To use load balancing on an ATTO 8-Gbps HBA, you must enable
the Target Port Group Support (TPGS) host type.
SAN Volume Controller version
4.2 or later supports load balancing on Apple hosts when you specify
the TPGS host type.
To enable load balancing on Apple hosts with an 8-Gbps HBA
from ATTO Technology, perform the following steps:
- Change the SAN Volume Controller host
type from Generic to TPGS.
- Activate the new configuration by rebooting the Apple host.
- Verify that the new configuration is active by performing
the following steps:
- Run the ATTO Configuration Tool which is located 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 SAN Volume Controller node
for that LUN.
