8 Installation Requirements
3 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
4 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)
1 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
2 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 Step 1
.
• 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 2TB LUN Requirements
on page 11.
For assistance configuring the operating system file, contact ATAC. Refer to Customer
Assistance on page 97.
