To use load balancing on an ATTO 8-Gbps HBA, you must enable
the Target Port Group Support (TPGS) host type.
To enable load balancing on Apple hosts with an 8-Gbps HBA from ATTO Technology, complete
the following steps:
- Change the Lenovo Storage V7000 system host type
from Generic to TPGS.
- Activate the new configuration by rebooting the Apple host.
- Verify that the new configuration is active by completing the following steps:
- Run the ATTO Configuration tool, which is in the ATTO Configuration Tool
folder for the Applications folder.
- Verify that all the 2145 paths are shown as Preferred/Mixed
for Read- and Write-Mode.
- Verify that the paths per LUN show up as Preferred or Alternate, which
depends on the preferred system node for that LUN.
