One emc powerpath failed
It seems like I lost one path on my Solaris-11 box. But I want to make sure before going to Storage team, if issue is from OS side or Storage side. Storage team is able to see that only one wwwn is looged in their switch. I am not at server's physical location. What does below output says ? I assume that if cable is defective or not connected, it should say "NOT CONNECTED". Why other path is not visible here ?
Code:
root@dbpautp02 # luxadm -e port
/devices/pci@400/pci@2/pci@0/pci@1/pci@0/pci@3/SUNW,emlxs@0/fp@0,0:devctl  CONNECTED
