARiiON array cannot be seen by the Host if Access Logix is installed on the Array.
Raid Level Supported by CLARiiON 0,1,1/0,3,5,6.
