This section describes replacing an online host bus adapter (HBA) when DMP is managing multi-pathing in a Storage Foundation Cluster File System (SFCFS) 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:
To replace an online host bus adapter
Determine the hardware path or paths to be disabled on one of the nodes, which has a hotplug capability.

A single HBA may show as multiple controllers (c#
) in the vxdmpadm getctlr output. To replace the HBA, you must disable each of these controllers in step 3 and enable each of them in step 10.
# vxdmpadm disable ctrl=ctrl#
# vxdmpadm disable ctlr=c16
# /usr/bin/olrad -r slot_ID
The above command performs a Critical Resource Analysis (CRA).
# /usr/bin/olrad -q
# /usr/bin/olrad -R slot_ID
# /usr/bin/olrad -q slot_ID
