Hi,

I would like to scan the SAN diskspace on one of the company's RH Server. I can see that 2 Emulex Lightpulse FC has been installed before. But I am not sure whether the correct driver has been installed by the previous admin. From Emulex manual, it says I should see 2 HBA cards when I do lpfcutil LISTPATHS but I don't see anything. When I do lsmod, I can see lpfc but it is not being used (please see attachments). I also tried /usr/sbin/hbanywhere but it says module not installed So now, I am lost on how I will rescan the disks without doing a reboot.

I have also tried the below:

Try the following commands

--To list hba info
#systool -av -c fc_host

--To scan new disk
#echo "- - -" > /sys/class/scsi_host/host#/scan

but /sys doesn't even exist.

The 'unknown device' indicates you may need to update your pci-ids - http://pciids.sourceforge.net/

Try that first then get back to us...

cheers

Hi kbp,

It seems to me that this will just give a specific name to the unknown device? Will this resolve my problem in rescanning the disk as well?

If so, what command should I key in?

Thanks.

If the device is unknown it may not initialise correctly or at all

Hi kbp,

Thanks. After I install pciids, how do i rescan the disks?

What does 'lspci' show now ? .. also what version of RH are you running ?
