Type of mappingDescription
"<file-name>.vdisk"

Mapping to files representing physical disks of the HP Alpha system (disk images). 
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" 

"/dev/sd<L>"

Mapping to physical disk. "L" is letter here. (warning) 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.

(info) 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.

Note

Since "/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 (see below).


"/dev/dm-<N>"
"/dev/mapper/mpath<N>"
"/dev/mapper/disk<N>"

Mapping to multipath disk. (warning) 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.

"/dev/disk/by-*"

Mapping to physical disk.

  • by-id (addressing by the disk ID, for example "/dev/disk/by-id/ata-ST1000DM003-9YN162_S1D01QJ4")
  • by-label (addressing by the disk label, for example "/dev/disk/by-label/MyStorage")
  • by-uuid (addressing by the disk UUID, for example "/dev/disk/by-uuid/0e808a2f-cdd3-4944-a245-f729ffd73882")

(warning) 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.

"/dev/sg<N>" 

Direct mapping to some SCSI device, for example, a SCSI disk or tape reader.

How to find proper "/dev/sg" device is explined in this section.

"/dev/sr<N>"
"/dev/cdrom"
"/dev/cdrom<N>

Mapping to host CD-ROM device.
"<file-name>.iso"Mapping to an ISO file for reading distribution CD-ROM image.
Mapping may also include the full path (recommended), for example: "/my_disks/vms_distributive.iso"
"<file-name>.vtape"Mapping to the file representing the tape (tape image).
These files are created automatically.
Mapping may also include a full path (recommended), for example: "/my_tapes/backup.vtape"
