To create a virtual disk container file, click on Create Virtual Storage in the SCSI device Virtual Machine Settings window. This displays the Create Virtual Storage dialog opened on the virtual disk tab as shown below.
To create a virtual disk container file, follow the instructions below:

Before the disk can be used by the Solaris guest system, it must be added to the system configuration and formatted by the Solaris guest according to the customer specific requirements.
...
1. Guest system: rewind tape if required, write content to it, and “eject” it:
|
2. Host system: use sftp to rename/copy the original container file and to copy a new empty file with the same name in its place.
3. Guest system: display tape status (thereby loading the new file), rewind tape if required, and write content to it:

Adding or Editing a Virtual SCSI Device

In both cases, a window similar to the one below opens with the configuration parameters of the virtual SCSI device.

Charon-SSP does not place any restrictions on the bus and SCSI target ID used for emulated SCSI devices, e.g., a virtual CD-ROM. However,
If you encounter the problem that the CD-ROM is not found when trying to boot from it, verify its expected location in the OBP environment ( |
The following table lists the fields in the Add/Edit SCSI Device configuration window and describes their use.
Add/Edit virtual SCSI device configuration fields | |||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
| Fields | Description | ||||||||||
SCSI bus | Specify either the Primary SCSI Bus or the External SCSI Bus. Please note: Charon-SSP/4M has only one SCSI bus. | ||||||||||
SCSI ID | SCSI device target ID:
| ||||||||||
LUN ID | SCSI device LUN ID. A SCSI device is identified by a combination of bus, target ID (SCSI ID), and LUN ID. This parameter must be configured to match the storage device configuration. Valid IDs are 0 through 7. Default value is 0.
| ||||||||||
Removable | Default: OFF. If enabled, the emulator will start even if the device/file does not exist on the host. | ||||||||||
SCSI device type | Drop-down list of configurable device types. Available device types:
| ||||||||||
SCSI device path | Click on the path button to specify the location of the virtual SCSI device. This will open a file browser. To sort the file browser display by name, click on the corresponding heading. Select an appropriate device or file using the file browser, or type the correct name in the file name field. Note: if you manually enter a device name instead of selecting a device from the file browser window, make sure that the file/device exists (relative to the path of the opened file browser) or is set to removable. The list below shows sample device paths for each SCSI device type option:

Physical Disk Parameters on Charon-SSP
The Charon-SSP virtual machines offer additional options when adding physical disks as virtual SCSI devices. The windows for adding a new device and for editing an existing device contain the same fields. The configuration windows are different for Charon-SSP/4U(+)/4V and Charon-SSP/4M because only Charon-SSP/4U(+)/4V support a second SCSI bus. The two different configuration windows are shown below:
Add physical disk on Charon-SSP/4U(+)/4V | Add physical disk on Charon-SSP/4M |

The following table describes the additional parameters available for physical disks on Charon-SSP:
Additional physical disk parameters | |
|---|---|
| Field | Description |
Pass through | You can select OFF (default) or ON. SCSI pass-through is used to allow direct access to SCSI devices. Such devices can be locally or remotely connected SCSI storage devices (e.g., local disks, iSCSI connected disks, Fibre Channel disks, etc.) and other SCSI devices that support the SCSI command set. On the host side, this feature depends on the generic SCSI driver (SG) capabilities of the host operating system. The emulator does not depend on particular adapter types. This feature is useful, for example, for using shared disks in cluster environments (fencing / persistent reservations) and special SCSI peripherals, such as tape robots or SCSI-connected serial devices and scanners. |
Serial Number | The serial number is a physical characteristic of hard disks and is used mainly to persistently and unambiguously identify iSCSI mapped disks (and possibly Fibre Channel disks), for which the device identification on the host (i.e. /dev/sdX) may change when the host system reboots. If the Serial Number field is enabled, the field SCSI device path is disabled. You can find the serial number using the Storage Manager that is started from the Tools > AWS Cloud menu of the Charon-SSP Manager. |
