III. QLA2100F SOLARIS X86 DRIVER ISSUES

The only known driver issue is related to a hub configuration. In a hubless or

hub

configuration the qla2100 driver 2.20 is designed to have an option of holding

I/O

indefinitely in the case the link is broken to the Symmetrix or the Symmetrix FA

goes offline.

In the Hub environment, the only exception to this is if one port of the

symmetrix is

offline and then another port on a hub configuration link is broken. This will

send a

Loop initialization primitive sequence around the loop which the driver

interprets

as the Symmetrix being back online which will initiate the qla2100 driver to

start

executing and returning all holding commands.

1. HOST DRIVER CONFIGURATION VARIABLES

The following variables are found in the file /kernel/drv/qla2100.conf. The

proper setting for driver configuration is crucial to Symmetrix and host

integration.

Each HBA has its own settings for each of the 17 variables in the

/kernel/drv/qla2100.conf file. (For example, if there are three QLA2100F

HBAs installed, a variable must be created for each HBA.)

Example In the example below, a separate variable line is dedicated to

each HBA (hba0, hba1, and hba2).

# Adapter hard loop ID enable.

# 0 = disable, 1 = enabled

hba0-enable-adapter-hard-loop-ID=1;

hba1-enable-adapter-hard-loop-ID=1;

hba2-enable-adapter-hard-loop-ID=1;

# Adapter hard loop ID.

# Range: 0 - 126

hba0-adapter-hard-loop-ID=125;

hba1-adapter-hard-loop-ID=125;

hba2-adapter-hard-loop-ID=125;

Note: Using the same hard loop ID for all HBAs is a valid configuration only in

a hubless loop connection.

Each HBA variable line in the qla2100.conf file corresponds to the instance

number of the HBA in the /var/adm/messages file. In the above example, hba0

of hba0-enable-adapter-hard-loop-ID=1 corresponds to instance #0 in the

/var/adm/messages file.
