  1. Chapter Three Designing The File System

  2. Chapter Objectives • Describe the components of the NetWare file system • Describe the purpose of each NetWare-created directory and Novell-suggested directories • Apply directory design concepts to developing and documenting a directory structure for Universal Aerospace • Use NetWare Administrator to work with files and directories in the NetWare file system • Describe drive pointer types and their purpose • Use Windows along with the MAP command to establish network drive pointers

  3. File System Benefits • Five Categories • Centralized management of data and backups • Improved security • Improved reliability and fault tolerance • Shared and private storage areas • Access to data by many different operating system platforms

  4. File System Components • Volumes • Directories and subdirectories • Files

  5. File System Components

  6. Volumes • With NSS, balanced tress (B-trees) have replaced the File Allocation Table (FAT). • Data is stored on NetWare volumes in blocks. • Suballocation allows data from multiple files to be stored in the same block.

  7. Volume Disk Space Options

  8. Block Suballocation

  9. Volumes • When file compression is enabled, the server will compress all files that haven’t been used for a specified time period. • Expand an existing volume by adding a disk drive to the system and spanning the volume.

  10. Viewing Volume Information • Three methods • Server Console commands (described later) • DOS Commands • NLIST • NDIR • NetWare Administrator

  11. Viewing Volume Information • Using NDIR

  12. Activities - Using NDIR • In the first activity you will use the NLIST command to list volume information stored in the NDS tree. • In the second activity you will use the NDIR command to view physical volume information.

  13. Viewing Volume Information • NDS and the File System are two separate environments. • Using NetWare Administrator you can view and work either NDS tree objects or file system objects. • File system objects are access through volume objects. • It is important to be aware of which environment you are working with when using NetWare Administrator.

  14. Activity - View Volume Information • In this activity you will use NetWare Administrator to view both NDS and physical volume information.

  15. Directories and Subdirectories • Required Directories • LOGIN • Files available before logging in • PUBLIC • Files available after logging in • SYSTEM • Files available only to the network supervisor

  16. Directories and Subdirectories • Other System Directories • ETC • DOC • MAIL • DELETED.SAV

  17. Directories and Subdirectories • Suggested Directories • Application Directories • Shared Directories • User home Directories • DOS Directories

  18. DOS Directories

  19. Establishing the Directory Structure • Define Processing Needs

  20. Establishing the Directory Structure • Designing the Volume Directory Structure

  21. Establishing the Directory Structure • Designing the Detailed Directory Structure

  22. Application Oriented Structure

  23. Establishing the Directory Structure • Create the Structure • Create Directories with NetWare Administrator • Create Directories from Windows Explorer • Create Directories from the DOS prompt • Establish Space Limitations • Prevents a directory and its subdirectories from exceeding the space planned for it.

  24. Activity - Creating Directories • In this activity you will use NetWare Administrator to create the directories shown in figures 3-10 and 3-11.

  25. Activity - Setting Space Limitations • In this activity you will use NetWare Administrator to establish the space limitations defined in Table 3-1 for each of the directories you have created.

  26. Working with Network Files • Copying Files • NetWare Administrator • Windows 95/98 • The NCOPY Command • Moving Directories • Copying and Removing Directories • Renaming Directories

  27. Activities - Working with Files • In the first three activities you will learn how to copy files using NetWare Administrator, Windows Explorer, and the NCOPY command. • In the fourth activity you will use NetWare Administrator to move a directory structure. • In the last two activities you will learn how to use NetWare Administrator to copy, remove, and rename directories.

  28. Viewing File Information • You can view NetWare file system information using in a number of ways. • Network Neighborhood • Double-click the server and volume objects. • Right-click the directory or file and select Properties. • Windows Explorer • Double-click the network drive letter. • Right-click the directory or file and select Properties. • NetWare Administrator • The NDIR command line utility

  29. The NetWare Info tab • From the Properties window of Network Neighborhood or Explorer you can click the NetWare tab to access NetWare file dates and attributes.

  30. The NetWare Rights tab • From the Properties window of Network Neighborhood or Explorer you can click the NetWare Rights tab to access view or change a user’s rights to a directory or file..

