In order to connect ESX3.0 to the SAN, the IBM blade server HS20’s HBA bios, and driver needs to be EMC approved, and have the PowerPath installed.
Although in the BIOS it says it is a QLogic 2310 HBA, however, in QLogic’s website, there is no driver for 2310. It is weird. And further shows that it is a QLogic 2340 made for IBM.
[root@bdc1esxv1 byron]# rpm -ivh qla2x00-v7.03.00-2.i686.rpm
Add these two lines:
alias scsi_hostadapter2 qla2300_conf to /etc/modules.conf
alias scsi_hostadapter3 qla2300 to /etc/modules.conf
Manually edit /etc/modules.conf to add this line:
options qla2300 ConfigRequired=0 ql2xfailover=0
Want to check if the driver for QLogic HBA has been installed? Open and take a look at the file /proc/modules:
qla2300_conf 301624 0 (autoclean)
sg 36612 0 (autoclean)
loop 12432 0 (autoclean)
