Step-1: Determine the Manufacturer and Model of the HBAs. Fibre Channel (FC) Host Bus Adapters(HBA) are interface cards that connects the host system to a fibre channel network or devices. In addition, two Fibre Channel ELS requests are generated. This is because the target binding is saved by the Fibre Channel driver and when the target port returns, the SCSI addresses are recreated faithfully. The DM Multipath fast_io_fail_tmo option takes precedence over replacement_timeout. RedHat does not recommend using replacement_timeout to override recovery_tmo in devices managed by DM Multipath because DM Multipath always resets recovery_tmo, when the multipathd service reloads.
