Method used to modify the number of concurrent disks by using Fibre Channel HBA in Linux

You can perform the following operations to modify the number of concurrent disks by using Fibre Channel HBA in Linux:
The procedures are as follows (QLogic HBA is used as an example):
1. Query whether the host is installed with Fibre Channel HBA and query the HBA manufacturer. Run the lspci |grep "Fibre Channel" command to query HBA information.
2. Modify the configuration file. Run vi to open the /etc/modprobe.conf file and modify or add the parameter of concurrent HBA. Note: Modify the /etc/modprobe.conf.local file in SUSE and do not modify the /etc/modprobe.conf file.
3. Run the multipathing command upUpdate. If the actual operating system and hardware are different, the information to be displayed may also be different.
4. Run the reboot command to restart the host.
5. Run the lsscsi -l command to check whether the parameter of concurrent HBA takes effect.
