Create a new initial RAM disk file by using the mkinitrd command.

For example:

• For IA64: 

cd /boot/efi/efi/redhat

mkinitrd -f initrd-2.4.21-27.EL.img 2.4.21-27.EL

• For x86:

cd /boot

mkinitrd -f initrd-2.4.21-27.EL.img 2.4.21-27.EL

Reboot the machine.

SuSE Linux Prerequisites

Before installing StorNext on a SuSE Linux machine, verify that the following installation prerequisites 
have been met.

• Kernel Requirements - Before installing StorNext on a SuSE Linux machine (either client or 

server), verify that the required kernels are loaded: 2.6.5 - 7.191 (SP2); 2.6.5-7.244-SMP (SP3)

Run the rpm command. Type:

rpm -qf /boot/vmlinuz

The command output should display one of these kernels:

• For uniprocessor systems:

k_delft-2.6.5-7.191

• For multiprocessor systems:

k_smp-2.6.5-7.191

Do one of the following:

•

If the correct kernel is shown, continue with the installation.

•

If an incorrect kernel is shown, install the correct kernel and repeat 

.

• Mapping LUNs - Before installing StorNext, it is necessary to correctly map LUNs in the customer 

SAN. 

A LUN is assigned to each device (target) that is visible locally and over the SAN. The process 
of LUN mapping depends on many factors, including the operating system on which StorNext 
is running, the type of SCSI card installed on the machine, and the type of FC HBA installed 
on the machine. 

For each HBA, check the vendor documentation to determine the operating system files that 
must be configured to correctly map LUNs to devices over the SAN. Configure the operating 
system file as indicated below:

•

Edit  the  /etc/raw file and use the rpm and insmod commands to install the specific 
Fibre Channel HBA driver.

For additional requirements, see 

For assistance configuring the operating system file, contact ATAC. Refer to
