Every instance of KGPSA-CA works in one of the two following modes:

...

Fabric virtualization mode (creating virtual fabric in combination with virtual FC-3 Storage Controller). This is default mode.

...

Pass Through mode (using a specific CHARON PCI Pass Through driver)

...

Fabric presentation mode (using Linux FC HBA directly)

Configuration parameters

The KGPSA-CA PCI FC adapter emulation has the following configuration parameters:

host_bus_location

Parameter host_bus_location

Type Text String

Value

695402720 Pass Through mode only !

Establish connection between virtual DEC-KGPSA-CA PCI FC adapter and physical EMULEX LightPulse PCI/PCI-X/PCIe FC adapter (695402720 Pass Through mode)

Syntax:

load KGPSA <controller name> host_bus_location="/dev/kgpsa<X>"

Example:

load KGPSA FGA host_bus_location="/dev/kgpsa0"

wwid

Parameter

wwid[N]

N is 0..32766 (no more than 255 units)

Type Text String

Value

Sets WWID for emulated KGPSA adapter unit.

Syntax:

set <controller name> wwid[unit-number]="XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX-XXXX"

Example:

set FGA wwid[2]="6008-05F3-0005-2950-BF8E-0B86-A0C7-0001"

container

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:

Physical disk

"/dev/sd<L>", where "L" is letter, for example "/dev/sdb"
"/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"
Please note that existing data on such a disk may be destroyed, depending on how it is used in the emulator.

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 FGA container[0]="/dev/disk/by-id/ata-ST1000DM003-9YN162_S1D01QJ4"

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 FGA container[0]="/dev/sdc3"

.Loop (virtual block) devices

Loop (virtual block) devices
- "/dev/loop<N>"
  Example:
  set FGA container[100]="/dev/loop0"
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 FGA container[200]="/dev/dm-0"
  .
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 (recommended), for example: "/my_disks/my_boot_disk.vdisk"
  Example:
  set FGA container[401]="my_dka401.vdisk"
  .

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

Div

class	pagebreak

media_type

Parameter

media_type[N]

N is 0..32766 (no more than 255 units)

Type

Text String

Value

Instructs CHARON-AXP 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-AXP 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:

set FGA media_type[0]="HSZ70"

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-AXP to report the corresponding virtual FC device as removable.

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

Example:

set FGA removable[400]=true

Div

class	pagebreak

geometry

Parameter

geometry[N]

N is 0..32766 (no more than 255 units)

Type

Text String

Value

This formatted string value specifies the explicit geometry of the disk storage element.

The string format is <X>”/”<Y>[“/”<Z>] or <X>”,”<Y>[“,”<Z>][“,”<B>] where:

Parameter	Description
X	The number of sectors per track
Y	The number of tracks per cylinder
Z	The number of cylinders on the unit. If omitted, Z is calculated based on X, Y and the total number of sectors on the unit that reflects the size of the disk storage element. This is an optional parameter.
B	The total size of the disk (in blocks) reported to the guest OS. If omitted it is calculated automatically. This is an optional parameter.

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

Initially not set.

Example:

set FGA geometry[201] = "255/255"

Info

It is possiblle to specify each parameter independently of another one. The following syntax is used for that:

set FGA geometry[300]="*,*,*,16777210"

use_io_file_buffering

Parameter

use_io_file_buffering[N]

N is 0..32766 (no more than 255 units)

Type

Boolean

Value

When set to "true", instructs CHARON-AXP to enable host operating system I/O cache on read/write operations.

Note that this caching has a significant effect only in case of mapping to disk containers, not physical drives.

When enabled, host operating system I/O cache may significantly improve I/O performance of the virtual system. At the same time maintaining I/O cache requires additional host resources (CPU and memory) which may negatively affect overall performance of the virtual system.

Initially is set to "false".

Example:

set FGA use_io_file_buffering[300]=true

Div

class	pagebreak

io_queue_depth

...

set FGA container[0]="/my_disks/my_dka401.vdisk"set FGA container[100]="/dev/sdb"
set FGA container[200]="/dev/sdc2"
set FGA container[300]="/dev/dm-0"

See the "695402720 Configuration parameters" section for details.

The CHARON-AXP FC Fabric presentation mode allows to use Linux FC HBA directly. When using this mode, there is no need to load KGPSA adapter(s) as it was described before. The following syntax has to be used instead:

Example:

load kgpsa_generic_storage PGA interface="host3"

...

The list of the LUNs to be excluded. If empty (default), nothing is excluded.
No multi line is possible for this parameter; the maximum number of symbols inside the double quotes is 255. Use "lun_include" parameter instead if a lot of LUNs must be excluded to specify only the included LUNs.

Example:

load kgpsa_generic_storage PGA lun_exclude="6008-05F3-0005-2950-C758-BCC2-E88B-0007,6008-05F3-0005-2950-8B03-E26B-E231-0005"

...

The list of the LUNs to be included. If empty (default), all LUNs are included.
No multi line is possible for this parameter; the maximum number of symbols inside the double quotes is 255. Use "lun_exclude" parameter instead if a lot of LUNs must be included to specify only the excluded LUNs.
