Volume Logix is used to restrict access to particular WWPNs on the fabric for Symmetrix Volumes.
This function can be switched on and off by changing the VMC_State port setting. The Lenovo Storage V7000 requires that you do not share target ports between a host and a Lenovo Storage V7000. However, you can still use Volume Logix to protect the system from errors that can occur if the SAN is not correctly configured.
To mask a volume to the Lenovo Storage V7000, you must first identify the Lenovo Storage V7000 ports that are connected to each system. You can identify these ports using the EMC Symmetrix symmask command.
The Lenovo Storage V7000 automatically logs in to any EMC VMAX system that it sees on the fabric. You can use the Lenovo Storage V7000lsnode CLI command to find the correct port identifiers.
After you have identified the ports, you can map each volume on each port to each WWPN. The EMC VMAX stores the LUN masking in a database; so you must apply the changes that you have made to refresh the contents of the database to view the changes.
