HBA is a controller/network card which connects a host system (computer) to other network and storage devices, primarily used with controllers that connect to SCSI, Fibre Channel and eSATA devices
[edit]
- Identify your HBAs in Linux:
- Fibre Channel LUN Scan or
rescan-scsi-bus.sh:echo "1" > /sys/class/fc_host/host1/issue_lip(No output from command) orrescan-scsi-bus.sh -iecho "- - -" > /sys/class/scsi_host/host1/scanlsblk -S
