when i booted from the firmware cd it boots and i installed but the real problem is not this

i press f9 and configure boot controller to boot from my hba

Set up switch zoning

Create a LUN i gave the first lun

press ctrl Q and i gave the two ports
four ports of wwwn of the eva
and then
i reboot and i start with linux askmethod and add qla2400
i see the hardrive but i see the harddrive for 8 times

i give / /boot /swap on sda and
install rh4-u4-x86_64-as and all package
reboot but it cant reboot
why?

why it cant reboot from san why

Did You even read this ?

Boot from SAN is not supported without some LINUX HACKING

Install RHEL 5.1 and You might get lucky.

Also.. what interconnects You have in Your blade enclosure ?

i read but i think the problem is different
i did the everything in this document
i read your document too

but i only install redhat and it says reboot after installation then then it cant reboot
okey now i am trying redhat 5 and we are going to see

[hturker]

and a question did you try that unix hack
how can hack while all the system is in san and while i cant reach them

[JKytsi · Accepted solution]

I don't have to try it because I know that is never gonna happen with RHEL4 unless You use only single path to LUN.

But If You could tell me what interconnects are used in the blade chassis .

[hturker]

now i am installing redhat5 u1
select drivers to use for ,installation and i see that there are 8 disks and all of them are same disk i choose sda and finish installation but when i reboot it didnot boot tooooo

brocade 4/24 san switch
and i have HP StorageWorks 4/256 SAN Director to eva 8000
my hba is qmh2432

i make zorning and i added 4 port from eva 2 port from blade

what is wrong this takes 3 days from me

Hi,

Do You know what multipathing means ? You have to configure your dm-multipath so your 8 disks "become one"
