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.
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.
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
