Solution

1. QLogic Driver Update to the latest version 8.03.01.06.05.06-k
2. Before proceeding, be sure to take a copy of /etc/modprobe.conf
3. Remove entries associated to the " qla2xxx" in /etc/modprobe.conf
4. Add the entry " blacklist qla2xxx" at the end of the file /etc/modprobe.d/blacklist
5. Reboot the server "reboot"
6. lsmod|grep -i ql >> "Nothing reported"
7. /usr/openv/netbackup/bin/admincmd/nbftsrv_config -nbhba
8. /usr/openv/netbackup/bin/admincmd/nbhba -l
9. /usr/opemv/netbackup/bin/admincmd/nbhba -modify -wwn <XXXXXXXX> -mode target
10. /usr/opemv/netbackup/bin/admincmd/nbftsrv_config
11. replace the /etc/modprobe.conf with the copy saved in step 2
12. Remove the entry in the /etc/modprobe.d/blacklist
13. Reboot the server "reboot"

If still getting an error, check if HP Insight agents are running. If they are, you will not be able to unload the qla2xxx driver.

To check if the HP Insight package is loaded -

Use "/etc/init.d/hp-snmp-agents stop" to free the qla2xxx driver.

Once they have been stopped, run -

/usr/openv/netbackup/bin/admincmd/nbftsrv_config -nbhba

Applies To

Older version of FT Media Servers like Linux 5.x, for Linux 6.x and above does not have /etc/modprobe.conf and for that refer the article:
