Emulex Fibre ??

We have an Emulex LP10000-E fibre card installed and running Red Hat 5.3 x86_64 OS..

I cannot see the LUN's on the EMC SAN, but everyone says it is all working correctly, except on the server...

dmesg | grep -i emulex
Emulex LightPulse Fibre Channel SCSI driver 8.2.0.33.3p
Copyright(c) 2004-2008 Emulex. All rights reserved.

I know on HP-UX I have the fcmsutil command available to check it's status but on Linux I am at a loss right now... Everyone telling me it's the server but don't know how to check anything on the server...

Can anyone give some direction....

Thanks

Re: Emulex Fibre ??

You could use HBAanywhere to diagnose your problem and identify if you can see the devices.

If you have hp_fibreutils package, run hp_rescan -a command. Also, run lssd and lssg.

Install proliand support pack if this is a proliant server.

Re: Emulex Fibre ??

Is there a x86 64bit Red hat version of HBAanywhere ?

Can't locate the download if there is one...

Re: Emulex Fibre ??

I was able to get the HBAnywhere installed and I ran it's lun_scan but I am not seeing any LUN's on the SAN..

# /usr/sbin/lpfc/lun_scan all
Scanning lpfc HBA instance with scsi host number : 3
Scanning lpfc HBA instance with scsi host number : 4

Re: Emulex Fibre ??

I never used EMulex HBAs, I don't know if the command should display new detected devices. After running the command, do you see any new ouput running fdisk -l?

No, only my internal disk that the OS is installed on...

Re: Emulex Fibre ??

Are you sure that the SAN Switch zoning is correctly configured, your HBA is correctly connected, and the devices are presented?

¿Can the storage administrator see the host WWN and confirm that is online?

Re: Emulex Fibre ??

The cause ended up being the fibre cables were switched into the server so the WWN's were not resolving on the correct ports...
