Enable the Fibre Channel tutorial on Openfiler

As the server's IO starts to be slightly inadequate, a QLogic FC card needs to be installed to increase server and storage performance. This article describes the example

Where Openfiler 2.99 enables FC and creates target. (Note: Please replace the characters in <>)

1.unmap a volume, this step can be done through the Openfiler Web interface.

2. Enable FC Target in the service of the Web interface

3. Run the following command to enable Vdisk_fileio and Vdisk_blockio

The code is as follows	Copy Code
Modprobe Scst_disk Modprobe Scst_vdisk Modprobe qla2x00tgt Modprobe Scst_vdisk Modprobe Scst_user Modprobe Scst_modisk Modprobe Scst_processor Modprobe Scst_raid Modprobe Scst_tape Modprobe Scst_cdrom Modprobe Scst_changer Modprobe ib_srpt

4. Create a SCST device

The code is as follows	Copy Code
Scstadmin-open_dev <device-name>-handler <vdisk_fileio or vdisk_blockio>-attributes Filename=<path of Logical volume>

5. Create a security group for the server

The code is as follows	Copy Code
# Add Group Scstadmin-add_group <group-name>-driver qla2x00t-target <onboard FC card wwn> # Assign server FC to security group Scstadmin-add_init <server wwn>-driver qla2x00t-target <onboard FC card wwn>-group <group-name>

6. Assigning virtual disks to security groups and LUNs

The code is as follows	Copy Code
Scstadmin-add_lun 0-driver qla2x00t-target <onboard FC card wwn>-group <group-name>- Device <device-name>

7. Save the actions you just made to the config file

The code is as follows	Copy Code
Scstadmin-write_config/etc/scst.conf

After saving, the following information should be kept in the scst.conf:

The code is as follows	Copy Code
HANDLER Vdisk_fileio { DEVICE <device-name> { t10_dev_id "Fc_vol 3d61d0df" USN 3D61D0DF Filename/dev/group_1/logical_volumn_1 } } Target_driver qla2x00t { TARGET <onboard FC Wwn 1> { REL_TGT_ID 1 Enabled 0 } TARGET <onboard FC Wwn 2> { REL_TGT_ID 2 Enabled 1 GROUP <group-name> { LUN 0 <device-name> Initiator <server FC Wwn> } } }

In fact, this configuration file can be modified at will, as needed, you can run the following command to make it effective

The code is as follows	Copy Code
Scstadmin-config/etc/scst.conf
