Procedure如何更改 Solaris fdisk 标识符

通过新的 fdisk 菜单选项,可以在新标识符和旧标识符之间来回切换。即使挂载了分区中包含的文件系统,也可以更改 fdisk 标识符。

fdisk 菜单中的两个 type 值反映旧标识符和新标识符,如下所示:

  1. 成为超级用户。

  2. 显示当前的 fdisk 标识符。

    例如:


                Total disk size is 39890 cylinders
    
                Cylinder size is 4032 (512 byte) blocks
    
    
    
                                                  Cylinders
    
         Partition   Status    Type          Start   End   Length    %
    
         =========   ======    ============  =====   ===   ======   ===
    
             1       Active    x86 Boot          1     6       6      0
    
             2                 Solaris2          7  39889    39883    100
  3. fdisk 菜单中选择选项 4,将 fdisk 分区标识符更改回 0x82


    SELECT ONE OF THE FOLLOWING:
    
      1. Create a partition
    
      2. Specify the active partition
    
      3. Delete a partition
    
      4. Change between Solaris and Solaris2 Partition IDs
    
      5. Exit (update disk configuration and exit)
    
      6. Cancel (exit without updating disk configuration)
    
    Enter Selection: 4
    
  4. 选择选项 5 更新磁盘配置并退出。

  5. 如有必要,请从 fdisk 菜单中选择选项 4,将 fdisk 分区标识符更改回 0xbf

    例如:


    Total disk size is 39890 cylinders
    
                Cylinder size is 4032 (512 byte) blocks

      2. Specify the active partition
    
      3. Delete a partition
