This section contains the procedure to replace an online host bus adapter (HBA) when DMP is managing multi-pathing in a Cluster File System (CFS) cluster. The HBA World Wide Port Name (WWPN) changes when the HBA is replaced. Following are the prerequisites to replace an online host bus adapter:
A single node or two or more node CFS or RAC cluster.
I/O running on CFS file system.
An M5000 server with at least two HBAs in separate PCIe slots and recommended Solaris patch level for HBA replacement.
To replace an online host bus adapter on an M5000 server

To identify the HBA, enter the following:
# cfgadm -al | grep -i fibre iou#0-pci#1 fibre/hp connected configured ok iou#0-pci#4 fibre/hp connected configured ok
To list all HBAs, enter the following:
# luxadm -e port /devices/pci@0,600000/pci@0/pci@9/SUNW,emlxs@0/fp@0,0:devctl NOT CONNECTED /devices/pci@0,600000/pci@0/pci@9/SUNW,emlxs@0,1/fp@0,0:devctl CONNECTED /devices/pci@3,700000/SUNW,emlxs@0/fp@0,0:devctl NOT CONNECTED /devices/pci@3,700000/SUNW,emlxs@0,1/fp@0,0:devctl CONNECTED
To select the HBA to dump the portap and get the WWPN, enter the following:
# luxadm -e dump_map /devices/pci@0,600000/pci@0/pci@9/SUNW,emlxs@0,1/ fp@0,0:devctl 0 304700 0 203600a0b847900c 200600a0b847900c 0x0 (Disk device) 1 30a800 0 20220002ac00065f 2ff70002ac00065f 0x0 (Disk device) 2 30a900 0 21220002ac00065f 2ff70002ac00065f 0x0 (Disk device) 3 560500 0 10000000c97c3c2f 20000000c97c3c2f 0x1f (Unknown Type) 4 560700 0 10000000c97c9557 20000000c97c9557 0x1f (Unknown Type) 5 560b00 0 10000000c97c34b5 20000000c97c34b5 0x1f (Unknown Type) 6 560900 0 10000000c973149f 20000000c973149f 0x1f (Unknown Type,Host Bus Adapter)
Alternately, you can run the fcinfo hba-port Solaris command to get the WWPN(s) for the HBA ports.
# vxdmpadm disable ctrl=ctrl#
# cfgadm -c unconfigure iou#0-pci#1
Look for console messages to check if the cfgadm command is unsuccessful. If the cfgadm command is unsuccessful, proceed to troubleshooting using the server hardware documentation. Check the Solaris 10 patch level recommended for dynamic reconfiguration operations and contact SUN support for further assistance.
