[SOLVED] Detecting WWID number of HBA on SLES11

shashij · 07-02-2010, 01:58 PM

Hi,

I have SLES11 installed on server. I have attached 2 SAS cables which are connected to External storage device.
I have connected 3 machines to external storage device. It shows total 6 ID’s. I want to know which 2 are from which machine.

I would like to find out the WWID number of HBA’s on SLES 11 machine.

Any idea; how can do this?

Thanks,
Shashank

cd /proc/scsi
Look for information on your HBAs (e.g. there will be qla2xxx/1 and qla2xxx2 for first two Qlogic 2340 HBAs). Cat those files and they'll give you a wealth of detail including "FC Port" information.

Also cat of /proc/scsi/scsi will show you information about SCSI devices detected including the disks over the SAN.

Thanks for reply.

I am serching for number similar to 500605b001415094 on server side. I see 6 numbers like ablove on storage device.

I think that 500605b001415094 is WWID.

How can I serch which 2 number (like 500605b001415094) belongs to any machine?

Thanks and Regards,

You have to look at the /proc/scsi info as I mentioned.

What do you see when you type "ls /proc/scsi" on the servers?

For example on one of my servers I see:

Code:

# ls -l /proc/scsi

total 0
-r--r--r-- 1 root root 0 Jul  2 15:30 device_info
dr-xr-xr-x 2 root root 0 Jul  2 15:29 qla2xxx
-r--r--r-- 1 root root 0 Jul  2 15:30 scsi
dr-xr-xr-x 2 root root 0 Jul  2 15:30 sg

If I then cd to /proc/scsi/qla2xx and do the ls -l I see:

Code:

# ls -l

total 0
-rw-r--r-- 1 root root 0 Jul  2 15:31 1
-rw-r--r-- 1 root root 0 Jul  2 15:31 2

If I then cat out the contents of 1 I see:

Code:

# cat 1

If I did the cat on 2 it would give me slightly different information. The information should be in the ...target and ...port lines.

The above is for Qlogic. For Emulex I don't know what it would be but is should have some sort of information in /proc/scsi.

Hi,

ctl1:/proc/scsi/mptsas # cat 1
ioc1: LSISAS1068E B3, FwRev=011b5200h, Ports=1, MaxQ=277
ctl1:/proc/scsi/mptsas # cat 2
ioc2: LSISAS1068E B3, FwRev=011b5600h, Ports=1, MaxQ=277
ctl1:/proc/scsi/mptsas #

These 2 are HBA's on my machine. But I not able to find WWID number till now.

Help is much appreciated.

Thanks and Regards,

shashij · 07-02-2010, 05:41 PM

Hi,

I could find the WWID of HBA's. It is manual process to see the exact number, but I am not blocked now.

cpt2:~ # find /sys -name sas_address

It gives lot of files. I went thr each file and could match the wwid that is available on storage.
e.g:
cpt2 #cat /sys/devices/pci0000:00/0000:00:07.0/0000:1a:00.0/host1/phy-1:3/sas_phy/phy-1:3/sas_address
0x500605b001413460
cpt2 #

Thanks all for help.
