this is also dependant on the HBA you are using. With a Qlogic adapter
you can simply send an:

echo scsi-qlascan
to your Qlogic adapter (for example under /proc/scsqi/qla2xxx)

thanks for attention, guys

Sebastian, yes, I use qlogic, but, you will laught, I have not /proc/scsqi/qla2xxx. googling around shows that: "as of RHEL4 U3 (and I'd imagine upstream kernel.org kernels) the 'scsi-qlascan' no longer works with the qla2xxx driver. The new method is:

echo 1 > /sys/class/fc_host/host<ID>/issue_lip
echo "- - -" > /sys/class/scsi_host/host<ID>/scan" but it does not work for me.
I tried "echo 1 > /sys/devices/pci0000:00/0000:00:03.0/0000:04:00.0/0000:06:01.0/host1/rport-1:0-1/target1:0:1/1:0:1:2/rescan" too. so, it was much better: dmesg showed me disks with new capacity, but "fdisk -l" still showing old capacity;( any thoughts?
