Linux and Emulex fibre
 

Hi,

I have a centos 5.3 dell machine with emulex card. When I do : lsmod, I can see the lpfc module loaded. So, I assume my emulex card is working. Now I am not able to see the attached storage in dmesg and neither by fdisk -l. How do i trouble shoot to actually load the SAN storage allocated by my administrator.

do i need any extra tools to actually see the san storage zone in my machine?


I also tried to re-load the lpfc module and here is what i see in dmesg

It may not be zoned correctly, you might need to talk to your San admin and find out how many devices you should be seeing. Dont forget if you have 2 fibre cards you will see each device twice.
Also you might need to re-scan the scsi devices in order to find the disks.

re-scanning didn't help. followed this doc to re-scan

SAN is McDATA/Hitachi. My admin told me that the zone is properly created and works in solaris. But I don't know why it is not working in Linux.

Any inputs?

Thanks !

Check with your SAN admin to see if they can see the server login to the switch ?
Also their might be different disk configuration options for solaris and linux on the san which might also be why the server cannot see the disks (lun masking I think its called) Not sure just a few thoughts to try.
