Before you replace a host bus adapter (HBA) online, you must disable the I/O paths to the controller. After you replace the HBA, you enable the I/O paths.
To replace a host bus adapter online
Disable the paths to the controller by removing the reference from DMP. Enter the following. In this example, the controller name is fscsi.
# vxdmpadm -f disable ctlr=fscsi
Remove the device references from the operating system. Enter the following:
# rmdev -Rdl fscsi
Rescan the device tree and rebuild the DMP database. Enter the following:
# vxdctl enable
Reconfigure the devices in the operating system. Enter the following:
# cfgmgr
Verify that new devices appear at the operating system level.
# lsdev -Cc disk
Enable the controller. In this example, the controller name is fscsi.
# vxdmpadm enable ctlr=fscsi
Rescan the device tree and rebuild the DMP database.
# vxdctl enable
