Each attached Lenovo Storage V7000 system LUN has a special device file in the
Linux directory /dev.
There is a maximum of 128 Fibre Channel disks
that are based on the major numbers that are available. The entries
for all 128 devices are added by the operating system automatically.
The range of devices are detailed as follows:
- Device range without a subsystem device driver (SDD)
- /dev/sda (LUN 0) to /dev/sddx (LUN 127)
- Device range with an SDD
- /dev/vpatha, vpathb...vpathp (LUN 0)
to /dev/vpathaa, vpathab... vpathzp (LUN 127)
Figure 1 and
Figure 2 show examples of the range for the devices.
