HBA WWN PROBLEM

[mahalingam1]

Hi all

I have the following problem with a FC during executing a backup:

When i doing a heavy backup i get the following output in /var/adm/messages:

scsi: [ID 107833 kern.warning] WARNING: /pci@13c,600000/SUNW,qlc@1/fp@0,0/st@w2100001086122290,1 (st68)

SCSI transport failed: reason 'timeout': giving up



This warning appear on all storage nodes of legato with the same wwn.

I have located the HAB port in question:


luxadm -e port

Found path to 5 HBA ports

/devices/pci@1c,600000/SUNW,qlc@1/fp@0,0:devctl CONNECTED
/devices/pci@3c,600000/SUNW,qlc@1/fp@0,0:devctl CONNECTED

On the library side:


inquire

scsidev@9.0.0:HP Ultrium 2-SCSI F49Z|Tape
S/N: HUP5C00KS2
ATNN=HP Ultrium 2-SCSI HUP5C00KS2

S/N: HUP7A06CSQ

My question is how can i relate the HBA WWN on the server with the drive WWN on the library??

Thanks in advance and regards

I tend to use these commands:
luxadm probe
luxadm display <path-to-tape> # eg /dev/rmt/0n from 'probe' output


I hope that helps.
