If your adapter is qlogic, you can use sansurfer. There is a sansurfer "CLI" version for command line instead of graphic view.

If you HBA is emulex, then you can try with Emulex HBAs anywhere.

[Kevin Wright]

cat /proc/scsi//*
if using the psp, run adapter_info.

[skt_skt]

#lspci|grep -i fibre
04:04.0 Fibre Channel: QLogic Corp. QLA2312 Fibre Channel Adapter (rev 02)
09:02.0 Fibre Channel: QLogic Corp. QLA2312 Fibre Channel Adapter (rev 02)

Below will give more detailed info

# cat /proc/scsi/qla2300/[1-2]*

Thanks for you responses.

I tried all the above commands and it has not returned any value / information.

/usr/sbin/adapter_info
/sbin/lspci |grep -i fiber

under /proc/scsi i can find only these below files

cd /proc/scsi
ls -l
total 0
-r--r--r-- 1 root root 0 Nov 6 09:21 device_info
-r--r--r-- 1 root root 0 Nov 6 09:21 scsi
dr-xr-xr-x 2 root root 0 Nov 6 09:21 sg

cd sg
ls -l
-rw-r--r-- 1 root root 0 Nov 6 09:22 allow_dio
-r--r--r-- 1 root root 0 Nov 6 09:22 debug
-rw-r--r-- 1 root root 0 Nov 6 09:22 def_reserved_size
-r--r--r-- 1 root root 0 Nov 6 09:22 device_hdr
-r--r--r-- 1 root root 0 Nov 6 09:22 devices
-r--r--r-- 1 root root 0 Nov 6 09:22 device_strs
-r--r--r-- 1 root root 0 Nov 6 09:22 version

Please suggest.

Hi Jagadesh,

For some HBAs and new kernels you find the information under /sys instead of /proc:

for Emulex HBA and Kernel 2.6 you can try:
$ uname -r
2.6.16.46-0.12-smp

$ cd /sys/class/scsi_host/
$ cat host?/modeldesc
Emulex LPe11002 4Gb 2-port PCIe Fibre Channel Adapter
Emulex LPe11002 4Gb 2-port PCIe Fibre Channel Adapter
Emulex LPe1150 4Gb PCIe Fibre Channel Adapter

$ cat /host?/state
Link Up - Ready:
Fabric
Link Down

most likely you don't have hba's installed on this server then. adapter_info/lspci should show you the devices if they are installed.
