EMC Host Connectivity with QLogic FC and iSCSI HBAs and FCoE CNAs for the Linux Environment
Installing and Configuring the Linux Host with the QLogic Driver
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.
1. Boot into the qualified and supported kernel onto which the
driver will be installed.
2. Obtain the
qliscsi-linux-3.22-2-install.tgz package from
the EMC-approved section of the QLogic website listed 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-3.22-2-install.tgz
The initial uncompression will provide you with the following:
