Every instance of KGPSA-CA works in one of the two following modes:
- Fabric virtualization mode 695402720 (creating virtual fabric in combination with virtual FC-3 Storage Controller). This is default mode.
- Pass Through mode 695402720 (using a specific CHARON PCI Pass Through driver)
- Fabric presentation mode 695402720 (using Linux FC HBA directly)
...
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.
Example:
load kgpsa_generic_storage PGA lun_include="6008-05F3-0005-2950-C758-BCC2-E88B-0007,6008-05F3-0005-2950-8B03-E26B-E231-0005" |
...
load kgpsa_generic_storage PGA revision_id=0x01 |
scsi_serialize_io
This parameter controls serialization of the SCSI requests.
| Value | Description |
|---|---|
false | Responses delivered to the emulated KGPSA card in order they were submitted to Linux. This is the default value. |
true | Responses delivered to the emulated KGPSA card in order they were completed by Linux |
| Note |
|---|
This parameter is needed for some specific cases only, so it is strongly recommended not to specify any value without particular instructions from Stromasys. |
Example:
load kgpsa_generic_storage PGA scsi_serialize_io = true |
scsi_max_queue_depth
This parameter sets limitation of the SCSI queue depth per LUN
| Value | Description |
|---|---|
unlimited | Linux SG I/O applies limitation of 16 I/Os. Requests are submitted unless write to SG I/O fails. This is the default value. |
1...16 | Only the specified number of the requests are submitted in parallel. |
| Note |
|---|
This parameter is needed for some specific cases only, so it is strongly recommended not to specify any value without particular instructions from Stromasys. |
Example:
load kgpsa_generic_storage PGA scsi_max_queue_depth = 1 |
