Re: bl460c boot from san

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 ?

Re: bl460c boot from san

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

Re: bl460c boot from san

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

Re: bl460c boot from san

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

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 ?

Re: bl460c boot from san

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 .

Hi,

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