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

• Physical disk
  • "/dev/sd<L>" where "L" is letter.
  • "/dev/disk/by-id/..." - addressing by the disk ID, for example "/dev/disk/by-id/ata-ST1000DM003-9YN162_S1D01QJ4"
  • "/dev/disk/by-label/..." - addressing by the disk label, for example "/dev/disk/by-label/MyStorage"

  • "/dev/disk/by-uuid/..." - addressing by the disk UUID, for example "/dev/disk/by-uuid/0e808a2f-cdd3-4944-a245-f729ffd73882"
    Be careful not to destroy all the information from the disk dedicated to CHARON-AXP by mistake.
    

    Note
    "/dev/sd<L>" addressing is not persistent, so it is strongly recommended to use "/dev/disk/by-id/wwn-*" syntax instead to refer the disk by its WWID - especially in the enviroments utilizing FC and SAN storages.

     These disks must not be formatted by the host OS.

    Example:
    

    set DIA container[0]="/dev/sdb"

    It is also possible to use not a whole disk, but previously created partitions on it. In this case the syntax is the following: "/dev/sd<L><N>" where N is the number of partition to be used. 

    Example:

    set DIA container[0]="/dev/sdc1"

    .

• Multipath disk
  • "/dev/dm-<N>" 
  • "/dev/mapper/mpath<N>" 
  • "/dev/mapper/disk<N>" 
     Be careful not to destroy all the information from the disk dedicated to CHARON-AXP by mistake.  

    These disks must not be formatted by the host OS.

    Example:

    set DIA container[100]="/dev/dm-0"

    .

• Loop (virtual block) devices

  • "/dev/loop<N>"
    Example:

    set DIA container[200]="/dev/loop0"

    
    
    

• Direct mapping to some SCSI disks
  

  • "/dev/sg<N>"
    Example:

    set DIA container[300]="/dev/sg0"

    .

  ISO file for reading distribution CD-ROM image
  • [<drive>":\"<path-name>"\"]<file-name>[".iso"]
     Mapping may also include the full path (recommended), for example: "/my_disks/vms_distributive.iso"

    Example:

    set DIA container[600]="/my_disks/vms_distributive.iso"

    .

• 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 "mkdskcmd" utility. Data and OS disk backups are transferred from the original system via tapes or network and restored into these container files.   

    Mapping may also include the full path, for example: "/my_disks/my_boot_disk.vdisk"

    Example:

    set DIA container[401]="my_dka401.vdisk"

    
    

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

This formatted string value specifies the explicit geometry of the disk storage element. This parameter is not applicable to tape storage elements.

The string format is ”*/*/*/<B>" or ”*,*,*<B>" where B is the total size of the disk (in blocks) reported to the guest OS. If omitted it is calculated automatically.

If this parameter is not set, CHARON VM will configure the geometry based on the most probable disk type.
