Chapter 4. Configuring InfiniBand with QLogic bridges 51
To create virtual SRP interfaces on a Linux blade server, complete these steps:
1. Each bridge module has two IO Controllers (IOC). Find the SRP IOCs of your bridge
module by displaying the SRP driver information using the cat command as shown in
Figure 4-19. The driver file is located in the folder /proc/driver/ics_srp.
Figure 4-19 Displaying the SRP driver information
In Figure 4-19, the IOC numbers are 0x00066a01e000018c and 0x00066a02e000018c.
2. Open the SRP config file /etc/sysconfig/ics_srp.cfg in a text editor.
