san disk resize problem


I had a 10gig disk presented to my slamd64 linux box.

I unpresented it. increased its size and represented it.

i then rescanned the scsi bus using

echo "- - -" > /sys/class/scsi_host/host1/scan

but i now get fdisk reporting that the drive is still the orignal size and the kernel ring buffer has the following in it

end_request: I/O error, dev sde, sector 0
Buffer I/O error on device sde, logical block 0
Buffer I/O error on device sde, logical block 1
Buffer I/O error on device sde, logical block 2
Buffer I/O error on device sde, logical block 3
Buffer I/O error on device sde, logical block 4
Buffer I/O error on device sde, logical block 5
Buffer I/O error on device sde, logical block 6
Buffer I/O error on device sde, logical block 7
sd 1:0:3:1: Device not ready.
end_request: I/O error, dev sde, sector 0
Buffer I/O error on device sde, logical block 0
sd 1:0:2:1: Device not ready.
end_request: I/O error, dev sdd, sector 0
Buffer I/O error on device sdd, logical block 0
Buffer I/O error on device sdd, logical block 1
sd 1:0:2:1: Device not ready.
end_request: I/O error, dev sdd, sector 0
sd 1:0:3:1: Device not ready.
end_request: I/O error, dev sde, sector 0
sd 1:0:3:1: Device not ready.
end_request: I/O error, dev sde, sector 0

lsscsi gives the following
root@scarab:/home/ronan/GD-2.30# lsscsi
