Re: what are cciss devices?



.... perhaps a better questiion might be why can I see just three sd
devices with fdisk -l, bjut 5 disk devices including two cciss devices
with lvmdiskscan?

(I have now found that the cciss devices are compaq raid devices :-)

# fdisk -l

Disk /dev/sda: 107.3 GB, 107372544000 bytes
255 heads, 63 sectors/track, 13053 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
