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?
