SCOadmin Storage Managers

SCOadmin Storage Managers

The SCOadmin Storage Managers provide a graphical interface to disk storage management. These managers can be used as an alternative to the diskadd(1M) and disksetup(1M) utilities that provide the traditional command line disk setup interface.

The following managers are grouped together under the Storage folder in the main SCOadmin window, displayed by selecting SCOadmin from the Desktop menu, or by entering scoadmin at a command shell prompt.


Disk Manager
Displays all disks currently connected to the system, The Disk Manager supports the following major operations on the disks appearing in the main window:

Partition Manager
Displays the partitions defined on currently defined disks. If launched from the Disk Manager, it displays the partition layout for the currently selected disk; launched from the SCOadmin menu or from the command line (scoadmin partition), it displays the partitions on all defined disks. All partitions on the disk are displayed, whether they are UNIX system partitions or any other type. The Partition Manager supports the following operations on a disk:

Slice Manager
Displays the slices defined on currently defined UNIX System partitions. If launched from the Disk Manager, the slices defined for the active UNIX System partition on the currently selected disk are displayed. If launched from the SCOadmin main menu or the command line (scoadmin slice), the active partitions on all disks are displayed.

When a UNIX System partition is created with the Partition Manager, a default slice layout is used, with a vxfs file system as the root of the disk. The layout depends on the size of the disk and other factors.

The current version of the Slice Manager will only display slices/file systems. Future versions of the Slice Manager will support the following operations on a disk:

Adding a Second Disk

The procedure in this section shows you how to use the Disk Manager and associated managers and tools to:

  1. Check the current disk configuration; launch the Disk Manager from the SCOadmin main menu, or by entering:
       scoadmin disk
    

  2. Use dcu(1M) to ensure that the required drivers for the disk and controller are installed. See `` Viewing or changing device driver configuration''.

  3. If the disk is not a plug and play (or hot-add) device, shut the system down, by entering the following at a shell prompt:
       shutdown -i0 -g0 -y
    
    Wait until the system is down and turn the power off.

  4. Follow the manufacturer's directions to configure any jumpers, SCSI IDs. SCSI terminators, or other settings required on the disk before installing it into the system. If necessary, install a controller for the disk; see `` Configuring hardware controllers''. Once the disk is installed, turn the system on.

  5. When the system reboots, it should create device nodes for the new disk. Launch the Disk Manager as shown in Step 1. It should list the new disk.

  6. Highlight the new disk and select the Partition icon on the icon bar (or select Operations>Partition from the menu). The Partition Manager main window is displayed, showing the disk you selected. If this is a new disk with no partitions defined, the Type column for the disk will display Undefined. To re-partition a disk, first delete all partitions by highlighting them and selecting the Delete icon or Partition>Delete from the menu. Note: This will delete all information on the disk.

  7. Create the first partition by highlighting the disk and selecting the Create icon or Partition>Create from the menu. The Create Partition window is displayed.

  8. Choose appropriate values for the following options:

    Type Choose UNIX System for partitions you want to use with UnixWare; DOS or Other for partitions you want to use with other Operating Systems.
    Active Select this option if the partition is to be the Active partition on the disk. Only an active partition can be mounted, and there can be only one active partition per disk.
    Size Use the slider bar to allocate a percentage of the available disk space to the partition. The slider will not move beyond the percentage of currently available space on the disk.

    For our example, select UNIX System, Active, and 50% of the disk for the first partition. Select OK.

  9. The Partition Manager main window should now display information for the UNIX System partition you just created. Use the View>Cylinders menu command to add cylinder information to the default display.

  10. To create the second partition, which we'll use for another operating system, highlight the disk and select the Create icon or Partition>Create from the menu. The Create Partition window is displayed.

  11. For this partition, choose Other for the Type, do not select the Active check box, and leave the Size slider bar at 50% (allocating the remainder of the space on this disk to the second partition). Select OK.

  12. The Partition Manager main window should now display information for the Other partition you just created. Select Host>Exit to go back to the Disk Manager window.

  13. Highlight the disk and select the Slice icon or the Operations>Slice command from the menu. The default slices defined on the partition when it was created are displayed.

    To change the slice layout of the partition, use the diskadd(1M) or disksetup(1M) commands (diskadd is an interactive interface to disksetup). Once you are done, select View>Refresh to see your changes in the Slice Manager.

    To define a file system on a slice, use the mkfs(1M) command, using the Sector Length displayed in the slice Manager as the size of the new file system. Once you are done, select View>Refresh to see your changes in the Slice Manager.

  14. To mount a newly created file system, use the Filesystem Manager (scoadmin filesystem), or click on Filesystem Manager in the Storage folder on SCOadmin's main menu. Select on Mount>Add mount configuration>Local from the menu, and fill in the fields as explained below:

    Device File The device name for the file system you are mounting is displayed in the Slice Manager window. Choose the same device from the drop-down box.
    Mount Point Enter the name of the directory where you want to mount the file system (e.g., /home2). The directory must already exist.
    Description Optional description.
    Filesystem Type Selected automatically according to the device chosen; cannot be changed.
    Access Mode Select Read-only or Read-Write.
    When to Mount Select Now to mount the file system immediately. Select At System Startup to have the file system mounted automatically when the system boots.
    Advanced Options This button, if enabled, opens another window where you can set additional file system options if any exist for the file system type being mounted. The options presented vary by file system type, and are explained briefly with point help at the bottom of the window. Select OK when you are done setting advanced options.

    See the mount(1M), mount_vxfs(1M), and other file system specific mount commands for an explanation of file system mount options. Select OK when you are done setting file system mount options.

  15. The Filesystem Manager now displays the mounted file system in the main window. Close the File System Manager, the Slice Manager, and the Disk Manager by selecting Host>Exit from the menus.