  31. File System Rights • Read (R) - Open and read data or run a program. • Write (W) - Change the contents of data in existing files. • Delete (E) - delete files or remove folders. • Create (C) - Create new files or folders. • Modify (M)- Rename files and change attributes. • File Scan (F)- See directory and file names. • Access Control (A)- Assign access rights to users. • Supervisor (S)- All of above. Applies to all folders.

  32. Activity - Accessing File Info • In this activity you will use Windows Network Neighborhood to view statistics about the NetWare file system as well as change user access rights in your folders.

  33. Using NDIR • Access File System Information using Windows or DOS-based NDIR command • Print Directory Information • NDIR [path] [/S] > PRN • Sort File Information • NDIR [path] [/SORT [SI AC OW]] • List Selected Files • NDIR [path] [/SI GR value] [/AC BEF date]

  34. Activities - Using NDIR • Printing Directory Information • In this activity you will use options to view a directory structure, access rights and the amount of space used by a directory structure. • Printing File Information • In this activity you will use options of the NDIR command to viewdate information and find a file. • Sorting File Information • In this activity you will use the SORT option of the NDIR command to sort file lists by name, access date, and owner. • Listing Selected Files • In this activity you will use options to list files selected by access date, size, owner, or a combination of parameters.

  35. Activity - Salvage Files • When files are deleted from a NetWare server there contents are kept until the server needs the disk space and are then used in a last deleted last used order. • In these activities you will learn how to use the salvage option of Network Neighborhood to restore deleted files. • In the first activity you will delete all files with the .FRM extension from your Forms directory. • In the second activity you will use Network Neighborhood to browse to your ##Corp directory and then Right-click forms and select the Salvage Option.

  36. Activity - Purging Files • For security purposes or to more quickly make disk space available to the server, you can choose to purge directories and files. • In this activity you will use the Purge Files option from Network Neighborhood to purge all deleted files from your Utility directory.

  37. Drive Pointers • Local Drive Pointers are usually designated A-E • Network Drive Pointers are usually designated F-Z

  38. Network Drive Pointers • Regular Drive Pointer • Shows all directories and subdirectories leading to the storage area. • Root Drive Pointer • The path does not show. • The drive letter appears as if it starts at the root of the volume.

  39. Regular and Root Drive Pointers

  40. Search Drives • Regular or Root Drive Pointers that have been added to the DOS path. Search drives are used to find software that is not located in the workstation’s current default directory.

  41. Drive Letter Usage

  42. Planning Drive Mappings • Typical drive pointers for each user should include the following (usually no more than five) • Drive pointer to the root of each volume • Root drive pointer to the user’s home directory • Root drive pointer to the user’s workgroup directory • Application drive pointers

  43. Universal Aerospace Pointer Usage

  44. Suggested Drive Pointer Assignments • F drive pointer to the SYS volume • G drive pointer to the root of the CORP volume • H drive pointer to the user’s home directory • L drive pointer to each user’s workgroup • Search drive pointers for the SYS:Public directory and utility programs

  45. Establishing Drive Pointers • From login scripts. • Use the MAP command. • From Windows. • Use Windows Explorer or Network Neighborhood. • Reconnect at login • From the DOS command prompt or batch files.

  46. Activity - Mapping From Windows • In this activity you will practice using Windows to assign drive pointers by assuming you are at Kellie’s workstation and applying the drive pointer usage chart developed in Table 3-2.

  47. Specifying Network Paths • Physical volume name contains the NetWare server name, a backslash, and the volume name • A Relative Path begins from the current directory and leads to the desired file or subdirectory

  48. The MAP Command • A command-line utility used to create, modify, and delete regular and search drive pointers. • MAP [root] drive:=[path] • Use [root] option to make the drive a root mapping. • MAP NEXT [path] • Assigns the next available drive letter to the path. • MAP [ins] S#:=[path] • Search drive mapping, replace # with value 1-16

  49. Activities - Using MAP Commands • In the first activity you will learn how to use the MAP command to view, create, and remove regular and root drive pointers. • In the second activity you will use the MAP command to insert and delete search drives.

  50. Directory Map Objects • An NDS object used to stores the physical path to a directory in the NDS tree. • Makes path available to multiple user and container login scripts. • Provides simplified maintenance of drive mappings by allowing changes to the path to be made in only one location. • Users must be given file system access rights to the directory as well as NDS rights to read the path property of the Directory Map Object.
