Hi,
Does Your OS version support boot from SAN ?
Does it support it via multiple paths (EVA8k has eight of them) ?

Are You using virtual connect or brocade switches in the blade enclosure ?

[JKytsi]

for example some googling

http://www.tuxyturvy.com/blog/index.php?/archives/42-RHEL4-dm-multipath-on-root-HOWTO.html

although it's made with IBM blades =)

bottomline root volumes are not supported over dm-multipath

[hturker]

my opareting system is redhat 4 update 4 2.6.19
i think it supports
i install os to the eva 8000
but it cant reboot from eva800
they said that update qlogic

but while there is no operating system how can i install it

[JKytsi]

It's a DOS boot disk. Mount it with virtual media. OR download new FW maintance CD. It will update your Qlogic too.

the fw cd does not contain this update sorry
now i downlaod the driver files from the link that i give and make an iso from them then upload from ilo as a virtual media
and restart the machine
but it didnot enter dos

[JKytsi]

Here is the link to DOS version

[hturker]

the driver software is in here

[JKytsi]

Well ...If You could take closer look on the link I pasted You find it to be same.

[hturker]

Here is the link to DOS version
yo said
but when i give that path to virtual media it cant open dos from there

how can i open that
say this.

[hturker]

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?

it supports eva8000 and ql2432
why it cant reboot from san why

have you got any idea

[hturker]

it comes attempting boot from hard drive c:
waits and waits

[JKytsi]

Did You even read this ?

OWTO.html

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 ?

[hturker]

http://h20000.www2.hp.com/bc/docs/support/SupportManual/c00166137/c00166137.pdf

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

[hturker]

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

[JKytsi]

Hi,

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

[hturker]

how can i configure my dm-multipath ?

[hturker]

while the operating system is in eva while i cant reach it

[JKytsi]

Plz try to install the OS via only ONE path.

[hturker]

now i am trying that but in zone config
it has four path :)
and in zone i dont want to change 4 path to one
i only disable one port of hba from ctrl q
i am try,ng now

[hturker]

eva 8k has four path
