Hello ,
Thanks for reply.Method used in LUN Management with ZFCP: SLES
Post-Installation" pdf is YAST. But I am not able to find file name and
location, where I can manually modify the entry for new WWPN number.
Current output for some of the commands are
sles112 : :/ # lszfcp -D
Error: No fcp devices found.
sles112:/sys/bus/ccw/drivers/zfcp/0.0.651e # cd peer_wwpn
-bash: cd: peer_wwpn: Not a directory
sles112 :/ # lszfcp -Ha | grep -e port_name -e ^0
0.0.651e host0
permanent_port_name = "0xffffffffffffffff"
port_name = "0x0"
