Configuration parameters
The KGPSA-CA PCI FC adapter emulation has the following configuration parameters:
Anchor | ||||
---|---|---|---|---|
|
Parameter | storage_controller_path_id | |||
---|---|---|---|---|
Type | Text String | |||
Value | Instructs the CHARON VM to create a set of virtual FC devices and connect to the virtual system through the virtual KGPSA FC Adapter. In this mode WWID and UDID values are taken from the storage controller directly. Note that some storage controllers may not support aquiring UDID, in this case this way of mapping cannot be used in case of OpenVMS (Tru64 Unix is Ok)! Syntax:
where the "Storage controller path ID" parameter is a storage (for example SAN) controller path ID. This ID can be obtained from the "Host Device Check" utility ("Storage Controllers" section): Once specified, all the disks attached to the storage are automatically mapped as disk units to CHARON VM. Example:
It is also possible to use wildcards for specifying the ID number: Example:
In this case CHARON will collect the LUNs from all the matching paths. This syntax works disregarding whether Windows MPIO is active or not. If it is active, CHARON VM uses "active" path (because it works through Windows), if Windows MPIO is OFF, CHARON VM selects the first matching path (and warns you in the LOG file). Note that LUNs obtained by usage of "storage_controller_path_id" parameter is not re-enumerated on reboot, so this mode is possible to use in case of shared disks clusters. |

Parameter | host_bus_location | ||
---|---|---|---|
Type | Text String | ||
Value | Establish connection between virtual DEC-KGPSA-CA PCI FC adapter and physical EMULEX LightPulse PCI/PCI-X/PCIe FC adapter (pass through mode) Syntax:
where X, Y, and Z describe location of physical EMULEX LightPulse PCI/PCI-X/PCIe FC adapter in the host computer (see this section for details). Example:
|
wwid
Parameter | wwid[N] N is 0..32766 (no more than 255 units) | ||
---|---|---|---|
Type | Text String | ||
Value | Sets WWID for emulated KGPSA adapter unit in case if the WWID can not be obtained directly from the device CHARON VM is mapped to. For example in case of disk images or local physical drives CHARON VM cannot get its WWID from the the host system, so it is automaticaly introduce some generated WWID. In case if this WWID is not acceptable it can be replaced with the custom one using the "wwid" parameter. Syntax:
Example:

Parameter | container[N] N is 0..32766 (no more than 255 units) | |||||||||||||||||||||||||
---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
Type | Text String | |||||||||||||||||||||||||
Value | Possible values of the parameter are strings in one of the following forms:
This parameter is initially not set, thus creating NO storage elements on the controller.. |
media_type
Parameter | media_type[N] N is 0..32766 (no more than 255 units) | |
---|---|---|
Type | Text String | |
Value | Instructs CHARON VM to use the supplied value as the PRODUCT field in the FC INQUIRY data returned to a software running on virtual HP Alpha system in response to FC INQUIRY command. If not specified, CHARON VM attempts to guess the FC INQUIRY data based on virtual FC device type and underlying container (which is specified in the corresponding container configuration parameter). Initially is not specified. Example:
|
removable
Parameter | removable[N] N is 0..32766 (no more than 255 units) | |
---|---|---|
Type | Boolean | |
Value | When set to "true", the removable configuration parameter instructs CHARON VM to report the corresponding virtual FC device as removable. By default the removable configuration parameter is set to "false". Example:
