Hi, On 2.6 kernels, I always used to issue the commands directly:
1) Find what's the host number for the HBA: ls /sys/class/fc_host/ (You'll have something like host1 or host2, I'll refer to them as host$NUMBER from now on) 2) Ask the HBA to issue a LIP signal to rescan the FC bus: echo 1 >/sys/class/fc_host/host$NUMBER/issue_lip 3) Wait around 15 seconds for the LIP command to have effect 4) Ask Linux to rescan the SCSI devices on that HBA: echo - - - >/sys/class/scsi_host/host$NUMBER/scan The wildcards "- - -" mean to look at every channel, every target, every lun. That's it. You can look for log messages at "dmesg" to see if it's working, and you can look at /proc/scsi/scsi to see if the devices are there. These commands should work with all HBAs, at least I know for sure they work with QLogic's and Emulex'es. Hope it helps, Filipe
