Accessing a file system from the Shell
Switch from the Shell to a file system before executing commands requiring file input or output.
To switch to a file system:
1.
Using HDD, USB, or iLO virtual USB, attach a FAT16 or FAT32 formatted file system.
2. Use the map –r command to refresh file system mappings. See “map” (page 40) .
3. Enter one of the fsx file systems available, such as fs0 or fs1, and then press Enter.
The prompt changes to fsx>, where x is the number of the file system selected.
Files can now be accessed and written to any writable files in the specified file system.
Example 10 (page 20) shows how to access the fs0 file system from the Shell.
