Installing and Configuring the Linux Host with the QLogic Driver
This method requires no manual edits for systems attached to
EMC storage arrays. By installing the QLogic RPM, the necessary
files will be edited and the driver will be compiled and installed
automatically.
Note: Refer to “Installing QLogic v3.x-Series iSCSI driver via the QLogic
installation script, Method two” on page 101.
Installing QLogic v3.x-Series iSCSI driver via the QLogic DKMS RPM, Method one
This section guides you through the process of installing and utilizing
the DKMS RPM on RHEL 3.0 Dell systems. The DKMS RPM will
build and install the
qla4010.o driver and will modify the
/etc/modules.conf file.
In the
/etc/modules.conf file, the hostadapter line for the qla4010
driver will be appended. The
options line containing the addition of
the
scsi_allow_ghost_devices and max_scsi_luns parameters
will also be appended to the file. This will allow the host to correctly
identify-the disconnected LUN 0 that is reported when attached to
VNX series or CLARiiON storage systems as well as allow the SCSI
stack to scan up to 255 devices.
Note: The Unisphere/Navisphere Host Agent requires that the disconnected
LUN 0 be reported.
The DKMS RPM will create the QLogic v3.x-series driver as a
module.
Follow these steps to integrate the QLogic driver into RHEL 3.0 hosts:
1. Boot into the qualified and supported kernel onto which the
driver will be installed.
2. Obtain the
qliscsi-linux-3.22-1dkms.tar.gz package from
EMC-approved section of the QLogic website as instructed in
“Downloading the QLogic v3.x-Series iSCSI driver for the v2.4.x
kernel” on page 98.
3. Uncompress and extract the source files from the tar archive:
tar zxvf qliscsi-linux-3.22-1dkms.tar.gz
The initial decompression will provide you with the following:
qliscsi-linux-3.22-1dkms/
qliscsi-linux-3.22-1dkms qla4xxx-v3.22-1dkms.noarch.rpm
qliscsi-linux-3.22-1dkms/dkms-2.0.5-1.noarch.rpm
