Symmetrix Fibre Channel with Qlogic HBAs on UnixWare 7
Fabric Configurations
Configuring and
Enabling Persistent
Binding
Setup Checklist step 11
After a reboot with a larger buffer size for the osmlog and the
variable qlc2200_enable_output_binding set to 1, all information
needed to configure persistent binding will be in /var/adm/osmlog.
Configuring Persistent
Binding
Setup Checklist step 11a
In the osmlog, after a list of all Symmetrix devices seen by the host,
you should see Notice lines output by the qla2200 driver, similar to
the example below.
Example: The following is an example of part of qla2200 driver output to the
osmlog:
The first two lines refer to the WWN of the Qlogic HBA. All lines
with
scsi-qla2-device and scsi-qla3-device are Symmetix
ports. Each Symmetrix port WWN must be entered into the structure
binding_info_t_qlc2200_binding_info found in the file
/etc/conf/pack.d/qlc2200/space.c.
The following is a properly configured qlc2200 binding_info structure
from the above osmlog output:
After the persistent binding structure is filled in properly, the variable
char qlc2200_enable_binding must be set to 1. This will tell the
driver to look at the structure for persistent binding order.
