Lun mapping to two igroups with two different HBA's
2016-04-24 11:56 AM
It's been a while since last time when I worked on FC.
I have 2 nodes HA, in cmod, the host has two HBAs and connect to to different switches, 2 FC ports on each node are connected to two diff switches.
Lets say i have a linux host with two HBA's ports, then I should create wo igroups
igroup create -f -t linux host1_hba0 [Qlogic WWPN Port 1]
igroup create -f -t linux host1_hba1 [Qlogic WWPN Port 2]
assuming I have a lun: /vol/vol1/lun1
the question is, should I map the lun to these two igroup's:
lun map /vol/vol1/lun1 igroup_host1_hba0
lun map /vol/vol/1/lun1 igroup_host1_hba1
