Driver Parameter | Description | |
|
| |
ql2xloginretrycount | Option to modify the login retry count. | |
ql2xlogintimeout | Login timeout value in seconds. Default is 20. | |
ql2xmaxqdepth | Maximum queue depth to report for target devices. Default is | |
| 32. |
|
ql2xmaxsgs | Maximum scatter or gather entries per I/O request. Default is | |
| 32. |
|
ql2xoperationmode | Option to enable operation mode for 2Gb or 4Gb Fibre Channel | |
| Adapters. For 2Gb Fibre Channel Adapters, set to 0x5 to | |
| enable zero input output (ZIO) mode. For 4Gb Fibre Channel | |
| Adapters, set to 0x5/0x6 to enable ZIO mode. | |
ql2xplogiabsentdevice | Option to enable PLOGI (port login) to devices that are not pres- | |
| ent after a fabric scan. This workaround is required for some | |
| Fibre Channel switch defects. 0 = no PLOGI (default); 1 = per- | |
| form PLOGI. | |
|

ql2xqfullrampup | Number of seconds to wait to begin to | |
| for a device after a | |
| Default is 120 seconds. | |

ql2xusedrivernaming | Enables Consistent Device Naming feature. Default is 0 = dis- | |
| abled, 1 = enabled. | |
| Maximum number of command retries to a port that returns | |
| ||
| by a factor of 2 to determine the number of seconds driver holds | |
qlport_down_retry a | the I/O request.) | |
