Fabric Configurations
Obtaining Information Needed to Configure Persistent Binding
To obtain all information necessary to configure persistent binding,
the system osmlog must be configured to accept the output of the
qla2200 driver. The driver must then be configured to output
information to the osmlog.
Increasing osmlog
Buffer Size
Setup Checklist step 9a
The osmlog is a file containing all messages displayed at boot time.
The osm file size is limited by the buffer space available at boot time.
To ensure that all information is output to the osmlog properly,
perform these steps:
1. Type
cd /etc/conf/mtune.d ENTER.
2. Edit the file util and change the line containing
PUTBUFSZ to the
following:
PUTBUFSZ 2000 2000 60000
3. Type cd /etc/conf/bin ENTER.
4. Type
./idtune PUTBUFSZ 60000 ENTER.
5. Type
./idbuild -B ENTER.
6. Type
./idcpunix ENTER.
7. Next:
• If qla2200/space.c is already configured with
qlc2200_enable_output_binding = 1, reboot.
• If qla2200/space.c has not been modified, go to Configuring the
Driver to Output Persistent Binding Information on page 36.
