3. View the modules loaded for the Qlogic HBA:
# /usr/sbin/esxcfg-module -g qla2xxx
qla2xxx enabled = 1 options = '' (currently there are no options set.)
4. Display the current Queue Depth for the Qlogic HBA:
# cat /proc/scsi/qla2xxx/4 | grep -i "queue depth"
Device queue depth = 0x20
5. Change the Queue Depth for the HBA to 64:
# esxcfg-module -s ql2xmaxqdepth=64 qla2xxx
6. Reboot the ESX server for the change to take effect:
NOTE: Ensure the ESXi server is in maintenance mode and all VMs are either vMotioned to another server or powered off.
# reboot
7. Display the current Queue Depth for the Qlogic HBA:
# cat /proc/scsi/qla2xxx/4 | grep -i "queue depth"
Device queue depth = 0x40
The queue depth has now been sucessfully changed for this HBA from 32 to 64.
ESXi 4.1 vSphere CLI Procedure to Change HBA Parameters
Identify the Qlogic driver Modules installed in your system.
C:\VMware\VMware vSphere CLI> vicfg-module.pl –l
(The following output was edited to only show the Qlogic modules)
Name ID Loaded
qla4xxx 36 Yes (iSCSI HBA driver)
qla2xxx 37 Yes (Fibre Channel HBA driver)
2. List the current options enabled for the Qlogic driver.
C:\VMware\VMware vSphere CLI> vicfg-module.pl –g qla2xxx
qla2xxx options = '' (currently there are no options set.)
3. Set the queue depth for the qla2xxx driver to 64.
C:\VMware\VMware vSphere CLI> vicfg-module.pl –s ql2xmaxqdepth=64 qla2xxx
No response is echoed.
4. Check the queue depth setting for the qla2xxx driver.
C:\VMware\VMware vSphere CLI> vicfg-module.pl -g qla2xxx
qla2xxx options = 'ql2xmaxqdepth=64'
Additional Common Parameter Examples:
vSphere CLI commands are shown in blue.
