Chapter 3 Configuring the New Devices
After 9900V installation and connection are complete, the devices on the 9900V subsystem
are ready to be configured for use. Configuration of the 9900V devices is performed by the
user and requires superuser/root access to the host system. The activities involved in 9900V
device configuration are:
Setting the number of Logical Units (see section 3.1).
Partitioning the disk devices (see section 3.2).
Creating, mounting and verifying the file systems (if necessary) for the disk devices (see
section 3.3).
3.1 Set the Number of Logical Units
Important: The 9900V supports up to 16 logical units per fibre-channel port, but only supports
a maximum of 16 LUNs in one system. If there are other devices with different host
adapters, the number of available LUNs will be reduced accordingly.
To set the number of LUs, you need to edit the lilo.conf file as follows:
image=/boot/vmlinuz-qla2x00
label=Linux-qla2x00
append="max_scsi_luns=16"
root=/dev/sda7
read-only
#sbin/lilo
