Configuration parameters

The I/O Bypass controller has the following configuration parameters:

container

Parameter

container[N]

N is 0..32766 (no more than 64 units)

TypeText string
Value

Possible values of the parameter are strings in one of the following forms:

  • Physical disk
    •  "\\.\PhysicalDrive<X>", where X is 0, 1, … 
      (warning) Be careful not to destroy all the information from the disk dedicated to CHARON VM by mistake. 
      These disks must not be formatted by the host OS. 
      Example:

      set DIA container[0]="\\.\PhysicalDrive1"

      .

  • Physical disk by its WWID 

    • "\\.\PhysicalDrive(DevID=XXX-...-XXXX)"

      (warning) Be careful not to destroy all the information from the disk dedicated to CHARON VM by mistake.

      These disks must not be formatted by the host OS.

      DevID addresses the target physical disk by its WWID (hexadecimal 128-bit identifier assigned to the disk drive by its manufacturer/originator).

      Example:


      Div
      classsmall

      set DIA container[100]="\\.\PhysicalDrive(DevID=6008-05F3-0005-2950-BF8E-0B86-A0C7-0001)"


      .

  • iSCSI disks
    • "\\.\PhysicalDrive(iScsiTarget = <iSCSI target>, LUN = <LUN number>)"

      iScsiTarget addresses the disk by its iSCSI target name.

      LUN specifies LUN on connected iSCSI disk.

      Example:


      Div
      classsmall

      set DIA container[200]="\\.\PhysicalDrive(iScsiTarget=iqn.2008-04:iscsi.charon-target-test1, LUN= 1)"


      .

  • File representing a physical disk of the HP Alpha system (disk image)
    • [<drive>":\"<path-name>"\"]<file-name>[".vdisk"] 
      These files can be created from scratch with "MkDisk" utility. Data and OS disks backups are transferred from the original system via tapes or network and restored into these container files.   
      Mapping may also include the full path (recommended), for example: "C:\My disks\my_boot_disk.vdisk"   
      Example: 

      set DIA container[401]="tru64-v51-system.vdisk"


      Warning

      Using compressed folders to store virtual disks and tapes is not supported

      .

  • Other type of drive, for example magneto-optical drive
    • "\\.\<N>:" 
      Example:

      set DIA container[300]="\\.\Z:"


      Warning

      Using compressed folders to store virtual disks and tapes is not supported

      .

(info) This parameter is initially not set, thus creating NO storage elements on the controller..

removable

Parameter

removable[N]

N is 0..32766 (no more than 64 units)

TypeBoolean
Value

When set to "true", the removable configuration parameter instructs CHARON VM to report the corresponding virtual disk as removable.

Note to set this parameter to "true" if this disk storage element is:

  • Mapped to a host removable device
  • Mapped to a disk image located on a host removable device
  • Mapped to a disk image that has to be renamed/moved/deleted right after dismounting it in the guest OS

By default the removable configuration parameter is set to "false".

Example:

set DIA removable[400]=true
