The procedure for changing the queue depth of a HBA on vSphere ESXi servers differs a little bit from vSphere ESX servers. For ESXi you can performe this procedure from the vSphere CLI or the vSphere Management Assistant (vMA).
The following example describes the procedure for changing the queue depth for a QLogic adapter:
- Verify which QLogic HBA module is currently loaded by entering the following command:esxcfg-module -list | grep qla
- Run the following commands. The example shows the qla2xxx module. Use the appropriate module based on the outcome of the previous step.vicfg-module -s ql2xmaxqdepth=64 qla2xxx
In this case, the HBA represented by qla2xxx will have its LUN queue depth set to 64.
- Reboot your host.
