Configure Queue Depth on multiple HBA's

Hello,

in our environment we have 2 server types (both vSphere 4.1 Update 1).

One type has 2 Dual-Port Qlogic HBA's, the other 2 Dual-Port Emulex HBA's.

Now we want to set the Queue Depth option for every hba (hba instance) to 64.

We've found the articles http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1267 and http://www.vmware.com/pdf/vi3_35_25_npiv_config.pdf.

Is it right that we must configure our Emulex hba's in this way:

esxcfg-module -s "lpfc8_lun_queue_depth=64 lpfc9_lun_queue_depth=64 lpfc10_lun_queue_depth=64 lpfc11_lun_queue_depth=64" lpfc820

where 8-11 are the instances we see under /proc/scsi/lpfc820 ?

What is with the Qlogic hba's ? In the article is only the command "esxcfg-module -s ql2xmaxqdepth=64 qla2xxx" mentioned. Are all instances of the qlogic affected from this command or is the "x" by "ql2x" a wildcard ?

Under /proc/scsi/qla2xxx we see instances with the numbers 7-10.

Yours sincerely

Sven
