Figure 4-3 Entering EFI shell
This mapping table lists both block devices (blk) and file systems (fs). All fixed
disks, CD-ROM drives, and USB storage devices will appear as block devices. If
the server contains additional controllers and disks, they will appear as additional
block devices. The EFI automatically maps known file systems on the block
devices to their FSx mappings (FSx is referred to as the
file system identifier
).
Here are some tips for easier identification of devices in the list:
Even with no storage devices, the server has at least two default mappings,
the MemMap entries listed as
fs0:
and
fs1:
in Figure 4-3. These are
read-only RAM disks created during POST, so they will always be available.
The first MemMap file system is the content of the 4 MB of NVRAM assigned
to the EFI and contains a number of drivers. The second MemMap file system
is the content of the NVRAM assigned to the server diagnostics.
