HP 3PAR VMware ESX Implementation Guide

4. Identify the QLogic HBA module currently loaded.
vmkload_mod -l | grep qla2300
5. The target port queue depth can now be modified via the service console command line using
VMware supplied binaries.
Depending on the model of the HBA, the module can be one of the following:
qla2300_707 (ESX 3.0.x)
qla2300_707_vmw (ESX 3.5)
The example shows the qla2300_707 module. Use the appropriate module based on the
result of the previous step.
The server must now be rebooted for the changes to take effect.
esxcfg-module -s ql2xmaxqdepth=42 qla2300_707
esxcfg-boot –b
6. Reboot the ESX host.
Upon booting, the ESX host will now be throttled to a maximum of 42 outstanding commands
(as per the example in Step 5) to the target (HP 3PAR StoreServ Storage port).
NOTE: For additional information on changing the queue depth for HBAs, see the VMware
Fibre Channel SAN Configuration Guide.
